diagnose

A structured debugging loop guides hypothesis-driven investigation through phases: reproduce, minimise, hypothesise, instrument, fix, and regression-test, ensuring reliable signal collection for root cause identification.

You reproduce and minimise a hard bug by establishing a fast, deterministic feedback loop that captures traces and instruments code, enabling repeatable experimentation and reliable signal collection for root cause triage.

Yes, you can use this approach for performance regressions in CI environments; it guides hypothesis-driven investigation, instruments code to collect traces, and verifies fixes with regression tests across local and CI setups.

Yes, diagnosing hard bugs requires the ability to run tests, capture traces, and instrument code to produce reliable signals for debugging and to verify fixes through regression-testing.

The best way to triage an intermittent or failing bug is to use a disciplined diagnosis loop from reproduction to regression-testing, enabling repeatable experimentation and fast triage to isolate the root cause.

You should avoid a hypothesis-driven debugging loop for trivial bugs where the root cause is immediately visible, as the structured phases of reproduction, instrumentation, and regression-testing add unnecessary overhead.
