This skill provides a structured interrogation of hard bugs, guiding you from initial reproduction to a minimal, well-supported fix through a repeatable diagnostic loop.
Describe a bug you want diagnosed and let the skill guide you through reproduction, minimisation, hypothesis testing, instrumentation, and regression testing.
High-intent search queries and answers about installing and using this skill.
To debug a hard bug, you need a disciplined diagnostic loop that establishes a deterministic feedback loop to reproduce the issue, minimises the reproduction case, and forms testable hypotheses about the root cause using collected signals.
Diagnosing a performance regression requires instrumenting tests to collect signals, reducing the reproduction case to a minimal example, and verifying the regression is resolved across scenarios using evidence-driven debugging.
Creating a minimal reproduction case involves systematically reducing the steps and conditions that trigger the regression while maintaining a deterministic feedback loop to confirm the issue persists until you isolate the root cause.
Yes, instrumented tests are required for a structured debugging loop because they provide the deterministic feedback loop and collected signals necessary to form testable hypotheses and validate fixes against regressions.
Hypothesis-driven debugging works by forming testable assumptions about the root cause, adding instrumentation to collect signals, and verifying or disproving each hypothesis against evidence gathered from a minimised reproduction case.
Yes, you can guard against future regressions by establishing a clear end-to-end plan that uses instrumented tests to validate fixes and confirm the original regression is resolved across all relevant scenarios.
