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

## INPUTS

- PROJECT_CONTEXT
- USER_STORY
- (optional) NON_FUNCTIONAL_REQS
- (optional) ACCEPTANCE_CRITERIA

## INSTRUCTIONS

1. Extract goals, actors, and constraints from USER_STORY.
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.
