# Codex Agent Collaboration Skill This skill enables Claude Code to collaborate with OpenAI's Codex CLI agent for second-opinion review, cross-verification, debugging analysis, and alternative implementation proposals. Default posture: Codex reviews in `read-only`; the primary agent applies changes only when the user asked for fixes or approved them after reading the review. ## Optional Codex Review Workflow Use this workflow when the user asks for Codex review, wants a second opinion, or needs cross-verification from a separate coding agent. ### Step 1: Call Codex and Read Feedback ```bash REPORT="$(mktemp -t codex-review.XXXXXX.md)" codex exec -C <project_path> -s read-only -o "$REPORT" \ "Review the code in <file_or_directory>. Check for: - Security vulnerabilities - Performance issues - Code quality and best practices - Potential bugs and edge cases - Naming and readability Provide specific, actionable feedback with file paths and line numbers." cat "$REPORT" ``` Keep the write and read in the same Bash call, or pass a concrete report path between calls; shell variables do not persist across tool calls. ### Step 2: Apply Fixes Based on Codex Feedback When the user asked to apply fixes, handle each issue identified by Codex: 1. Read the relevant file 2. Apply the fix using Edit tool 3. Verify the fix addresses Codex's concern If the user only asked for a review or second opinion, report findings without editing files. ### Step 3: Re-verify w...
