Preserve Buddy as the default general-purpose primary agent, route lifecycle commands through Orchestrator, support bounded prompt-coordinated parallel Builders and Librarians, and keep issue #100's GitHub bot behavior outside this issue. + +## Requirements & Decisions + +- **Frameworks:** Use the existing OpenCode Markdown agent/command framework, foreground and experimental background Task delegation, Task session continuation through `task_id`, path-scoped permissions, the repository's Planner/PlanReviewer and Builder/Testing/CodeReviewer/Committer loops, and `agent-harness/bin/harness-sync.sh`. The authoritative harness is `agent-harness/`; `.opencode/` and root `opencode.jsonc` are synchronized project copies, while `opencode/opencode.jsonc` is maintained separately. OpenCode—not agent prompts—supplies foreground waiting, child sessions, `task_id` continuation, background jobs, and completion events. Restart OpenCode after configuration synchronization and before discovery/runtime checks. +- **Chosen Libraries:** None. OpenCode already supplies agent modes, Task delegation, child session IDs, background execution, permissions, and depth controls. Prompt-coordinated shared-worktree scheduling was explicitly chosen over Git worktrees or a SQLite claim ledger because worktrees would require expanding the Nono sandbox. This is a cooperative coordination mechanism, not an atomic filesystem safety boundary. +- **Error Handling Strategy:** Follow “fail loud, never fake.” Orchestrator preserves the child error and reports phase, task/topic, session ID when available, and attempt count. A technical failure is Task state `error`/`cancelled`, timeout/API/tool error, unavailable session, step-limit termination without the required result, or a terminal result whose single fenced JSON object is missing, invalid, nonterminal, mismatched to the assigned ID, lacks required keys, or reports unaccounted paths. Each child follows the cooperative prompt protocol `queued → running → resume-running → continuation-running (Builder only) → succeeded | exhausted`; Orchestrator records state, session ID, claim, baseline, attempt, and result in its session context. On initial technical failure, retain claims and resume that `task_id` once. A still-failing Builder gets one fresh continuation session instructed to inspect and continue partial work; any other child becomes exhausted. Already-running peers may finish, no new batch task dispatches after a failure, and retry/correction Builders count toward the two-active limit. Review starts only when every batch task succeeded; any exhausted task aborts the batch without testing, review, or commit and leaves changes visible. Normal review critique, Testing nonzero exit, user rejection, and deterministic precondition failures are correction/precondition outcomes, not technical retries. If a call with `background: true` is rejected because the parameter/capability is unavailable—unknown argument/schema error or an explicit disabled-background error—treat it as a non-retryable missing-core-feature precondition, disclose it, and stop rather than run serially. Prompts cannot inspect the process environment before this attempt. Scheduling, limits, claims, barriers, result interpretation, and retries are cooperative session-local protocol—not plugin-enforced, transactional, durable, or safe across independent sessions—and documentation/acceptance must not claim otherwise. +- **Scope Boundary:** Implement the orchestration architecture requested by issue #101 only. Do not implement issue #100's GitHub issue polling, bot-comment detection, research-comment publication, or integration-bot behavior. Leave `/archive_plan` assigned to Buddy and functionally unchanged; its pre-existing archive-path, ownership, and post-mortem inconsistencies are out of scope. +- **Primary-Agent Decision:** Buddy remains the general-purpose primary agent and is explicitly selected through OpenCode's `default_agent` setting. Orchestrator uses `mode: all` so it is selectable and callable by Buddy/commands. Buddy's Task allowlist is exactly Orchestrator, Explorer, and Librarian; lifecycle intent must pass through Orchestrator. Buddy asks one question when routing is ambiguous and refuses a lifecycle bypass. +- **Question Flow:** Planner runs as a foreground Task child with `question: allow`. Current OpenCode Task/Question services associate the pending question with the child session, render it in the shared UI, keep the parent waiting, and resume the child after reply. Runtime-smoke this source-verified behavior; if the installed version does not render it, stop as incompatible rather than invent a relay. Never run interactive planning in the background. +- **Delegation Permissions:** Every harness agent uses deny-by-default Task mappings. Buddy denies `*` and allows only `Orchestrator`, `Explorer`, and `Librarian`; Buddy is the sole agent allowed to target Orchestrator. Orchestrator denies `*` and allows only `Planner`, `Builder`, `Testing`, `PlanReviewer`, `CodeReviewer`, `Explorer`, and `Librarian`, but cannot target itself. Planner denies `*` and allows only Explorer, Librarian, PlanReviewer. Builder denies `*` and allows only Committer. PlanReviewer and CodeReviewer deny `*` and allow only Explorer/Librarian. Explorer, Librarian, Testing, Committer, and DocumentationEngineer deny Task entirely. Any other installed/system agent is outside the harness graph and must not be referenced by harness prompts; project config disables built-in `plan`, `build`, `general`, and `explore` to prevent bypass. +- **Task Graph:** `PLAN.md` is canonical. IDs match `[A-Z][A-Z0-9_-]*` and are unique; dependencies are `None` or existing IDs. Resolve repository root with `git rev-parse --show-toplevel`; reject absolute paths, empty paths, NUL/newline, `.`/`..` segments, unresolved paths outside the root, symlinks at any existing component, and case-fold collisions. Normalize `/`, duplicate separators, and trailing `/`. Literal scopes overlap on equality/ancestor relation. Glob scopes permit only `*`, `?`, and `**`; compute fixed literal prefixes and treat equal/ancestor prefixes or any indeterminate intersection as conflict. Renames require ownership of both old/new paths. Shared-resource names conflict on equality or `/` ancestor relation. Diagnose duplicate/unknown/self dependencies, then detect cycles by deterministic ID-sorted DFS; a task is dependency-ready only when every prerequisite is `[x]`. Parallel dispatch requires `[ ]`, `Parallel Safe: Yes`, ready dependencies, and pairwise nonoverlap. Approval means the latest populated Plan Review entry is exactly `Approved`. `check-plan-graph.py` implements this same algorithm; Orchestrator may add metadata but never while Builders run. +- **Implementation Scheduling:** `/continue_implementation` replaces `/implement_next_task`. It selects at most two approved, dependency-ready, explicitly parallel-safe tasks with disjoint normalized repository-relative owned paths/shared resources; arguments may narrow IDs or force serial execution. Orchestrator tracks cooperative claims in-session. Before dispatch and each review, it invokes Explorer in foreground to capture baseline/current commit and dirty/staged paths through exactly `git rev-parse HEAD`, `git status --porcelain`, `git diff --name-only`, and `git diff --cached --name-only`. It compares snapshots with declared ownership and known batch outputs and stops on overlap, unknown dirty/staged path, alias/symlink, or indeterminate state. Snapshots and prompts do not atomically protect against another process, disobedient agent, or undeclared/generated files. +- **Batch Barrier:** Background Builders implement only assigned scope and do not edit `PLAN.md`, test, review, or commit. Orchestrator waits for all Builders and applies the retry protocol while retaining claims. If all succeed, finalize one task at a time: Explorer confirms paths and empty index; Orchestrator changes only that task to `[/]`; foreground Testing runs approved validation; CodeReviewer receives task ID, baseline, exact diff/scope, and test result. Testing failure or review rejection appends critique only and never sets `[x]`; Orchestrator resumes the corresponding successful Builder session with exact feedback, then repeats snapshot, Testing, and review. Each task has at most three validation/review rounds, independent of technical retries. Only accepted review sets `[x]`. The same Builder then invokes Committer with owned paths plus that task's serialized `PLAN.md` change. Committer tolerates known dirty peer-task paths but requires an initially empty index, stages only its allowlist plus `PLAN.md`, verifies cached paths exactly, and aborts on unknown dirt or out-of-scope staged paths. Record baseline/resulting paths, then finalize the next task. If any Builder exhausts recovery, no batch task is tested, reviewed, or committed. +- **Research Scheduling:** `/research` routes to at most four background Librarians. Resolve the Git root, Unicode-normalize topic/target to NFC, case-fold only for collision keys, convert separators to `/`, collapse duplicates, and reject absolute paths, NUL/newline, empty/`.`/`..` segments, non-`.md` targets, targets outside `docs/research/`, symlinks in every existing component, a non-directory parent, or a case-fold collision. Nonexistent final files are allowed only when all parents exist as real directories. Within one live Orchestrator session, sort requests by `(topic-key,target-key)`, reserve all keys in memory before dispatch, and reject duplicate topic or target. Reservations intentionally end with that Orchestrator session and provide no restart/cross-process guarantee. A new session performs only filesystem collision checks: existing target requires explicit update mode; absent target may dispatch after warning that another process cannot be detected. Do not infer old child status/topic/target from OpenCode session metadata and do not claim restart reconciliation. Verification belongs to issue #85. +- **Command Preconditions:** `/plan` asks before replacing a non-empty `PLAN.md`. `/continue_implementation` stops when `PLAN.md` is missing, structurally invalid, unapproved, has no open dependency-ready task matching the request, or conflicts with an active claim. `/review_plan` stops without a plan. `/review_code` stops without both a plan and an identifiable task/change scope; it no longer performs an unscoped general review. These deterministic failures are reported without retry. +- **Structured Result Parsing:** Builder and Testing emit exactly one final fenced `json` block. Reject duplicate blocks/keys, unknown keys, wrong types/nulls, invalid status/path/ID/session, command mismatch, and unowned paths. Builder schema is exactly `{task_id: string, status: "succeeded"|"failed", baseline: 40- or 64-lowercase-hex Git ID, modified_paths: unique array, validation_requested: unique array, concerns: array, session_id: nonempty string}`. Testing schema is exactly `{task_id: string, status: "passed"|"failed"|"blocked", commands: ordered array<{command: string, exit_code: integer|null, status: "passed"|"failed"|"blocked", summary: string}>, concerns: array, session_id: nonempty string}`. Each result `session_id` must equal the current Task envelope's child-session ID, including every resumed invocation. Testing `commands` must correspond exactly and in order to the approved nonempty validation list; Planner/PlanReviewer reject tasks without validation commands. `exit_code` is integer iff run and null iff blocked; status is passed iff 0, failed iff nonzero, blocked iff null; top status is blocked if any blocked, else failed if any failed, else passed. Therefore empty commands can never yield `passed`. + +## Implementation Steps + +> Status Markers: [ ] Open, [/] In Progress, [x] Completed (set after accepted review only!) + +- [ ] **Task 1: Add and configure the lifecycle Orchestrator** + - **Task ID:** T1 + - **Depends On:** None + - **Owned Paths:** `agent-harness/.opencode/agents/Orchestrator.md`, `agent-harness/opencode.jsonc`, `opencode/opencode.jsonc`, `agent-harness/tests/check-background-task.py`, `agent-harness/tests/evidence/background-preflight.json` + - **Shared Resources:** OpenCode agent namespace and Task-depth configuration; root synchronized copies must not be updated manually in this task. + - **Parallel Safe:** No; establish the routing and permission contract before dependent prompt changes. + - **Validation Commands:** `python3 agent-harness/tests/check-background-task.py`; `python3 agent-harness/tests/check-agent-graph.py` + - **Description:** Before any repo edit, perform a shell-only external probe—no missing generated source. Run `command -v opencode`, `opencode --version`, locate installed `packages/opencode/src/tool/task.ts` via the executable's resolved installation root, and use `grep -F` to require `background` and `task_id`; require/export `OPENCODE_EXPERIMENTAL_BACKGROUND_SUBAGENTS=true`. Create a temporary minimal OpenCode config/agent under `mktemp -d` whose prompt invokes one `background: true` Librarian returning `ISSUE101_BACKGROUND_PROBE`; invoke exact installed CLI syntax obtained from `opencode run --help`, wrapped by `python3 -c 'import subprocess,sys; sys.exit(subprocess.run(sys.argv[1:],timeout=60).returncode)' opencode run ...`, capture JSON events, extract child `task_id` and completion token with a short inline Python JSONL reader, and fail if either is absent or completion precedes the parent return expected for background dispatch. EXIT trap aborts extracted child with the version-documented server endpoint if still running, waits for child/server PIDs, copies evidence to `$HOME/.local/state/issue101-background-preflight.json`, and removes temp files. Evidence records all invoked argv, help/version, Task-source path/hash, flag/value, child ID, event sequence/timestamps, timeout/cleanup status. After pass, T1 implements tracked `check-background-task.py` from this proven argv/event contract (not byte identity), reruns it, then edits config. If source/help/API differs, stop and revise PLAN before repository edits. + - **Review Criteria:** External preflight is the first action, uses 60-second timeout/cleanup, produces schema-valid evidence and passes before any edit; failure leaves worktree untouched and blocks fallback; configs have Buddy default, selectable/delegable Orchestrator, disabled built-ins, depth 5, exact permissions. +- [ ] **Task 2: Convert lifecycle roles and define parallel-safe contracts** + - **Task ID:** T2 + - **Depends On:** T1 + - **Owned Paths:** `agent-harness/.opencode/agents/Planner.md`, `agent-harness/.opencode/agents/Builder.md`, `agent-harness/.opencode/agents/Testing.md`, `agent-harness/.opencode/agents/PlanReviewer.md`, `agent-harness/.opencode/agents/CodeReviewer.md`, `agent-harness/.opencode/agents/Committer.md`, `agent-harness/.opencode/agents/Explorer.md`, `agent-harness/.opencode/agents/Buddy.md`, `agent-harness/bin/scoped-commit.py`, `agent-harness/AGENTS.md`, root `AGENTS.md` + - **Shared Resources:** Agent delegation graph and `PLAN.md` state-transition contract. + - **Parallel Safe:** Yes, with T3 after T1 because their owned files are disjoint; coordinate against the same command/agent names. + - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py`; `python3 agent-harness/tests/check-plan-graph.py`; `python3 agent-harness/tests/check-result-contracts.py` + - **Description:** Set Planner/Builder hidden and apply exact Task maps, including DocumentationEngineer deny. Update Planner template and Structured Results. Explorer uses exact snapshots. Add `agent-harness/bin/scoped-commit.py`, invoked as `python3 agent-harness/bin/scoped-commit.py --repo ROOT --task-id ID --message MESSAGE --path PATH [--path PATH...]`. It rejects unknown/duplicate args, invalid Conventional Commit message, absolute/traversal/symlink/glob paths, unowned paths, shell metacharacters, dirty staged index, and expected-set mismatch; uses Python `subprocess.run([...], shell=False, check=True)` for fixed argv `git status --porcelain`, `git diff --cached --name-only`, one `git add -- PATH` per normalized path, `git commit -m MESSAGE`, then verifies empty index and reports peer dirt. Committer denies all Bash except the literal prefix `python3 agent-harness/bin/scoped-commit.py *`, cannot edit, and may not invoke raw Git; prompt requires supplied task ID/message/repeated exact paths. On validation mismatch wrapper exits before staging; on unexpected post-stage failure it exits visibly and preserves state for human recovery. Add unit fixtures for all rejected argv/path/message/index cases and exact successful commit. Reconcile both AGENTS files exclusively in T2. + - **Review Criteria:** Planner/Builder/Testing are hidden; Task maps match; graph/result fixtures pass; Explorer has four Git commands; scoped-commit wrapper tests prove shell-free fixed argv, path/message/index rejection, exact commit paths, peer dirt unstaged, and Committer has no raw Git route; both AGENTS files match finalization semantics. +- [ ] **Task 3: Route and harden lifecycle commands** + - **Task ID:** T3 + - **Depends On:** T1 + - **Owned Paths:** `agent-harness/.opencode/commands/plan.md`, `agent-harness/.opencode/commands/continue_implementation.md`, `agent-harness/.opencode/commands/implement_next_task.md` (deletion), `agent-harness/.opencode/commands/review_plan.md`, `agent-harness/.opencode/commands/review_code.md`, `agent-harness/.opencode/commands/research.md`, `agent-harness/.opencode/commands/archive_plan.md` + - **Shared Resources:** Public command names and Orchestrator routing contract. + - **Parallel Safe:** Yes, with T2 after T1 because the paths are disjoint; command prompts must use the finalized agent/task terminology. + - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py --commands` + - **Description:** Add the currently parent-only `/plan` command to the authoritative harness and assign it to Orchestrator. Replace `/implement_next_task` with `/continue_implementation`; default it to the maximum safe eligible set of up to two tasks, while accepting explicit task IDs and a serial override. Route `/review_plan`, `/review_code`, and `/research` through Orchestrator. Update prompts with the agreed missing/invalid/unapproved/no-work/overwrite/change-scope preconditions and ensure `$ARGUMENTS` narrow rather than silently broaden scope. Change `/research` from “Research into Skill” to durable `docs/research` findings produced directly by Librarian. Review `/archive_plan` for broken agent references but leave its Buddy assignment and behavior unchanged. Ensure command invocation does not bypass Orchestrator by directly selecting Planner, Builder, or reviewers. + - **Review Criteria:** Every lifecycle command except documented `/archive_plan` resolves to Orchestrator; `/continue_implementation` fully replaces the old command; serial/task-ID arguments cannot broaden scope; invalid state fails without retry; `/review_code` cannot perform an unscoped review; `/research` invokes no Builder and creates no skill; `/archive_plan` stays unchanged on Buddy. +- [ ] **Task 4: Persist concurrent research safely within the accepted scope** + - **Task ID:** T4 + - **Depends On:** T1 + - **Owned Paths:** `agent-harness/.opencode/agents/Librarian.md`, `agent-harness/docs/research/.gitkeep`, `agent-harness/docs/research/**` + - **Shared Resources:** `docs/research` namespace and external provider capacity. + - **Parallel Safe:** Yes, with T2 and T3 after T1; no other task owns Librarian or research documentation paths. + - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py --research`; `python3 agent-harness/tests/check-research-scheduling.py` + - **Description:** Create tracked `docs/research/.gitkeep` so the directory exists before dispatch. Permit Librarian reads/writes only under `docs/research/**`; deny source/config/shell/Task. Orchestrator uses read/glob to reject an existing assigned target unless update mode is explicit, rejects symlinked directory/target after Explorer/read inspection, and assigns unique topics/files. Define document metadata, conclusions, sources, uncertainty, and failure/partial status. Directory scope is permission-enforced; assigned-file ownership/collision avoidance is cooperative. Exclude skill creation, verification, shared index, and issue #85. + - **Review Criteria:** Directory exists in a clean checkout; permissions confine writes; source/config/`PLAN.md` are immutable; fixtures cover missing directory, existing target, explicit update, symlink directory/target, duplicate topic/target in one session, and every documented restart status/target combination; no durable reservation is claimed, failures are visible, and no skill/index is created. +- [ ] **Task 5: Synchronize, document, and validate the complete agent graph** + - **Task ID:** T5 + - **Depends On:** T2, T3, T4 + - **Owned Paths:** `agent-harness/README.md`, `agent-harness/tests/**` except T1-owned preflight script/evidence, `agent-harness/tests/runtime-smoke.md`, `agent-harness/tests/runtime-fixture.sh`, `agent-harness/tests/evidence/**` except T1 preflight evidence, synchronized parent `.opencode/**`, root `opencode.jsonc`, root `tui.jsonc`, root `.harness-sync` + - **Shared Resources:** Shared working tree, synchronized harness copy, OpenCode runtime, Git index, and all files changed by T1–T4. + - **Parallel Safe:** No; run only after every prior Builder has terminated and serialize synchronization/validation. + - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py && python3 agent-harness/tests/check-plan-graph.py && python3 agent-harness/tests/check-result-contracts.py && python3 agent-harness/tests/check-research-scheduling.py && python3 agent-harness/tests/check-sync.py`; `cd /Users/mkuckert/env && agent-harness/bin/harness-sync.sh status` + - **Description:** Update README; validate AGENTS. Static scripts own only static assertions. Create exact `runtime-fixture.sh`, `runtime-smoke.md`, and timestamped evidence paths. Each literal setup creates a Git repo with known base commit, approved PLAN, fixture agents that emit named tokens/delays/errors, and expected-state JSON. Each literal assert parses `events.jsonl` and Git state and fails on missing/extra/out-of-order evidence. Required predicates: Planner case has one child ID with `Question.Asked` then `Replied` then completed; two-Builder case has two distinct running intervals overlapping ≥2 seconds, no third child, changes only `area-a/a.txt` and `area-b/b.txt`; overlap has zero Builder child and unchanged HEAD/tree/index; four-research has four overlapping IDs, no fifth, four distinct files, duplicate topic/target zero-child; completion has parent Task return before child completion and later injected completion token with no status-query request; same-ID retry has two attempts sharing ID, fresh continuation has third attempt with different ID only after two errors; every result-negative case emits named validation error and no downstream child; failed batch preserves `area-a/partial.txt`, unchanged HEAD/index, zero Testing/Reviewer/Committer; Testing case records permission approval, exact approved command, exit 1, matching child envelope ID, then Builder correction; scoped commit has empty pre-index, commit diff exactly assigned paths plus PLAN, peer file dirty/unstaged; restart case only checks documented no-guarantee behavior—new session warns, existing target requires update, absent target may dispatch after warning; Buddy case has exactly Buddy→Orchestrator→lifecycle child and no Buddy→Planner/Builder edge. `runtime-smoke.md` contains literal commands/prompts/traps for every named setup/assert pair (no `CASE` metavariable); static success cannot satisfy runtime. Then sync, restart, execute all rows. + - **Review Criteria:** Six static scripts (`check-background-task.py`, `check-agent-graph.py`, `check-plan-graph.py`, `check-result-contracts.py`, `check-research-scheduling.py`, `check-sync.py`) pass assigned assertions; result fixtures explicitly reject empty validation/command arrays, session mismatch, omitted/reordered/extra commands; every named literal runtime assertion passes with evidence at the exact path; both AGENTS files are consistent; tracked sync paths/base meet checks; no rejection/drift/bypass; missing background blocks acceptance. + +## Edge Case & Safety Checklist + +- Empty, missing, malformed, unapproved, already completed, or dependency-blocked `PLAN.md` state fails before implementation dispatch. +- Replacing a non-empty `PLAN.md` requires an explicit user answer; cancellation preserves the existing file. +- Empty task sets and task-ID filters with no match report “no eligible work” without spawning a child. +- Cyclic/unknown dependencies, duplicate task IDs, empty/ambiguous owned paths, overlapping owned paths, shared lockfiles/generated outputs, path aliases, renames, and undeclared global fixtures prevent parallel eligibility; uncertain scope is serialized or rejected, never assumed safe. +- Path/dependency fixtures cover absolute and parent traversal, redundant separators, symlinks/case aliases, literal ancestor overlap, conservative glob overlap, rename old/new paths, duplicate/unknown/self/cyclic dependencies, non-`[x]` prerequisites, conflicting shared resources, and absent/latest-nonapproved review status. +- At most two Builders and four Librarians run concurrently; provider overload or rate limiting is surfaced under the technical-failure retry policy. +- Missing experimental background support is a visible terminal precondition failure for implementation/research, not a silent sequential fallback. +- Foreground Planner questions remain interactive; background agents must not block on required user questions. +- Builder and Testing return their specified single fenced JSON objects; missing, invalid, mismatched, or nonterminal output is a visible technical failure, never inferred success. +- Unknown/duplicate keys, duplicate result blocks, wrong types/nullability, unnormalized or unowned paths, omitted/reordered commands, and inconsistent command exit/status values are rejected by executable contract fixtures. +- Active Builder claims are tracked in the Orchestrator session and retained through resume/fresh-continuation attempts. Already-running peers may finish after a failure, no new work dispatches, retries obey the two-active limit, and any exhausted task aborts review/commit. Cross-session/process claims are not atomic; Explorer's baseline/current Git snapshots detect known foreign/dirty/conflicting changes and the residual limitation is disclosed. +- Orchestrator never edits `PLAN.md` while implementation Builders are active; Builders never edit it during the batch; review/status writes occur only after the all-Builder barrier and are serialized. +- A Builder touches an undeclared path, another agent changes its owned path, or the worktree contains ambiguous pre-existing changes: stop review/commit and report exact paths. +- Validation commands are part of the approved plan. Foreground Testing asks before running them, cannot edit/use Git, reports every exit status, and routes nonzero outcomes through correction without technical retry. +- One Builder fails while peers succeed: wait for all to terminate, apply the failed Builder recovery sequence, then abort all review/commit if recovery is exhausted; preserve every partial change for human inspection. +- Same-session retry uses the returned `task_id`; a fresh Builder continuation receives the original task ID, ownership, dependency state, previous session/error IDs, and instruction to inspect rather than restart or overwrite partial work. +- Reviewer critique and Builder correction remain bounded by the existing three-round circuit breaker and are not confused with Task/API retry attempts. +- Sequential CodeReviewers use explicit task/path/baseline diff scope. Rejection appends critique without approval; correction resumes that Builder, reruns validation and review, and invalidates the old diff; only final acceptance sets `[x]`. Concurrent shared review-log writes and approving unrelated “latest changes” are prohibited. +- Tasks finalize strictly one at a time as review/correction → that task's serialized `PLAN.md` update → scoped commit. Committer begins with an empty index, stages only explicit task-owned paths plus `PLAN.md`, verifies cached-path equality, tolerates only known dirty paths of other successful batch tasks, and visibly aborts on unknown dirty paths, unrelated staged paths, or an indeterminate index. +- Cancellation or process restart may leave modified files and non-durable background state. Treat status as unknown/stale, do not infer success, and require reconciliation before another dispatch. +- Librarian timeout, API error, inaccessible source, invalid source data, contradictory documentation, or partial results are written/reported as such; no fabricated citation or silent fallback is allowed. Assigned-file ownership is cooperative within the permission-enforced `docs/research/**` directory, and pre-existing targets fail unless update mode was explicit. +- Missing `docs/research`, directory/target symlinks, existing targets without update mode, and concurrent duplicate target assignment stop research visibly; the tracked directory and pre-dispatch inspection are required. +- Research topic keys and targets are reserved in the live Orchestrator session before dispatch; duplicate topic or target is rejected. Reservations end with that session, and no durable or cross-process atomic reservation or prior-child recovery is claimed. +- A new Orchestrator session cannot recover prior in-memory research reservations. It warns about this limitation, treats an existing target as requiring update mode, and may dispatch an absent target only after warning; it never claims to know old child status. +- `/archive_plan` remains functionally unchanged on Buddy. Orchestrator may warn against invoking it during active lifecycle work, but issue #101 adds no command precondition; its path/post-mortem mismatch remains out of scope. +- Issue #100 integration-bot behavior and issue #85 research verification are not implemented accidentally through generalized orchestration prompts. + +## Review Log (Plan Review) + +- **Round 1:** Not approved. Addressed 14 blockers: added delegated read-only Git snapshots; completed retry/capacity/claim states; defined rejection, correction, and final approval transitions; made shared-index commits path-exact and task-sequential; specified Builder tools/results and correction resume; separated static checks from runtime guarantees; grounded direct child questions in OpenCode behavior; constrained Buddy and all task chains; documented the archive exception; clarified Librarian's enforced versus cooperative scope; moved synchronized-copy acceptance to T5; added sync conflict handling; split automated and manual validation; and prohibited recursive delegation. +- **Round 2:** Not approved. Addressed five blockers: explicitly changed Explorer's Git permissions; moved validation to a constrained Testing subagent; defined attempted background dispatch rejection as the capability signal; classified scheduler state/claims as cooperative and added exact JSON terminal recognition; and specified setup, fault, observation, evidence, cleanup, and pass/fail for each manual runtime case. +- **Round 3:** Not approved. Integrated the remaining actionable feedback by explaining template migration, specifying Explorer's complete permission contract, defining Testing's cooperative command matching and approval boundary, adding exact Builder/Testing JSON schemas, removing the contradictory archive precondition, defining graph normalization/overlap/cycle/approval algorithms, and requiring executable runtime fixtures/matrix rows without placeholders. The reviewer also objected to task metadata beyond the example template; this plan retains it because T2 explicitly updates the authoritative Planner template and every mandatory section/field remains present. Maximum three review rounds reached; no further automated review is permitted. +- **Additional review A (user-authorized):** Not approved. Integrated Round-4 findings: exact result schemas, deny-by-default graph, built-in bypass prevention, AGENTS ownership, complete sync checks, background feasibility gate, Committer sequence, executable validation, and research directory handling. +- **Additional review B (user-authorized):** Not approved. Integrated explicit DocumentationEngineer/system-agent treatment; Buddy-only Orchestrator targeting; Testing session identity; exclusive dual-AGENTS ownership; `tui.jsonc`/transactional sync; external pre-edit background probe; deterministic graph/path/research normalization and stale reservations; strict Committer grammar; static/runtime separation; concrete runtime rows; and removal of the non-template Round 4 field. +- **Additional review C (user-authorized):** Not approved. Added nonempty Validation Commands to every task; specified the external background probe invocation, flag, timeout, abort/wait/trap cleanup, and evidence schema; defined a literal runtime fixture helper/command pattern and exact event/Git assertions per case; replaced contradictory session-only research retention with a durable reservation ledger and deterministic stale reconciliation; and required Testing session-envelope equality plus nonempty ordered validation. +- **Additional review D (user-authorized):** Not approved. Assigned the background checker/evidence to T1 and specified external probe invocation/API inspection/timeout/abort/wait/copy cleanup; replaced runtime `CASE` placeholders with literal named helper subcommands, paths, prompts, and assertions; rejected misleading non-atomic durable research state in favor of explicit post-restart child-status/target reconciliation; and added negative result fixtures for empty lists, session mismatch, and omitted/reordered/extra commands. +- **Additional review E (user-authorized):** Not approved.

Preserve Buddy as the default general-purpose primary agent, route lifecycle commands through Orchestrator, support bounded prompt-coordinated parallel Builders and Librarians, and keep issue #100's GitHub bot behavior outside this issue. +Add an OpenCode lifecycle Orchestrator that invokes Planner and Builder as subagents, preserves the existing phase-based workflow, routes lifecycle commands through one coordinator, and supports bounded cooperative parallelism without introducing a custom scheduler, lock service, Git-worktree manager, probe suite, or runtime framework. ## Requirements & Decisions -- **Frameworks:** Use the existing OpenCode Markdown agent/command framework, foreground and experimental background Task delegation, Task session continuation through `task_id`, path-scoped permissions, the repository's Planner/PlanReviewer and Builder/Testing/CodeReviewer/Committer loops, and `agent-harness/bin/harness-sync.sh`. The authoritative harness is `agent-harness/`; `.opencode/` and root `opencode.jsonc` are synchronized project copies, while `opencode/opencode.jsonc` is maintained separately. OpenCode—not agent prompts—supplies foreground waiting, child sessions, `task_id` continuation, background jobs, and completion events. Restart OpenCode after configuration synchronization and before discovery/runtime checks. -- **Chosen Libraries:** None. OpenCode already supplies agent modes, Task delegation, child session IDs, background execution, permissions, and depth controls. Prompt-coordinated shared-worktree scheduling was explicitly chosen over Git worktrees or a SQLite claim ledger because worktrees would require expanding the Nono sandbox. This is a cooperative coordination mechanism, not an atomic filesystem safety boundary. -- **Error Handling Strategy:** Follow “fail loud, never fake.” Orchestrator preserves the child error and reports phase, task/topic, session ID when available, and attempt count. A technical failure is Task state `error`/`cancelled`, timeout/API/tool error, unavailable session, step-limit termination without the required result, or a terminal result whose single fenced JSON object is missing, invalid, nonterminal, mismatched to the assigned ID, lacks required keys, or reports unaccounted paths. Each child follows the cooperative prompt protocol `queued → running → resume-running → continuation-running (Builder only) → succeeded | exhausted`; Orchestrator records state, session ID, claim, baseline, attempt, and result in its session context. On initial technical failure, retain claims and resume that `task_id` once. A still-failing Builder gets one fresh continuation session instructed to inspect and continue partial work; any other child becomes exhausted. Already-running peers may finish, no new batch task dispatches after a failure, and retry/correction Builders count toward the two-active limit. Review starts only when every batch task succeeded; any exhausted task aborts the batch without testing, review, or commit and leaves changes visible. Normal review critique, Testing nonzero exit, user rejection, and deterministic precondition failures are correction/precondition outcomes, not technical retries. If a call with `background: true` is rejected because the parameter/capability is unavailable—unknown argument/schema error or an explicit disabled-background error—treat it as a non-retryable missing-core-feature precondition, disclose it, and stop rather than run serially. Prompts cannot inspect the process environment before this attempt. Scheduling, limits, claims, barriers, result interpretation, and retries are cooperative session-local protocol—not plugin-enforced, transactional, durable, or safe across independent sessions—and documentation/acceptance must not claim otherwise. -- **Scope Boundary:** Implement the orchestration architecture requested by issue #101 only. Do not implement issue #100's GitHub issue polling, bot-comment detection, research-comment publication, or integration-bot behavior. Leave `/archive_plan` assigned to Buddy and functionally unchanged; its pre-existing archive-path, ownership, and post-mortem inconsistencies are out of scope. -- **Primary-Agent Decision:** Buddy remains the general-purpose primary agent and is explicitly selected through OpenCode's `default_agent` setting. Orchestrator uses `mode: all` so it is selectable and callable by Buddy/commands. Buddy's Task allowlist is exactly Orchestrator, Explorer, and Librarian; lifecycle intent must pass through Orchestrator. Buddy asks one question when routing is ambiguous and refuses a lifecycle bypass. -- **Question Flow:** Planner runs as a foreground Task child with `question: allow`. Current OpenCode Task/Question services associate the pending question with the child session, render it in the shared UI, keep the parent waiting, and resume the child after reply. Runtime-smoke this source-verified behavior; if the installed version does not render it, stop as incompatible rather than invent a relay. Never run interactive planning in the background. -- **Delegation Permissions:** Every harness agent uses deny-by-default Task mappings. Buddy denies `*` and allows only `Orchestrator`, `Explorer`, and `Librarian`; Buddy is the sole agent allowed to target Orchestrator. Orchestrator denies `*` and allows only `Planner`, `Builder`, `Testing`, `PlanReviewer`, `CodeReviewer`, `Explorer`, and `Librarian`, but cannot target itself. Planner denies `*` and allows only Explorer, Librarian, PlanReviewer. Builder denies `*` and allows only Committer. PlanReviewer and CodeReviewer deny `*` and allow only Explorer/Librarian. Explorer, Librarian, Testing, Committer, and DocumentationEngineer deny Task entirely. Any other installed/system agent is outside the harness graph and must not be referenced by harness prompts; project config disables built-in `plan`, `build`, `general`, and `explore` to prevent bypass. -- **Task Graph:** `PLAN.md` is canonical. IDs match `[A-Z][A-Z0-9_-]*` and are unique; dependencies are `None` or existing IDs. Resolve repository root with `git rev-parse --show-toplevel`; reject absolute paths, empty paths, NUL/newline, `.`/`..` segments, unresolved paths outside the root, symlinks at any existing component, and case-fold collisions. Normalize `/`, duplicate separators, and trailing `/`. Literal scopes overlap on equality/ancestor relation. Glob scopes permit only `*`, `?`, and `**`; compute fixed literal prefixes and treat equal/ancestor prefixes or any indeterminate intersection as conflict. Renames require ownership of both old/new paths. Shared-resource names conflict on equality or `/` ancestor relation. Diagnose duplicate/unknown/self dependencies, then detect cycles by deterministic ID-sorted DFS; a task is dependency-ready only when every prerequisite is `[x]`. Parallel dispatch requires `[ ]`, `Parallel Safe: Yes`, ready dependencies, and pairwise nonoverlap. Approval means the latest populated Plan Review entry is exactly `Approved`. `check-plan-graph.py` implements this same algorithm; Orchestrator may add metadata but never while Builders run. -- **Implementation Scheduling:** `/continue_implementation` replaces `/implement_next_task`. It selects at most two approved, dependency-ready, explicitly parallel-safe tasks with disjoint normalized repository-relative owned paths/shared resources; arguments may narrow IDs or force serial execution. Orchestrator tracks cooperative claims in-session. Before dispatch and each review, it invokes Explorer in foreground to capture baseline/current commit and dirty/staged paths through exactly `git rev-parse HEAD`, `git status --porcelain`, `git diff --name-only`, and `git diff --cached --name-only`. It compares snapshots with declared ownership and known batch outputs and stops on overlap, unknown dirty/staged path, alias/symlink, or indeterminate state. Snapshots and prompts do not atomically protect against another process, disobedient agent, or undeclared/generated files. -- **Batch Barrier:** Background Builders implement only assigned scope and do not edit `PLAN.md`, test, review, or commit. Orchestrator waits for all Builders and applies the retry protocol while retaining claims. If all succeed, finalize one task at a time: Explorer confirms paths and empty index; Orchestrator changes only that task to `[/]`; foreground Testing runs approved validation; CodeReviewer receives task ID, baseline, exact diff/scope, and test result. Testing failure or review rejection appends critique only and never sets `[x]`; Orchestrator resumes the corresponding successful Builder session with exact feedback, then repeats snapshot, Testing, and review. Each task has at most three validation/review rounds, independent of technical retries. Only accepted review sets `[x]`. The same Builder then invokes Committer with owned paths plus that task's serialized `PLAN.md` change. Committer tolerates known dirty peer-task paths but requires an initially empty index, stages only its allowlist plus `PLAN.md`, verifies cached paths exactly, and aborts on unknown dirt or out-of-scope staged paths. Record baseline/resulting paths, then finalize the next task. If any Builder exhausts recovery, no batch task is tested, reviewed, or committed. -- **Research Scheduling:** `/research` routes to at most four background Librarians. Resolve the Git root, Unicode-normalize topic/target to NFC, case-fold only for collision keys, convert separators to `/`, collapse duplicates, and reject absolute paths, NUL/newline, empty/`.`/`..` segments, non-`.md` targets, targets outside `docs/research/`, symlinks in every existing component, a non-directory parent, or a case-fold collision. Nonexistent final files are allowed only when all parents exist as real directories. Within one live Orchestrator session, sort requests by `(topic-key,target-key)`, reserve all keys in memory before dispatch, and reject duplicate topic or target. Reservations intentionally end with that Orchestrator session and provide no restart/cross-process guarantee. A new session performs only filesystem collision checks: existing target requires explicit update mode; absent target may dispatch after warning that another process cannot be detected. Do not infer old child status/topic/target from OpenCode session metadata and do not claim restart reconciliation. Verification belongs to issue #85. -- **Command Preconditions:** `/plan` asks before replacing a non-empty `PLAN.md`. `/continue_implementation` stops when `PLAN.md` is missing, structurally invalid, unapproved, has no open dependency-ready task matching the request, or conflicts with an active claim. `/review_plan` stops without a plan. `/review_code` stops without both a plan and an identifiable task/change scope; it no longer performs an unscoped general review. These deterministic failures are reported without retry. -- **Structured Result Parsing:** Builder and Testing emit exactly one final fenced `json` block. Reject duplicate blocks/keys, unknown keys, wrong types/nulls, invalid status/path/ID/session, command mismatch, and unowned paths. Builder schema is exactly `{task_id: string, status: "succeeded"|"failed", baseline: 40- or 64-lowercase-hex Git ID, modified_paths: unique array, validation_requested: unique array, concerns: array, session_id: nonempty string}`. Testing schema is exactly `{task_id: string, status: "passed"|"failed"|"blocked", commands: ordered array<{command: string, exit_code: integer|null, status: "passed"|"failed"|"blocked", summary: string}>, concerns: array, session_id: nonempty string}`. Each result `session_id` must equal the current Task envelope's child-session ID, including every resumed invocation. Testing `commands` must correspond exactly and in order to the approved nonempty validation list; Planner/PlanReviewer reject tasks without validation commands. `exit_code` is integer iff run and null iff blocked; status is passed iff 0, failed iff nonzero, blocked iff null; top status is blocked if any blocked, else failed if any failed, else passed. Therefore empty commands can never yield `passed`. +- **Frameworks:** Use the existing OpenCode Markdown agents and commands, native foreground/background Task delegation, `task_id` continuation, agent permissions, existing review agents, and `agent-harness/bin/harness-sync.sh`. `agent-harness/` remains authoritative; synchronized parent copies are updated through the existing sync mechanism. Set `subagent_depth` to `5` in `agent-harness/opencode.jsonc` and the separate `opencode/opencode.jsonc` runtime configuration. +- **Chosen Libraries:** None. OpenCode-native delegation is sufficient. Prompt-coordinated shared-worktree execution is an explicit user decision; no new orchestration library, SQLite ledger, custom scheduler, atomic claim service, Git worktree isolation, scoped-commit wrapper, or background compatibility probe is part of issue #101. +- **Error Handling Strategy:** Fail loudly and preserve the child error, phase, task/topic, session ID when available, and attempt count. On a technical Task failure (timeout, API/tool error, step-limit/incomplete result, unavailable session), resume the same child session exactly once. If a Builder still fails, launch one fresh Builder session with the original task scope and instructions to inspect and continue partial work; if it also fails or stops, halt the implementation batch and report briefly. Other subagents stop after the failed resume. Review critique, test failure, user rejection, and invalid workflow state are not technical Task failures and do not trigger this retry sequence. If background Task execution is unavailable, disclose that the required harness feature is missing and stop; do not silently fall back to serial execution. +- **Scope Boundary:** Issue #101 establishes the lifecycle agent architecture. It does not implement issue #100's GitHub bot, issue #85's research-verification workflow, durable cross-session scheduling, atomic filesystem locks, transactional rollback, or archive-command cleanup. `/archive_plan` remains assigned to Buddy and functionally unchanged. +- **Primary Agents:** Buddy remains the default general-purpose primary agent. Orchestrator uses the OpenCode mode that makes it user-selectable and Task-delegable. Planner and Builder become hidden subagents. Buddy delegates lifecycle requests to Orchestrator and retains general assistance for unrelated work. +- **Planner Questions:** Planner remains allowed to use `question` while running as a foreground Task. Orchestrator waits while the child question is presented to the user. Interactive planning is never dispatched in the background. +- **Delegation Graph:** Use deny-by-default Task target rules. Buddy may invoke Orchestrator, Explorer, and Librarian. Orchestrator may invoke Planner, Builder, Testing, PlanReviewer, CodeReviewer, Explorer, and Librarian, but not Committer. Planner may invoke Explorer, Librarian, and PlanReviewer. Builder may invoke Committer only during Orchestrator-authorized finalization. PlanReviewer and CodeReviewer may invoke Explorer and Librarian. Explorer, Librarian, Testing, and Committer are leaves. Built-in `plan`, `build`, `general`, and `explore` remain disabled in harness project configuration so lifecycle work cannot bypass Orchestrator. +- **Plan Dependency Graph:** Extend Planner's mandatory task format with `Task ID`, `Depends On`, `Owned Paths`, `Shared Resources`, `Parallel Safe`, and `Validation Commands`, in addition to `Description` and `Review Criteria`. IDs must be unique; dependencies must reference known tasks and be acyclic; dependency-ready means all prerequisites are `[x]`. Paths must be repository-relative and explicit enough to compare. PlanReviewer rejects ambiguous ownership, undeclared shared files/resources, unsafe validation commands, and parallel-safe tasks with apparent overlap. `PLAN.md` is the durable graph; Orchestrator may clarify its scheduling metadata only while no Builder is active. +- **Cooperative Parallelism:** `/continue_implementation` replaces `/implement_next_task`. It may launch at most two dependency-ready Builders whose approved tasks are explicitly parallel-safe and have disjoint declared paths/resources. The Orchestrator encourages parallelism only when this is clear; otherwise it runs one task or asks. Claims, overlap avoidance, and the two-agent limit are prompt/session coordinated—not atomic or safe across independent OpenCode processes. Builders must stop and report if they discover undeclared overlap or unrelated concurrent changes. Multiple Librarians may run in parallel up to four when assigned distinct topics/files. +- **Implementation Batch Barrier:** Active Builders modify only their assigned task scope and do not edit `PLAN.md`, invoke review, or commit. Orchestrator waits for all Builders in the selected batch. If one exhausts recovery, no task in that batch proceeds to review/commit. If all succeed, Orchestrator finalizes tasks one at a time: run approved validation through Testing, invoke task-scoped CodeReviewer, return critique to the corresponding Builder, and repeat for at most three review/correction rounds. Only accepted review changes that task to `[x]`; Builder then invokes Committer for that task. This sequencing reduces shared `PLAN.md` and Git-index races but does not make the shared worktree transactional. +- **Research:** `/research` routes directly from Orchestrator to Librarian rather than Builder. Librarian may write only under `docs/research/**` and writes durable research notes, not `SKILL.md`. Orchestrator assigns distinct topic/file scopes and checks for an existing target before dispatch. Research verification remains issue #85. Parallel topic/file reservations are session-local and cooperative; no restart guarantee is claimed. +- **Command Preconditions:** `/plan` asks before replacing a nonempty `PLAN.md`. `/continue_implementation` stops for a missing, malformed, unapproved, completed, dependency-blocked, or scope-conflicting plan. `/review_plan` requires a plan. `/review_code` requires a plan plus an identifiable task/change scope and no longer performs a vague general review. Deterministic precondition failures are reported without retry. ## Implementation Steps > Status Markers: [ ] Open, [/] In Progress, [x] Completed (set after accepted review only!) -- [ ] **Task 1: Add and configure the lifecycle Orchestrator** - - **Task ID:** T1 - - **Depends On:** None - - **Owned Paths:** `agent-harness/.opencode/agents/Orchestrator.md`, `agent-harness/opencode.jsonc`, `opencode/opencode.jsonc`, `agent-harness/tests/check-background-task.py`, `agent-harness/tests/evidence/background-preflight.json` - - **Shared Resources:** OpenCode agent namespace and Task-depth configuration; root synchronized copies must not be updated manually in this task. - - **Parallel Safe:** No; establish the routing and permission contract before dependent prompt changes. - - **Validation Commands:** `python3 agent-harness/tests/check-background-task.py`; `python3 agent-harness/tests/check-agent-graph.py` - - **Description:** Before any repo edit, perform a shell-only external probe—no missing generated source. Run `command -v opencode`, `opencode --version`, locate installed `packages/opencode/src/tool/task.ts` via the executable's resolved installation root, and use `grep -F` to require `background` and `task_id`; require/export `OPENCODE_EXPERIMENTAL_BACKGROUND_SUBAGENTS=true`. Create a temporary minimal OpenCode config/agent under `mktemp -d` whose prompt invokes one `background: true` Librarian returning `ISSUE101_BACKGROUND_PROBE`; invoke exact installed CLI syntax obtained from `opencode run --help`, wrapped by `python3 -c 'import subprocess,sys; sys.exit(subprocess.run(sys.argv[1:],timeout=60).returncode)' opencode run ...`, capture JSON events, extract child `task_id` and completion token with a short inline Python JSONL reader, and fail if either is absent or completion precedes the parent return expected for background dispatch. EXIT trap aborts extracted child with the version-documented server endpoint if still running, waits for child/server PIDs, copies evidence to `$HOME/.local/state/issue101-background-preflight.json`, and removes temp files. Evidence records all invoked argv, help/version, Task-source path/hash, flag/value, child ID, event sequence/timestamps, timeout/cleanup status. After pass, T1 implements tracked `check-background-task.py` from this proven argv/event contract (not byte identity), reruns it, then edits config. If source/help/API differs, stop and revise PLAN before repository edits. - - **Review Criteria:** External preflight is the first action, uses 60-second timeout/cleanup, produces schema-valid evidence and passes before any edit; failure leaves worktree untouched and blocks fallback; configs have Buddy default, selectable/delegable Orchestrator, disabled built-ins, depth 5, exact permissions. -- [ ] **Task 2: Convert lifecycle roles and define parallel-safe contracts** - - **Task ID:** T2 - - **Depends On:** T1 - - **Owned Paths:** `agent-harness/.opencode/agents/Planner.md`, `agent-harness/.opencode/agents/Builder.md`, `agent-harness/.opencode/agents/Testing.md`, `agent-harness/.opencode/agents/PlanReviewer.md`, `agent-harness/.opencode/agents/CodeReviewer.md`, `agent-harness/.opencode/agents/Committer.md`, `agent-harness/.opencode/agents/Explorer.md`, `agent-harness/.opencode/agents/Buddy.md`, `agent-harness/bin/scoped-commit.py`, `agent-harness/AGENTS.md`, root `AGENTS.md` - - **Shared Resources:** Agent delegation graph and `PLAN.md` state-transition contract. - - **Parallel Safe:** Yes, with T3 after T1 because their owned files are disjoint; coordinate against the same command/agent names. - - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py`; `python3 agent-harness/tests/check-plan-graph.py`; `python3 agent-harness/tests/check-result-contracts.py` - - **Description:** Set Planner/Builder hidden and apply exact Task maps, including DocumentationEngineer deny. Update Planner template and Structured Results. Explorer uses exact snapshots. Add `agent-harness/bin/scoped-commit.py`, invoked as `python3 agent-harness/bin/scoped-commit.py --repo ROOT --task-id ID --message MESSAGE --path PATH [--path PATH...]`. It rejects unknown/duplicate args, invalid Conventional Commit message, absolute/traversal/symlink/glob paths, unowned paths, shell metacharacters, dirty staged index, and expected-set mismatch; uses Python `subprocess.run([...], shell=False, check=True)` for fixed argv `git status --porcelain`, `git diff --cached --name-only`, one `git add -- PATH` per normalized path, `git commit -m MESSAGE`, then verifies empty index and reports peer dirt. Committer denies all Bash except the literal prefix `python3 agent-harness/bin/scoped-commit.py *`, cannot edit, and may not invoke raw Git; prompt requires supplied task ID/message/repeated exact paths. On validation mismatch wrapper exits before staging; on unexpected post-stage failure it exits visibly and preserves state for human recovery. Add unit fixtures for all rejected argv/path/message/index cases and exact successful commit. Reconcile both AGENTS files exclusively in T2. - - **Review Criteria:** Planner/Builder/Testing are hidden; Task maps match; graph/result fixtures pass; Explorer has four Git commands; scoped-commit wrapper tests prove shell-free fixed argv, path/message/index rejection, exact commit paths, peer dirt unstaged, and Committer has no raw Git route; both AGENTS files match finalization semantics. -- [ ] **Task 3: Route and harden lifecycle commands** - - **Task ID:** T3 - - **Depends On:** T1 - - **Owned Paths:** `agent-harness/.opencode/commands/plan.md`, `agent-harness/.opencode/commands/continue_implementation.md`, `agent-harness/.opencode/commands/implement_next_task.md` (deletion), `agent-harness/.opencode/commands/review_plan.md`, `agent-harness/.opencode/commands/review_code.md`, `agent-harness/.opencode/commands/research.md`, `agent-harness/.opencode/commands/archive_plan.md` - - **Shared Resources:** Public command names and Orchestrator routing contract. - - **Parallel Safe:** Yes, with T2 after T1 because the paths are disjoint; command prompts must use the finalized agent/task terminology. - - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py --commands` - - **Description:** Add the currently parent-only `/plan` command to the authoritative harness and assign it to Orchestrator. Replace `/implement_next_task` with `/continue_implementation`; default it to the maximum safe eligible set of up to two tasks, while accepting explicit task IDs and a serial override. Route `/review_plan`, `/review_code`, and `/research` through Orchestrator. Update prompts with the agreed missing/invalid/unapproved/no-work/overwrite/change-scope preconditions and ensure `$ARGUMENTS` narrow rather than silently broaden scope. Change `/research` from “Research into Skill” to durable `docs/research` findings produced directly by Librarian. Review `/archive_plan` for broken agent references but leave its Buddy assignment and behavior unchanged. Ensure command invocation does not bypass Orchestrator by directly selecting Planner, Builder, or reviewers. - - **Review Criteria:** Every lifecycle command except documented `/archive_plan` resolves to Orchestrator; `/continue_implementation` fully replaces the old command; serial/task-ID arguments cannot broaden scope; invalid state fails without retry; `/review_code` cannot perform an unscoped review; `/research` invokes no Builder and creates no skill; `/archive_plan` stays unchanged on Buddy. -- [ ] **Task 4: Persist concurrent research safely within the accepted scope** - - **Task ID:** T4 - - **Depends On:** T1 - - **Owned Paths:** `agent-harness/.opencode/agents/Librarian.md`, `agent-harness/docs/research/.gitkeep`, `agent-harness/docs/research/**` - - **Shared Resources:** `docs/research` namespace and external provider capacity. - - **Parallel Safe:** Yes, with T2 and T3 after T1; no other task owns Librarian or research documentation paths. - - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py --research`; `python3 agent-harness/tests/check-research-scheduling.py` - - **Description:** Create tracked `docs/research/.gitkeep` so the directory exists before dispatch. Permit Librarian reads/writes only under `docs/research/**`; deny source/config/shell/Task. Orchestrator uses read/glob to reject an existing assigned target unless update mode is explicit, rejects symlinked directory/target after Explorer/read inspection, and assigns unique topics/files. Define document metadata, conclusions, sources, uncertainty, and failure/partial status. Directory scope is permission-enforced; assigned-file ownership/collision avoidance is cooperative. Exclude skill creation, verification, shared index, and issue #85. - - **Review Criteria:** Directory exists in a clean checkout; permissions confine writes; source/config/`PLAN.md` are immutable; fixtures cover missing directory, existing target, explicit update, symlink directory/target, duplicate topic/target in one session, and every documented restart status/target combination; no durable reservation is claimed, failures are visible, and no skill/index is created. -- [ ] **Task 5: Synchronize, document, and validate the complete agent graph** - - **Task ID:** T5 - - **Depends On:** T2, T3, T4 - - **Owned Paths:** `agent-harness/README.md`, `agent-harness/tests/**` except T1-owned preflight script/evidence, `agent-harness/tests/runtime-smoke.md`, `agent-harness/tests/runtime-fixture.sh`, `agent-harness/tests/evidence/**` except T1 preflight evidence, synchronized parent `.opencode/**`, root `opencode.jsonc`, root `tui.jsonc`, root `.harness-sync` - - **Shared Resources:** Shared working tree, synchronized harness copy, OpenCode runtime, Git index, and all files changed by T1–T4. - - **Parallel Safe:** No; run only after every prior Builder has terminated and serialize synchronization/validation. - - **Validation Commands:** `python3 agent-harness/tests/check-agent-graph.py && python3 agent-harness/tests/check-plan-graph.py && python3 agent-harness/tests/check-result-contracts.py && python3 agent-harness/tests/check-research-scheduling.py && python3 agent-harness/tests/check-sync.py`; `cd /Users/mkuckert/env && agent-harness/bin/harness-sync.sh status` - - **Description:** Update README; validate AGENTS. Static scripts own only static assertions. Create exact `runtime-fixture.sh`, `runtime-smoke.md`, and timestamped evidence paths. Each literal setup creates a Git repo with known base commit, approved PLAN, fixture agents that emit named tokens/delays/errors, and expected-state JSON. Each literal assert parses `events.jsonl` and Git state and fails on missing/extra/out-of-order evidence. Required predicates: Planner case has one child ID with `Question.Asked` then `Replied` then completed; two-Builder case has two distinct running intervals overlapping ≥2 seconds, no third child, changes only `area-a/a.txt` and `area-b/b.txt`; overlap has zero Builder child and unchanged HEAD/tree/index; four-research has four overlapping IDs, no fifth, four distinct files, duplicate topic/target zero-child; completion has parent Task return before child completion and later injected completion token with no status-query request; same-ID retry has two attempts sharing ID, fresh continuation has third attempt with different ID only after two errors; every result-negative case emits named validation error and no downstream child; failed batch preserves `area-a/partial.txt`, unchanged HEAD/index, zero Testing/Reviewer/Committer; Testing case records permission approval, exact approved command, exit 1, matching child envelope ID, then Builder correction; scoped commit has empty pre-index, commit diff exactly assigned paths plus PLAN, peer file dirty/unstaged; restart case only checks documented no-guarantee behavior—new session warns, existing target requires update, absent target may dispatch after warning; Buddy case has exactly Buddy→Orchestrator→lifecycle child and no Buddy→Planner/Builder edge. `runtime-smoke.md` contains literal commands/prompts/traps for every named setup/assert pair (no `CASE` metavariable); static success cannot satisfy runtime. Then sync, restart, execute all rows. - - **Review Criteria:** Six static scripts (`check-background-task.py`, `check-agent-graph.py`, `check-plan-graph.py`, `check-result-contracts.py`, `check-research-scheduling.py`, `check-sync.py`) pass assigned assertions; result fixtures explicitly reject empty validation/command arrays, session mismatch, omitted/reordered/extra commands; every named literal runtime assertion passes with evidence at the exact path; both AGENTS files are consistent; tracked sync paths/base meet checks; no rejection/drift/bypass; missing background blocks acceptance. +- [ ] **Task 1: Introduce the Orchestrator and update agent modes** + - **Description:** Add `agent-harness/.opencode/agents/Orchestrator.md` as a selectable/delegable lifecycle coordinator. Encode phase routing, foreground Planner interaction, cooperative concurrency limits, batch barriers, retry policy, and fail-loud preconditions. Convert Planner and Builder from primary to hidden subagents. Keep Buddy as the configured default and teach it to delegate lifecycle intent. Apply explicit deny-by-default Task target mappings to Buddy, Orchestrator, Planner, Builder, PlanReviewer, CodeReviewer, Explorer, Librarian, Testing, and Committer. Preserve built-in agent disablement and set `subagent_depth` to `5` in `agent-harness/opencode.jsonc` and `opencode/opencode.jsonc`. + - **Review Criteria:** Buddy is the effective default; Orchestrator is selectable and Task-delegable; Planner and Builder are hidden subagents; only documented delegation edges are allowed; no recursive Orchestrator edge or direct Orchestrator-to-Committer edge exists; built-in lifecycle agents remain disabled; both depth settings are `5`; Planner retains direct foreground question access. +- [ ] **Task 2: Define planning, implementation, review, and commit contracts** + - **Description:** Update Planner's template with task IDs, dependencies, owned paths, shared resources, parallel-safety, and validation commands. Update PlanReviewer to reject missing/invalid dependencies, cycles, unsafe or ambiguous ownership, and apparent overlap among parallel tasks. Change Builder from selecting “the first open task” to implementing only the Orchestrator-supplied task ID/scope; it must not edit `PLAN.md`, review, or commit during an active batch and must report modified paths, validation requested, and concerns. Make Testing a hidden non-editing subagent that runs only plan-approved validation with user approval where required. Make CodeReviewer task/scope-specific, with critique leaving the task incomplete and acceptance alone setting `[x]`. Update Committer to stage only the task paths explicitly supplied by Builder plus the serialized `PLAN.md` change and to fail visibly if unrelated staged changes make scope unclear. Reconcile root and `agent-harness/AGENTS.md` so the Orchestrator batch workflow supersedes direct per-unit commits for harness lifecycle work. + - **Review Criteria:** New plans contain enough dependency/scope data for scheduling; PlanReviewer rejects obvious graph/overlap errors; Builder cannot autonomously choose another task or mutate plan state during implementation; Testing cannot edit source or use Git; CodeReviewer reviews one identified task and controls `[x]`; Committer is instructed to avoid broad staging and aborts on ambiguous index state; both AGENTS files describe the same lifecycle flow. +- [ ] **Task 3: Route and rename lifecycle commands** + - **Description:** Add the parent-only `/plan` command to the authoritative harness and route it through Orchestrator. Replace `/implement_next_task` with `/continue_implementation`; support optional task IDs or a serial request while defaulting to the maximum safe eligible set of at most two tasks. Route `/review_plan`, `/review_code`, and `/research` through Orchestrator. Preserve `$ARGUMENTS` as a scope-narrowing input. Change `/research` from skill generation to durable research notes. Keep `/archive_plan` as the documented Buddy-owned exception. + - **Review Criteria:** All lifecycle commands except `/archive_plan` target Orchestrator; the old implementation command is removed; `/continue_implementation` cannot exceed two Builders and does not broaden an explicit task/serial request; invalid states fail before child dispatch; `/review_code` cannot perform an unscoped review; `/research` does not invoke Builder or create a skill; `/archive_plan` remains unchanged. +- [ ] **Task 4: Enable durable Librarian research notes** + - **Description:** Update Librarian permissions to allow writes only under `agent-harness/docs/research/**`, create that directory in the authoritative harness, and define a note format containing topic, date, scope, conclusions, source URLs/version context, uncertainty, and partial/failure status. Orchestrator assigns distinct normalized filenames, rejects an existing target unless update was explicitly requested, and dispatches at most four distinct topics. Do not implement verification, a shared index, skills, or durable scheduling metadata. + - **Review Criteria:** Librarian cannot modify source, configuration, `PLAN.md`, or files outside `docs/research/**`; concurrent requests use distinct topic/file scopes; existing targets require explicit update intent; API/source failures and partial findings are visible; no `SKILL.md`, verification workflow, or scheduling ledger is introduced. +- [ ] **Task 5: Synchronize, document, and validate the streamlined architecture** + - **Description:** Update `agent-harness/README.md` with the agent graph, command mapping, question flow, retry rules, cooperative parallel limits, batch finalization, research location, and explicit non-atomic/cross-session limitations. Add lightweight dependency-free static checks for agent modes, Task target mappings, built-in disablement, depth/default configuration, command routing/removal, required plan task fields, and Librarian write confinement. Add a concise manual smoke checklist for: Planner question flow; one and two Builder execution; overlap rejection; missing background support; same-session retry and Builder fresh continuation; failed-batch no-review/no-commit; validation/review correction; scoped sequential commits; up to four distinct Librarians; and Buddy natural-language delegation. Use `harness-sync.sh` to propagate authoritative `.opencode` and config changes to the parent project, stop visibly on conflict/cancellation, check for rejected patches, and confirm final sync status has no unintended drift. Validate the separately maintained `opencode/opencode.jsonc` and restart OpenCode before manual smoke checks. + - **Review Criteria:** Static checks pass without new libraries; manual smoke results are recorded as pass/fail with brief evidence; OpenCode loads all changed config/frontmatter; expected primary/subagent modes and command targets are discoverable; parent and authoritative synchronized paths agree without rejected patches or unintended drift; depth is `5` in both intended configs; documentation clearly distinguishes cooperative prompt coordination from enforced isolation. ## Edge Case & Safety Checklist -- Empty, missing, malformed, unapproved, already completed, or dependency-blocked `PLAN.md` state fails before implementation dispatch. -- Replacing a non-empty `PLAN.md` requires an explicit user answer; cancellation preserves the existing file. -- Empty task sets and task-ID filters with no match report “no eligible work” without spawning a child. -- Cyclic/unknown dependencies, duplicate task IDs, empty/ambiguous owned paths, overlapping owned paths, shared lockfiles/generated outputs, path aliases, renames, and undeclared global fixtures prevent parallel eligibility; uncertain scope is serialized or rejected, never assumed safe. -- Path/dependency fixtures cover absolute and parent traversal, redundant separators, symlinks/case aliases, literal ancestor overlap, conservative glob overlap, rename old/new paths, duplicate/unknown/self/cyclic dependencies, non-`[x]` prerequisites, conflicting shared resources, and absent/latest-nonapproved review status. -- At most two Builders and four Librarians run concurrently; provider overload or rate limiting is surfaced under the technical-failure retry policy. -- Missing experimental background support is a visible terminal precondition failure for implementation/research, not a silent sequential fallback. -- Foreground Planner questions remain interactive; background agents must not block on required user questions. -- Builder and Testing return their specified single fenced JSON objects; missing, invalid, mismatched, or nonterminal output is a visible technical failure, never inferred success. -- Unknown/duplicate keys, duplicate result blocks, wrong types/nullability, unnormalized or unowned paths, omitted/reordered commands, and inconsistent command exit/status values are rejected by executable contract fixtures. -- Active Builder claims are tracked in the Orchestrator session and retained through resume/fresh-continuation attempts. Already-running peers may finish after a failure, no new work dispatches, retries obey the two-active limit, and any exhausted task aborts review/commit. Cross-session/process claims are not atomic; Explorer's baseline/current Git snapshots detect known foreign/dirty/conflicting changes and the residual limitation is disclosed. -- Orchestrator never edits `PLAN.md` while implementation Builders are active; Builders never edit it during the batch; review/status writes occur only after the all-Builder barrier and are serialized. -- A Builder touches an undeclared path, another agent changes its owned path, or the worktree contains ambiguous pre-existing changes: stop review/commit and report exact paths. -- Validation commands are part of the approved plan. Foreground Testing asks before running them, cannot edit/use Git, reports every exit status, and routes nonzero outcomes through correction without technical retry. -- One Builder fails while peers succeed: wait for all to terminate, apply the failed Builder recovery sequence, then abort all review/commit if recovery is exhausted; preserve every partial change for human inspection. -- Same-session retry uses the returned `task_id`; a fresh Builder continuation receives the original task ID, ownership, dependency state, previous session/error IDs, and instruction to inspect rather than restart or overwrite partial work. -- Reviewer critique and Builder correction remain bounded by the existing three-round circuit breaker and are not confused with Task/API retry attempts. -- Sequential CodeReviewers use explicit task/path/baseline diff scope. Rejection appends critique without approval; correction resumes that Builder, reruns validation and review, and invalidates the old diff; only final acceptance sets `[x]`. Concurrent shared review-log writes and approving unrelated “latest changes” are prohibited. -- Tasks finalize strictly one at a time as review/correction → that task's serialized `PLAN.md` update → scoped commit. Committer begins with an empty index, stages only explicit task-owned paths plus `PLAN.md`, verifies cached-path equality, tolerates only known dirty paths of other successful batch tasks, and visibly aborts on unknown dirty paths, unrelated staged paths, or an indeterminate index. -- Cancellation or process restart may leave modified files and non-durable background state. Treat status as unknown/stale, do not infer success, and require reconciliation before another dispatch. -- Librarian timeout, API error, inaccessible source, invalid source data, contradictory documentation, or partial results are written/reported as such; no fabricated citation or silent fallback is allowed. Assigned-file ownership is cooperative within the permission-enforced `docs/research/**` directory, and pre-existing targets fail unless update mode was explicit. -- Missing `docs/research`, directory/target symlinks, existing targets without update mode, and concurrent duplicate target assignment stop research visibly; the tracked directory and pre-dispatch inspection are required. -- Research topic keys and targets are reserved in the live Orchestrator session before dispatch; duplicate topic or target is rejected. Reservations end with that session, and no durable or cross-process atomic reservation or prior-child recovery is claimed. -- A new Orchestrator session cannot recover prior in-memory research reservations. It warns about this limitation, treats an existing target as requiring update mode, and may dispatch an absent target only after warning; it never claims to know old child status. -- `/archive_plan` remains functionally unchanged on Buddy. Orchestrator may warn against invoking it during active lifecycle work, but issue #101 adds no command precondition; its path/post-mortem mismatch remains out of scope. -- Issue #100 integration-bot behavior and issue #85 research verification are not implemented accidentally through generalized orchestration prompts. +- Missing, empty, malformed, unapproved, completed, or dependency-blocked `PLAN.md` stops implementation without retry. +- Replacing a nonempty plan requires explicit confirmation and preserves it on cancellation. +- Duplicate/unknown task IDs, dependency cycles, missing validation commands, ambiguous owned paths, shared lockfiles/generated outputs, and apparent path/resource overlap prevent parallel dispatch. +- At most two Builders and four distinct Librarians run concurrently; retries count toward the applicable limit. +- Background Task support is required for implementation/research parallelism; absence is disclosed and stops the phase rather than silently serializing it. +- Planner questions run only in foreground and reach the user directly. +- Builders never edit `PLAN.md`, review, or commit while a batch is active; Orchestrator never changes the plan until all batch Builders terminate. +- A Builder discovering undeclared files, conflicting edits, or unrelated concurrent changes stops and reports exact paths. +- One exhausted Builder aborts review/commit for the whole batch and leaves partial changes visible. +- Same-session retry occurs once; only Builder gets one additional fresh continuation session, which must inspect existing partial work. +- Review/test correction is separate from Task retry and remains bounded to three rounds per task. +- Tasks finalize sequentially to reduce review-log, plan-state, staging, and commit contamination. +- Unrelated staged changes or indeterminate Git scope cause Committer to abort rather than stage broadly. +- Prompt/session claims cannot prevent a second OpenCode process from touching the same worktree; this accepted limitation must remain documented. +- Cancellation or OpenCode restart may leave partial files and loses cooperative in-session scheduling state; never infer completion. +- Research target collisions, overlapping topics, inaccessible sources, API errors, contradictory data, and partial results are surfaced; no citation or conclusion is fabricated. +- Issue #100 bot behavior, issue #85 verification, worktree isolation, durable locks, custom scheduling, probe suites, and archive cleanup remain out of scope. ## Review Log (Plan Review) -- **Round 1:** Not approved. Addressed 14 blockers: added delegated read-only Git snapshots; completed retry/capacity/claim states; defined rejection, correction, and final approval transitions; made shared-index commits path-exact and task-sequential; specified Builder tools/results and correction resume; separated static checks from runtime guarantees; grounded direct child questions in OpenCode behavior; constrained Buddy and all task chains; documented the archive exception; clarified Librarian's enforced versus cooperative scope; moved synchronized-copy acceptance to T5; added sync conflict handling; split automated and manual validation; and prohibited recursive delegation. -- **Round 2:** Not approved. Addressed five blockers: explicitly changed Explorer's Git permissions; moved validation to a constrained Testing subagent; defined attempted background dispatch rejection as the capability signal; classified scheduler state/claims as cooperative and added exact JSON terminal recognition; and specified setup, fault, observation, evidence, cleanup, and pass/fail for each manual runtime case. -- **Round 3:** Not approved. Integrated the remaining actionable feedback by explaining template migration, specifying Explorer's complete permission contract, defining Testing's cooperative command matching and approval boundary, adding exact Builder/Testing JSON schemas, removing the contradictory archive precondition, defining graph normalization/overlap/cycle/approval algorithms, and requiring executable runtime fixtures/matrix rows without placeholders. The reviewer also objected to task metadata beyond the example template; this plan retains it because T2 explicitly updates the authoritative Planner template and every mandatory section/field remains present. Maximum three review rounds reached; no further automated review is permitted. -- **Additional review A (user-authorized):** Not approved. Integrated Round-4 findings: exact result schemas, deny-by-default graph, built-in bypass prevention, AGENTS ownership, complete sync checks, background feasibility gate, Committer sequence, executable validation, and research directory handling. -- **Additional review B (user-authorized):** Not approved. Integrated explicit DocumentationEngineer/system-agent treatment; Buddy-only Orchestrator targeting; Testing session identity; exclusive dual-AGENTS ownership; `tui.jsonc`/transactional sync; external pre-edit background probe; deterministic graph/path/research normalization and stale reservations; strict Committer grammar; static/runtime separation; concrete runtime rows; and removal of the non-template Round 4 field. -- **Additional review C (user-authorized):** Not approved. Added nonempty Validation Commands to every task; specified the external background probe invocation, flag, timeout, abort/wait/trap cleanup, and evidence schema; defined a literal runtime fixture helper/command pattern and exact event/Git assertions per case; replaced contradictory session-only research retention with a durable reservation ledger and deterministic stale reconciliation; and required Testing session-envelope equality plus nonempty ordered validation. -- **Additional review D (user-authorized):** Not approved. Assigned the background checker/evidence to T1 and specified external probe invocation/API inspection/timeout/abort/wait/copy cleanup; replaced runtime `CASE` placeholders with literal named helper subcommands, paths, prompts, and assertions; rejected misleading non-atomic durable research state in favor of explicit post-restart child-status/target reconciliation; and added negative result fixtures for empty lists, session mismatch, and omitted/reordered/extra commands. -- **Additional review E (user-authorized):** Not approved. Removed the missing preflight-script source dependency by specifying a shell-only installed-version probe that becomes the tracked checker only after proof; replaced unenforceable raw-Git permissions with a shell-free scoped-commit wrapper and tests; defined concrete event/Git predicates for every runtime class; and removed unobservable research child recovery in favor of explicit no-guarantee restart behavior. +- **Round 1:** Approved. The streamlined OpenCode-native plan is internally consistent, preserves the explicitly chosen cooperative limitations, and is implementable without custom scheduling or probe infrastructure. +- **Round 2:** N/A +- **Round 3:** N/A ## Final Status (Code Review) From efe4df3fde244260025b3fb1960e2c39b4337eea Mon Sep 17 00:00:00 2001 From: Martin Kuckert Date: Sat, 29 Aug 2026 10:13:44 +0000 Subject: [PATCH 03/10] feat: adopt Orchestrator lifecycle from agent-harness (issue #101) Sync .opencode/ from the agent-harness submodule (new Orchestrator, hidden Planner/Builder/Testing, deny-by-default task mappings, /plan + /continue_implementation, durable /research notes).

Do not implement verification, a shared index, skills, or durable scheduling metadata. - - **Review Criteria:** Librarian cannot modify source, configuration, `PLAN.md`, or files outside `docs/research/**`; concurrent requests use distinct topic/file scopes; existing targets require explicit update intent; API/source failures and partial findings are visible; no `SKILL.md`, verification workflow, or scheduling ledger is introduced. + - **Description:** Update Librarian permissions to allow writes and exact-target glob checks only under workspace-relative `research/results/**`, create that directory in the authoritative harness, and follow the Research Artifact Contract for timestamped topic filenames, metadata, findings, source URLs/version context, limitations, and partial/failure status.

Add lightweight dependency-free static checks for agent modes, Task target mappings, built-in disablement, depth/default configuration, command routing/removal, required plan task fields, and Librarian write confinement. Add a concise manual smoke checklist for: Planner question flow; one and two Builder execution; overlap rejection; missing background support; same-session retry and Builder fresh continuation; failed-batch no-review/no-commit; validation/review correction; scoped sequential commits; up to four distinct Librarians; and Buddy natural-language delegation. Use `harness-sync.sh` to propagate authoritative `.opencode` and config changes to the parent project, stop visibly on conflict/cancellation, check for rejected patches, and confirm final sync status has no unintended drift. Validate the separately maintained `opencode/opencode.jsonc` and restart OpenCode before manual smoke checks. - **Review Criteria:** Static checks pass without new libraries; manual smoke results are recorded as pass/fail with brief evidence; OpenCode loads all changed config/frontmatter; expected primary/subagent modes and command targets are discoverable; parent and authoritative synchronized paths agree without rejected patches or unintended drift; depth is `5` in both intended configs; documentation clearly distinguishes cooperative prompt coordination from enforced isolation. diff --git a/agent-harness b/agent-harness index 310075f..b264f0d 160000 --- a/agent-harness +++ b/agent-harness @@ -1 +1 @@ -Subproject commit 310075fb48e4bf9024b0cb95d767d0c22bcee1f5 +Subproject commit b264f0ddd5f388b9bcc99f3ae68b501e39c6ab33 diff --git a/opencode.jsonc b/opencode.jsonc index bc2a619..c3b2d0a 100644 --- a/opencode.jsonc +++ b/opencode.jsonc @@ -1,5 +1,6 @@ { "$schema": "https://opencode.ai/config.json", + "default_agent": "Buddy", "agent": { "plan": { "disable": true, From 1a0c338b979d03ac175f020c66eb7197b5c0487e Mon Sep 17 00:00:00 2001 From: Martin Kuckert Date: Fri, 4 Sep 2026 22:11:54 +0200 Subject: [PATCH 06/10] fix: Makes some necessary adjustments --- .nono/profile.json | 2 +- .opencode/agents/Buddy.md | 4 ++-- .opencode/agents/Builder.md | 3 ++- .opencode/agents/Committer.md | 2 +- .opencode/agents/Planner.md | 1 - .opencode/agents/Testing.md | 1 - 6 files changed, 6 insertions(+), 7 deletions(-) diff --git a/.nono/profile.json b/.nono/profile.json index 2cb7605..b0dc605 100644 --- a/.nono/profile.json +++ b/.nono/profile.json @@ -5,7 +5,7 @@ "name": "env" }, "filesystem": { - "allow": [], + "allow": ["~/env"], "deny": [], "read_file": [], "read": ["~/.config/gh"] diff --git a/.opencode/agents/Buddy.md b/.opencode/agents/Buddy.md index 1baf178..0d7a538 100644 --- a/.opencode/agents/Buddy.md +++ b/.opencode/agents/Buddy.md @@ -12,7 +12,7 @@ permission: bash: "*": allow "nono why *": allow - git *: deny + "git *": deny question: allow task: "*": deny @@ -50,6 +50,6 @@ You are a senior software engineer with expertise in creating comprehensive, mai -You are the default general-purpose primary agent and retain general assistance for unrelated work.

Set `subagent_depth` to `5` in `agent-harness/opencode.jsonc` and the separate `opencode/opencode.jsonc` runtime configuration. -- **Chosen Libraries:** None. OpenCode-native delegation is sufficient. Prompt-coordinated shared-worktree execution is an explicit user decision; no new orchestration library, SQLite ledger, custom scheduler, atomic claim service, Git worktree isolation, scoped-commit wrapper, or background compatibility probe is part of issue #101. -- **Error Handling Strategy:** Fail loudly and preserve the child error, phase, task/topic, session ID when available, and attempt count. On a technical Task failure (timeout, API/tool error, step-limit/incomplete result, unavailable session), resume the same child session exactly once. If a Builder still fails, launch one fresh Builder session with the original task scope and instructions to inspect and continue partial work; if it also fails or stops, halt the implementation batch and report briefly. Other subagents stop after the failed resume. Review critique, test failure, user rejection, and invalid workflow state are not technical Task failures and do not trigger this retry sequence. If background Task execution is unavailable, disclose that the required harness feature is missing and stop; do not silently fall back to serial execution. -- **Scope Boundary:** Issue #101 establishes the lifecycle agent architecture. It does not implement issue #100's GitHub bot, issue #85's research-verification workflow, durable cross-session scheduling, atomic filesystem locks, transactional rollback, or archive-command cleanup. `/archive_plan` remains assigned to Buddy and functionally unchanged. -- **Primary Agents:** Buddy remains the default general-purpose primary agent. Orchestrator uses the OpenCode mode that makes it user-selectable and Task-delegable. Planner and Builder become hidden subagents. Buddy delegates lifecycle requests to Orchestrator and retains general assistance for unrelated work. -- **Planner Questions:** Planner remains allowed to use `question` while running as a foreground Task. Orchestrator waits while the child question is presented to the user. Interactive planning is never dispatched in the background. -- **Delegation Graph:** Use deny-by-default Task target rules. Buddy may invoke Orchestrator, Explorer, and Librarian. Orchestrator may invoke Planner, Builder, Testing, PlanReviewer, CodeReviewer, Explorer, and Librarian, but not Committer. Planner may invoke Explorer, Librarian, and PlanReviewer. Builder may invoke Committer only during Orchestrator-authorized finalization. PlanReviewer and CodeReviewer may invoke Explorer and Librarian. Explorer, Librarian, Testing, and Committer are leaves. Built-in `plan`, `build`, `general`, and `explore` remain disabled in harness project configuration so lifecycle work cannot bypass Orchestrator. -- **Plan Dependency Graph:** Extend Planner's mandatory task format with `Task ID`, `Depends On`, `Owned Paths`, `Shared Resources`, `Parallel Safe`, and `Validation Commands`, in addition to `Description` and `Review Criteria`. IDs must be unique; dependencies must reference known tasks and be acyclic; dependency-ready means all prerequisites are `[x]`. Paths must be repository-relative and explicit enough to compare. PlanReviewer rejects ambiguous ownership, undeclared shared files/resources, unsafe validation commands, and parallel-safe tasks with apparent overlap. `PLAN.md` is the durable graph; Orchestrator may clarify its scheduling metadata only while no Builder is active. -- **Cooperative Parallelism:** `/continue_implementation` replaces `/implement_next_task`. It may launch at most two dependency-ready Builders whose approved tasks are explicitly parallel-safe and have disjoint declared paths/resources. The Orchestrator encourages parallelism only when this is clear; otherwise it runs one task or asks. Claims, overlap avoidance, and the two-agent limit are prompt/session coordinated—not atomic or safe across independent OpenCode processes. Builders must stop and report if they discover undeclared overlap or unrelated concurrent changes. Multiple Librarians may run in parallel up to four when assigned distinct topics. -- **Implementation Batch Barrier:** Active Builders modify only their assigned task scope and do not edit `PLAN.md`, invoke review, or commit. Orchestrator waits for all Builders in the selected batch. If one exhausts recovery, no task in that batch proceeds to review/commit. If all succeed, Orchestrator finalizes tasks one at a time: run approved validation through Testing, invoke task-scoped CodeReviewer, return critique to the corresponding Builder, and repeat for at most three review/correction rounds. Only accepted review changes that task to `[x]`; Builder then invokes Committer for that task. This sequencing reduces shared `PLAN.md` and Git-index races but does not make the shared worktree transactional. -- **Research:** `/research` routes directly from Orchestrator to Librarian rather than Builder. Librarian may write only under workspace-relative `research/results/**` and writes durable research notes, not `SKILL.md`. Librarians create timestamped topic filenames and check for an existing exact target before writing. Research verification remains issue #85. Parallel topic scopes are session-local and cooperative; no restart guarantee is claimed. -- **Command Preconditions:** `/plan` asks before replacing a nonempty `PLAN.md`. `/continue_implementation` stops for a missing, malformed, unapproved, completed, dependency-blocked, or scope-conflicting plan. `/review_plan` requires a plan. `/review_code` requires a plan plus an identifiable task/change scope and no longer performs a vague general review. Deterministic precondition failures are reported without retry. - -## Implementation Steps - -> Status Markers: [ ] Open, [/] In Progress, [x] Completed (set after accepted review only!) - -- [ ] **Task 1: Introduce the Orchestrator and update agent modes** - - **Description:** Add `agent-harness/.opencode/agents/Orchestrator.md` as a selectable/delegable lifecycle coordinator.

Update PlanReviewer to reject missing/invalid dependencies, cycles, unsafe or ambiguous ownership, and apparent overlap among parallel tasks. Change Builder from selecting “the first open task” to implementing only the Orchestrator-supplied task ID/scope; it must not edit `PLAN.md`, review, or commit during an active batch and must report modified paths, validation requested, and concerns. Make Testing a hidden non-editing subagent that runs only plan-approved validation with user approval where required. Make CodeReviewer task/scope-specific, with critique leaving the task incomplete and acceptance alone setting `[x]`. Update Committer to stage only the task paths explicitly supplied by Builder plus the serialized `PLAN.md` change and to fail visibly if unrelated staged changes make scope unclear. Reconcile root and `agent-harness/AGENTS.md` so the Orchestrator batch workflow supersedes direct per-unit commits for harness lifecycle work. - - **Review Criteria:** New plans contain enough dependency/scope data for scheduling; PlanReviewer rejects obvious graph/overlap errors; Builder cannot autonomously choose another task or mutate plan state during implementation; Testing cannot edit source or use Git; CodeReviewer reviews one identified task and controls `[x]`; Committer is instructed to avoid broad staging and aborts on ambiguous index state; both AGENTS files describe the same lifecycle flow. -- [ ] **Task 3: Route and rename lifecycle commands** - - **Description:** Add the parent-only `/plan` command to the authoritative harness and route it through Orchestrator. Replace `/implement_next_task` with `/continue_implementation`; support optional task IDs or a serial request while defaulting to the maximum safe eligible set of at most two tasks. Route `/review_plan`, `/review_code`, and `/research` through Orchestrator. Preserve `$ARGUMENTS` as a scope-narrowing input. Change `/research` from skill generation to durable research notes. Keep `/archive_plan` as the documented Buddy-owned exception. - - **Review Criteria:** All lifecycle commands except `/archive_plan` target Orchestrator; the old implementation command is removed; `/continue_implementation` cannot exceed two Builders and does not broaden an explicit task/serial request; invalid states fail before child dispatch; `/review_code` cannot perform an unscoped review; `/research` does not invoke Builder or create a skill; `/archive_plan` remains unchanged. -- [ ] **Task 4: Enable durable Librarian research notes** - - **Description:** Update Librarian permissions to allow writes and exact-target glob checks only under workspace-relative `research/results/**`, create that directory in the authoritative harness, and follow the Research Artifact Contract for timestamped topic filenames, metadata, findings, source URLs/version context, limitations, and partial/failure status. Orchestrator dispatches at most four distinct topics. Do not implement verification, a shared index, skills, or durable scheduling metadata. - - **Review Criteria:** Librarian cannot modify source, configuration, `PLAN.md`, or files outside `research/results/**`; concurrent requests use distinct topic scopes; an existing exact target is never overwritten; API/source failures and partial findings are visible; no `SKILL.md`, verification workflow, or scheduling ledger is introduced. -- [ ] **Task 5: Synchronize, document, and validate the streamlined architecture** - - **Description:** Update `agent-harness/README.md` with the agent graph, command mapping, question flow, retry rules, cooperative parallel limits, batch finalization, research location, and explicit non-atomic/cross-session limitations. Add lightweight dependency-free static checks for agent modes, Task target mappings, built-in disablement, depth/default configuration, command routing/removal, required plan task fields, and Librarian write confinement.

Update Committer to stage only the task paths explicitly supplied by Builder plus the serialized `PLAN.md` change and to fail visibly if unrelated staged changes make scope unclear. Reconcile root and `agent-harness/AGENTS.md` so the Orchestrator batch workflow supersedes direct per-unit commits for harness lifecycle work. + - **Review Criteria:** New plans contain enough dependency/scope data for scheduling; PlanReviewer rejects obvious graph/overlap errors; Builder cannot autonomously choose another task or mutate plan state during implementation; Testing cannot edit source or use Git; CodeReviewer reviews one identified task and controls `[x]`; Committer is instructed to avoid broad staging and aborts on ambiguous index state; both AGENTS files describe the same lifecycle flow. +- [ ] **Task 3: Route and rename lifecycle commands** + - **Description:** Add the parent-only `/plan` command to the authoritative harness and route it through Orchestrator. Replace `/implement_next_task` with `/continue_implementation`; support optional task IDs or a serial request while defaulting to the maximum safe eligible set of at most two tasks. Route `/review_plan`, `/review_code`, and `/research` through Orchestrator. Preserve `$ARGUMENTS` as a scope-narrowing input. Change `/research` from skill generation to durable research notes. Keep `/archive_plan` as the documented Buddy-owned exception. + - **Review Criteria:** All lifecycle commands except `/archive_plan` target Orchestrator; the old implementation command is removed; `/continue_implementation` cannot exceed two Builders and does not broaden an explicit task/serial request; invalid states fail before child dispatch; `/review_code` cannot perform an unscoped review; `/research` does not invoke Builder or create a skill; `/archive_plan` remains unchanged. +- [ ] **Task 4: Enable durable Librarian research notes** + - **Description:** Update Librarian permissions to allow writes and exact-target glob checks only under workspace-relative `research/results/**`, create that directory in the authoritative harness, and follow the Research Artifact Contract for timestamped topic filenames, metadata, findings, source URLs/version context, limitations, and partial/failure status. Orchestrator dispatches at most four distinct topics. Do not implement verification, a shared index, skills, or durable scheduling metadata. + - **Review Criteria:** Librarian cannot modify source, configuration, `PLAN.md`, or files outside `research/results/**`; concurrent requests use distinct topic scopes; an existing exact target is never overwritten; API/source failures and partial findings are visible; no `SKILL.md`, verification workflow, or scheduling ledger is introduced. +- [ ] **Task 5: Synchronize, document, and validate the streamlined architecture** + - **Description:** Update `agent-harness/README.md` with the agent graph, command mapping, question flow, retry rules, cooperative parallel limits, batch finalization, research location, and explicit non-atomic/cross-session limitations. Add lightweight dependency-free static checks for agent modes, Task target mappings, built-in disablement, depth/default configuration, command routing/removal, required plan task fields, and Librarian write confinement. Add a concise manual smoke checklist for: Planner question flow; one and two Builder execution; overlap rejection; missing background support; same-session retry and Builder fresh continuation; failed-batch no-review/no-commit; validation/review correction; scoped sequential commits; up to four distinct Librarians; and Buddy natural-language delegation. Use `harness-sync.sh` to propagate authoritative `.opencode` and config changes to the parent project, stop visibly on conflict/cancellation, check for rejected patches, and confirm final sync status has no unintended drift. Validate the separately maintained `opencode/opencode.jsonc` and restart OpenCode before manual smoke checks. + - **Review Criteria:** Static checks pass without new libraries; manual smoke results are recorded as pass/fail with brief evidence; OpenCode loads all changed config/frontmatter; expected primary/subagent modes and command targets are discoverable; parent and authoritative synchronized paths agree without rejected patches or unintended drift; depth is `5` in both intended configs; documentation clearly distinguishes cooperative prompt coordination from enforced isolation. + +## Edge Case & Safety Checklist + +- Missing, empty, malformed, unapproved, completed, or dependency-blocked `PLAN.md` stops implementation without retry. +- Replacing a nonempty plan requires explicit confirmation and preserves it on cancellation. +- Duplicate/unknown task IDs, dependency cycles, missing validation commands, ambiguous owned paths, shared lockfiles/generated outputs, and apparent path/resource overlap prevent parallel dispatch. +- At most two Builders and four distinct Librarians run concurrently; retries count toward the applicable limit. +- Background Task support is required for implementation/research parallelism; absence is disclosed and stops the phase rather than silently serializing it. +- Planner questions run only in foreground and reach the user directly. +- Builders never edit `PLAN.md`, review, or commit while a batch is active; Orchestrator never changes the plan until all batch Builders terminate. +- A Builder discovering undeclared files, conflicting edits, or unrelated concurrent changes stops and reports exact paths. +- One exhausted Builder aborts review/commit for the whole batch and leaves partial changes visible. +- Same-session retry occurs once; only Builder gets one additional fresh continuation session, which must inspect existing partial work. +- Review/test correction is separate from Task retry and remains bounded to three rounds per task. +- Tasks finalize sequentially to reduce review-log, plan-state, staging, and commit contamination. +- Unrelated staged changes or indeterminate Git scope cause Committer to abort rather than stage broadly. +- Prompt/session claims cannot prevent a second OpenCode process from touching the same worktree; this accepted limitation must remain documented. +- Cancellation or OpenCode restart may leave partial files and loses cooperative in-session scheduling state; never infer completion. +- Research target collisions, overlapping topics, inaccessible sources, API errors, contradictory data, and partial results are surfaced; no citation or conclusion is fabricated. +- Issue #100 bot behavior, issue #85 verification, worktree isolation, durable locks, custom scheduling, probe suites, and archive cleanup remain out of scope. + +## Review Log (Plan Review) + +- **Round 1:** Approved.

Employ efficient parsing methods to capture only the essential technical core. -- **Persist before responding:** Every invocation, including direct calls, must write exactly one research artifact before its final response. The destination is relative to the invoking workspace: `research/results/.md`. Do not commit the artifact and do not write anywhere else. -- **Prepare a safe filename:** Derive a topic slug by lowercasing only ASCII letters, retaining `[a-z0-9]`, replacing every run of other characters with one hyphen, trimming edge hyphens, and truncating to 80 characters without a trailing hyphen. Do not transliterate Unicode. Reject the run before writing if the slug is empty or contains `/`, `\\`, or `..`. Name the file `YYYYMMDDTHHMMSSZ--.md`, where the timestamp is UTC and the suffix is a newly generated high-entropy ASCII lowercase alphanumeric value. The resulting filename must contain no separators or traversal segments. -- **Refuse collisions:** Before writing, use `glob` only within `research/results/*.md` to check the exact candidate filename. If it is returned, generate a new high-entropy suffix and check again; if a collision remains or the check fails, report the target path and error and do not write.

Every required value, including `libraries` and `sources`, must be a double-quoted YAML string; serialize multiple values as one escaped string rather than a YAML sequence. Escape backslashes, double quotes, and control characters in every scalar. Never interpolate untrusted text as YAML structure. Set `name` to `"research-"`, `created` to an ISO UTC timestamp, `verified` to `"false"`, `researcher.agent` to `"Librarian"`, and `researcher.model` to the configured model identifier. Abort and report an error if any required metadata is missing, non-string, or cannot be safely serialized. -- **Record provenance and limitations:** Include all consulted URLs and supplied inputs in both `metadata.sources` and `## Sources`, with their access outcome. Keep inaccessible URLs, timeouts, API errors, empty results, and version ambiguity with their failure reason; never silently omit them. Use `metadata.status: "partial"` and explicit limitations whenever any such condition prevents complete research. Use `"complete"` only when the evidence supports it.

Never claim persistence after a failed write. If research is partial and persistence fails, report both the research limitations and persistence failure, with no success path. -- **Final response:** Only after a successful write, start the final response with the exact stable handoff line `Research artifact: research/results/.md`, substituting the written filename, followed by a concise synthesis.
