doc-updater

doc-updater is an agent for coding agents from affaan-m/ECC. It costs 53 tokens per session (767 once invoked), scanned A, original, MIT.

A documentation and codemap agent that derives architecture notes and dependency maps from a codebase. A codemap is a set of documents showing the project's folders, modules, entry points, routes, data models, and relationships.

In plain words
What is it for?
Use it to generate or refresh docs/CODEMAPS, update READMEs and guides, inspect TypeScript structure, and map imports, exports, routes, database models, and workers.
Why use it?
It helps prevent READMEs and technical guides from becoming inaccurate as the code changes.

About the project

ECC is a toolkit that organizes and improves how coding agents work through skills, memory, security checks, research practices, and related extensions. It is for developers using agents such as Claude Code, Codex, OpenCode, and Cursor.

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 5d 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.

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:

docs/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

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.
