Use when operating as the Pi architecture/design governor for the stores substrate, or when asking Pi for design review, priority coherence, contract ratification advice, or architectural approval over agent-comm.
Use when operating as the Claude Code engine controller for the stores substrate: driving tasks, daemon/worktrees, codex/rebase loops, and multi-agent coordination.
Use for the temporary front-of-engine queue-curation role in stores: triages observations/intake/tasks, deduplicates stale/noisy rows, drafts priority recommendations, and delegates backlog analysis to subagents without implementing code.
Use during wind-down when acting as engine-controller and preparing the next engine-controller agent handover.
Use for the session-scoped read-only codex sensor role in stores: watches in_review tasks, rebases review worktrees, runs codex, and posts structured review digests over agent-comm without writing substrate state or code.
Use during wind-down when acting as reviewer-runner and handing off codex/review state to the next reviewer-runner.
Use during wind-down when acting as Pi architect and handing off architectural state, priorities, and pending decisions.
Use when Blake says context is high, asks to wind down, pause/clear the engine, prepare handover, or end a multi-agent stores session cleanly. Coordinates substrate-agent/reviewer-runner feedback, updates SOP skills/docs, and produces next-session handover…
