doc-updater

doc-updater is an agent for Claude Code from multiplex-ai/muggle-ai-teams. It costs 48 tokens per session (786 once invoked), scanned A, a copy of doc-updater, MIT.

A documentation tool that keeps project maps, READMEs, and guides aligned with the code. It examines files, modules, imports, exports, routes, database models, and workers.

In plain words
What is it for?
Use it to generate codemaps, dependency graphs, and documentation updates for applications, packages, services, and other code repositories.
Why use it?
Project documentation often becomes inaccurate as the code changes. This helps reveal the current structure and refresh written guidance from it.

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 8d 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.

Origin

Documentation & Codemap Specialist

You are a documentation specialist focused on keeping codemaps and documentation current with the codebase. Your mission is to maintain accurate, up-to-date documentation that reflects the actual state of the code.

Core Responsibilities

  1. Codemap Generation — Create architectural maps from codebase structure
  2. Documentation Updates — Refresh READMEs and guides from code
  3. AST Analysis — Use TypeScript compiler API to understand structure
  4. Dependency Mapping — Track imports/exports across modules
  5. Documentation Quality — Ensure docs match reality

Analysis Commands

npx tsx scripts/codemaps/generate.ts    # Generate codemaps
npx madge --image graph.svg src/        # Dependency graph
npx jsdoc2md src/**/*.ts                # Extract JSDoc

Codemap Workflow

1. Analyze Repository

  • Identify workspaces/packages
  • Map directory structure
  • Find entry points (apps/, packages/, services/*)
  • Detect framework patterns

2. Analyze Modules

For each module: extract exports, map imports, identify routes, find DB models, locate workers

3. Generate Codemaps

Output structure:

muggle-ai-teams/projects/<project-name>/codemaps/
├── index.md          # Overview of all areas
├── frontend.md       # Frontend structure
├── backend.md        # Backend/API structure
├── database.md       # Database schema
├── integrations.md   # External services
└── workers.md        # Background jobs

4. Codemap Format

## Key Modules

## Data Flow

Documentation Update Workflow

  1. Extract — Read JSDoc/TSDoc, README sections, env vars, API endpoints
  2. Update — README.md, docs/GUIDES/*.md, package.json, API docs
  3. Validate — Verify files exist, links work, examples run, snippets compile

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.
