Shows how to build a public audit history projection for document approvals that cannot leak private review notes: filter at projection time on both document status and event visibility, store the public read model in a separate table with no private columns, and handle unpublish, rebuilds and counts. Use when exposin…
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 …

Stops an agent loop that keeps rerunning a failed AWS Glue job whose bookmark commit fails, where each rerun reprocesses the same data and piles up duplicates, covering bookmark state, job commit behaviour, and safe rerun design. Use when Glue reruns duplicate output. Not for a Glue job that fails before writing any o…
Covers recovering from an agent rerunning a partial load so already loaded rows are written twice, including finding the duplicate window, deduplicating safely, and making the load idempotent. Use when a retry has duplicated data in the warehouse. Not for duplicates caused by a source that itself sends repeated record…

How to fix a codemod that did not handle CRLF line endings, leaving every file showing as changed: reverting the line-ending churn, normalizing endings in the transform, and re-running cleanly. Use when a codemod diff is all line endings and no substance. Not for real content changes mixed with line-ending noise.
Vectle found the following relevant skills: - agent's patch applier broke with error on windows line endings in the model file - agent edited tests with CRLF line endings: lint failures after healing

How to recover when an agent's regex codemod matched inside string literals and corrupted user-facing copy: reverting, rewriting the transform on an AST, and testing the new version. Use when a regex rewrite damaged text it should not have touched. Not for regex rewrites that were correct but incomplete.
Vectle found the following relevant skills: - agent bumped a dependency inside vendor/ and it drifted from go.mod - the vendored copy no longer matched the module - agent tail filter regex matched nothing: declared deploy healthy

How to fix a migration preview that lied because the dry run used a different postgres search_path than the real migration: aligning the two and making previews trustworthy. Use when the dry-run output does not match what the migration actually does. Not for previews that are wrong for other reasons.
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 mongodb's "cannot convert from BSON type" during a collection migration: finding the documents with unexpected types, cleaning them, and re-running the conversion. Use when a $convert, schema validation, or migration script chokes on a field whose BSON type varies. Not for connection or auth errors.
How to fix pulumi's "resource is pending deletion and cannot be migrated": verifying the real-world resource is gone, removing the stuck state entry, and completing the operation. Use when a resource is wedged in pending-delete after a failed destroy or update. Not for resources that still exist in the cloud.
How to fix typeorm's QueryFailedError "duplicate key value violates unique constraint" during a migration run: finding the conflicting rows, making the data change idempotent, and resuming safely. Use when a migration's INSERT or backfill collides with existing rows. Not for duplicate keys caused by application writes…
How to fix flyway's "Migration checksum mismatch for migration version 12": determining whether the applied migration file was edited after the fact, and choosing between flyway repair and restoring the original file. Use when validate fails on a checksum for an already-applied migration. Not for failed (not yet appli…
