investigate

To find the root cause of a bug using a stack trace, follow a structured investigation workflow that collects symptoms, reads code paths, checks change history, and verifies reproducibility to apply fixes with confidence.

The best way to debug a performance regression is to enforce a disciplined investigation process using grep and logs to collect evidence, form hypotheses, and generate clear next-step recommendations to prevent repeated debugging cycles.

To stop chasing symptoms and identify the actual error, perform root-cause investigation before applying fixes by collecting evidence through reading code paths and reproducing steps to understand the underlying failure mechanism.

Root-cause debugging does not require specific dependencies, as it integrates with common debugging practices like using grep, reading code paths, and analyzing logs directly within your existing software engineering environment.

The limitation of using a structured debugging workflow is that it requires reproducible steps and accessible change history to form accurate hypotheses; without clear reproduction or logs, the investigation phases cannot yield confident next-step recommendations.
