Error Diagnosis & Triage

Investigate product errors by triaging across three auto-captured event types — [Amplitude] Network Request, [Amplitude] Error Logged, and [Amplitude] Error Click — to identify what's broken, which users are affected, and what's causing it. This skill cross-references all three signals to surface causal chains (failed request → JS error → user frustration) rather than treating each in isolation.

This is a reactive investigation skill — the user has a signal (spike, complaint, experiment regression, gut feeling) and wants to understand what's happening. For proactive monitoring, use the monitor-reliability skill instead.

CRITICAL: Event Reference

These are the three auto-captured events this skill operates on. Never guess property names — use exactly these.

[Amplitude] Network Request — Browser network requests. Key properties: [Amplitude] URL, [Amplitude] Status Code, [Amplitude] Duration, [Amplitude] Request Method, [Amplitude] Request Type, [Amplitude] Request Body Size, [Amplitude] Response Body Size, [Amplitude] Start Time, [Amplitude] Completion Time, [Amplitude] Page Path.

[Amplitude] Error Logged — JavaScript errors. Key properties: Error Message, Error Type, Error URL, File Name, Error Lineno, Error Colno, Error Stack Trace, [Amplitude] Error Detection Source.
