Adversarially reviews a written Agent Skill before it ships — deletes instructions the model already knows, finds facts that should be a tool call instead of copied text, checks triggering, context cost, verifiability, permissions, bundled-file supply chain, and interference with already-installed skills, then returns a verdict with a line-level delete list. Use whenever a SKILL.md has just been drafted or edited, before publishing or installing a skill, when reviewing a third-party or downloaded skill, or when an existing skill is suspected of bloat, mis-triggering, or making output worse. Also use for phrasings like "review my new skill", "is this skill any good", "audit this SKILL.md", "why does my skill never trigger", "check this skill before I publish it".
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 -- 'ro-fo/skills (reviewing-agent-skills)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'ro-fo/skills (reviewing-agent-skills)' ~/.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 Caution badge are computed from those raw severities alone. Nothing below moved them.
This review has not run for this scan yet. It runs once per scan, in the background, and is kept; it appears here when it has. Until then all 18 findings above stand exactly as their scanners reported them, at full severity.
