- Is about to modify code and wants to know the impact
- Asks what depends on a file or component
- Wants to understand breaking change risks

- Asks "is it safe to modify this"

## Instructions

1. Identify the file, component, or API the user wants to change
2. Run `/sourceatlas:impact "<target>"` with the target
3. Returns dependency analysis, risk assessment, and migration checklist

## Target Formats

- Component: `/sourceatlas:impact "UserService"`
- Model: `/sourceatlas:impact "User model"`

## What User Gets

- Impact summary (backend, frontend, test files affected)
- Risk level assessment (red/yellow/green)
- Breaking change risks
- Migration checklist
- Test coverage gaps

## Example Triggers
