What problem does it solve?
Claude Code users often hit limits doing large refactors and line-by-line review alone and lack a first-class way to hand those jobs to Codex without leaving the agent.
Who is it for?
Solo builders on Claude Code who already run Codex CLI and want agent-driven delegation for review and refactor batches.
Skip if: Teams with no OpenAI Codex access, or anyone who only needs generic chat without a second CLI runtime.
What do I get? / Deliverables
After you add the marketplace, Claude can forward suitable tasks to Codex CLI so review and refactor work runs on OpenAI’s tooling while you stay in one Claude Code flow.
- Registered skill-codex plugin inside Claude Code
- Callable delegation path from Claude prompts to Codex CLI for analysis and edits

Journey fit
The plugin’s stated focus is code analysis, refactoring, and automated code review—work that belongs in the shipping-quality gate before release. Review is the canonical shelf because delegation targets review-style tasks rather than greenfield implementation or distribution.
How it compares
Claude Code marketplace bridge to Codex CLI, not a standalone review skill or MCP server catalog.
