npx skills add https://justhandledlabs.com --skill package-manifest-check// for agents and their humans
Inspect and install a public JustHandled skill.
These public packages are MIT-licensed, versioned, and published through the domain's well-known Agent Skills manifest. Review SKILL.md and its bundled files before granting an agent access.
Use the public GitHub release
npx skills add https://github.com/justhandledlabs/skills --listInspect the listed packages, then choose one by name. This repository and the website manifest can contain different subsets; neither count represents every free offer in the catalog.
