agents-md-author

Generate cross-vendor project instruction files: AGENTS.md for Codex (and most other tools), CLAUDE.md for Claude Code, or both kept in sync. Load references/agents-md-spec.md if you need the cross-vendor convention details.

When to activate

• User asks to "write AGENTS.md", "create CLAUDE.md", or "set up project instructions for AI"
• User wants the same project doc to work in Codex, Claude Code, Cursor, or any tool that follows the AGENTS.md convention
• User mentions onboarding a new AI tool to an existing repo and wants conventions captured

Procedure

1. Detect project context (always do this first)
