Smart Test Selection Skill

Purpose

Optimizes test execution by intelligently selecting which tests to run based on code changes. Instead of running the full test suite every time, this skill:

1. Maps code changes to affected test files using import dependency analysis
2. Provides tiered testing strategies for different feedback loop needs
3. Tracks test reliability to prioritize stable tests in fast runs

When I Activate

I automatically load when you mention:

• "run affected tests" or "run impacted tests"
• "smart test" or "intelligent testing"
• "which tests to run" or "test selection"
• "fast tests" or "quick tests"
• "tests for changes" or "tests for this PR"
