Fact-checks factual claims against live web sources and against the local codebase, reporting each one with a verdict, a correction and a citation. Use when the user asks to fact-check or verify a document, article, draft, README or design doc, to check whether a claim is true, to confirm that what the docs say about the code is still what the code does, to trace whether a stated behaviour holds by following the call paths, to source or back up statements, or to audit the accuracy of what Claude itself said earlier in the conversation. Not a code review: it checks claims made about the code, not the quality of the code.
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.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'adampie/skills (fact-check)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'adampie/skills (fact-check)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 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 13 findings across every scanner that examined this package.
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.

Plugin configuration has high-severity findings.
The artifact contains a plugin configuration file, `.claude-plugin/marketplace.json`, which exhibits multiple high-severity findings. These findings indicate potential issues with how the plugin is configured for marketplace interaction. Additionally, there are low-severity findings related to a vague description and informational findings regarding a missing license in the manifest.
Concern level assessed by the review: High. 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.
