Diagnoses dbt test flakiness where the same test passes on rerun with zero code or data changes. Use when a test flips between pass and fail across identical runs. Not for tests that fail consistently on real bad data.
Vectle found the following relevant skills: - agent loop detected: re-running failed dbt tests with no changes - dbt singular test passes locally but fails in dbt cloud - …

How to fix a migration that passed locally on sqlite but failed in production on postgres: reproducing on real postgres, fixing the dialect differences, and making CI test against postgres. Use when the local/prod database mismatch hides failures. Not for failures that reproduce on postgres locally.
Finds the polluting test behind order-dependent failures that only appear in the full pytest suite. Use when a test passes alone but fails in the full run. Covers confirming isolation, bisecting the suite, using random-order seeds, and fixing the polluter's cleanup. Not for failures that reproduce alone.
Finds the shared file handle behind the I/O operation on closed file flake in parallel pytest runs. Use when the error appears intermittently with xdist. Covers finding module-level or module-scoped file handles, giving each test its own file via tmp_path, and rerunning in parallel. Not for single-process occurrences.
Fixes retry band-aids that double suite time instead of fixing the flaky fixture. Use when test-level retries were added over an unstable test database. Covers finding the DB flake, fixing setup/teardown, and removing the retries. Not for retries around genuinely external services.
Replaces an agent's habit of skipping flaky test files with a real quarantine policy: labeled, owned, time-boxed, and still running in a separate lane. Use when flaky tests get skipped into invisibility instead of quarantined. Not for permanently obsolete tests, which should be deleted, not quarantined.
Catches order-dependent healed tests by running each healed test alone, in random order, and with its neighbors. Use when a healed test passes in the suite but fails standalone, or vice versa. Not for tests that are intentionally ordered, which should be explicitly marked and isolated, not silently dependent.
Fixes shard-unsafe tests that fail only under CI sharding. Use when a test passes locally and in unsharded CI but fails on sharded runs. Covers finding the shared global state, making it unique per test, and verifying under sharding. Not for failures that happen unsharded.
Fixes retry band-aids that double suite time instead of fixing the flaky fixture. Use when test-level retries were added over an unstable test database. Covers finding the DB flake, fixing setup/teardown, and removing the retries. Not for retries around genuinely external services.
Isolates Mocha --parallel test files that leak state into each other. Use when files pass alone but fail together under --parallel. Not for order dependence inside one file.
Isolates databases for parallel Cucumber scenarios so concurrent runs stop colliding. Use when scenarios pass serially but fail in parallel with unique-constraint violations or dirty reads. Not for parallel slowness or for collisions inside a single scenario.

Fixes test failures caused by the app behaving differently when CI=true is set. Use when a test passes locally but fails on CI and the app changes behavior under CI. Covers auditing CI-env-dependent code paths, making tests env-aware, and documenting the CI=true contract. Not for genuine timing flakes.
Fixes healing patches that pass solo but fail in the full suite due to module-level caches leaking state between tests. Use when the healed test passes alone and fails in suite. Covers finding the leaked cache, clearing it in setup/teardown, and requiring a suite-subset run before accepting any heal. Not for genuinely…
Fixes test-healing agents quarantining tests that failed due to database pollution from the agent's own earlier runs. Use when quarantined tests pass on a clean database. Covers resetting DB state between healing runs, making setup/teardown hermetic, and re-verifying quarantines on a clean slate. Not for genuinely ord…
Fixes test-healing agents breaking unrelated tests by editing shared mocks or fixtures. Use when a healer's fix to one test breaks many others. Covers scoping fixes to the failing test, cloning shared fixtures before editing, and running the affected test subset before committing a heal. Not for genuinely coupled test…
Unblocks agent-driven dbt runs when one unrelated failure blocks the whole test suite. Covers scoping runs with dbt selectors, testing models in dependency order, and isolating failures without skipping real breakage. Use when dbt test or build fails on a model the agent did not touch.
