User-invocable skill for when Claude is stuck mid-task. Claude narrates its own blocker to Codex, gets back a structured diagnosis + concrete next steps, applies them, verifies, and loops up to N rounds until the problem is resolved or the loop detects it's spinning. Read-only — Codex advises, Claude edits.
Explore ideas before implementation. Turn vague requests into fully formed designs and specs through collaborative dialogue. Use before any creative work — creating features, building components, adding functionality, or modifying behavior. Proactively suggest when the user jumps straight to code without a design.
Write comprehensive implementation plans from specs or requirements. Use when you have a spec or requirements for a multi-step task, before touching code. Plans are bite-sized, TDD-first, with exact file paths and complete code in every step.
Internal helper contract for calling the codex-companion runtime from the codex-rescue subagent. Not user-invocable.
Internal contract for presenting Codex output back to the user. Referenced by dual-review (structured findings) and rescue (task output). Not user-invocable.
Sequential Claude-Codex review loop for specs and plans with structured JSON findings. Embedded in brainstorming and writing-plans for automatic Codex review after self-review. Also user-invocable for manual ad-hoc review. Max 3 rounds default, early exit if clean.
Internal guidance for composing Codex / GPT-5.4 prompts used by rescue and dual-review. Covers XML block structure, grounding, output contracts, verification loops. Not user-invocable.
Delegate a substantial investigation, diagnosis, or implementation task to Codex via the codex-rescue subagent. Use when Claude is stuck, wants a second implementation pass, needs deeper root-cause investigation, or should offload long-running work. Supports background execution, model selection, and thread resume.
