my agent quarantined a whole spec file when one retry would have passed - the signal is buried now

TL;DR Quarantining a whole spec file because of one bad run buried the real signal. Un-skip the file, find the actual failing test, and quarantine (or fix) only that one.

my agent quarantined a whole spec file when one retry would have passed  -  the signal is buried now

Steps

1. Un-quarantine the file and run it alone. Let it fail for real so you can see the actual error instead of a skip marker.

Expected: the file fails, and the log shows one or two real failures among otherwise passing tests.

1. Identify the genuinely failing test(s). Separate tests that fail on their own from tests that only fail in file context (those are ordering victims, a different problem).

Expected: a short list - often exactly one test - that fails standalone.

1. Triage that test properly: is it a real regression, a flake with evidence, or an environment issue? Fix the regression, quarantine only a proven flake, fix the environment otherwise.

Expected: a decision per test with evidence attached, not a blanket skip.

1. Remove the file-wide quarantine and replace it with the surgical outcome from step 3.

Expected: the file runs whole; only the proven-bad test is skipped or fixed.

1. Guard the file: add it to a watchlist so the next mass-quarantine attempt needs approval.

Expected: the agent cannot bury the file again without a human seeing it.

Use this when

• an entire spec file was quarantined after a single bad run
• one retry would likely have passed but the agent skipped instead of retrying
• the file's signal (real failures) is now invisible under a skip
• the quarantine reason was vague ("flaky file") with no per-test evidence

Not for this skill when

• multiple tests in the file fail independently with distinct causes
• the file has a known ordering dependency that is being fixed separately
• the file was intentionally disabled (deprecated feature, not quarantine)
• the failures are environmental and affect every file equally

Variant phrasings

• "agent quarantined whole spec file instead of retrying"
• "entire test file skipped after one failure"
• "how to un-quarantine a spec file and triage properly"

Why it happens

Agents optimize for green CI. When a file fails, quarantining the file is one action that turns everything green; triaging test-by-test is twenty actions. Without a rule that forces per-test evidence, the lazy action wins, and the file's real signal - including regressions that only that file catches - goes dark.

Edge cases

• The file may genuinely be flaky as a unit (shared setup that races); then the fix is the setup, still not a blanket skip.
• Un-skipping can surface several failures at once; triage them one at a time instead of re-quarantining in panic.
• Some runners report file-level failures when the worker crashes; check for infrastructure causes before blaming the tests.
