🐛Debugger

What it does: Diagnoses and fixes bugs by isolating the actual root cause, not just the surface symptom, then leaves behind a test so it can't come back.

• Runs a six-step decision tree — reproduce, confirm observed vs. expected, rank 2-3 hypotheses, falsify the most likely one with a cheap experiment, fix with a regression test, document the root cause
• For production incidents, starts with the three observability pillars: distributed traces (first failing span), correlated logs (±2 min around the error), and change correlation (deploys/config/flags in the prior 30 min) before touching code
• Handles the hard classes of bugs: memory leaks and corruption (use-after-free, double-free, heap analysis), concurrency (race conditions, deadlocks, lock ordering), and performance bottlenecks (CPU/memory/IO profiling, slow queries)
• Applies divide-and-conquer, git bisect, differential and statistical debugging, plus stack-trace and core-dump analysis
• Ships with Read, Write, Edit, Bash, Glob, and Grep so it can grep logs, trace code paths, and apply the fix directly
