What it does

When installed, the agent gets a reference guide for setting up production monitoring alerts and on-call rotations. It knows how to rank alert severity, write alert rules in Prometheus, route notifications to Slack or PagerDuty through Alertmanager, and define PagerDuty services, escalation policies and weekly on-call schedules using Terraform examples. It explains good alert design, such as making alerts actionable with runbook links and alerting on user-facing symptoms rather than causes.

Great for

  • Engineers or SREs setting up monitoring and paging for a production service
  • Teams moving from noisy alerts to a clearer severity and escalation structure
  • Someone who needs example Prometheus, Alertmanager or PagerDuty configuration to adapt

Skip it if

  • People without access to the monitoring and paging systems, since the skill only produces configuration text and cannot run it for them
  • Anyone who would apply the example configs unchanged: they contain placeholder keys and URLs (such as a Slack webhook marked xxx and example.com runbooks) that must be replaced, and wrong routing can silence or misdirect real pages
  • Non-technical users, because the content assumes familiarity with Prometheus, Terraform and on-call tooling

Try asking

  • “Write a Prometheus alert rule that fires when my API's 5xx error rate exceeds 5% for five minutes”
  • “Draft an Alertmanager config that sends critical alerts to PagerDuty and high alerts to a business-hours Slack channel”
  • “Create a Terraform PagerDuty service and a weekly primary on-call schedule with an escalation policy”

    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

  • Review every generated config before applying it, especially routing and escalation rules, because mistakes can silence critical pages.
  • Replace all placeholder values (service keys, webhook URLs, runbook links) with your real ones and keep secrets out of files committed to git.
  • Ask the agent to tailor severity levels and thresholds to your own SLOs and traffic patterns rather than using the example numbers as-is.
