docs-sync

A command that updates project documentation to match recent code changes. It compares changes with the main branch, updates only affected sections, and can add changelog entries from conventional commit messages.

In plain words
What is it for?
Use it after feature or code changes to update documentation sections and record relevant feature, fix, or breaking-change commits.
Why use it?
It reduces the chance that API, setup, module, or component documentation becomes outdated after development work.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docs-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/docs:sync — Living Documentation Update

Usage

/docs:sync

Behavior

Incrementally updates documentation to reflect code changes. Keeps docs in sync with the codebase as a living document. Phase 6 automatically triggers this after feature completion.

Execution Steps

  1. Diff against main. Run git diff main (or the project's default branch) to identify all changed files since the last sync.

  2. Map changed files to doc sections. For each changed file, determine which documentation section it affects:

    • New/changed API endpoint → update docs/api-reference.md
    • New/changed component → update docs/components.md
    • New/changed service/module → update docs/modules.md
    • Changed setup/config → update docs/setup.md
    • New ADR → already handled by /arch, skip
  3. Update affected docs only. For each affected section:

    • Read the current doc content
    • Read the changed source files
    • Update the doc to reflect the new state
    • Do NOT rewrite unchanged sections
  4. Generate changelog entry if conventional commits exist in the diff:

    • Parse commit messages for feat:, fix:, breaking change: prefixes
    • Append entry to docs/changelog.md with date and grouped changes
    • Format:
      ## [YYYY-MM-DD]
      ### Features
      - description (commit-hash)
      ### Fixes
      - description (commit-hash)
      
  5. Verify no stale doc references. Check that:

    • No docs reference files/functions/endpoints that no longer exist
    • No broken internal links between doc files
    • Flag any stale references found

When to Use

  • After completing a feature (Phase 6 auto-triggers this)
  • Before a release to ensure docs are current
  • Periodically during long-running development

Output

Updated documentation files in docs/. Changelog entry if conventional commits detected. List of any stale references found.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

docs-sync is a command published in the GitHub repository ngocsangyem/MeowKit (14 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 433 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
