Start with Git
Commit or stash the project before adding a capability so the change is easy to inspect.
CLI REFERENCE Install the capability
Install the capability
where the work lives.
Use Skilly CLI from the repository where your agent runs. The command keeps the source and skill name explicit, so you can review exactly what you are adding.
One command to get started.
Every skill detail page includes an install command built from its indexed source and skill slug. Copy it, switch to your project terminal, and run it with the agent harness you use there.
TERMINAL
npx skilly-cli add owner/repo --skill skill-nameThe exact command may include the publisher’s repository and the selected skill name.
Keep the source visible.
| Part | Meaning | Example |
|---|---|---|
npx skilly-cli | Run Skilly CLI without a global install. | npx skilly-cli |
add | Add a skill to the current project. | add |
owner/repo | Identify the source repository. | anthropics/skills |
--skill | Select the skill within that source. | --skill frontend-design |
Install with a little context.
Read the publisher
Open the source link on the detail page and check the instructions, tools, and permissions the skill expects.
Run the narrowest command
Install one skill at a time and keep it in the project where it is needed.
Skilly is a discovery index. Skilly CLI installs the skill, while your agent harness determines where it is loaded and what tools it can access.
When an install does not work.
The command cannot find the repository
Check the source link on the skill page and make sure the repository is public or available to the credentials used by your harness.
The agent does not see the new skill
Restart the agent session or reopen the project. Harnesses discover project files at different times.
I want to inspect the skill first
Open the skill detail page and read the full indexed SKILL.md before copying its command. You can also open the original repository from the source link.
