Inspect SSL/TLS certificate health for one or more domains via a real TLS handshake. Reports expiry, chain depth, protocol version, cipher suite, and HSTS presence. Pure TypeScript — no external API.

Resolve DNS records and verify propagation for one or more domains across Google (8.8.8.8), Cloudflare (1.1.1.1), and Quad9 (9.9.9.9). Reports per-resolver latency and resolver discrepancies. Pure TypeScript — no external API.

Fetch incident history for a vendor — active, resolved, or scheduled maintenance. Returns the full incident timeline with per-update bodies and affected components.

List vendors in the built-in registry, optionally filtered by name or category. Returns slug, display name, category, and status page URL.

Check the current health status for one or more vendors. Returns per-vendor indicator (none / minor / major / critical / maintenance), degraded components, and active incident summaries.

Instruction tool — returns a tailored incident-response playbook and pre-filled follow-up tool calls given a vendor name and optional incident context. No external calls; fully deterministic.

Check the health of a named vendor stack persisted in session state. Pass vendors once to save the list; subsequent calls reuse it. Returns an aggregate health rollup plus per-vendor detail.
