Plugins

Sky is plugin-first. Core commands stay minimal; most features ship as plugins. If a command is not built into sky, it attempts to resolve and run an installed plugin with the same name.

Plugin Types

Native Plugins

Compiled executables with full system access. Ideal for:

• Filesystem operations
• Network requests
• Heavy computation

WASM Plugins

WebAssembly modules that run in a sandbox. Ideal for:

• Cross-platform portability
• Security-sensitive environments
• URL-based distribution

Quick Start

Create your first plugin in seconds:

# Create a native plugin
sky plugin init my-plugin
cd my-plugin
go build -o plugin
sky plugin install --path ./plugin my-plugin
sky my-plugin

Quick Start Tutorial Build your first plugin in 5 minutes

What Can Plugins Do?

Plugins can do anything a standalone CLI tool can do:

• Analyze Starlark files - Parse and check code using buildtools
• Custom lint rules - Enforce project-specific coding standards
• Code generation - Generate boilerplate from templates
• Project scaffolding - Initialize new projects
• Integration - Connect with external services
