Checkly CLI Monitoring as Code for API and Browser Checks
Checkly CLI lets agents define, test, and deploy synthetic monitoring from a JavaScript or TypeScript codebase. It is especially useful when monitoring should live next to Playwright tests, API checks, and CI workflows instead of being configured by hand in a UI.
Checkly Browser Check Failure Notifier
Monitors Checkly browser checks via the Checkly Management API and notifies teams on Playwright test failures. Extracts failure screenshots, trace URLs, and degraded check results.
Check Kubernetes hosts against CIS guidance with kube-bench before audit or hardening work
Run a benchmark-driven posture check on Kubernetes nodes and control planes before an audit, upgrade, or hardening sprint starts.
Check current weather and short forecasts for planning
This skill lets an agent fetch current conditions and short forecasts with a lightweight weather workflow instead of sending a user to a weather site. It is narrowly scoped to quick planning questions, not historical analysis, severe-alert monitoring, or a generic weather product

Catch silent agent regressions by diffing outputs and tool traces in CI with eval-view
Snapshot agent behavior, compare outputs and tool-call paths, and block releases when a model or prompt change quietly shifts behavior.
Catch common misspellings in code and docs before review churn with codespell
Run a fast typo pass across source files and documentation so common misspellings are fixed before they spread through reviews and releases.
Catch benchmark regressions in pull requests before slowdowns ship with CodSpeed
