See `finding-coverage.md` → +_Finding existing coverage_ and _Citing tests as GitHub permalinks_ for the link form and the +fallback when ingredients are missing. + +## Technical breakdown document + +A Bitwarden **Tech Breakdown** — the Markdown artifact a team produces before implementation, +living in the [`bitwarden/tech-breakdowns`](https://github.com/bitwarden/tech-breakdowns) GitHub +repo. It is the richest single input for this analysis, because a good breakdown has already done +the cross-platform scoping you would otherwise reconstruct from a diff or a ticket. Mine it; don't +re-derive it. + +The repo is organized by team: each team folder (e.g. `platform/`) holds one breakdown per work +item, named `<JIRA-KEY>-<slug>.md` (e.g. `platform/PM-30935-flight-recorder-phase-2.md`). The +canonical structure is `templates/breakdown.md`. **Completed breakdowns** — where the code has +shipped and the implementation, not the document, is now the source of truth — move to a +`<team>/complete/` subfolder; treat those as historical context, not current scope. + +Locate and fetch it (GitHub-only, via `gh`): + +- Given a path or GitHub URL, read it with + `gh api repos/bitwarden/tech-breakdowns/contents/<path>` (decode the base64 `content`). +- Given only a feature or team name, find it with + `gh search code --repo bitwarden/tech-breakdowns <terms>`, or list the team folder with + `gh api repos/bitwarden/tech-breakdowns/contents/<team>` and match by `<JIRA-KEY>-<slug>`. +- A breakdown not in the repo is simply a missing input — record it as not-inspected and move on; + never block on it. + +Map its structure to testable evidence (sections per `templates/breakdown.md`): + +- **`## Status`**: the maturity gate. `In Planning` / `In Progress` means scope may still shift — + note the inventory rests on a draft. `Proposed` / `Accepted` is a stable basis. `Complete` means + the implementation supersedes the doc. Record the status as part of the evidence. +- **`# Specification`** (Functional Requirements, Success Criteria): the discrete **testable + behaviors** and acceptance criteria. The linked Jira epic named here is an Epic-key intake — + drill into its children and their PR remote links per the _Epic intake_ recipe above. A breakdown + plus its epic together usually surface more testable behavior than either alone. +- **`# Plan`** per-surface subsections: each names a surface the change touches and therefore a + place tests may exist — **Data model changes** (migration/backwards-compat behaviors), + **Server API surface changes** (endpoint contracts, version compatibility, unauthenticated + endpoints), **Client / UI behavior changes**, **`sdk-internal` changes**, **Client services + changes**, **Background jobs**, **Security & cryptography** (crypto, threat-model-relevant + behaviors), and **Deployment & environments** (Self-Hosted vs Cloud, feature-flag on/off + states). The **Testing strategy** subsection is the team's own stated test intent — treat it as + a claim to assess, not ground truth to copy. +- **`# Agent Context`** (Repos affected, Existing patterns to follow, External references): maps + surfaces to the repos/platforms touched (→ `test-layers-and-repos.md`) and points at the concrete + code and PRs where tests live. +- **`# Tasks`** (and the sibling `tasks.md` in the same folder): the work items carved from the + breakdown; follow their linked PRs into the **GitHub PR** branch above. + +Extract: discrete **testable behaviors** per platform, the **surfaces** each touches (→ repos via +`test-layers-and-repos.md`), and the team's **stated testing intent** (to evaluate, not echo). +**Prefer the implementation over the breakdown when they conflict** — the shipped code and merged +PRs are the current source of truth; a breakdown (especially one not yet `Complete`) describes +intent that may have drifted. Where the breakdown disagrees with a diff or ticket you were also +given, prefer the implementation and record the divergence as a finding rather than silently +picking one. + +## Test-case CSV export + +A CSV export of existing or planned test cases. Column headers vary by tool and export +settings — **do not hardcode them**. Read the header row, then map by meaning: + +- A **title / case** column — the scenario name. +- A **type** column (e.g. "Regression", "Smoke", "Functional") — hints at intended layer. +- An **automation status** column (e.g. "Ready to Automate", "Automated", "Manual") — + what already exists vs. what's planned. +- A **steps / expected-result** column, often in Given–When–Then form — the behavior. +- Optional **team / area / tags / preconditions** columns — scope and grouping. + +Map rows to behaviors and bucket each by apparent layer using `test-layers-and-repos.md`: + +- A case that drives the full UI through a complete journey → likely **E2E** (the dedicated + `test` repo). +- A case asserting one service/component's behavior through its collaborators → + **integration**. +- A case pinning a single function's logic or an edge case → **unit**. + +If a column's meaning is ambiguous, state the interpretation you used rather than guessing silently. + +## Citing Jira issues as links + +Every Jira item the report **names**, and every behavior **found from a Jira item**, is rendered as +a clickable link — never bare key text. This is the Jira counterpart to the GitHub permalink rule +for tests (`finding-coverage.md` → _Citing tests as GitHub permalinks_). + +The link form is the issue's browse URL `https://bitwarden.atlassian.net/browse/<KEY>` (e.g. +`PM-1234`). Prefer the URL the `researching-jira-issues` skill returns; else construct it +from the key. The same rule covers epics and their children — link each to its own key. Apply it: + +- An **issue, epic, or child key** named in Overview/Summary/Evidence — anchor the key as a markdown + link: `[PM-1234](https://bitwarden.atlassian.net/browse/PM-1234)`. +- A **behavior row** (coverage/gaps) extracted from a Jira item — append the linked source key to the + behavior cell.

Today it ships one capability — the **`assessing-test-coverage`** skill — and is designed to grow additional testing capabilities over time. - -Given a change, the skill finds the existing tests, buckets each by layer, cites it as a stable GitHub permalink, and flags untested behaviors as honest gaps — writing it all to a self-contained markdown coverage report. It is deliberately **backward-looking**: it does not recommend new tests, assign layers, or judge test shape. - -## Features - -- **Evidence-grounded inventory**: Reports only coverage it can observe and cite — a behavior with no observed test is recorded as a gap, never assumed covered. -- **PRs-first discovery**: Takes tests in linked/merged PR diffs as the primary evidence, then a targeted lookup scoped to the change surface — never a repo-wide sweep. -- **Layer bucketing**: Sorts each observed test into unit / integration / E2E per repo, using each repo's own conventions. -- **Stable permalink citations**: Cites 1–3 representative tests per behavior as GitHub permalinks on the repo's current default branch (not PR-head SHA links, which can point at code later reverted), plus an approximate count. -- **Inspects before it concludes**: Escalates rather than guessing when a repo isn't checked out — grep if it's cloned, otherwise clone it shallow or search it via `gh` — and falls back to `unverified` only when a surface is truly unreachable. -- **Self-contained report**: Writes a markdown coverage report — Overview, Evidence & sources, Coverage, and Gaps — to a timestamped markdown file under `${CLAUDE_PLUGIN_DATA}/coverage-reports/`. +A toolkit of skills that support Bitwarden's testing and quality work with evidence grounded in our repos, layers, and where our tests actually live. Skills can be invoked individually and the toolkit is designed to grow over time.
