Analyze SQL Server lock blocking from sys.dm_exec_requests, sys.dm_exec_sessions, sys.dm_os_waiting_tasks, sys.dm_tran_locks, open-transaction DMVs, blocked process reports, index operational stats, Query Store lock waits, and community tool output such as sp_WhoIsActive, sp_BlitzWho and sp_HumanEvents. Applies 55 checks (BL1–BL55) covering blocking chain topology and head-blocker identification, head-blocker state classification against the six documented blocking scenarios, lock-level…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SQL Server Blocking Review Skill ## Purpose Identify the head of a blocking chain, explain why it holds its locks, and give a ranked remediation path. Applies 55 checks (BL1–BL55) across nine categories: - **BL1–BL7** — Blocking chain topology: head blocker identification, block duration, chain depth, fan-out, cross-database chains, concurrency exhaustion, and chronic recurrence across captures - **BL8–BL15** — Head-blocker state classification: maps the head blocker to the documented blocking scenarios (long-running query, sleeping session with an open transaction, orphaned transaction, rollback, client not fetching results, client/server distributed deadlock), plus non-lock waits and maintenance work at the head - **BL16–BL23** — Lock-level evidence: lock escalation to table locks, schema modification locks, hot resource contention, key-range locks, lock conversion waits, application locks, and lock footprint size …

How to install
mdr add vanterx/mssql-performance-skills/sqlblocking-review@sha256:65314c239221148dThe line at the top of this page pins the label git:20261006.2c73ad2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
