Cleans and interprets raw PHPUnit CI logs into a compact, AI-friendly failure report. Use this skill whenever the user pastes or uploads a PHPUnit log, GitHub Actions test output, CI test results, or asks to interpret/summarize/analyze failing tests. Trigger even if the user says things like "here's my test output", "tests are failing", "can you look at my PHPUnit log", or pastes a block of text that contains PHPUnit output. Always use this skill before attempting to diagnose failures.
