What
When writing a plan in plan mode, Claude is now instructed to begin with a Context section explaining why the change is being made before listing implementation steps.
Details
- The Context section must describe: the problem or need being addressed, what prompted the change, and the intended outcome.
- This addition helps reviewers understand the motivation before reading the technical steps.
- The rest of the plan format is unchanged (recommended approach, file paths, utilities to reuse, verification steps).
