Best agent skills for systematic debugging
Replace speculative edits with reproducible signals, hypotheses, and regression evidence.
How to choose
Matt’s diagnosing loop is particularly sharp for hard bugs and performance regressions. Addy’s recovery workflow connects root-cause work to the broader build and verification lifecycle.
Diagnosing Bugs
Runs a gated diagnosis loop from reproduction and minimization through instrumentation and regression testing.
Our take: This skill makes debugging a sequence of evidence-producing gates: reproduce, minimize, hypothesize, instrument, fix, and regression-test. It is a strong antidote to agents editing the first suspicious line and declaring victory.
Research
Investigates a technical question against primary sources and saves a cited research artifact.
Debugging and Error Recovery
Finds root causes systematically when tests, builds, or runtime behavior fail.
Browser Testing With DevTools
Verifies browser behavior through DOM, console, network, visual, and performance evidence.
