Observability health check

Read references/mcp.md first for the tool contract, the key scopes, and the 72h window. This skill is read-only and uses metadata tools only — no trace content, so no injection surface. If that file isn't present (this skill was lifted out on its own), ask the user for the plugin's references/mcp.md, or fall back to the hard rules: every tool is read-only, observation queries cap at a 72-hour window, and a Metadata-only key exposes 7 tools while a With-content key exposes all 9.

Run a fixed diagnostic sequence that turns "it's not working" into a specific cause, then report a short status checklist with the exact fix for anything red. Most signals are ambiguous alone — an empty trace list has several possible causes — so run the steps in order and interpret them together, each one narrowing the fault.
