Health Summary Tool

The summarise_sandbox_health tool returns a compact diagnostic snapshot for a sandbox in a single call.

Context Reduction

Without this tool, diagnosing “why is X down?” requires 3+ MCP calls:

1. inspect_sandbox — ~2 KB response
2. get_sandbox_logs — up to 50 KB of stderr
3. exec_in_sandbox "psql -c SELECT 1" — ~1 KB response

This tool replaces all three with a single call that returns ~500 bytes of structured diagnostic data.
