What is the main purpose of the Codex CLI Bridge?

It enables seamless interoperability between Claude Code and OpenAI Codex CLI by syncing documentation and providing safe execution helpers for cross-tool workflows.

Does this skill duplicate files when generating AGENTS.md?

No, it uses a reference-based approach that creates links to existing files like CLAUDE.md to maintain a single source of truth without duplicating content.

Can I use this for both analysis and code editing?

Yes, the skill includes specific wrappers for read-only analysis tasks using gpt-5 and workspace-write editing tasks using the gpt-5-codex model.

Why does the skill insist on using 'codex exec'?

The 'codex exec' command is required for compatibility within the Claude Code environment to prevent 'stdout is not a terminal' errors that occur with the standard codex command.

What happens if my project is missing a CLAUDE.md file?

The skill includes a safety mechanism that automatically detects missing documentation and offers to run the /init command to set up your project environment.

Developer Tools

Synchronizes Claude Code and OpenAI Codex CLI workflows by automating documentation translation and providing secure execution wrappers.

The Codex CLI Bridge is a specialized skill designed for developers utilizing both Claude Code and OpenAI's Codex CLI. It bridges the gap between these environments by automatically generating AGENTS.md from existing CLAUDE.md files, ensuring documentation parity without file duplication. The skill provides high-level Python wrappers for various Codex tasks—such as code analysis, editing, and web search—while enforcing safety mechanisms like environment validation and the mandatory use of the 'codex exec' command to prevent terminal interface errors. It is an essential tool for teams looking to leverage the strengths of both AI coding agents in a unified, cross-tool workflow.
