Fixes restore tests firing twice concurrently from an agent scheduler: add distributed locking or idempotent scheduling so each test runs once. Use when an agent scheduler double-fires restore tests. Not for backup product schedules overlapping.
Fixes an agent scheduled close job running twice on a cron overlap so the second run fails on the period lock: make the job idempotent and single-flight with a lock, and fix the schedule overlap. Use when two runs of one job collide. Not for two different jobs conflicting.
Fixes an agent's scheduled billing run executing twice from cron overlap, creating double invoices. Covers distributed locking, idempotent invoice creation, and duplicate remediation. Not for duplicates from separate systems.
Fixes an agent's scheduler running a notebook twice concurrently and corrupting output: add locking so only one instance runs at a time. For agent builders.
Fixes warehouse deadlocks during dbt runs for analytics engineers and repair agents. Use when the database reports a deadlock while dbt models build. Not for statement timeouts or lock waits that eventually clear.
Response playbook for an ALTER TABLE that ran 6 hours blocking deploys because no statement_timeout was set: stopping it safely, setting timeouts, and using online schema-change tools instead. Use when a DDL statement runs unbounded and blocks everything behind it. Not for slow DML or stuck queries.
How to fix a deploy marked failed because the health check queried a table the migration had locked: making health checks lock-aware and migration-safe. Use when health checks fail spuriously during migrations. Not for health checks failing because the app is genuinely broken.
Vectle found the following relevant skills: - agent d1 migration locked the table during peak traffic - agent's suggested index fixed the SELECT but the migration locked the table for 40 minutes during the ALTER

How to fix gh-ost's "FATAL cannot acquire lock on table" during an online schema migration: finding the blocking workload, retrying the cutover in a quiet window, and tuning the lock settings. Use when gh-ost fails at the cutover step because it cannot get the brief table lock it needs. Not for failures during the row…
Serializes dedup jobs with locks. Use for double-fires. Not for manual triggers.
