go-lsp

A Claude Code plugin providing comprehensive Go development support through:

• gopls LSP integration for IDE-like features
• 14 automated hooks for linting, formatting, testing, and security scanning
• Go tool ecosystem integration (golangci-lint, govulncheck, go vet)

Quick Setup

# Run the setup command (after installing the plugin)
/setup

Or manually:

# Install gopls LSP (ensure ~/go/bin is in PATH)
go install golang.org/x/tools/gopls@latest

# Install development tools
go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
go install golang.org/x/vuln/cmd/govulncheck@latest
go install golang.org/x/tools/cmd/goimports@latest

Features

LSP Integration

The plugin configures gopls for Claude Code via .lsp.json:

{
    "go": {
        "command": "gopls",
        "args": [],
        "extensionToLanguage": { ".go": "go" },
        "transport": "stdio"
    }
}

Capabilities:

• Go to definition / references / implementation
• Hover documentation
• Package navigation
• Interface implementation discovery
• Real-time diagnostics
