Fixes agent test matrices hanging after queueing hundreds of restore combos: prune the matrix by risk, stream execution with progress, and time-box the whole run. Use when a restore test matrix of hundreds of combinations hangs. Not for sandbox crashes from parallelism alone.
Fixes parallel restore tests crashing the sandbox: cap concurrency from measured sandbox capacity, isolate tests per environment, and queue excess work. Use when parallel agent restore tests overload their sandbox. Not for a single test crashing a VM from inside.
Retries intermittent pytest failures with the pytest-rerunfailures plugin. Use when a test fails randomly and passes on retry, via the flaky marker or the --reruns flag. Not for consistently failing tests.
Fixes nuclei running out of file descriptors during a large authorized scan by raising the shell limit and cutting nuclei concurrency to match. Use when nuclei dies with too many open files partway through a big in-scope target list. Not for target-side connection refusals, which are a different failure.

Fixes trufflehog 'too many open files' failures by raising the file-descriptor limit and narrowing the scan. It distinguishes fd exhaustion from memory issues and gives systemd, Docker, and CI variants. Not for OOM kills or scan-result tuning.

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.
Vectle found the following relevant skills: - pytest "DID NOT RAISE" flaky: expected exception raised only sometimes under parallel xdist - pytest "sqlalchemy.exc.OperationalError: database is locked" in parallel CI runs: how to fix

Raises the file-descriptor limit for pytest-xdist workers in CI. Use when parallel runs fail with OSError: [Errno 24] Too many open files. Covers confirming the limit, raising it with ulimit in the CI step, reducing worker count, and checking for leaked handles. Not for the same error without xdist.
