Codex Second Opinion

An independent perspective from Codex via MCP. Every call starts a fresh session (no accumulated context) to ensure unbiased responses.

When to use

• User says "/codex " or "/codex" (default: review)
• User asks Codex to review, challenge, or propose alternatives
• You need a second opinion on a plan, code change, or design decision
• Two-pass review workflow needs Codex as one of the reviewers

Execution model

1. Determine the mode from the user's request (default: review)
2. Gather the artifact — for code changes run git diff, for file/artifact reviews note the file paths
3. Call mcp__codex__codex with the mode-specific developer-instructions and prompt
4. Return the raw response. Never auto-apply fixes.

Every MCP call uses these parameters
