PlanX

PlanX turns an AI coding agent's plan into a stored, versioned artifact you can read, annotate and approve outside the agent. It installs a skill into Codex and Claude Code, captures what they plan, and gives you a terminal review over the result. Approval refers to an exact version, and the version is what gets built.

PLAN → REVIEW → REVISE → EXECUTE → RESUME
