Loading the registry…
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.
86 critical findings reported by cisco-skill-scanner, agent-audit-kit, 70 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 -- helpers
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- helpers ~/.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 1,595 findings across every scanner that examined this package. 16 of 86 findings rated critical by their scanner were among the dismissals.
Not reviewed is not the same as clean. Those 10 findings 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.
501 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.
Rules: COMMAND_INJECTION_EVAL, FILE_MAGIC_MISMATCH, AAK-TASKS-003 and 4 more · Files: /repo/config_root/config/test/test_config.py, /repo/helpers/lib_tasks/test/test_lib_tasks.py, /repo/helpers/test/test_hintrospection.py and 214 more · reported by cisco-skill-scanner, agent-audit-kit
141 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

2 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.

Critical command injection and system modification risks identified.
The artifact contains critical command injection vulnerabilities in configuration files and video generation scripts, allowing for arbitrary shell execution. It also exhibits critical system modification capabilities in cleanup scripts and path traversal risks in video processing. Additionally, there are high severity findings for dynamic code execution, potential secret exfiltration over the network, and various other command injection points.
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.
