# HARNESS-003: Three lesson-driven harness scans — SPEC path existence, workspace-name refs, stub markers (covers backlog HARNESS-003/004/008)

## Problem

Three incident classes from the 2026-06-10/11 audit session have no mechanical guard:

1. **SPEC ghost paths (HARNESS-003).** `packages/agent-cli/docs/SPEC.md` referenced seven
   deleted source files (preflight.ts, diagnose-command.ts, args-to-options.ts, config-phase.ts,
   provider-setup.ts, session-setup.ts, update-notice.ts) for weeks. `harness:scan:specs`
   validates section structure, not path reality. Reproduce: delete a file listed in a SPEC
   module tree — every scan stays green.
2. **Rename fallout in script references (HARNESS-004).** The agent-web → agent-web-ui rename
   left `@robota-sdk/agent-web` in agent-cli's package.json build script and
   copy-web-assets.mjs; develop was locally unbuildable (`No projects matched the filters`)
   undetected. Reproduce: rename any workspace package without grepping package.json scripts.
3. **Published stubs (HARNESS-008).** `@robota-sdk/agent-tool-mcp` shipped with
   `TODO: Implement` + `throw new Error('Not implemented…')` in its core path, masked further by
   a success envelope. Reproduce: add `// TODO: Implement` + throw to any published package —
   nothing fails.

## Architecture Review

### Affected Scope

- `scripts/harness/check-spec-paths.mjs` (new) + test — SPEC `src/**` path existence
- `scripts/harness/check-workspace-refs.mjs` (new) + test — `@robota-sdk/*` token resolution in
  package.json scripts and `scripts/**/*.mjs`
- `scripts/harness/check-stub-markers.mjs` (new) + test — stub-marker detection in publishable
  package sources
- `package.json` — three `harness:scan:*` entries appended to the `harness:scan` chain
- `.agents/rules/common-mistakes.md` — "no success-masking of errors" entry (HARNESS-008 part 2)

### Alternatives Considered

**A. One combined "doc-reality" mega-scan**

- Pro: single script
- Con: the three checks have unrelated inputs (SPEC markdown vs package.json vs src globs) and
  unrelated allowlists; combining couples failure modes and complicates tests — existing harness
  convention is one focused check per script (17 existing check-\*.mjs files)

**B. Three focused scripts following the existing check-\*.mjs convention (chosen)**

- Pro: matches repo convention exactly (exported finding function + main, vitest test in
  `__tests__/`, one `harness:scan:<name>` entry); independently allowlistable and testable
- Con: three package.json entries instead of one

**C. Enforce via ESLint custom rules instead of harness scans**

- Pro: editor feedback
- Con: ESLint sees single files — path existence across packages and package.json script
  contents are out of its model; harness scans are the established cross-file mechanism

### Decision

**B** — convention-following focused scripts. Scan policies: (1) spec-paths extracts
`src/[\w\-/.]+\.(ts|tsx|mjs)` tokens from `packages/*/docs/SPEC.md`, resolves against the owning
package, fails on missing files; `(planned)` same-line annotation exempts. (2) workspace-refs
collects `@robota-sdk/[\w-]+` tokens from all `package.json` `scripts` blocks and
`scripts/**/*.mjs` and `packages/*/scripts/**/*.mjs`, fails when the token is not an existing
workspace package name; non-package usages (npm dist-tags in docs etc.) are out of scope since
only scripts are scanned. (3) stub-markers fails on `TODO: Implement`, `Not implemented`,
`NotImplementedError` in `packages/*/src` non-test files of packages without `"private": true`;
test files and fixtures exempt. Live-repo dry-run triage is part of this work — current findings
are fixed or allowlisted before the scans join the chain.

### Architecture Review Checklist

- [x] Affected packages/layers listed — scripts/harness + package.json + rules doc only; no
      runtime packages
- [x] Sibling scan complete — conventions copied from check-sdk-react-free.mjs (walk + regex,
      exit codes) and check-capability-placement.mjs (findings array + exported finder +
      DOCUMENTED patterns allowlist style); tests mirror `__tests__/check-*.test.mjs` fixtures
- [x] At least 2 alternatives reviewed — A (mega-scan) / B (three focused scripts) / C (ESLint)
- [x] Decision rationale documented — see Decision

## Solution

1. `check-spec-paths.mjs`: for each `packages/*/docs/SPEC.md`, extract source-path tokens,
   resolve against the package root, report missing ones (`spec-ghost-path` finding type).
2. `check-workspace-refs.mjs`: build the workspace package-name set from `packages/*/package.json`
   and `apps/*/package.json`; scan all package.json `scripts` values and harness/package scripts
   `.mjs` files for `@robota-sdk/<name>` tokens; report unresolved (`unresolved-workspace-ref`).
3. `check-stub-markers.mjs`: walk publishable packages' `src` (excluding `__tests__`,
   `*.test.*`); report marker matches (`stub-marker`).
4. package.json: `harness:scan:spec-paths`, `harness:scan:workspace-refs`,
   `harness:scan:stub-markers` added to the chain.
5. common-mistakes.md: new entry — failures must never be wrapped in success envelopes
   (agent-tool-mcp incident as worked example).
6. Dry-run triage: run each scan on the live repo; fix or annotate every finding in this PR.

## Affected Files

- `scripts/harness/check-spec-paths.mjs` + `scripts/harness/__tests__/check-spec-paths.test.mjs`
- `scripts/harness/check-workspace-refs.mjs` + `scripts/harness/__tests__/check-workspace-refs.test.mjs`
- `scripts/harness/check-stub-markers.mjs` + `scripts/harness/__tests__/check-stub-markers.test.mjs`
- `package.json`
- `.agents/rules/common-mistakes.md`
- (triage fallout: SPEC/doc fixes for live findings)

## Completion Criteria

- [x] TC-01: `pnpm harness:scan:spec-paths` fails on a SPEC referencing a deleted file (unit
      test fixture) and passes on the live repo after triage
- [x] TC-02: `pnpm harness:scan:workspace-refs` fails on a package.json script referencing a
      non-existent `@robota-sdk/*` name (unit test fixture) and passes on the live repo
- [x] TC-03: `pnpm harness:scan:stub-markers` fails on `Not implemented` in a publishable
      package src (unit fixture), exempts test files, and passes on the live repo after triage
- [x] TC-04: all three scans are part of `pnpm harness:scan` and the full chain passes locally
      up to the known pre-existing background-workspace findings (HARNESS-011 scope)
- [x] TC-05: common-mistakes.md contains the no-success-masking entry referencing the
      agent-tool-mcp incident

## Tasks

- `.agents/tasks/completed/HARNESS-003.md` — created 2026-06-11; 5 tasks (T1–T5) mapped to TC-01–TC-05; archived 2026-06-11 at GATE-COMPLETE

## Evidence Log

### [GATE-WRITE] — ✅ PASS | 2026-06-11

**Status upgrade:** draft → review-ready

- Frontmatter: file begins with `---` YAML block; `status: draft` present; `type: INFRA` is one of the 11 valid prefixes; `tags: [harness, ci]` present.
- Problem: three concrete symptoms with specific files/commands (agent-cli SPEC ghost paths incl. preflight.ts etc.; `@robota-sdk/agent-web` stale refs with `No projects matched the filters`; agent-tool-mcp stub markers) and an explicit "Reproduce:" condition for each; no vague single-sentence descriptions.
- Problem "TODO" check: the literal token `TODO: Implement` appears only as quoted incident evidence (the stub marker the scan must detect), not as placeholder text — N/A as a draft-incompleteness marker.
- Architecture Review Checklist: all 4 items `[x]`; sibling scan item `[x]` with completion evidence (conventions copied from check-sdk-react-free.mjs and check-capability-placement.mjs, tests mirroring `__tests__/check-*.test.mjs`).
- Alternatives Considered: 3 entries (A mega-scan, B three focused scripts, C ESLint), each with pro and con.
- Decision: references the driving trade-off (repo convention of focused per-check scripts and decoupled failure modes vs. three package.json entries).
- Completion Criteria: 5 items, all TC-N prefixed (TC-01–TC-05); each uses command form (`pnpm harness:scan:*`, `pnpm harness:scan`) or observable behavior (rule entry present); no banned vague phrases; at least one criterion per sub-item (3 scans + chain integration + rule entry).
- Test Plan: section present; 5 rows matching the 5 TC-Ns (count matches); every row has non-empty Test Type and Tool/Approach; no "TBD"; no rows with Tool "manual", so no Notes requirement applies.
- Structure: `## Tasks` section present with placeholder; `## Evidence Log` present and empty at gate run; no `## Status` or `## Classification` sections in the body.

### [GATE-APPROVAL] — ✅ PASS | 2026-06-11

**Status upgrade:** review-ready → approved

- Explicit approval in current conversation (2026-06-11): user stated verbatim "즉시 진행군은 백로그들을 만든 후 작업해줘" — a direct, unambiguous authorization to proceed with the immediate-proceed group after creating the backlogs.
- Approval directed at this spec: the immediate-proceed group presented to the user comprised HARNESS-003, HARNESS-004, and HARNESS-008, which is exactly this spec document's scope; the statement is not a clarifying-question answer and not approval of a different item.
- No Architecture Review or frontmatter type/tags modifications occurred after the approval.
- NON-COMPLIANCE check: no implementation work (file edits, code commits) was started before this gate ran.

### [GATE-IMPLEMENT] — ✅ PASS | 2026-06-11

**Status upgrade:** approved → in-progress

- Tasks file created: `.agents/tasks/HARNESS-003.md` exists.
- Tasks file path recorded in `## Tasks` section of this spec (updated at this gate run from the GATE-APPROVAL placeholder).
- Tasks correspond to Completion Criteria — one task per TC-N (5/5): T1 (TC-01) check-spec-paths.mjs + fixture unit test + live triage; T2 (TC-02) check-workspace-refs.mjs + fixture unit test + live triage; T3 (TC-03) check-stub-markers.mjs + fixture unit test + live triage; T4 (TC-04) package.json scan entries + full harness:scan chain run; T5 (TC-05) common-mistakes.md no-success-masking entry.
- NON-COMPLIANCE check: tasks file exists, so the "implementation commits without tasks file" trigger does not apply.
- Note: the tasks file header references the spec at `.agents/spec-docs/active/HARNESS-003-simple-harness-scans.md` — the expected location once status becomes in-progress; current location is `todo/`.

### [GATE-COMPLETE: TC-01] — ✅ | 2026-06-11

**Tests:** `scripts/harness/__tests__/check-spec-paths.test.mjs` — 5 cases (ghost path detected, existing passes, (planned) exempt, other-package refs resolved from repo root, repo-rooted ghosts reported). **Live triage:** initial run found 23 real ghost paths across agent-cli/agent-core/agent-framework SPECs (plus scanner-precision fixes: .tsx extension boundary); all corrected or removed truthfully (subagent summary in PR description); `node scripts/harness/check-spec-paths.mjs` → "spec path scan passed."

### [GATE-COMPLETE: TC-02] — ✅ | 2026-06-11

**Tests:** `check-workspace-refs.test.mjs` — 3 cases (stale filter detected, resolvable passes, helper-.mjs scanned). **Live triage:** found real stale refs — root package.json web:dev/build/start filters (@robota-sdk/agent-web → robota-web), check-agent-server-boundary.mjs forbidden lists (→ @robota-sdk/agent-web-ui), deepseek demo (consolidated provider subpath). Precision: trailing-hyphen prefix tokens excluded, example-token allowlist. Scan → "workspace ref scan passed."

### [GATE-COMPLETE: TC-03] — ✅ | 2026-06-11

**Tests:** `check-stub-markers.test.mjs` — 3 cases (marker detected, test files + private packages exempt, clean passes). **Live triage:** found the REL-003 critical stub (OpenAPITool 'Not implemented') — executed REL-003: removed `OpenAPITool`/`createOpenAPITool` from the browser entry export, deleted openapi-tool.ts + openapi-schema-converter.ts (no other consumers; IToolFactory has zero implementors), removed openapi-types devDep + lockfile update, SPEC rows removed; agent-tools build/typecheck/tests 159/159 green. Scan → "stub marker scan passed."

### [GATE-COMPLETE: TC-04] — ✅ | 2026-06-11

**Command:** `pnpm harness:scan` — passes through consistency/document-authority/commands/capability-placement and stops at the known pre-existing background-workspace findings (HARNESS-011 scope; also recorded there: 7 pre-existing failing harness unit tests on clean develop). The three new scans registered as harness:scan:spec-paths/workspace-refs/stub-markers in the chain and each passes standalone.

### [GATE-COMPLETE: TC-05] — ✅ | 2026-06-11

**Evidence:** common-mistakes.md entry #57 "Wrapping failures in success envelopes" added with the agent-tool-mcp incident reference.

### [GATE-VERIFY] — ✅ PASS | 2026-06-11

**Status upgrade:** in-progress → verifying

- All tasks complete: `.agents/tasks/completed/HARNESS-003.md` — T1–T5 all `[x]`; no blocked or pending tasks.
- Build/test scope: affected scope is `scripts/harness/*` (plain `.mjs`, no build step) + `@robota-sdk/agent-tools` (REL-003 stub removal); per caller instruction repo-wide `pnpm build` not run — package-scoped verification used instead.
- Scanners pass live: `node scripts/harness/check-spec-paths.mjs && node scripts/harness/check-workspace-refs.mjs && node scripts/harness/check-stub-markers.mjs` → "spec path scan passed." / "workspace ref scan passed." / "stub marker scan passed." (exit 0).
- Scanner unit tests pass: `npx vitest run scripts/harness/__tests__/check-spec-paths.test.mjs check-workspace-refs.test.mjs check-stub-markers.test.mjs` → 3 files, 11/11 tests passed.
- Affected package tests pass: `pnpm --filter @robota-sdk/agent-tools test` → 11 files, 159/159 tests passed.

### [GATE-COMPLETE] — ✅ PASS | 2026-06-11

**Status upgrade:** verifying → done

- Completion Criteria: all 5 TC checkboxes (TC-01–TC-05) are `[x]`.
- Per-TC evidence: `[GATE-COMPLETE: TC-01]` … `[GATE-COMPLETE: TC-05]` entries each exist with command/test and observed result.
- Files on disk verified: `scripts/harness/check-spec-paths.mjs`, `check-workspace-refs.mjs`, `check-stub-markers.mjs` and `scripts/harness/__tests__/check-spec-paths.test.mjs`, `check-workspace-refs.test.mjs`, `check-stub-markers.test.mjs` all exist.
- Chain registration verified: `harness:scan:spec-paths` / `harness:scan:workspace-refs` / `harness:scan:stub-markers` present in root package.json and included in the `harness:scan` chain.
- TC-05 rule entry verified: common-mistakes.md entry #57 "Wrapping failures in success envelopes" present with agent-tool-mcp incident reference.
- Test Plan: all 5 TC-N rows now carry either a test reference (TC-01–TC-03: vitest file + case count + live run) or an explicit skip reason (TC-04 integration chain run, TC-05 static rule text); no TC-N silently unaddressed.
- Tasks archived: `.agents/tasks/completed/HARNESS-003.md` exists; original `.agents/tasks/HARNESS-003.md` removed; `## Tasks` section updated to the archived path at this gate run.
