Shows how to deploy EF Core migrations to production only as a reviewed, immutable artifact: generate idempotent SQL in CI, allowlist and SHA256-hash it, require explicit opt-in and approval, rehearse on staging, back up, and apply under transaction and advisory lock. Use for gated production EF Core releases. Not for…

Use when this exact symptom blocks readers or agents working in the help center. Not fo…
Fixes check failed with a timeout in the work covered by this query by taking the specific step below first. Use when this exact failure blocks collection, review, or fulfilment. Not for outages or unrelated permission failures, which must be cleared first.

Fixes this failure in the Clay enrichment table - split the table run into chunks, run the timing out step as an async enrichment on a smaller row set, and check whether one provider step is slow for every row or only for rows with a particular input. Prove it on one record, then rerun the full scope and reconcile the…
Fixes a release workflow that fails when the Metabase API times out while the agent tries to pull Metabase query results, by making the workflow poll for completion and resume partial work. Use when the workflow reports a timeout error for a step that may have finished server side. Not for a workflow failing on invali…

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 CI where an unpinned migration CLI version drifted and a minor release changed the generated SQL: pinning the exact version and re-verifying the output. Use when CI generates different SQL than local runs. Not for SQL differences caused by different database versions.
Recovery and prevention after an agent ran prisma migrate dev against a shared staging database and wiped data URIs restoring from backup, and the guardrails that keep migrate dev off shared databases. Use when migrate dev reset a database it should never have touched. Not for migrate deploy issues.

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.
How to fix prisma Error P3015 "Could not find the migration file for a recorded migration": restoring the missing migration folder from version control, or marking the phantom migration rolled back when it never actually applied.

Fixes the Playwright "A test was not run because it exceeded the timeout" sharding failure in CI. It shows how to find the shard and test that overruns, rebalance shards, and mark genuinely slow tests so one long test stops poisoning its whole shard. Use when sharded CI runs report unrun tests with this message while …

Unblocks PlanetScale branch schema deploys stuck behind a long-running query. Use when a deploy sits in blocked or waiting state. Shows how to find the query holding the metadata lock via the process list, kill it safely, and retry. Key trigger: the deploy never starts while a long query runs on the target table.

Fixes agents hanging when wrangler d1 migrations apply stalls on remote after printing 'applying migration'. Use when the migration command hangs indefinitely. Not for migration SQL errors, journal conflicts, or local migration hangs.
Fixes Knex 'Timeout acquiring a connection' during seeds. Use when seed scripts open more concurrent connections than the pool allows or leak them in uncommitted transactions. Key trigger: the timeout appears only under seed load, never under normal queries.
