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

Gives agents a playbook for Redshift VACUUM operations that never finish: lock contention, sizing, and bounded waits. Use when an agent waits on VACUUM past its timeout. Not for VACUUM that fails fast.
Gives agents a playbook for Snowflake validation queries that hang: warehouse state, query queues, and lightweight checks. Use when a row count or similar check never returns. Not for checks that return wrong numbers.
Gives agents a playbook for Athena queries that never return: query states, cancellation, and rewriting. Use when an agent waits on an Athena query stuck in a non-terminal state. Not for queries that fail fast.
Gives agents a playbook for dbt Cloud jobs stuck in queued: run slots, account limits, and when to stop waiting. Use when an agent waits on a dbt Cloud job that never leaves queued. Not for jobs that run and fail.
