doc-sync

Compare key facts across all AI guidance files and flag mismatches. ## Files to Check - `CLAUDE.md` (primary, source of truth) - `.github/copilot-instructions.md` - `.github/agents/parity-maintainer.agent.md` - `.github/prompts/add-parity-method.prompt.md` - `.github/prompts/release-checklist.prompt.md` - `.claude/agents/parity-reviewer.md` - `.claude/skills/parity-sync/SKILL.md` - `.claude/skills/release-check/SKILL.md` ## Facts to Verify Across Files 1. **Package count** — Three packages: `hdb/`, `hdbext/`, `hdbhelper/`. Any file that mentions "two packages" is stale. 2. **Node.js engine constraints** — hdb: `^20 || ^22 || ^24`, hdbext: `>=18.18.0`. Cross-check against `package.json`. 3. **Go version** — Must match `go.mod` directive. Cross-check against `go.mod`. 4. **Known API divergences** — `loadProcedurePromisified`, `callProcedurePromisified`, hdb-only methods (`destroyClient`, `validateClient`, `fetchSPMetadata`, `setSchema`). Ensure all files that reference these agree. 5. **Commands** — `npm test`, `npm run types`, `go test`, `go build`, `go vet`. Verify referenced commands match `package.json` scripts and actual usage. 6. **CI matrix** — Node versions and Go version in `.github/workflows/ci.yml` should be consistent with documented constraints. ## Output Report a table: | File | Status | Issues | |------|--------|--------| | ... | In sync / Drifted | specific mismatch | Then list recommended fixes with exact diffs.
