Slice an approved design pack (blueprint + baseline) into self-contained work packets that any coding agent — Claude, Codex, Cursor, Grok, or a local model — can execute without access to this conversation, and generate fix briefs from gate reports. Use when the user says "create the briefs", "slice the work", "hand this to codex", "work packets", after a design baseline is approved, when an approved director-07-feature-impact map needs implementation, or when a fidelity or release gate report lists deviations that need fixing.
