+title: Overview
+---
+
+OpenCode has a [plugin system](https://opencode.ai/docs/plugins/) that allows developers to add MCP servers, agents and commands programmatically. Svelte has an OpenCode plugin published under `@sveltejs/opencode`.
+
+## Installation
+
+To install the plugin in OpenCode you can edit your [OpenCode config]() (either the global or the local one), adding `@sveltejs/opencode` to the list of plugins.
+
+```json
+{
+	"$schema": "https://opencode.ai/config.json",
+	"plugin": ["@sveltejs/opencode"]
+}
+```
+
+That's it! You now have the Svelte MCP server and the [file editor subagent](opencode-subagent) configured for you.
+
+## Configuration
+
+The default configuration for the Svelte OpenCode plugin looks like this...
+
+```json
+{
+	"$schema": "https://raw.githubusercontent.com/sveltejs/mcp/refs/heads/main/packages/opencode/schema.json",
+	"mcp": {
+		"type": "remote",
+		"enabled": true
+	},
+	"subagent": {
+		"enabled": true
+	}
+}
+```
+
+...but if you prefer, you can enable only the subagent, only the MCP, or configure the kind of MCP server you want to use (`local` or `remote`).
+
+You can place this file in `~/.config/opencode/svelte.json` or, if you have an `OPENCODE_CONFIG_DIR` environment variable specified, at `$OPENCODE_CONFIG_DIR/svelte.json`.

+---
+title: Subagent
+---
+
+The Svelte plugin includes a specialized subagent called `svelte-file-editor` designed for creating, editing, and reviewing Svelte files.
+
+## Benefits
+
+The subagent has access to its own context window, allowing it to fetch the documentation, iterate with the `svelte-autofixer` tool and write to the file system without wasting context in the main agent.
+
+The delegation should happen automatically when appropriate, but you can also explicitly request the subagent be used for Svelte-related tasks.

+You are able to use the Svelte MCP server, where you have access to comprehensive Svelte 5 and SvelteKit documentation. Here's how to use the available tools effectively:
+
+## Available MCP Tools:
+
+### 1. list-sections
+
+Use this FIRST to discover all available documentation sections. Returns a structured list with titles, use_cases, and paths.
+When asked about Svelte or SvelteKit topics, ALWAYS use this tool at the start of the chat to find relevant sections.
+
+### 2. get-documentation
+
+Retrieves full documentation content for specific sections. Accepts single or multiple sections.
+After calling the list-sections tool, you MUST analyze the returned documentation sections (especially the use_cases field) and then use the get-documentation tool to fetch ALL documentation sections that are relevant for the user's task.
+
+### 3. svelte-autofixer
+
+Analyzes Svelte code and returns issues and suggestions.
+You MUST use this tool whenever writing Svelte code before sending it to the user. Keep calling it until no issues or suggestions are returned.
+
+### 4. playground-link
+
+Generates a Svelte Playground link with the provided code.
+After completing the code, ask the user if they want a playground link. Only call this tool after user confirmation and NEVER if code was written to files in their project.
