zed-editor

Overview

Build extensions for the Zed editor — high-performance, multiplayer code editor built in Rust.

Extensions are Rust crates compiled to WebAssembly that run in a sandboxed Wasmtime environment. They can provide languages, themes, debuggers, snippets, MCP servers, and AI slash commands.

Top-Level Metadata

What: This skill covers creating Zed Editor extensions — Rust/Wasm plugins for language support, themes, debuggers, MCP servers, slash commands, and more. Includes extension manifest structure, language server integration, tree-sitter grammar development, and publishing workflows.

Why: Extend Zed to add custom language support, debugging capabilities, AI-powered features, and personalization through themes and snippets. Zed's sandboxed architecture allows safe extension development without compromising core editor stability.

When: Use this skill when developing extensions for Zed, whether for production use, personal productivity tools, or contributing to the Zed ecosystem. Ideal for language developers, editor enthusiasts, and Rust developers building Wasm-based extensions.
