Use this template to turn a user story into a concrete plan, skeletons, and tests.

INPUTS

• Ticket - the user story or ticket to implement
• (optional) Non-functional requirements
• (optional) Acceptance criteria
• (optional) Code - existing code context

INSTRUCTIONS

1. Extract goals, actors, and constraints from the ticket.
2. Make explicit assumptions and edge cases.
3. Produce a step-by-step plan across affected layers:
   • Frontend (web/mobile applications)
   • APIs (backend services)
   • Integrations (messaging, external services)
   • Data (databases, data warehouses, ETL)
   • Authentication/authorization systems
4. Provide key code skeletons and interface contracts.
5. Define tests to add (unit, integration, e2e).
6. Include rollout, feature flag, and observability plan.
7. Keep lines ≤80 chars.
