Grill Me

Grill Me

Phase 2b gate. No implementation until plan survive grilling.

Step 1: Interview

Walk every branch of decision tree. Resolve dependencies one-by-one. Each question, give recommended answer. One at time.

If question answerable by exploring codebase, explore first.

Step 2: Three-Hat Fan-Out (parallel)

Once user present coherent plan, spawn three reviewers in parallel (single message, multiple Agent tool calls):

• plan-product-hat: persona, pain, success metric, scope, reversibility, TTV
• plan-engineering-hat: architecture, error paths, perf, security, test strategy, rollback
• plan-design-hat: flow, a11y, copy, visual consistency, states (empty/loading/error)

Each emit {reviewer, status, findings[], must_answer[]} per findings-schema.md.

Step 3: Merge

Consolidate all must_answer questions into single list, deduped. Surface to user. User answer each. Plan updated inline.

Any reviewer return status: BLOCKED -> plan no advance until blocking finding addressed or user override.

Step 4: Approve

All hats return APPROVED or user override specific findings -> plan approved -> Phase 3 (Implement).

Skip Gate

Skip three-hat fan-out only if:

• Trivial bug fix, AND
• <3 tasks in plan, AND
• No architectural / product / UX decisions

Else, fan-out mandatory. [ETHOS: Grill Before Build]
