# crucible-agent-maintain-only-latest > Maintain only the latest check result for each monitored target in concurrency-safe memory and expose it through the specified FastAPI current-status endpoint. A tool, not a standing agent service — see `input.schema.json`/`output.schema.json` for its contract. Generated by crucible-agent-decomposer for a plan gap step; language and structure are whatever the capability actually needs, not a fixed layout.
