# Doc Sync > Audit AI guidance files (CLAUDE.md, copilot-instructions.md, .github/agents/, .github/prompts/) for consistency. Use after updating any AI-facing documentation. Use when this capability is needed. - Skill: `tomevault-io/doc-sync-6` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/doc-sync-6` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/doc-sync-6/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Security - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/doc-sync-6 --- 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. --- > Source: [SAP-samples/hana-hdbext-promisfied-example](https://github.com/SAP-samples/hana-hdbext-promisfied-example) — distributed by [TomeVault](https://tomevault.io).
