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, Azure status, Azure DevOps status, 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; up to 20 vendors are checked per call, and any past the 20th come back in deferred_vendors to resend. A vendor that cannot be resolved or reached is reported in its own result row, so one bad entry never discards the rest. Every vendor with an active problem gets a pre-filled devops_suggest_action call in nextToolSuggestions.
