-Claude Skills are a set of Markdown files that live in your `.claude` folder (or that you can upload in your Claude web/desktop). They are automatically loaded by Claude when it thinks they are appropriate for the current task.
-
-With those markdown files you can steer the agent behaviours and, in our case, we teach him how to properly write Svelte 5 code. The advantage over the MCP server is that the relevant tokens are only loaded when they are needed (so if you ask the LLM to write a Typescript utility in a Svelte project it will not load the skill in the context).
-
-You can find the skill inside the [`sveltejs/mcp`](https://github.com/sveltejs/mcp/tree/main/plugins/svelte/skills) repo (it's in the `/plugins/svelte/skills` folder). You can also download the latest zip file from the [releases page](https://github.com/sveltejs/mcp/releases?q=svelte-code-writer) to load it in your Claude web/desktop or to extract it inside your `.claude` folder.
-
-If you are using Claude Code you can also install it through the [Svelte marketplace](plugin).

+
+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
+{
+	"$schema": "https://opencode.ai/config.json",
+	"plugin": ["@sveltejs/opencode"]
+}
+```
+
+That's it! You now have the Svelte MCP server, [skills](skills), and the [file editor subagent](opencode-subagent) configured for you.
+
+## Configuration
+
+The default configuration for the Svelte OpenCode plugin looks like this...
+
+```json
+{
+	"$schema": "https://raw.githubusercontent.com/sveltejs/mcp/refs/heads/main/packages/opencode/schema.json",
+	"mcp": {
+		"type": "remote",
+		"enabled": true
+	},
+	"subagent": {
+		"enabled": true
+	},
+	"skills": {
+		"enabled": true
+	}
+}
+```
+
+...but if you prefer, you can enable only the subagent, only the MCP, only the skills, 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`.

+
+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.

+
+This is the list of available skills provided by the Svelte MCP package. Skills are sets of instructions that AI agents can load on-demand to help with specific tasks.
+
+Skills are available in both the Claude Code plugin (installed via the marketplace) and the OpenCode plugin (`@sveltejs/opencode`). They can also be manually installed in your `.claude/skills/` or `.opencode/skills/` folder.
+
+You can download the latest skills from the [releases page](https://github.com/sveltejs/mcp/releases) or find them in the [`plugins/svelte/skills`](https://github.com/sveltejs/mcp/tree/main/plugins/svelte/skills) folder.
+
+## `svelte-code-writer`
+
+CLI tools for Svelte 5 documentation lookup and code analysis. MUST be used whenever creating or editing any Svelte component (.svelte) or Svelte module (.svelte.ts/.svelte.js). If possible, this skill should be executed within the svelte-file-editor agent for optimal results.

+# Svelte 5 Code Writer
+
+## CLI Tools
+
+You have access to `@sveltejs/mcp` CLI for Svelte-specific assistance. Use these commands via `npx`:
+
+### List Documentation Sections
+
+```bash
+npx @sveltejs/mcp list-sections
+```
+
+Lists all available Svelte 5 and SvelteKit documentation sections with titles and paths.
+
+### Get Documentation
+
+```bash
+npx @sveltejs/mcp get-documentation "<section1>,<section2>,..."
+```
+
+Retrieves full documentation for specified sections. Use after `list-sections` to fetch relevant docs.
+
+**Example:**
+
+```bash
+npx @sveltejs/mcp get-documentation "$state,$derived,$effect"
+```
+
+### Svelte Autofixer
+
+```bash
+npx @sveltejs/mcp svelte-autofixer "<code_or_path>" [options]
+```
+
+Analyzes Svelte code and suggests fixes for common issues.
+
+**Options:**
+
+- `--async` - Enable async Svelte mode (default: false)
+- `--svelte-version` - Target version: 4 or 5 (default: 5)
+
+**Examples:**
+
+```bash
+# Analyze inline code (escape $ as \$)
+npx @sveltejs/mcp svelte-autofixer '<script>let count = \$state(0);</script>'
+
+# Analyze a file
+npx @sveltejs/mcp svelte-autofixer ./src/lib/Component.svelte
+
+# Target Svelte 4
+npx @sveltejs/mcp svelte-autofixer ./Component.svelte --svelte-version 4
+```
+
+**Important:** When passing code with runes (`$state`, `$derived`, etc.) via the terminal, escape the `$` character as `\$` to prevent shell variable substitution.
+
+## Workflow
+
+1. **Uncertain about syntax?** Run `list-sections` then `get-documentation` for relevant topics
+2. **Reviewing/debugging?** Run `svelte-autofixer` on the code to detect issues
+3. **Always validate** - Run `svelte-autofixer` before finalizing any Svelte component

+# @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
+{
+	"$schema": "https://opencode.ai/config.json",
+	"plugin": ["@sveltejs/opencode"]
+}
+```
+
+That's it! You now have the Svelte MCP server and the file editor subagent configured automatically.
+
+## Features
+
+### Svelte MCP Server
+
+The plugin automatically configures the [Svelte MCP server](https://mcp.svelte.dev) which provides:
+
+- **list-sections** - Discover available Svelte 5 and SvelteKit documentation sections
+- **get-documentation** - Retrieve full documentation content for specific sections
+- **svelte-autofixer** - Analyze Svelte code and get issues/suggestions
+- **playground-link** - Generate Svelte Playground links with provided code
+
+### Svelte File Editor Subagent
+
+A specialized subagent (`svelte-file-editor`) that is automatically used when creating, editing, or reviewing `.svelte`, `.svelte.ts`, or `.svelte.js` files. It fetches relevant documentation and validates code using the Svelte MCP server tools.
+
+### Agent Instructions
+
+The plugin injects instructions that teach the agent how to effectively use the Svelte MCP tools.
+
+## Configuration
+
+The default configuration:
+
+```json
+{
+	"$schema": "https://raw.githubusercontent.com/sveltejs/mcp/refs/heads/main/packages/opencode/schema.json",
+	"mcp": {
+		"type": "remote",
+		"enabled": true
+	},
+	"subagent": {
+		"enabled": true
+	},
+	"instructions": {
+		"enabled": true
+	}
+}
+```
+
+### Configuration Options
+
+| Option                 | Type                    | Default    | Description                                                                      |
+| ---------------------- | ----------------------- | ---------- | -------------------------------------------------------------------------------- |
+| `mcp.type`             | `"remote"` \| `"local"` | `"remote"` | Use the remote server at `mcp.svelte.dev` or run locally via `npx @sveltejs/mcp` |
+| `mcp.enabled`          | `boolean`               | `true`     | Enable/disable the MCP server                                                    |
+| `subagent.enabled`     | `boolean`               | `true`     | Enable/disable the Svelte file editor subagent                                   |
+| `instructions.enabled` | `boolean`               | `true`     | Enable/disable agent instructions injection                                      |
+
+### Config File Location
+
+Place your configuration at one of these locations:
+
+- `~/.config/opencode/svelte.json` (global)
+- `$OPENCODE_CONFIG_DIR/svelte.json` (if `OPENCODE_CONFIG_DIR` is set, takes priority)

+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.

+---
+
+# Svelte 5 Code Writer
+
+## CLI Tools
+
+You have access to `@sveltejs/mcp` CLI for Svelte-specific assistance. Use these commands via `npx`:
+
+### List Documentation Sections
+
+```bash
+npx @sveltejs/mcp list-sections
+```
+
+Lists all available Svelte 5 and SvelteKit documentation sections with titles and paths.
+
+### Get Documentation
+
+```bash
+npx @sveltejs/mcp get-documentation "<section1>,<section2>,..."
+```
+
+Retrieves full documentation for specified sections. Use after `list-sections` to fetch relevant docs.
+
+**Example:**
+
+```bash
+npx @sveltejs/mcp get-documentation "$state,$derived,$effect"
+```
+
+### Svelte Autofixer
+
+```bash
+npx @sveltejs/mcp svelte-autofixer "<code_or_path>" [options]
+```
+
+Analyzes Svelte code and suggests fixes for common issues.
+
+**Options:**
+
+- `--async` - Enable async Svelte mode (default: false)
+- `--svelte-version` - Target version: 4 or 5 (default: 5)
+
+**Examples:**
+
+```bash
+# Analyze inline code (escape $ as \$)
+npx @sveltejs/mcp svelte-autofixer '<script>let count = \$state(0);</script>'
+
+# Analyze a file
+npx @sveltejs/mcp svelte-autofixer ./src/lib/Component.svelte
+
+# Target Svelte 4
+npx @sveltejs/mcp svelte-autofixer ./Component.svelte --svelte-version 4
+```
+
+**Important:** When passing code with runes (`$state`, `$derived`, etc.) via the terminal, escape the `$` character as `\$` to prevent shell variable substitution.
+
+## Workflow
+
+1. **Uncertain about syntax?** Run `list-sections` then `get-documentation` for relevant topics
+2. **Reviewing/debugging?** Run `svelte-autofixer` on the code to detect issues
+3. **Always validate** - Run `svelte-autofixer` before finalizing any Svelte component
