claude-code-debugger

Use when the user asks to "debug this", "fix this bug", "investigate error", "diagnose", "root cause", or reports a crash/exception/failure. Memory-first workflow checks past incidents before investigating.

Use for deep iterative debugging when memory lookup returns LIKELY_MATCH/WEAK_SIGNAL/NO_MATCH, a fix didn't hold, or the user asks for root cause analysis. Not for known fixes or trivial issues.

Use when the user asks to "add logging", "add tracing", "improve observability", "OpenTelemetry", "structured logging", or reports silent failures or no runtime visibility. Generates stack-appropriate logging with optional OTel.
