codex
By robbyt
Integrate OpenAI Codex CLI via local MCP server in Claude to analyze codebases for architecture overviews, dependencies, onboarding, and tech debt; review git diffs for bugs, security vulnerabilities, style, and performance issues; and critique implementation plans for gaps, risks, and alternatives.

Component Details
Skills (3)
Codebase analysis using Codex CLI with read-only sandbox. Trigger when user needs architecture overview ("analyze this codebase with Codex", "have Codex map dependencies"), onboarding to unfamiliar code, understanding legacy systems, or identifying technical debt.
Get Codex's code review of git changes after Claude makes edits. Trigger when user wants a second opinion on code changes ("have Codex review my changes", "get code review from Codex", "review this diff with Codex"), or as a final check before committing.
Get Codex's review of Claude's implementation plans. Trigger when user wants a second opinion on a plan ("have Codex review this plan", "get second opinion from Codex", "critique this plan with Codex"), or after Claude creates a plan file that needs validation before implementation.
