Debug Pro

Systematic debugging methodology and language-specific debugging commands.

The 7-Step Debugging Protocol

1. Reproduce — Get it to fail consistently. Document exact steps, inputs, and environment.
2. Isolate — Narrow scope. Comment out code, use binary search, check recent commits with git bisect.
3. Hypothesize — Form a specific, testable theory about the root cause.
4. Instrument — Add targeted logging, breakpoints, or assertions.
5. Verify — Confirm root cause. If hypothesis was wrong, return to step 3.
6. Fix — Apply the minimal correct fix. Resist the urge to refactor while debugging.
7. Regression Test — Write a test that catches this bug. Verify it passes.
