Inspect SSL/TLS certificate health for one or more domains by performing a real TLS handshake. Works for any internet-accessible domain — no vendor registry required. Reports days to expiry (flagged at < 30 days warning and < 7 days critical), certificate subject and SANs, issuer, hostname coverage, chain-trust verification, TLS protocol version negotiated (flags TLS 1.0/1.1 as insecure), cipher suite, and HSTS presence. The handshake completes even for a certificate clients would reject, so a broken certificate is reported rather than hidden behind a connection error: a hostname mismatch surfaces in cert.hostname_verification_error and a chain-trust failure (self-signed, untrusted root) in cert.authorization_error, both status "critical". If a domain fails to connect at all, check devops_check_dns first — the name may not resolve.

Resolve DNS records for one or more domains across multiple public resolvers and compare what each resolver returned. Works for any domain — no vendor registry required. Reports records found (A/AAAA/CNAME/MX/TXT/NS), resolution latency per resolver, and a typed outcome per resolver and record type so "the domain does not exist" (nxdomain), "the resolver could not answer" (servfail), and "no record of this type" (nodata) stay distinguishable. Resolver disagreements are reported without asserting a cause: partial_resolution (some resolvers answered, others returned nothing) points at a real propagation or resolver problem, while value_variation (every resolver answered with different values) is the normal steady state for anycast and geo-steered domains. Pair with devops_check_certs when a domain resolves but TLS to it is failing.

Fetch incident history and scheduled maintenance windows for a vendor. Returns full incident timeline — each investigator update, affected components, and resolution. Filter by status to focus on active incidents (use before deploy), resolved history (for postmortem), or upcoming maintenance windows. Page through long histories with limit + offset — a truncated result discloses the total and returns the value to page with in nextOffset. Some vendor feeds cap their own history: when upstreamCeiling is present the vendor API returned everything it will serve, and older incidents are reachable only on the vendor status page, not at a higher offset. An empty result explains itself in notice.

List vendors in the built-in registry, optionally filtered by category or name search. Returns slug, display name, category, and status page URL for each entry. Use to discover the correct slug to pass to other tools, or to see which vendors are available before configuring a stack.

Check the current health status for one or more vendors. Accepts registered vendor slugs (e.g., "github", "aws", "gcp", "gitlab") or raw Atlassian Statuspage base URLs. Registry entries are served by each vendor's native status API (Statuspage, Status.io, Slack, AWS Health, Google Cloud Service Health, Firehydrant) and normalized to one shape. Returns per-vendor operational indicator (none = all clear, minor, major, critical, maintenance = scheduled window), degraded components, and active incidents. Use mode: "detailed" for component lists and maintenance windows, narrowed with component_filter and bounded by component_limit. Batch-friendly — pass a list to check your full stack in one call; a vendor that cannot be resolved or reached is reported in its own result row, so one bad entry never discards the rest.

Return an incident-response playbook tailored to a vendor degradation, with pre-filled follow-up tool calls. Synthesizes category-specific guidance (cloud, CDN, dev-platform, auth, etc.) from built-in incident knowledge and the provided context. Use after devops_status_check or devops_get_incidents surfaces a problem to determine what to investigate next.

Check the health of a named vendor stack — a saved list of vendors representing your infrastructure dependencies. On the first call, provide vendors to define the stack; subsequent calls can omit vendors to reuse the persisted list. Returns a unified health snapshot with an aggregate rollup plus per-vendor detail. A vendor that cannot be resolved or reached is reported in its own row and left out of the saved stack, so one bad entry never discards the sweep. Ideal for morning status checks or pre-deploy sweeps. Multiple stacks can coexist (e.g., "production", "staging").
