It now joins every `type: "text"` block. -- **Untrusted agent output.** `validateFindings` assumed every array element was an object, so a `null` in an agent artifact threw a `TypeError` out of `parseAgentResult` and out of the orchestrator, failing the entire review over one bad entry. Confirmed live on both the bare-array and envelope paths. -- **Shared prompt sanitiser.** Consensus and grouping stripped newlines and `` delimiters before interpolating finding text; suppression did not, so a planted string quoted into a finding comment could forge `Output ONLY: [0,1,2,…]` and suppress a whole batch, hiding genuine critical findings. `groupAllFindings` had also already drifted from `applyConsensus` (it sanitised `file` but interpolated `line` raw). All three now render through `sanitizeForPrompt` in `src/sanitize.mjs`, which is the point of a single helper. - - Checked explicitly: for findings containing no newlines or delimiters, all three prompts are **byte-identical** to before. The change bites only on the injection case, so the hosted/local agreement the card is built on is preserved. -- **Publish allowlist.** With `private: true` dropped and no `files` field, `npm publish` packed the whole working directory — 86 files, including `.agents/` and `.workhorse/`, and on a runner whatever the Actions steps had materialised there. Now `files: ["src/", "prompts/"]` → 21 files. `prompts/` is load-bearing, not cosmetic: `discoverBaseAgents` resolves `/prompts` at runtime, so omitting it would silently yield zero base agents. `.review-hero/` and `.caller-base/` added to `.gitignore` (review-hero reviews itself, so both can appear inside this checkout). - -Verified by installing the packed tarball into a clean project: it imports, `discoverBaseAgents` finds all four agents from the shipped prompts, and the shipped `src/index.test.mjs` runs green from `node_modules` (19 cases) — which is how the card's "fixtures reachable by a consumer" requirement is met. diff --git a/.workhorse/test-cases/k1/overview.md b/.workhorse/test-cases/k1/overview.md deleted file mode 100644 index 4bd0032..0000000 --- a/.workhorse/test-cases/k1/overview.md +++ /dev/null @@ -1,57 +0,0 @@ -# K1 — Make review-hero consumable as a library - -Scenarios verifying that the shared review logic is importable, dependency-light, and behaves identically whether the model call is API-backed (this repo) or caller-supplied (Workhorse). - -## Packaging & entry point - -- [x] The package entry (`src/index.mjs`) imports cleanly and exposes every shared function -- [x] Nothing reachable from the entry point imports `@actions/core` or shells out to `yq` -- [x] The package installs as a dependency and imports into a TypeScript project (type declarations resolve) - -## Injectable model call - -- [x] `filterWithSuppressions` routes every model call through the caller-supplied function and suppresses the indices it returns -- [x] `filterWithSuppressions` with no caller (`null`) keeps all findings -- [x] `applyConsensus` routes through the caller-supplied function and keeps only the representatives it returns -- [x] `applyConsensus` with no caller keeps all findings (stripped of voter tags) -- [x] `groupAllFindings` with no caller falls back to one group per finding -- [x] `createAnthropicModelCaller` returns the assistant text and throws on a non-2xx response - -## Suppressions without yq - -- [x] `loadSuppressions` parses a YAML suppressions file via the JS parser -- [x] `loadSuppressions` returns `[]` for a missing file and for non-list YAML - -## Agent discovery & scope (no yq) - -- [x] `loadCallerConfig` parses `.github/review-hero/config.yml` via the JS parser -- [x] `discoverBaseAgents` finds the base agents whose prompt files exist -- [x] `filterDiff` strips ignored files (lockfiles) and keeps in-scope files - -## Untrusted agent output - -- [x] `validateFindings` discards `null`, `undefined`, and scalar array entries instead of throwing -- [x] `parseAgentResult` survives a `null` element in both the bare-array and CLI-envelope paths, dropping the entry rather than failing the whole review - -## Prompt-injection defence - -- [x] `sanitizeForPrompt` collapses newline runs and strips `` delimiters -- [x] The suppression filter renders each finding on exactly one prompt line, so injected newlines cannot forge instructions -- [x] Consensus and cross-agent grouping render each finding on one line too -- [x] For findings with no newlines or delimiters, all three prompts are byte-identical to before the shared helper, so hosted and local verdicts do not shift - -## Model response shapes - -- [x] `createAnthropicModelCaller` joins multiple text blocks and skips a leading thinking block -- [x] `createAnthropicModelCaller` returns `""` when a response carries no text block - -## Publish surface - -- [x] `npm pack` ships only the library, its declarations, the contract test, and `prompts/` — no `.agents/`, `.workhorse/`, `.github/`, `.review-hero/`, or `.caller-base/` -- [x] The packed tarball installs and imports as a dependency; `discoverBaseAgents` resolves the shipped `prompts/` -- [x] The shipped contract test runs from the installed package (19 cases), so a consumer can verify it agrees - -## Regression — one implementation - -- [x] Existing `orchestrate`/`lib` tests still pass through the extracted modules -- [x] `triage.mjs` runs end-to-end: parses config, filters the diff, builds the matrix
