diagnose-error

What problem does it solve?

Diagnose an incident by turning limited production evidence (logs, traces, metrics, and user reports) into a confirmed root cause and actionable next steps.

Core Features & Use Cases

• Capture the symptom precisely: Preserve the exact error message, reproduction details, timing, frequency, and blast radius to prevent losing the thread.
• Locate and connect evidence end-to-end: Find the originating log line, reconstruct the request trace, and identify the failing code path and violated invariant.
• Hypothesize, test, and document: Correlate with recent changes, reproduce or validate the suspected mechanism, and produce a clear root-cause writeup with reproduction steps and recommendations.

Quick Start

Use diagnose-error when an on-call alert reports a production error and you need to work from the first log occurrence to the exact failing code location and a confirmed root cause.
