Protocol
- Load targets in parallel — PRD, brief,
index.md + every screen file referenced, design/context-library/brand/*, design/context-library/personas/* (when present).
- Dispatch 5 reviewer subagents in parallel (single message, 5 Task calls). Each gets PRD + brief + screen file + brand + personas + own rubric. Parallel dispatch keeps context lean.
- Synthesise to
design/outputs/handoffs/PRD-{NNN}-review.md with sections 1–5 (verbatim agent output), Synthesis (Agreed / Conflicts), Priority fix list (🔴 P0 / 🟡 P1 / 🟢 P2).
- Gate — count P0s. > 0 → block. == 0 → clean, print publish prompt.
Flags
--quick — UX + A11y only (fastest; iteration).--full — all 5 (default; required before handoff).
Do Not
- Collapse reviewer output. Verbatim agent responses in synthesis — trust accrues.
- Call handoff “clean” with open P0s, even if user presses. Gate is on artifact, not conversation.
- Fire fewer than 5 agents when
--full is the mode — parallel dispatch is the point.
