Runs a long swarm of hundreds to thousands of cheap headless coding workers that drive a large failing-test backlog to green. Failures are clustered by signature, each worker fixes one cluster in its own git worktree, a serial no-regression merge gate lands the fixes, the loop resumes across restarts for hours, and it federates across sibling sessions over git branches when one container's CPU is not enough. Use for "fix these thousands of failing tests with a Haiku swarm…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Swarming failing tests A loop that turns a test suite's failures into merged fixes, unattended, for hours: ``` known.json --cluster by signature--> work items --one headless worker each, own worktree--> result JSON --serial gate: apply on main, compat check, run smoke + targets + sample, zero regressions, >=1 target flips--> fast-forward main --> re-check the whole cluster --> repeat ``` Every mechanism in it fixed a failure that cost hours on 2026-10-12, when Haiku 5.5 workers built hcc (a C compiler in Python) against ~42K tests: 1,051 hub workers, 464 merges, $24.88 of worker spend by 18:30Z. The catalogue of those failures, each with its signal and where it is handled, is [references/run-2026-10-12.md](references/run-2026-10-12.md). ```bash SK=/mnt/skills/user/swarming-failing-tests # or <claude-skills clone>/swarming-failing-tests SWARM="python3 $SK/scripts/swarm.py" # every command below; --root defaults to the git toplevel ``` ## When to use it, and when not Use it when **all** hold: a test command can report every test's status as JSON; there are hundreds or more failing tests; a fix can be checked by re-running tests; and …

How to install
mdr add oaustegard/claude-skills/swarming-failing-tests@sha256:ab862c6eda60c693The line at the top of this page pins the label v0.4.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
