Synthetic Check Investigator

Investigate Synthetic Monitoring check failures by triaging probe data, classifying failure scope, and identifying root cause. Experienced operators need actionable diagnosis, not hand-holding.

Core Principles

1. Use gcx commands — do not call Grafana APIs directly
2. Trust the user's expertise — skip background explanations
3. Use -o json for agent processing, default format for user display
4. Show timeline graphs for time-series data — they communicate trends faster than text
5. Collect errors; report them at the end, not interleaved in workflow steps

Prerequisites

gcx configured with an active context and appropriate permissions.
