## What it does

The plugin integrates the SourceKit-LSP language server into Claude Code. This gives the assistant structural code intelligence when inspecting files with the `.swift` extension.

The language server ships inside the Swift toolchain. On macOS, you obtain it through Xcode or via `brew install swift`. On Linux, the toolchain is downloaded directly from `swift.org`.

Without `sourcekit-lsp` available in your system `PATH`, the plugin cannot run. Make sure the Swift toolchain is installed before enabling it.

## Install

### Claude Code (native platform)

```
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-official
```

## When to use it
- enable SourceKit-LSP code intelligence for `.swift` files
- improve symbol navigation across Swift projects
- provide accurate type information to Claude Code

## Example prompts
- Find the definition of this struct across our Swift project
- Check the method signatures in `AppDelegate.swift`
- Locate where this protocol is declared in the `.swift` code
