Validates and critiques implementation plans by seeking a second opinion from an external AI consultant.
The Plan Review via Codex skill introduces a rigorous secondary validation layer to the Claude Code workflow. By leveraging an external Codex agent, this skill allows Claude to submit its proposed implementation plans for a comprehensive audit before execution. It specifically looks for missing edge cases, architectural risks, sub-optimal logic, and potential breaking changes, ensuring that complex tasks are thoroughly vetted. This is an essential tool for high-stakes refactoring or large-scale feature additions where a single perspective might overlook critical system dependencies.
