SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Map the impact of changes to a Dart file by locating the paired test, direct importers, and top-level symbol references across lib/ and test/.

Core Features & Use Cases

  • Paired test discovery: mirror the source path to the corresponding test file and verify its presence.
  • Importer tracing: find files that import the target via both package-relative and relative paths.
  • Symbol reference collection: extract top-level declarations and locate external usages across the repository.
  • Use Case: when assessing the blast radius of a small change to lib/core/ssh/known_hosts.dart, generate a concise impact report.

Quick Start

Pass a Dart file path under lib/ to generate an impact report showing paired tests, importers, and symbol references.

Frequently Asked Questions about find-impact

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

FAQPage Schema
How do I map the blast radius of code changes in a Dart project?▼

To map the blast radius of code changes in a Dart project, you can analyze a source file to locate its paired tests, direct importers, and top-level symbol references. This reveals the ripple effects across lib/ and test/ directories.

How do I find all importers and call sites for a specific Dart file?▼

You can find importers and call sites for a Dart file by tracing both package-relative and relative import paths. This process enumerates direct importers and extracts top-level symbol references across the repository.

What is impact analysis and when do I need it for Flutter development?▼

Impact analysis identifies the ripple effects of modifying a source file by discovering paired tests and symbol references. You need it for Flutter development when assessing how changes to files like lib/core/ssh/known_hosts.dart affect the broader codebase.

Can I automatically discover paired test files for Dart source code?▼

Yes, you can automatically discover paired test files for Dart source code. The process mirrors the source path from the lib/ directory to the corresponding location in the test/ directory and verifies the file's presence.

Does impact analysis work with both package-relative and relative import paths?▼

Yes, impact analysis works with both package-relative and relative import paths. It enforces path normalization to accurately trace direct importers and extract top-level symbol references within your Dart project structure.
