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.
