Revised skills only
The public catalog starts at revision 2. Imported source material stays in the revision workspace until a substantive revision passes the publication checks.
Find the right workflow
Search names, descriptions and tags, filter by category, and inspect a skill’s exact instructions before downloading it.
Trace every revision
Each release includes its upstream source, revision summary, change list and evaluation results. New releases retain the recorded revision history.
Portable Markdown
Download the published SKILL.md and review its requirements before adding it to an agent’s supported skills directory. Installation depends on your agent.

Frequently Asked Questions
Does this catalog include unchanged upstream skills?
No. Source imports enter a private revision queue. A skill must have a substantive revision, start at revision 2 or later, and pass the publication checks before appearing in this catalog.
Is this the official skills.sh website?
No. This is an independent Zutilium tool for maintaining and distributing revised skills. Each skill identifies its upstream repository and retains the applicable attribution.
Are evaluation results a guarantee for every AI model?
No. Evaluation results describe the checks recorded for that release. Review the instructions and model context, and test the skill with your own agent and workflow.
How are new revisions published?
Administrators import eligible source material into the workspace, create a revision and run the configured evaluation process. A revision is published automatically only when its required checks pass; unsuccessful attempts stay out of the public catalog.
Does Download SKILL.md install a skill for me?
No. It downloads the published Markdown file. Add it using the installation process supported by your agent and check whether the skill needs additional files or tools.
