Create Test Plan

Analyze what changed and generate a comprehensive test plan covering four escalating levels of testing depth.

Step 1: Determine Scope

Resolve scope using the first match:

1. User-specified — the user says what to test. Use that.

4. App-level discovery — fresh context with no prior work. Examine the project (entry points, routes, commands, README) to identify the app's core user-facing flows.

Step 2: Analyze the Change

After identifying scope, read the actual code in depth to understand:
