# Install Skill Doctor with npm, cargo or a prebuilt binary

> Install the Skill Doctor CLI globally with npm or cargo, download a signed prebuilt binary, or build it from source.

Skill Doctor ships as one binary for Linux (musl), macOS and Windows, on `x86_64` and `aarch64`. Pick the
channel that fits your setup.

> [tab] npm
>
> ```bash theme={null}
> npm install -g @security.kalarislabs/skill-doctor
> skill-doctor scan ./examples/hello-skill
> ```
>
> The package downloads the matching binary during `postinstall`. Set `SKILL_DOCTOR_SKIP_DOWNLOAD=1`
> to skip that step, for example when you build from source.

> [tab] cargo
>
> ```bash theme={null}
> cargo install skill-doctor --locked --features mcp
> skill-doctor scan ./examples/hello-skill
> ```
>
> > [!WARNING]
> >
> > Keep `--features mcp` if you want `skill-doctor mcp`. The crate's default feature set is empty, so a
> > plain `cargo install skill-doctor` builds without the MCP server.

> [tab] Prebuilt binary
>
> Download a stripped binary for your platform from
> [GitHub Releases](https://github.com/KalarisLabs/Skill-Doctor/releases/tag/v0.1.0), then
> [verify it](https://docs.kalarislabs.com/skill-doctor/reference/verify-releases.md) before you put it on your `PATH`.
>
> On macOS, remove the Gatekeeper quarantine flag if the binary will not open:
>
> ```bash theme={null}
> xattr -d com.apple.quarantine skill-doctor
> ```

> [tab] From source
>
> Requires Rust 1.93.0 or later.
>
> ```bash theme={null}
> git clone https://github.com/KalarisLabs/Skill-Doctor && cd Skill-Doctor
> cargo install --path crates/skill-doctor-cli --locked --features mcp
> skill-doctor scan ./examples/hello-skill
> ```
