How is the impact radius calculated?

The impact radius is calculated by counting the unique files in the transitive dependency tree that import the target file or its importers.

What is the difference between MODIFY, DELETE, and RENAME?

MODIFY updates content, DELETE removes the file, and RENAME changes the filename. All three trigger dependency checks to ensure importers are updated or accounted for.

Can I use this to find which tests to run?

Yes, you can use the `identify_test_coverage` tool to find the specific test files that exercise the logic of your target file.

More Details Connect to Claude

The File Change Impact Assessor is a deterministic tool designed to prevent regressions by quantifying the 'blast radius' of any file modification. By parsing import statements and building a dependency graph, it identifies exactly which files are transitively affected when a target is modified, deleted, or renamed. Use analyze_impact to determine the risk level and affected files, get_dependency_graph to visualize connections, and identify_test_coverage to pinpoint the specific tests required to validate a change.
