Skill Catalogs
Catalogs are curated collections of certified skills. They provide trust, discoverability, and version management for skills across teams and the community.
Types of Catalogs
Personal Collection
Your private workspace for skills you're developing or have saved. Only you can see these. Not published to any catalog.
Organization Catalog
Skills shared within your organization. Can contain private skills (org members only) or public skills (visible to everyone but managed by the org).
SkillMill Public Catalog
The official public catalog of certified skills. Curated by SkillMill, available to everyone. Skills here have passed safety and quality reviews.
Fork & Version Model
When a skill is published to a catalog, it's forked (copied), not referenced. This ensures:
- 1.Stability
Changes to the source don't break published skills
- 2.Version Control
Each catalog version is a specific snapshot with a version stamp
- 3.Origin Tracking
We track where the skill came from (source repo, commit SHA)
Important: Updates require explicit republication. If you update your source skill, you must submit a new version request.
Publishing Flows
Submit your skill for internal publication. An org admin reviews and approves. Skill is copied to your org's GitHub-backed catalog.
Promote an org-certified skill to the public catalog. SkillMill reviews against public standards. Both catalogs maintain independent versions.
Individual contributors (not in an org) can publish directly to the public catalog. Skills are namespaced under your GitHub username.
"Wild" skills are discovered on GitHub but not yet managed. A verified user can submit them for validation and publish to either catalog.
Namespace & Ownership
All published skills use the format: vendor/skill-name
Use their verified org name (e.g., anthropic/document-skills). Verified via email domain.
Use their GitHub username (e.g., jeffrschneider/pdf-tools). Verified via GitHub OAuth.
GitHub Integration
Catalogs are backed by GitHub repositories for version control, audit trails, and collaboration.

Access & Visibility
Private Skills Stay Private
Private org skills are only accessible to verified members of that organization. There is no cross-org private sharing—if you want another org to use your skill, publish it to the public catalog.
To share across organizations: Promote your private skill to the public catalog. Both organizations can then install it.
