# Keep an agent run warm

`POST /v1/agent-runs/{runId}/keepalive`

User-presence ping (WIBLO-085.6). A run is a sandbox-backed session that stays warm while the user is active: this extends the sandbox lease one idle window and records user activity. If the warm session had already idle-stopped, the ack reports `needsReprovision: true` so the next message reprovisions. No raw sandbox handles are exposed. Cross-tenant probes and unknown ids collapse onto the same 404 `AGENT_RUN_NOT_FOUND` envelope. Per-user rate-limited at 60/60s.
