Codex CLI Bridge Skill

Purpose

This skill creates a comprehensive bridge between Claude Code and OpenAI's Codex CLI, enabling seamless interoperability through:

Documentation Translation: Converts CLAUDE.md → AGENTS.md (reference-based, no file duplication)
Execution Helpers: Python wrappers for Codex CLI commands (always uses codex exec)
Skill Documentation: Makes Claude Skills accessible to Codex CLI users

Key Capabilities

1. CLAUDE.md → AGENTS.md Generation

Parses CLAUDE.md and project structure
Scans .claude/skills/, .claude/agents/, documentation/ folders
Generates comprehensive AGENTS.md with file path references
Reference-based: No file duplication, only links to existing files
Documents Skills with most relevant usage method (bash scripts vs prompt references)

2. Safety Mechanism

Auto-checks Codex CLI installation (codex --version)
Auto-runs /init if CLAUDE.md missing (with user notification)
Validates authentication and environment
User-friendly error messages

3. Codex CLI Execution Helpers

exec_analysis() - Read-only analysis tasks (gpt-5, read-only sandbox)
exec_edit() - Code editing tasks (gpt-5-codex, workspace-write)
exec_with_search() - Web search-enabled tasks
resume_session() - Continue last Codex session
Always uses codex exec (never plain codex - critical for Claude Code)

4. Skill Documentation for Codex CLI

Prompt-only skills: Show how to reference in Codex prompts
Functional skills: Show how to execute Python scripts directly
Complex skills: Show both methods
Includes proper codex exec command syntax
Model selection guidance (gpt-5 vs gpt-5-codex)
