SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It reduces the risk of breaking a codebase when making changes by planning refactors with dependency and impact analysis first, then applying them with verification.

Core Features & Use Cases

  • Refactor planning with dependency-aware suggestions: Uses a graph-informed approach to propose safe refactoring steps for community-driven improvements.
  • Dead-code identification: Detects unreferenced code paths to target for removal or cleanup.
  • Rename safety previews and controlled rollout: Plans renames by previewing all affected locations, then applies changes and verifies impact.
  • Use case: When you need to rename a widely used function or remove unused modules in a large project, Refactor Safely helps you preview blast radius, apply changes, and confirm system integrity.

Quick Start

Ask the assistant to run a minimal-context refactor plan for your change request, preview any renames, apply the approved refactor, and then run change detection to verify the impact.

FAQPage Schema
How do I safely rename a widely used function without breaking dependencies?

Safe function renaming requires dependency-aware planning to preview all affected locations and blast radius before applying changes. This approach verifies system integrity post-refactor by running change detection to validate the impact on complex code graphs.

What is the best way to identify and remove dead code paths in a large project?

Dead code detection identifies unreferenced code paths for safe cleanup by analyzing dependencies across the codebase. This ensures removal targets only unused modules without breaking active flows, validating post-change effects to maintain system integrity.

How does dependency analysis help with safe code refactoring?

Dependency analysis reduces refactoring breakage by mapping complex code graphs to plan transformations and verify post-change effects. It calculates the impact radius of modifications, ensuring affected flows are checked before and after applying structural changes.

Can I preview the blast radius of a code cleanup task before applying it?

Yes, you can preview the blast radius of code cleanup tasks by running a minimal-context refactor plan. This generates dependency-aware suggestions and impact-radius checks, allowing you to approve transformations before they are applied and verified.

Does refactoring with guardrails work for suggestion-based code improvements?

Refactoring with guardrails supports suggestion-based code improvements by using a graph-informed approach to propose safe transformations. It explicitly validates post-change effects through detect_changes verification, ensuring community-driven modifications maintain system integrity.

What are the limitations of impact-radius checks during complex code refactoring?

Impact-radius checks require explicit modes for suggest, dead_code, and rename operations to function correctly, limiting automated actions to these defined scopes. Minimal-context initialization is necessary, and validation relies on detect_changes post-application to confirm affected-flow integrity.
