A public registry that collects the “skills” and “plugins” that give AI agents new capabilities. Built by OpenClaw and launched in March 2026. A skill is treated as a bundle of a SKILL.md file plus supporting files, versioned with a changelog much like an npm package. Search is not limited to keyword matching — vector search finds skills by meaning — and anything you find can be pulled into your workspace with a single command. ClawHub itself is open source under the MIT license and free to use. The catalog includes skills for the tools people already use, such as GitHub, Slack, Notion, and Google Drive.
Key Features
- Publish skills with version control: Publish a folder containing
SKILL.mdas-is, and ship updates with version numbers and changelogs. Past versions remain in the history, so it is always clear which release you are running - Vector search to find skills by intent: Search uses embedding-based semantic matching (OpenAI’s
text-embedding-3-smallwith a Convex vector index). Describing a goal such as “review pull requests” surfaces the relevant skills - Install straight from the CLI: After
npm i -g clawhub, work throughclawhub search(find),clawhub install(add), andclawhub update --all(update everything). Installed skills land in askillsdirectory under your working folder and are recorded in.clawhub/lock.json - Pin to freeze your local copy: Versions can be pinned so that updates do not silently overwrite a local skill. Useful when you want to stay on a release you have already verified
- Plugin publishing and GitHub imports: Beyond text-based skills, ClawHub supports publishing code plugins (their manifests must declare the OpenClaw versions they are compatible with). Importing from an existing GitHub repository is also supported
- Registry management and trust features: Signed manifests, moderated releases, merging duplicate entries, ownership renames that do not break existing links, and soft delete with restore

ClawHub is offered as a free service, and the software itself is open source under the MIT license. Because the source is published, you can also run it in your own environment.
Pros & Cons
✅ Pros
- Finding, installing, and updating skills all happen through commands — no manual copying
- Versions and changelogs are preserved, making it easier to trace “when did this behavior change?”
- Pinning lets you protect a configuration that already works while updating other skills
- Vector search finds skills by intent, so you do not need to know the exact skill name
- MIT-licensed open source and free, with self-hosting as a remaining option
⚠️ Cons
- It is designed for the OpenClaw ecosystem, so skills will not necessarily run as-is in other agent environments
- Because anyone can publish to a public registry, you should review the contents (
SKILL.mdand any bundled code) before installing - Operation centers on the CLI, which adds a learning curve for people less comfortable with the command line
- Launched in March 2026, it is still young, and the number and quality of listed skills can vary

Who Is It For
- People building agents on OpenClaw who want to stop adding and updating skills by hand
- Developers who want to publish a skill they wrote so others can use it
- Teams that want a record of exactly which skill and which version they are running
- Anyone looking for concrete examples of what agents can be made to do
- People interested in registry design who want to read an open source implementation
Summary
ClawHub puts the “find it, install it, update it” loop for AI agent extensions onto familiar package-management rails. The decisive detail is that it brings version numbers, changelogs, and pinning — tools taken for granted in software development — to agent skills. If you already use OpenClaw, it will measurably cut the overhead of managing extensions; if you do not, it is still a useful case study in how skill distribution is being organized. Since it is free and open source, starting with a search costs nothing.
