Generate Agents Md

Generate AGENTS.md

Extract operational content from CLAUDE.md to create a universal AGENTS.md file for cross-tool compatibility with Cursor, Codex, Copilot, and other AI agents.

Overview

This workflow extracts the Operations and Boundaries sections from CLAUDE.md to generate a minimal, universal AGENTS.md file that works across 20+ AI coding tools.

Why generate instead of symlink?

• Symlinks may not work on all systems (Windows)
• AGENTS.md can be customized without affecting CLAUDE.md
• Some teams prefer explicit files over symlinks
• Allows for tool-specific adjustments

When to Use

✅ Use this workflow when:

• Team uses multiple AI tools (Cursor + Claude Code, Codex + Claude)
• Deploying to systems where symlinks don't work well
• Want a standalone AGENTS.md for open-source projects
• Need to customize AGENTS.md separately from CLAUDE.md

❌ Use symlink instead when:

• Only team uses Claude Code and one other tool
• System supports symlinks reliably
• Want single source of truth with no drift

Symlink command: ln -s CLAUDE.md AGENTS.md

Process

Step 1: Analyze CLAUDE.md

AI reads CLAUDE.md and identifies:

1. Operations section - Setup, Testing, Build, Code Style commands
2. Boundaries section - Protected files, never commit, ask before
3. Project-specific customizations (if any)

Step 2: Generate AGENTS.md

Create AGENTS.md with AGENTS.md standard structure:

# AGENTS.md

> Auto-generated from CLAUDE.md. For full methodology, see CLAUDE.md.
> Last generated: [DATE]

Step 3: Verify and Save

1. AI presents generated AGENTS.md for review
2. User approves or requests changes
3. Save to project root: ./AGENTS.md

Boundaries

Do Not Modify

• Lock files (package-lock.json, yarn.lock, Cargo.lock)
• Environment files (.env, .env.local)
• CI/CD configurations (.github/workflows/)
• Applied database migrations

Never Commit

• Secrets, API keys, credentials
• .env files (use .env.example)
• Build artifacts, node_modules/, target/

Ask Before Changing

• Authentication/authorization logic
• Database schemas
• Public API contracts
• Major dependencies

## Customization Guide

### Project-Specific Adjustments

When generating AGENTS.md, AI should:

1. **Detect tech stack** from:
   - `package.json` (Node.js)
   - `requirements.txt` / `pyproject.toml` (Python)
   - `go.mod` (Go)
   - `Cargo.toml` (Rust)

2. **Extract actual commands** from:
   - `package.json` scripts
   - `Makefile`
   - `justfile`
   - CI/CD workflows

3. **Include project-specific boundaries** from:
   - `CLAUDE.md` (if exists)
   - Existing `.gitignore` patterns

### Monorepo Support

For monorepos, generate nested AGENTS.md files:

project/ ├── AGENTS.md # Root-level (general) ├── CLAUDE.md # Full methodology ├── packages/ │ ├── api/ │ │ └── AGENTS.md # API-specific commands │ └── web/ │ └── AGENTS.md # Web-specific commands

Each nested AGENTS.md should:
- Focus on that package's commands
- Reference root AGENTS.md for general guidelines
- Include package-specific boundaries

---

## Maintenance

### When to Regenerate

Regenerate AGENTS.md when:
- CLAUDE.md Operations section changes
- New build/test commands added
- Project structure changes significantly
- Tech stack updated

### Keeping in Sync

**Option A: Manual regeneration**
```bash
# Load this skill periodically when CLAUDE.md changes
.claude/skills/generate-agents-md/SKILL.md

Option B: Pre-commit hook

# .husky/pre-commit or similar
# Check if CLAUDE.md changed, regenerate AGENTS.md

Option C: CI/CD check

# .github/workflows/check-agents-md.yml
- name: Verify AGENTS.md is up to date
  run: |
    # Compare timestamps or checksums

Integration with CLAUDE.md

How They Work Together

Reading Priority (Claude Code)

1. Claude Code reads CLAUDE.md (primary)
2. If CLAUDE.md not found, reads AGENTS.md (fallback)
3. Both can coexist (different purposes)

For Other Tools

Most tools (Cursor, Codex, Copilot) read:

1. AGENTS.md (primary)
2. May also read CLAUDE.md if present

Troubleshooting

Issue: AGENTS.md and CLAUDE.md out of sync

Solution: Regenerate AGENTS.md or set up sync mechanism

Issue: Other tools not reading AGENTS.md

Solution: Ensure file is in project root, named exactly AGENTS.md

Issue: Symlink not working

Solution: Use this skill to generate actual file instead

Issue: Need different commands for different tools

Solution: Generate AGENTS.md with common subset, add tool-specific comments

Remember: AGENTS.md is for operational commands. Keep it minimal and actionable. Full methodology stays in CLAUDE.md.
