Enables Claude Code to delegate tasks to OpenAI's Codex CLI (GPT-5.4) with structured execution traces, parallel execution, session persistence, and adversarial code review.
Enables Claude to offload mechanical, output-heavy tasks like boilerplate, type generation, and summarization to OpenAI while keeping reasoning in-context.
Enables Codex to delegate tasks to interactive Claude Code sessions as role-controlled subagents for exploration, code review, and implementation, using the existing Claude Code installation on macOS.
