Delegates complex development tasks to OpenAI GPT models via the Codex or Agent command-line interfaces.
The Codex CLI skill enables Claude to hand off specific tasks to OpenAI's GPT models when unique reasoning strengths or specific model capabilities are required. It automatically detects the available environment (preferring the native codex binary with a fallback to the agent CLI), manages execution timeouts, and provides intelligent retry logic for rate limits or system failures. This skill is ideal for users who need to leverage external AI reasoning within their Claude-based workflow, offering a specialized 'plan-only' mode for safe architectural analysis and seamless integration of high-reasoning model outputs.
