You say
The production database is unresponsive and I see a spike in 'Lock' wait events. Can you find out what is blocking the queries?
Your agent does
[LOCKCHAIN SENTINEL EVIDENCE REPORT] Root blocking PID: 4022 Blocking SQL: UPDATE orders SET status = 'processing' WHERE id = 882; Blocking transaction age: 4m 12s Blocked session count: 18 Recommended action: Terminate PID 4022. Approval required: YES
About this skill
LockChain Sentinel™ turns complex PostgreSQL lock, deadlock, blocking-chain, and long-running-transaction incidents into a structured, evidence-backed recovery workflow. It helps engineering and SRE teams diagnose the root blocker, map affected sessions, assess risk, and determine the safest remediation path.
Unlike a generic SQL assistant, it follows a disciplined Detect → Diagnose → Evidence Gate → Human Approval → Remediate → Verify → Report process. Diagnostics remain read-only by default, while consequential production actions require explicit human approval.
It is designed for teams that need repeatable incident-response judgment without giving an AI unrestricted authority over production databases.
