# Codex CLI Bridge Skill ## Purpose This skill creates a comprehensive bridge between **Claude Code** and **OpenAI's Codex CLI**, enabling seamless interoperability through: 1. **Documentation Translation**: Converts CLAUDE.md → AGENTS.md (reference-based, no file duplication) 2. **Execution Helpers**: Python wrappers for Codex CLI commands (always uses `codex exec`) 3. **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()` - Co

About this skill
What does the codex-cli-bridge skill do?

Bridge between Claude Code and OpenAI Codex CLI - generates AGENTS.md from CLAUDE.md, provides Codex CLI execution helpers, and enables seamless interoperability between both tools

How do I install it?

Run `npx skills add alirezarezvani/claude-code-skill-factory --skill codex-cli-bridge --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From alirezarezvani/claude-code-skill-factory, a repository with 839 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
