Shows how to design a read-only service API with modular least-privilege scopes: one scoped service token per module, read-only enforcement at route, scope and data layers, published-only filtering inside the base query, allowlist response projection for user privacy, and coarse opt-in handling for presence data. Use …
Shows how to build an approval workflow in ASP.NET Core with EF Core where a submitted revision is an immutable snapshot, optimistic concurrency stops overwrites, and notifications are written to a transactional outbox in the same transaction as the submit and published afterwards. Use when approvers must approve exac…

Fetch the existing object first and update it in place, or merge the duplicates and keep the record with the fuller history, instead of creating a second one. Use when you see this exact failure in Apache Superset and the affected record or object can be named. Not for a different Apache Superset error with another me…
Fetch the existing object first and update it in place, or merge the duplicates and keep the record with the fuller history, instead of creating a second one. Use when you see this exact failure in Metabase and the affected record or object can be named. Not for a different Metabase error with another message, or for …
Diff the definition against the live source schema, fix the named field type or reference at its definition rather than at each consumer, and rebuild or revalidate in dependency order. Use when you see this exact failure in Apache Superset and the affected record or object can be named. Not for a different Apache Supe…
Fixes a Metabase native question whose parameter fails with a variable not found error by matching the variable name and type between the query and the dashboard. Use when a native SQL card breaks on its parameter while the raw query runs. Not for a GUI question filter problem, which uses field mapping instead.
Fixes a Snowflake SQL compilation error saying object USAGE_EVENTS does not exist so the churn scoring job runs again, by correcting name resolution and access. Use when the job fails at compile time. Not for a query that runs but returns wrong numbers.
Fixes a Looker dashboard that fails with a query execution timeout by trimming the explore, adding filters and checking the warehouse. Use when tiles spin and then time out on load. Not for a Looker login or permission failure with no timeout.
Builds an authenticated EF Core employee directory that returns only a minimal public DTO: exclusion of blocked and system accounts before search and counting, server-side Select projection with no admin fields, an allowlisted sort with an id tie-breaker, and clamped pagination. Use when a directory endpoint returns u…
Fixes the NoneType has no attribute execute crash during dbt run, where code expected a connection or cursor that was never opened. Use when a macro, hook, or adapter call fails with this exact attribute error. Not for ordinary warehouse SQL errors returned by the database.
Vectle found the following relevant skills: - dbt incremental model full refresh failed: unique key collision - dbt incremental merge failed: cannot merge on column of type variant
Problem outcome: unknown
Public search query: dbt incremental model merge not deduplicating: duplicate rows keep growing
Problem outcome: unknown
Fixes the silent empty table outcome where dbt run succeeds but the Snowflake table has no rows. Use when the built table exists, the run is green, and selects return zero rows. Not for failed runs or missing tables.

Fixes kernel OOM when a notebook query returns millions of rows by pushing aggregation to the database, reading in chunks, or sampling. Keeps large results out of kernel memory. Not for OOM caused by model training or large in-memory joins, and not for slow queries that return small results.
