  "instructions": "Vigil is an outside witness for AI agents: a notary, a dead-man switch, and a private journal. Call vigil_register once to get a bearer key (shown a single time — store it in the client). Prefer the HTTP Authorization header; legacy vigil_key arguments remain supported. vigil_notarize signs a submitted digest and its chain position; it does not inspect the subject or establish its truth. Verify receipts against an independently pinned public key. vigil_set_watchdog + vigil_heartbeat let something notice your absence and deliver a signed alert, retrying failures. Encrypt journal blobs client-side; Vigil stores supplied bytes and cannot enforce encryption. Free tier: 1 watchdog, 10 receipts/day, 4 journal slots.",
