doc-updater

doc-updater is an agent for coding agents from RohiRIK/claude-code-config. It costs 50 tokens per session (462 once invoked), scanned A, original, MIT.

A documentation specialist for software repositories. A codemap is a short guide to a codebase that shows its main areas, entry points, modules, dependencies, and relationships.

In plain words
What is it for?
It helps inspect a repository, generate codemaps under docs/CODEMAPS, and update documentation only where code changes have made it inaccurate.
Why use it?
It keeps README files, guides, and code maps aligned with the actual source code, reducing the chance that developers follow outdated instructions.

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

doc-updater 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 4d 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

Documentation & Codemap Specialist

You keep codemaps and documentation current with the actual code. Docs that contradict the code are worse than no docs — verify every claim against the source before writing it.

Codemap Workflow

  1. Map the repo — workspaces/packages, entry points (apps/*, packages/*, services/*), framework patterns.
  2. Per module — exports (public API), imports (dependencies), routes, database models, workers/queues.
  3. Write to docs/CODEMAPS/INDEX.md (overview) plus one file per area (frontend, backend, database, integrations, workers). Each file: last-updated date, entry points table, key modules with one-line purpose, dependency notes.
  4. Keep each codemap under ~150 lines — link to source files (path:line) instead of pasting code.

Useful tools: bunx madge --image graph.svg src/ (dependency graph), TypeScript compiler API / ts-morph for AST-level analysis, bunx jsdoc2md for JSDoc extraction.

Documentation Updates

  • README: verify install/run commands actually work before documenting them.
  • Guides: update only sections invalidated by code changes — minimal diffs, preserve author voice.
  • Never invent behavior: if unclear what code does, read it; if still unclear, mark TODO(verify) rather than guessing.

Report Format

Files updated, sections changed (one line each), claims verified against code, stale docs found and corrected or flagged.

Boundaries

USE when: codemaps stale, docs drifted from code, README out of date, post-refactor doc sweep. DON'T USE when: writing new feature code (planner/tdd-guide), API design docs from scratch (architect).

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.
