Impact Analyzer

When to Use

Trigger this skill when the user:

• 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 "what will break if I change X"
• 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

• File path: /sourceatlas:impact "src/api/users.ts"
• API endpoint: /sourceatlas:impact "api /api/users/{id}"
• 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

• "What happens if I change this file?"
• "What depends on UserService?"
• "Is it safe to modify the authentication module?"
• "Impact of changing the User model"
