fix(eve): classify input requests by framework-owned kind by ruiconti · Pull Request #1319 · vercel/eve

ruiconti · 2026-07-29T13:21:11Z

Input requests come from three producers — ask_question, AI SDK tool approvals, and the session-limit continuation gate — but consumers classified them by option shape, display hints, and tool names. Those heuristics drift: shape-sniffing misclassified the session-limit prompt as a tool approval, and the TUI rendered it through the y/n approval flow where its continue/stop options could not be answered.

What

Add a required InputRequest.kind discriminator (question / tool-approval / session-limit), stamped by each producer.
Classify, route, and render by kind across the harness, clients, and channels: classifyInputRequest becomes an exhaustive switch, the TUI renders non-approvals in the question pane (answering with the request's own option ids), and Slack/Teams HITL use the same predicate.
Carry kind through the invocation-facing contract (eve invoke landed on main building requests without it).

Breaking

kind is a required field, so the extension compatibility contracts bump: dynamicTool v5, hook v3, dynamicInstructions v2, dynamicSkill v2.

Stack

Based on #1262. #1273 (descendant Stop cancellation, which routes by kind) and #1312 (TUI regression coverage) layer on this.

Input requests come from three producers -- ask_question, AI SDK tool approvals, and the session-limit continuation gate -- but consumers classified them by option shape, display hints, and tool names. Those heuristics drift: a prompt with its own options misclassified as an approval, and the TUI rendered the session-limit prompt through the y/n approval flow where its continue/stop options were unanswerable. Add a required InputRequest.kind discriminator (question, tool-approval, session-limit) stamped by each producer, and classify, route, and render by it across the harness, clients, and channels. The invocation-facing contract carries kind as well. Extension compatibility contracts bump: dynamicTool v5, hook v3, dynamicInstructions v2, dynamicSkill v2.

Closes #25. ## Upstream change [vercel/eve#1319](vercel/eve#1319) — `fix(eve): classify input requests by framework-owned kind`, merged as [`98d17c789bdc`](vercel/eve@98d17c7). Verified directly against upstream rather than the radar summary: - `packages/eve/src/runtime/input/types.ts` adds a **required** `kind` to `inputRequestSchema`, typed as `z.enum(["question", "session-limit", "tool-approval"])`. - `packages/eve/src/client/message-action-parts.ts` and `message-reducer-types.ts` carry it into the client-facing input request so consumers route by the discriminator instead of shape-sniffing options, display hints, or tool names. First released in eve **0.28.0** — confirmed by unpacking the npm tarballs: `0.27.13` has no `"session-limit"` literal, `0.28.0` does. ## Changes - `EveInputRequestKind` models `Question`, `ToolApproval`, `SessionLimit`, and `Unknown`. - `EveInputRequest.Kind` projects the discriminator; `EveInputRequest.RawKind` preserves the wire value. - The two `Unknown` cases stay distinguishable: a newer eve sending an unmodelled kind keeps its value in `RawKind`, while a server that predates the discriminator reports `null`. - A `kind` that is present but not a string throws `EveProtocolException` rather than impersonating a legacy server — consistent with how the parser already rejects a malformed `options` value. - `docs/attachments-and-input.md` and `docs/compatibility.md` document routing and the two `Unknown` cases. ## Validation | Gate | Result | |---|---| | `dotnet format --verify-no-changes` | clean | | `dotnet build -c Release` | 0 warnings, 0 errors | | `dotnet test -c Release` | **88 passed**, 0 failed, 0 skipped (79 pre-existing + 9 new) | | `npm run test:client` (real eve `0.27.6` server) | passed | | `mkdocs build --strict` | built | New coverage: all three kinds; a `session-limit` request carrying a `confirmation` hint, `continue`/`stop` options, and a tool name — the exact shape the old heuristic misclassified; a `question` carrying approve/deny options; an unmodelled future kind; an absent kind; a non-string kind; multiple requests in one event keeping their own kinds; and an assertion that the nested `action.kind` is never read as the request discriminator. The pinned eve `0.27.6` fixture gains an approval-gated tool (`agent/tools/request_approval.ts` with `approval: always()`), and the mock model emits a matching tool call. The compatibility probe therefore drives a **real** `input.requested` pause, asserts the legacy projection (`Kind == Unknown`, `RawKind == null`), then answers the approval and verifies the turn resumes. ## Disclosed gaps **HIGH — none.** **MEDIUM** - The compatibility baseline is intentionally **not** advanced. `EveProtocol.ReferenceEveVersion` stays `0.27.6`, because the issue requires all changes through the upstream release to land first, and eve 0.28.0 also carries the stream-event-id change tracked by #24. Advancing the pinned fixture should be a separate PR once both are merged. - Because the pinned fixture is `0.27.6`, discriminator **presence** is verified only against synthetic payloads. Only the legacy-tolerance half is verified against a real server. - `session-limit` cannot be produced by the pinned fixture, so it is covered by contract tests only. **LOW** - `EveInputRequestKind` is a plain enum. Adding a future kind is additive and non-breaking, but a caller switching exhaustively today will fall through to `Unknown`; `RawKind` is the documented escape hatch. - The fixture tool uses a plain JSON Schema `inputSchema` rather than Zod, so no new fixture dependency and no lockfile change was needed.
