Plan Architecture

Use when

• a feature spans multiple files or systems
• APIs, persistence, or async flows are involved
• execution order and risk need to be locked down

Workflow

1. Trace impacted components and interfaces.
2. Define the data flow and failure modes.
3. Specify API, storage, and validation boundaries.
4. Break the work into dependency-aware steps.
5. Attach tests and verification to each phase.
