Systematic troubleshooting using the Scientific Method. Use when debugging crashes, tracing errors, diagnosing unexpected behavior, or investigating exceptions. (triggers: debug, fix bug, crash, error, exception, troubleshooting)

Priority: P1 (OPERATIONAL)
Systematic, evidence-based troubleshooting. Do not guess; prove.
🔬 The Scientific Method
- OBSERVE: Gather data. What exactly is happening?
- Logs, Stack Traces, Screenshots, Steps to Reproduce.
- HYPOTHESIZE: Formulate a theory. "I think X is causing Y because Z."
- EXPERIMENT: Test the theory.
- Create a reproduction case.
- Change one variable at a time to validate the hypothesis.
- FIX: Implement the solution once the root cause is proven.
- VERIFY: Ensure the fix works and doesn't introduce regressions.
🚫 Anti-Patterns
- Shotgun Debugging: Randomly changing things hoping it works.
- Console Log Spam: Leaving
print/console.login production code. - Fixing Symptoms: masking the error (e.g.,
try-catchwithout handling) instead of fixing the root cause.
🛠 Best Practices
- Diff Diagnosis: What changed since it last worked?
- Minimal Repro: Create the smallest possible code snippet that reproduces the issue.
- Rubber Ducking: Explain the code line-by-line to an inanimate object (or the agent).
- Binary Search: Comment out half the code to isolate the failing section.
