Diagnose Errors
Use when there are new/rising errors, 5xx spikes, or repeated failure signatures.
Inputs
- Cloudflare Observability MCP (request failures, logs, latency/error trends)
- PostHog MCP (exception signatures, frequency, impacted users)
- Recent git commits/PRs (
git log,gh pr) for regression correlation
Workflow
- Quantify incident window and top error signatures.
- Group related failures into likely root-cause clusters.
- Correlate onset with recent deploys/commits/config changes.
- Propose smallest safe fix and confidence level.
Output
- clustered signatures + impact
- evidence links/ids
- likely owner/code path
- best next action (fix now vs task follow-up)
