Need to Make a Decision
Challenge a proposed design from every critical angle and turn weak spots into explicit fixes, owners, evidence requests, or decision conditions.

Use this when
A technical direction is approaching approval, implementation, procurement, or an architectural commitment. The design affects important data, security boundaries, production reliability, migration work, or long-term maintenance.
You'll need
- Design summary
- Decision stage
- Requirements and constraints
- System context
- Data and security context
- Operability expectations
- Migration plan
- Alternatives and evidence
You'll get
- The decision envelope stated with measurable acceptance criteria
- Every material assumption classified by evidence and impact
- Credible failure modes paired with detection, containment, and recovery
- Security, data, operability, and dependency gaps classified
- Migration, rollback, and points of no return documented
- Long-term maintenance costs and ownership concerns recorded

Sample input
Design: An event-driven order pipeline using a transactional outbox, managed queue, and separate inventory, payment, and notification consumers. Decision stage: Approval pending. Targets: 2,000 orders per minute, no accepted-order loss, no duplicate charges, and normal processing within 30 seconds. Key gaps: The prototype reached 1,500 orders per minute. Duplicate delivery, dependency degradation, deletion propagation, poison messages, backfill, and rollback haven't been tested.
