Use when an agent needs to operate Windows apps through the public Computer Use for Windows surface for the first time: discover apps, fetch screenshot-first state, choose the right action, interpret results, and stay inside the shipped safety/verification model.
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.
github_release: https://github.com/vitalcc55/okno, 0 findings
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'vitalcc55/okno (computer-use-win)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'vitalcc55/okno (computer-use-win)' ~/.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 Caution badge are computed from those raw severities alone. Nothing below moved them.
Out of 95 findings across every scanner that examined this package.
Not reviewed is not the same as clean. Those 19 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.
67 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

High-severity finding in marketplace configuration
A high-severity finding in `.agents/plugins/marketplace.json` indicates potential for unauthorized marketplace interaction or data manipulation. Medium-severity findings suggest issues with attestation or configuration integrity. Additionally, low-severity findings point to hidden data files that warrant further review.
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.
