Once your skill works locally, you can share it with the community. Run clawhub publish from your skill directory. The CLI validates your SKILL.md, checks for a CHANGELOG.md, and uploads the package.
Versioning follows semver. Bump the version in your SKILL.md frontmatter before each publish. If you skip the version bump, the CLI rejects the upload. After publishing, your skill appears in clawhub list within a few minutes. Other people install it with npx clawhub install your-skill-name and receive future updates through clawhub update. Go ahead and try it with your hello-world skill.
