What Doc Updater by affaan-m is

Doc Updater by affaan-m is a subagent published in the affaan-m/ECC repository on GitHub, which has about 268k stars. The repository describes itself as: “The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Doc Updater and get back a compact result.

How to install Doc Updater by affaan-m

Claude Code

  1. Download doc-updater.md from the repository.
  2. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
  3. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

  1. Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
  2. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Inside the source file

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

Key Principles

  1. Single Source of Truth — Generate from code, don't manually write
  2. Freshness Timestamps — Always include last updated date
  3. Token Efficiency — Keep codemaps under 500 lines each
  4. Actionable — Include setup commands that actually work
  5. Cross-reference — Link related documentation

Quality Checklist

  • Codemaps generated from actual code
  • All file paths verified to exist
  • Code examples compile/run
  • Links tested
  • Freshness timestamps updated
  • No obsolete references

When to Update

ALWAYS: New major features, API route changes, dependencies added/removed, architecture changes, setup process modified.

OPTIONAL: Minor bug fixes, cosmetic changes, internal refactoring.

Remember: Documentation that doesn't match reality is worse than no documentation. Always generate from the source of truth.

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
