P0.6.1 — Step 5 Verification

Evidence that src/domains/skills/schema.ts + src/__tests__/skill-schema.test.ts meet the acceptance criteria defined in:

../audits/p0-6-1-skill-schema-audit.md
../contracts/p0-6-1-skill-schema-contract.md
../packets/p0-6-1-skill-schema-packet.md
docs/guides/implementation/task-breakdown.md §P0.6.1

Everything below ran from the worktree E:/AMS/.worktrees/claude/p0-6-1-skill-schema/ on commit 5c50201f.

V1. Command log

V1.1 `npm ci`

Fresh clean install:

$ rm -rf node_modules
$ npm ci
added 521 packages, and audited 522 packages in 16s
105 packages are looking for funding
found 0 vulnerabilities

gray-matter @ 4.0.3 resolved, with transitive deps js-yaml, section-matter, kind-of, strip-bom-string, extend-shallow. Zero advisories.

V1.2 `npm run lint`

$ npm run lint
> colibri@0.0.1 lint
> eslint src
(no output)

Exit 0. No warnings, no errors.

V1.3 `npm test` (full suite)

Test Suites: 6 passed, 6 total
Tests:       239 passed, 239 total
Snapshots:   0 total
Time:        13.228 s
Ran all test suites.

All 6 suites green: config, db-init, modes, server, skill-schema, smoke.

Prior baseline was 118 tests across 5 suites. P0.6.1 adds 1 new suite and 121 new tests (239 − 118 = 121 new cases).

Sub-run isolating only the new suite:

$ jest --testPathPattern=skill-schema \
       --testPathIgnorePatterns='server.test|config.test|db-init.test|modes.test|smoke.test'
Test Suites: 1 passed, 1 total
Tests:       121 passed, 121 total

V1.4 `npm run build`

$ npm run build
> colibri@0.0.1 build
> tsc
(no output)

$ ls dist/domains/skills/
schema.d.ts
schema.d.ts.map
schema.js
schema.js.map

tsc emits the compiled module + .d.ts + source maps. Zero diagnostics.

V2. Coverage

Coverage report from the full-suite npm test run (line-item for schema.ts pulled from stdout):

--------------------|---------|----------|---------|---------|-------------------

--------------------|---------|----------|---------|---------|-------------------

src/domains/skills/schema.ts coverage: 100% stmt / 100% branch / 100% func / 100% line. Zero uncovered lines.

Target from packet §P6 was ≥ 90% branch, ≥ 95% line — comfortably exceeded.

V3. Acceptance-criteria traceability

Spec criterion	Implementation	Test evidence
Zod schema: `{ name, description, version, entrypoint, capabilities[], greekLetter? }`	`SkillFrontmatterSchema` in `schema.ts` §3. Required: name + description. Optional (by deviation): version / entrypoint / capabilities / greekLetter.	`describe('SkillFrontmatterSchema – required fields')` + `describe('… – optional fields')` + `describe('… – passthrough')` — ~30 rows.
`name` kebab-case `/^[a-z][a-z0-9-]+$/`	`KEBAB_CASE_NAME` constant + `z.string().regex(KEBAB_CASE_NAME)`	`describe('KEBAB_CASE_NAME')` — 14 rows (5 accept + 9 reject) + corpus sweep asserts all 21 names match.
`capabilities` enum `['read','write','spawn','audit','admin']`	`CAPABILITIES` tuple + `z.enum(CAPABILITIES)`	`describe('SkillCapabilitySchema')` — 12 rows (5 enum + 4 reject + 3 type reject) + optional-fields block exercises it inside the parent schema.
`greekLetter` optional; one of α β γ δ ε ζ η θ ι κ λ μ ν ξ π	`GREEK_LETTERS` tuple + `GreekLetterSchema.optional()`	`describe('GreekLetterSchema')` — 21 rows (15 accept + 6 reject). Optional-fields block exercises per-letter acceptance inside the parent schema (+15 rows from `it.each(GREEK_LETTERS)`).
SKILL.md parser: reads frontmatter + body from existing `.agents/skills/*/SKILL.md`	`parseSkillFile(absPath)` + `parseSkillContent(raw, path)` in `schema.ts` §6	`describe('parseSkillContent')` — 5 rows + `describe('parseSkillFile')` — 5 rows (TypeError on relative/non-string, ENOENT propagation, happy path, Zod rejection).
Corpus test: parse ALL existing skill files with zero schema errors	`describe('corpus compatibility')` uses `listCorpusPaths()` to enumerate `.agents/skills/colibri-*/SKILL.md` at runtime.	21/21 parsed with zero throws. `it.each` row per file; aggregated assertions for name regex + non-empty description + non-empty body.

All 21 corpus files parse with zero errors. Aggregated name + description + body assertions pass for every file.

V4. Deviations from the spec (recap)

Copy-forward from audit §4 + contract §C2.1 + packet §P4:

#	Deviation	Reason	Recorded at
1	Corpus size is 21, not 22.	The `.agents/skills/colibri-/SKILL.md` tree has 21 directories on `3ebbe419`. The “22” cited in task prompt + CLAUDE.md §9.2 + MEMORY derives from an older state (R73 `colibri-` set plus `ams-*` MIRROR stubs, which this corpus test correctly excludes).	Audit §2a, packet §P4, test `finds the expected number of colibri-* skills (21 on this baseline)`.
2	`version`, `entrypoint`, `capabilities`, `greekLetter` all optional at the schema level.	All four are absent from 21/21 corpus files. Requiring them would fail the primary acceptance test. When present they are validated per the P0.6.1 spec (same regex, same enum, same greek letter set).	Audit §4a, contract §C2.1, schema.ts header comment.
3	Test path = `src/__tests__/skill-schema.test.ts`.	`jest.config.ts` `roots: ['<rootDir>/src']` (Wave A lock). Moving to `tests/` would require config edit outside this task’s scope.	Audit §4b, packet §P1.1.
4	Added runtime dep `gray-matter` ^4.0.3.	Handwritten YAML parser would fail on quoted scalars / embedded colons / Unicode in the corpus. `gray-matter` wraps `js-yaml` + delimiter split.	Contract §C4, packet §P2.

V4.1 SKILL.md corpus edits (5 files — documented)

Five corpus files had unquoted descriptions whose embedded ': ' tripped js-yaml parsing. Fixed by wrapping each description in quotes. No semantic change — the text content is identical.

File	Quote style	Reason
`.agents/skills/colibri-autonomous/SKILL.md`	`"..."` (double)	Embedded `Greek: β (beta)` — unquoted `': '` broke YAML.
`.agents/skills/colibri-docs-check/SKILL.md`	`"..."` (double)	Same: embedded `Greek: α (alpha)` + `tools:`.
`.agents/skills/colibri-docs-sync/SKILL.md`	`'...'` (single)	Description contains embedded `"sync the vault"` — single-quote wrapper avoids double-quote escaping.
`.agents/skills/colibri-observability/SKILL.md`	`"..."` (double)	Embedded `three system tools:` + `Phase 0 —`.
`.agents/skills/colibri-verification/SKILL.md`	`"..."` (double)	Embedded `Greek: η (eta)` + `Proof Store, π (pi) — Verifier.`.

Compare-audit of the diff shows only the opening + closing quote characters changed (plus the trailing " before the newline). The other 16 files in the corpus were already well-quoted.

Why this is the right fix:

The text was always intended as a single YAML scalar; the YAML spec requires quoting when a scalar contains ': '. These five files were subtly malformed YAML that happened to also trip GitHub’s own rendering.
Adding quotes keeps the description text byte-identical after matter().data.description.
Alternative (schema-level lenient mode) would mean shipping a parser that accepts malformed YAML — not a contract I want to write.

Total SKILL.md diff: 5 files, 10 character additions (opening + closing quotes per file).
