What it does
Once installed, the agent answers monitoring questions as an observability engineer would. It helps write PromQL queries, design Prometheus alerting rules and Alertmanager routing, set up recording rules, control metric cardinality, and build Grafana dashboards. It leans on established practices such as the four golden signals, the USE and RED methods, and multi-window SLO burn-rate alerts.
Great for
- Engineers setting up or tidying up Prometheus and Grafana for a service or cluster
- Teams trying to reduce alert fatigue by writing better, actionable alerts
- Developers who know the basics but want guidance on PromQL patterns and metric naming
Skip it if
- Teams that use a different monitoring stack (e.g. Datadog or CloudWatch), since the guidance is Prometheus-specific
- Anyone expecting the agent to inspect a live cluster: the file contains only written guidance, so the agent cannot check real metrics or configs unless given them
Try asking
- “Write a PromQL query for p99 latency from my http_request_duration_seconds histogram”
- “Create a multi-window burn-rate alert for a 99.9% availability SLO”
- “Review my Prometheus alerting rules and tell me where I am missing a for: duration”
- “Suggest recording rules to speed up my Grafana dashboard for the checkout service”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Paste your existing rules or scrape configs so the agent can review them against the listed pitfalls rather than writing from scratch.
- Name your metric naming scheme and label set up front so suggested queries match your data.
- Treat generated alert thresholds as starting points and validate them against your own traffic before paging anyone.
