Claude Skill

Flagged41composite

Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.

Source:: github.com/benny93/kafui
Provenance:: Found by crawling (provenance, not a security rating)

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.

14 critical findings reported by osv-scanner. The composite score alone does not reflect this — read the per-scanner reports below.

github_release: https://github.com/benny93/kafui, 0 findings

Install

Claude Skills install to a single target, no runtime picker.

nerlo install -- kafui

Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.

cp -r -- kafui ~/.claude/skills/

Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.

10 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.

AI review of these findings

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.

Upheld as real: 477
Dismissed as false positives: 6
Not reviewed: 1

Out of 484 findings across every scanner that examined this package. None of the 14 findings rated critical by their scanner were dismissed.

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.

Why those were dismissed

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.

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

2 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.

In installed code — never dismissed

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.
