Skill: Analyze Impact

What This Skill Does

Answers the question: "What will break if I implement this phase?" — before writing any code.

Performs a structured impact analysis by cross-referencing a phase's implementation plan against the current codebase. Identifies:

• Affected modules and their dependencies
• Test coverage of the areas to be changed
• Breaking change risk (public API modifications, data model changes)
• Missing prerequisites (dependencies not yet installed, config not yet set up)
• Cross-module ripple effects (changes that cascade through imports/references)
