Write Agent Brief

Write the contract an implementation agent can work from later.

Prefer behavior and interfaces over file paths. File paths go stale; contracts survive.

Process

1. Read the current context and any task packet.
2. Separate current behavior from desired behavior.
3. Name key interfaces, data shapes, commands, and user-visible behavior.
4. State acceptance criteria as independent checks.
5. State out of scope explicitly.
6. Add human review or approval needs.
