**Fundamentals**

# **skills.sh — the Agent Skills CLI**

skills.sh is the open-source CLI for installing Agent Skills into Claude and other agents. Use it to add the Webhook Relay skills with a single command.

## [What is skills.sh?](#what-is-skillssh)

[skills.sh](https://www.skills.sh) is the open-source command-line tool for installing [Agent Skills](https://webhookrelay.com/docs/skills-cli/docs/skills/) — the small instruction packs that teach Claude (and other skill-aware agents) how to perform a specific task. You run it with `npx skills`, point it at a GitHub repository, and it downloads the skills and drops them into your agent's skills directory.

In short, it:

- **Installs skills from any GitHub repo** with one command — `npx skills add <owner>/<repo>`.
- **Works per-project or globally** — keep skills next to a single project, or install with `-g` so every agent on your machine can use them.
- **Is open source and free** — no account, no registry lock-in; it just pulls the skill files from the repository you point it at.

It's the fastest way to install the Webhook Relay skills, which is why the [Agent Skills](https://webhookrelay.com/docs/skills-cli/docs/skills/) docs use it.

## [Add the Webhook Relay skills](#add-the-webhook-relay-skills)

The Webhook Relay skills live in the open-source [webhookrelay/skills](https://github.com/webhookrelay/skills) repository. Add all of them with:

```
npx skills add webhookrelay/skills
```

Install globally so every agent on your machine picks them up:

```
npx skills add webhookrelay/skills -g
```

Or install just one skill with `--skill`:

```
npx skills add webhookrelay/skills --skill webhook-debug
```

Once installed, your agent can drive Webhook Relay directly — forwarding webhooks, transforming them, debugging incoming requests, opening tunnels, scheduling recurring webhooks, and receiving, parsing and transforming inbound email. See [Agent Skills](https://webhookrelay.com/docs/skills-cli/docs/skills/) for the full list of skills and what each one does.

> Most skills use the `relay` CLI — see [CLI installation](https://webhookrelay.com/docs/skills-cli/docs/installation/cli/), then run `relay login`. The `webhook-debug` skill needs nothing but `curl`.

## [Other ways to install](#other-ways-to-install)

skills.sh is one distribution channel. The same skills are also available via the Claude Code plugin marketplace, the [ClawHub](https://webhookrelay.com/docs/skills-cli/docs/clawhub/) registry, or a manual copy from the repo — see [Agent Skills](https://webhookrelay.com/docs/skills-cli/docs/skills/) for every option.
