Cursor frontmatter descriptions + +The Cursor copies have shorter, terser descriptions that differ from the canonical source: + +```yaml +# Source (gitnexus/skills/gitnexus-debugging.md) +description: "Use when the user is debugging a bug, tracing an error, ..." + +# Cursor (gitnexus-cursor-integration/skills/gitnexus-debugging/SKILL.md) +description: Trace bugs through call chains using knowledge graph +``` + +This applies to all 5 Cursor skills. The descriptions are not just truncated — they are independently rewritten. + +### 2. `.claude/gitnexus-cli` content omission + +The `.claude` copy of the CLI skill is missing a content sentence present in the source: + +```diff +- **When to run:** First time in a project, after major code changes, or when +- `gitnexus://repo/{name}/context` reports the index is stale.

This is cosmetic but means byte-level comparison fails, complicating any naive diff-based drift detection. + +### 4. Cursor missing 2 of 7 skills + +`gitnexus-cli` and `gitnexus-guide` are absent from the Cursor integration. There is no manifest, config, or documentation explaining whether this is intentional. + +### 5. `SKILL_NAMES` hardcoded list missing `gitnexus-pr-review` + +The runtime installer in `setup.ts` uses a hardcoded array of 6 skill names. `gitnexus-pr-review` is excluded, meaning it is never installed to user machines even though it exists in all 4 repository locations. + +--- + +## Strategy Analysis + +Four approaches were evaluated across two independent analysis sessions: + +### Option A: Build-time sync script ✅ Recommended + +A `scripts/sync-skills.ts` script reads from the canonical source (`gitnexus/skills/`) and generates derived copies. + +| Dimension | Assessment | +|-----------|-----------| +| Can drift silently? | No (CI catches it) | +| Developer experience | Good — `npm run sync:skills` | +| Platform compatibility | Excellent (Node.js) | +| Complexity | Low–medium | +| Handles extras (mcp.json) | Yes — only overwrites `SKILL.md` | +| Handles subsets | Yes — via explicit allowlist per target | + +### Option B: Symlinks ❌ Ruled out + +| Dimension | Assessment | +|-----------|-----------| +| npm publish | **Breaks** — npm silently drops symlinked files ([npm/cli#6746](https://github.com/npm/cli/issues/6746)) | +| Windows | Requires Developer Mode | +| mcp.json companions | Cannot symlink a file into a directory that also needs non-symlinked files | + +### Option C: CI drift-detection only ⚠️ Insufficient alone + +Detects drift but does not help developers fix it.

Must be paired with CI. + +### Industry context + +No widely-adopted npm package exists for syncing arbitrary content files within a monorepo.

All 839 existing unit tests remain green. | +| 2026-03-07 | Phase 3 complete | Implemented `planSync()` in `gitnexus/src/sync-skills.ts`. TDD green phase: all 35 sync-skills tests pass. Full unit suite green (874 tests). Implementation covers: source discovery (gitnexus-* pattern filtering), target allowlist filtering with deduplication, YAML frontmatter stripping, generated header prepend, trailing newline normalization, path generation (flat .md → {name}/SKILL.md), idempotency via content comparison (write/skip), input validation (null/undefined skills array, missing source skills), and graceful handling of malformed frontmatter. | +| 2026-03-07 | Phase 4 complete | Created `skills.manifest.json` in all 3 target directories (`.claude/skills/gitnexus/`, `gitnexus-claude-plugin/skills/`, `gitnexus-cursor-integration/skills/`) — all listing all 7 skills. Created executable sync script `gitnexus/scripts/sync-skills.ts` with manifest loading, `--dry-run` support, and filesystem write execution. Added `npm run sync:skills` and `npm run sync:skills:check` scripts. Ran sync to regenerate all 21 derived SKILL.md files with AUTO-GENERATED headers. Verified idempotency (second run = 0 writes). Companion `mcp.json` files untouched. | +| 2026-03-07 | Phase 5 complete | Added `skill-sync-check` job to `.github/workflows/ci.yml`. Runs `npm run sync:skills` then `git diff --exit-code` on all 3 target directories. PRs with stale derived SKILL.md files will fail CI. | +| 2026-03-07 | Phase 6 complete | Superseded analysis docs already removed in prior commit. Ran `npm run sync:skills` — all 21 files up-to-date, `git diff --exit-code` clean. Full unit suite green (874 tests, 38 files). All 6 phases complete. | + +--- + +*This is a living document.
