# Codex Framework

> Reference knowledge for OpenAI Codex CLI compatibility — how Codex discovers AGENTS.md instructions and .agents/skills so a Forge (Claude Code) project can interoperate with Codex without duplicating agent definitions. Use when a user asks to "add Codex support", make the repo "work with Codex CLI" / "work with both Claude Code and Codex", share governance state between the two tools, or when comparing AGENTS.md vs CLAUDE.md discovery. REFERENCE ONLY — never auto-creates AGENTS.md or .agents/ files.
