Loading the registry…
End-to-end test suite for the anti-hall plugin hooks (zero runtime deps; Node built-in node:test).
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
476 critical findings reported by cisco-skill-scanner, agent-audit-kit, 256 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Claude Skills install to a single target, no runtime picker.
nerlo install -- anti-hall-tests
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- anti-hall-tests ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
5 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 2,192 findings across every scanner that examined this package. 219 of 476 findings rated critical by their scanner were among the dismissals.
Not reviewed is not the same as clean. Those 1 finding stand exactly as their scanners reported them, at full severity, as they would have without this review.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
1,211 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.

26 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

5 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

1 The model gave no reason we were willing to publish, and a verdict without one is not usable evidence.
Rules: YARA_credential_harvesting_generic · Files: /repo/tests/hooks/swarm-guard.test.js · reported by cisco-skill-scanner
Artifact has critical command injection and credential access risks.
The artifact contains numerous instances of command injection via child processes and `eval` in various JavaScript files, enabling shell execution. It also exhibits potential for credential access and path traversal in `plugins/anti-hall/hooks/progress-prune.js`. Additionally, there are many instances of file system access that could lead to data exfiltration.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
