Planning code changes involves clarifying goals and researching existing codebase context to produce a structured plan file with phased implementation steps and explicit unit test descriptions per phase.

The best way to plan refactoring while keeping it unit-testable is generating a plan file that breaks modifications into incremental phases, explicitly defining unit tests for each phase to minimize over-coupling risk.

Turning ambiguous feature requests into implementation-ready roadmaps requires clarifying intended outcomes first, then anchoring the proposed changes in the actual current repository structure and naming conventions.

Yes, a plan file separates typed interface modifications from unrelated concerns by defining phased changes that minimize incidental complexity and avoid tangling unrelated implementation steps together.

You need a phased implementation plan for code updates when handling feature updates, refactors, or multi-phase modifications across multiple modules that must be incrementally implemented and unit-testable.
