SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you understand the full scope and potential side effects of any code change before implementation, preventing unexpected bugs, ensuring system stability, and accurately estimating development effort.

Core Features & Use Cases

  • Dependency Tracing: Identify all direct and indirect callers of modified functions, classes, or data structures across the codebase.
  • Breaking Change Detection: Determine if a proposed change will break existing functionality, API contracts, or frontend-backend interfaces.
  • Test & Documentation Impact: Pinpoint exactly which tests and documentation files will need updates due to the change.
  • Use Case: Before modifying a core data structure like SessionInfo, use this Skill to analyze its impact. It will identify all files, functions, and even frontend components that depend on SessionInfo, helping you plan for necessary updates and prevent regressions.

Quick Start

Analyze the impact of modifying the create_session() function, identifying all its callers, potential side effects, and affected tests.

Frequently Asked Questions about change-impact-analyzer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I identify what code changes will break existing functionality?▼

Breaking change detection traces how modifications to functions, classes, or data structures ripple through your codebase. Analyze the full scope of callers and dependencies before implementation to catch API contract violations, frontend-backend interface breaks, and other regressions early.

What's the best way to assess the side effects of refactoring a core data structure?▼

Map direct impact, ripple dependencies, and integration points across code, APIs, and data models. Before modifying something like a shared SessionInfo object, trace all dependent files, functions, and components to plan necessary updates and prevent cascading failures.

How do I know which tests and documentation need updates after a code change?▼

Impact analysis pinpoints the exact tests and documentation files affected by your modification. This structured assessment covers direct changes and side effects, ensuring regression readiness and accurate effort estimation before implementation begins.

Can I trace all callers of a function across my codebase to assess change risk?▼

Dependency tracing identifies all direct and indirect callers of modified functions and classes throughout your codebase. This reveals hidden dependencies and helps prevent unexpected breakage in components you didn't know relied on your code.

What should I analyze before implementing a bug fix or feature to prevent regressions?▼

Enforce a structured workflow covering direct impact, ripple impact, side effects, and integration points. This complete risk assessment maps changes across code, APIs, data models, and documentation to ensure system stability and accurate development estimates.
