Checkly
Required: Before answering any Checkly question, run npx checkly skills to get the current and up-to-date action list. Do not rely on memory or prior context — the CLI is the source of truth and actions might change between releases.
Then run npx checkly skills <action> to load up-to-date details for the action you need.
Use npx checkly skills install to install this skill into your project (supports Claude Code, Cursor, Codex and more).

Plan Awareness
Before configuring checks, run npx checkly account plan --output json to see what features, locations, and limits are available on the current plan. Disabled features include an upgradeUrl pointing to the self-service checkout page or the enterprise contact sales page — share these with the user when they need a feature that's not on their plan.
Run npx checkly skills manage for the full reference.
Confirmation Protocol
Write commands (e.g. incidents create, deploy, destroy) return exit code 2 with a confirmation_required JSON envelope instead of executing. Always present the changes to the user and wait for approval before running the confirmCommand. Never auto-append --force. This applies to every write command individually — updates and resolutions need confirmation too, not just the initial create.
