codex-loop

Autonomous Codex workflow that implements codex-loop/prd.json with one fresh Codex subagent per story. Use when the user asks to run Codex Loop, run the loop, work through a PRD, process prd.json, implement all stories, iterate through user stories autonomously, or complete a feature broken into PRD stories. Sequential mode is the default. Use parallel wave mode only when the user explicitly asks to run the loop in parallel, in tandem, as waves, or to fan out; parallel mode runs independent stories whose dependsOn entries are satisfied in isolated git worktrees with a merge and verification barrier between waves.
