@sveltejs/opencode

OpenCode plugin for Svelte that provides the Svelte MCP server, a specialized file editor subagent and instruction files.

Installation

Add @sveltejs/opencode to your OpenCode config (either global or local):

``json
{
"$schema": "https://opencode.ai/config.json",
"plugin": ["@sveltejs/opencode"]
}
`

That's it! You now have the Svelte MCP server and the file editor subagent configured automatically.

Features

$3

The plugin automatically configures the Svelte MCP server which provides:

- list-sections - Discover available Svelte 5 and SvelteKit documentation sections
- get-documentation - Retrieve full documentation content for specific sections
- svelte-autofixer - Analyze Svelte code and get issues/suggestions
- playground-link - Generate Svelte Playground links with provided code

$3

A specialized subagent (svelte-file-editor) that is automatically used when creating, editing, or reviewing .svelte, .svelte.ts, or .svelte.js files. It fetches relevant documentation and validates code using the Svelte MCP server tools.

$3

The plugin injects instructions that teach the agent how to effectively use the Svelte MCP tools.

Configuration

The default configuration:

`json
{
"$schema": "https://raw.githubusercontent.com/sveltejs/mcp/refs/heads/main/packages/opencode/schema.json",
"mcp": {
"type": "remote",
"enabled": true
},
"subagent": {
"enabled": true
},
"instructions": {
