 title: Overview
 ---
 
-The Svelte MCP ([Model Context Protocol](https://modelcontextprotocol.io/docs/getting-started/intro)) server can help your LLM or agent of choice write better Svelte code. It works by providing documentation relevant to the task at hand, and statically analysing generated code so that it can suggest fixes and best practices.
+The following pages will help you set up and use the AI tools officially maintained by the Svelte team.
 
-## Setup
+There are four tools, designed to help your agent write correct, robust Svelte code. They are designed to work together, but each can be used individually:
 
-The setup varies based on the version of the MCP you prefer — remote or local — and your chosen MCP client (e.g. Claude Code, Codex CLI or GitHub Copilot):
-
-- [local setup](local-setup) using `@sveltejs/mcp`
-- [remote setup](remote-setup) using `https://mcp.svelte.dev/mcp`
-
-## Usage
-
-To get the most out of the MCP server we recommend including the following prompt in your [`AGENTS.md`](https://agents.md) (or [`CLAUDE.md`](https://docs.claude.com/en/docs/claude-code/memory#claude-md-imports), if using Claude Code). This will tell the LLM which tools are available and when it's appropriate to use them.
-
-```md
-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.
-```
-
-If your MCP client supports it, we also recommend using the [svelte-task](prompts#svelte-task) prompt to instruct the LLM on the best way to use the MCP server.
+- [Instructions](instructions): small prompt always injected into your session to make your agent more aware of the available tools
+- [MCP Server](mcp): with tools, prompts and resources to give your agent more context, by pulling directly from the official Svelte documentation and using static analysis to correct common generative AI pitfalls
+- [Skills](skills): lazy-loaded descriptions that teach your agent Svelte best practices, and how to use the [`@sveltejs/mcp` cli](cli)
+- [Subagents](subagent): focused agents that can be invoked in parallel to execute atomic operations in a separate context window

+## svelte-task
+
+This prompt should be used whenever you are asking the model to work on a Svelte-related task. It will instruct the LLM which documentation sections are available, which tools to invoke, when to invoke them, and how to interpret the results.

+````markdown
+You are a Svelte expert tasked to build components and utilities for Svelte developers. If you need documentation for anything related to Svelte you can invoke the tool `get-documentation` with one of the following paths. However: before invoking the `get-documentation` tool, try to answer the users query using your own knowledge and the `svelte-autofixer` tool. Be mindful of how many section you request, since it is token-intensive!

+If you are not writing the code into a file, once you have the final version of the code ask the user if it wants to generate a playground link to quickly check the code in it and if it answer yes call the `playground-link` tool and return the url to the user nicely formatted. The playground link MUST be generated only once you have the final version of the code and you are ready to share it, it MUST include an entry point file called `App.svelte` where the main component should live. If you have multiple files to include in the playground link you can include them all at the root.

+
+The Svelte MCP ([Model Context Protocol](https://modelcontextprotocol.io/docs/getting-started/intro)) server can help your agent write better Svelte code. It works by providing relevant documentation, and statically analysing generated code so that it can suggest fixes and best practices.
+
+## Setup
+
+The setup varies based on the version of the MCP you prefer — remote or local — and your chosen MCP client (e.g. Claude Code, Codex CLI or GitHub Copilot):
+
+- [local setup](local-setup) using `@sveltejs/mcp`
+- [remote setup](remote-setup) using `https://mcp.svelte.dev/mcp`
+
+## Usage
+
+If your MCP client supports it, we also recommend using the [svelte-task](prompts#svelte-task) prompt to instruct the LLM on the best way to use the MCP server.

+
+The `@sveltejs/mcp` npm package normally launches the local `stdio` MCP server:
+
+```bash
+npx -y @sveltejs/mcp
+```
+
+If you invoke it with a subcommand, it behaves like a regular CLI and prints the result directly in your terminal instead. This is useful for agents, scripts and quick manual checks.
+
+## Usage
+
+```bash
+npx -y @sveltejs/mcp <command> [options]
+```
+
+Available commands:
+
+- `list-sections`
+- `get-documentation <sections>`
+- `svelte-autofixer <code_or_path>`
+
+You can learn more about the commands with
+
+```bash
+npx -y @sveltejs/mcp --help
+npx -y @sveltejs/mcp <command> --help
+npx -y @sveltejs/mcp --version
+```
+
+## `list-sections`
+
+Lists all available Svelte and SvelteKit documentation sections.
+
+```bash
+npx -y @sveltejs/mcp list-sections
+```
+
+The output is a structured text list of sections, including each section's title, `use_cases`, and documentation path. This is the same catalog the MCP tool uses before calling `get-documentation`.
+
+## `get-documentation`
+
+Fetches the full documentation for one or more sections.
+
+```bash
+npx -y @sveltejs/mcp get-documentation 'svelte/$state'
+# or
+npx -y @sveltejs/mcp get-documentation 'svelte/$state,svelte/await-expressions'
+```
+
+Each section can be matched by title or by documentation path. If a section cannot be found, the CLI returns an error plus similar matches when available.
+
+## `svelte-autofixer`
+
+Runs the Svelte autofixer against either inline code or a file path:
+
+```bash
+npx -y @sveltejs/mcp svelte-autofixer 'src/routes/+page.svelte'
+```
+
+If the argument is an existing path, the CLI reads the file automatically. Otherwise it treats the argument as raw Svelte code.
+
+Because most shells expand `$`, inline code should be quoted or escaped correctly. In practice, passing a file path is usually easier than passing source directly.
+
+Available options:
+
+- `--svelte-version <4|5>` - choose which Svelte version to validate against (defaults to `5`)
+- `--async` - enable async Svelte analysis for Svelte 5 projects
+
+The command prints an object with:
+
+- `issues`
+- `suggestions`
+- `require_another_tool_call_after_fixing`
+
+This makes it easy to use in an agentic loop: run the autofixer, apply fixes, then run it again until it reports no remaining issues or suggestions.

+# 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

+## `$state`
+
+Only use the `$state` rune for variables that should be _reactive_ — in other words, variables that cause an `$effect`, `$derived` or template expression to update. Everything else can be a normal variable.
+
+Objects and arrays (`$state({...})` or `$state([...])`) are made deeply reactive, meaning mutation will trigger updates. This has a trade-off: in exchange for fine-grained reactivity, the objects must be proxied, which has performance overhead. In cases where you're dealing with large objects that are only ever reassigned (rather than mutated), use `$state.raw` instead. This is often the case with API responses, for example.
+
+## `$derived`
+
+To compute something from state, use `$derived` rather than `$effect`:
+
+```js
+// do this
+let square = $derived(num * num);
+
+// don't do this
+let square;
+
+$effect(() => {
+	square = num * num;
+});
+```
+
+> [!NOTE] `$derived` is given an expression, _not_ a function. If you need to use a function (because the expression is complex, for example) use `$derived.by`.
+
+Deriveds are writable — you can assign to them, just like `$state`, except that they will re-evaluate when their expression changes.
+
+If the derived expression is an object or array, it will be returned as-is — it is _not_ made deeply reactive. You can, however, use `$state` inside `$derived.by` in the rare cases that you need this.
+
+## `$effect`
+
+Effects are an escape hatch and should mostly be avoided. In particular, avoid updating state inside effects.
+
+- If you need to sync state to an external library such as D3, it is often neater to use [`{@attach ...}`](references/@attach.md)
+- If you need to run some code in response to user interaction, put the code directly in an event handler or use a [function binding](references/bind.md) as appropriate
+- If you need to log values for debugging purposes, use [`$inspect`](references/$inspect.md)
+- If you need to observe something external to Svelte, use [`createSubscriber`](references/svelte-reactivity.md)
+
+Never wrap the contents of an effect in `if (browser) {...}` or similar — effects do not run on the server.
+
+## `$props`
+
+Treat props as though they will change. For example, values that depend on props should usually use `$derived`:
+
+```js
+// @errors: 2451
+let { type } = $props();
+
+// do this
+let color = $derived(type === 'danger' ? 'red' : 'green');
+
+// don't do this — `color` will not update if `type` changes
+let color = type === 'danger' ? 'red' : 'green';
+```
+
+## `$inspect.trace`
+
+`$inspect.trace` is a debugging tool for reactivity. If something is not updating properly or running more than it should you can add `$inspect.trace(label)` as the first line of an `$effect` or `$derived.by` (or any function they call) to trace their dependencies and discover which one triggered an update.
+
+## Events
+
+Any element attribute starting with `on` is treated as an event listener:
+
+```svelte
+<button onclick={() => {...}}>click me</button>
+
+<!-- attribute shorthand also works -->
+<button {onclick}>...</button>
+
+<!-- so do spread attributes -->
+<button {...props}>...</button>
+```
+
+If you need to attach listeners to `window` or `document` you can use `<svelte:window>` and `<svelte:document>`:
+
+```svelte
+<svelte:window onkeydown={...} />
+<svelte:document onvisibilitychange={...} />
+```
+
+Avoid using `onMount` or `$effect` for this.
+
+## Snippets
+
+[Snippets](references/snippet.md) are a way to define reusable chunks of markup that can be instantiated with the [`{@render ...}`](references/@render.md) tag, or passed to components as props. They must be declared within the template.
+
+```svelte
+{#snippet greeting(name)}
+	<p>hello {name}!</p>
+{/snippet}
+
+{@render greeting('world')}
+```
+
+> [!NOTE] Snippets declared at the top level of a component (i.e. not inside elements or blocks) can be referenced inside `<script>`. A snippet that doesn't reference component state is also available in a `<script module>`, in which case it can be exported for use by other components.
+
+## Each blocks
+
+Prefer to use [keyed each blocks](references/each.md) — this improves performance by allowing Svelte to surgically insert or remove items rather than updating the DOM belonging to existing items.
+
+> [!NOTE] The key _must_ uniquely identify the object. Do not use the index as a key.
+
+Avoid destructuring if you need to mutate the item (with something like `bind:value={item.count}`, for example).
+
+## Using JavaScript variables in CSS
+
+If you have a JS variable that you want to use inside CSS you can set a CSS custom property with the `style:` directive.
+
+```svelte
+<div style:--columns={columns}>...</div>
+```
+
+You can then reference `var(--columns)` inside the component's `<style>`.
+
+## Styling child components
+
+The CSS in a component's `<style>` is scoped to that component. If a parent component needs to control the child's styles, the preferred way is to use CSS custom properties:
+
+```svelte
+<!-- Parent.svelte -->
+<Child --color="red" />
+
+<!-- Child.svelte -->
+<h1>Hello</h1>
+
+<style>
+	h1 {
+		color: var(--color);
+	}
+</style>
+```
+
+If this is impossible (for example, the child component comes from a library) you can use `:global` to override styles:
+
+```svelte
+<div>
+	<Child />
+</div>
+
+<style>
+	div :global {
+		h1 {
+			color: red;
+		}
+	}
+</style>
+```
+
+## Context
+
+Consider using context instead of declaring state in a shared module. This will scope the state to the part of the app that needs it, and eliminate the possibility of it leaking between users when server-side rendering.
+
+Use `createContext` rather than `setContext` and `getContext`, as it provides type safety.
+
+## Async Svelte
+
+If using version 5.36 or higher, you can use [await expressions](references/await-expressions.md) and [hydratable](references/hydratable.md) to use promises directly inside components. Note that these require the `experimental.async` option to be enabled in `svelte.config.js` as they are not yet considered fully stable.
+
+## Avoid legacy features
+
+Always use runes mode for new code, and avoid features that have more modern replacements:
+
+- use `$state` instead of implicit reactivity (e.g. `let count = 0; count += 1`)
+- use `$derived` and `$effect` instead of `$:` assignments and statements (but only use effects when there is no better solution)
+- use `$props` instead of `export let`, `$$props` and `$$restProps`
+- use `onclick={...}` instead of `on:click={...}`
+- use `{#snippet ...}` and `{@render ...}` instead of `<slot>` and `$$slots` and `<svelte:fragment>`
+- use `<DynamicComponent>` instead of `<svelte:component this={DynamicComponent}>`
+- use `import Self from './ThisComponent.svelte'` and `<Self>` instead of `<svelte:self>`
+- use classes with `$state` fields to share reactivity between components, instead of using stores
+- use `{@attach ...}` instead of `use:action`
+- use clsx-style arrays and objects in `class` attributes, instead of the `class:` directive

+title: Overview
+---
+
+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/ai-tools/releases) of the repo, or find them in the [`tools/skills`](https://github.com/sveltejs/ai-tools/tree/main/tools/skills) folder.

+description: Specialized Svelte 5 code editor. MUST BE USED PROACTIVELY when creating, editing, or reviewing any .svelte file or .svelte.ts/.svelte.js module and MUST use the tools from the MCP server or the `svelte-file-editor` skill if they are available. Fetches relevant documentation and validates code using the Svelte MCP server tools.
+---
+
+You are a Svelte 5 expert responsible for writing, editing, and validating Svelte components and modules. You have access to the Svelte MCP server which provides documentation and code analysis tools. Always use the tools from the svelte MCP server to fetch documentation with `get_documentation` and validating the code with `svelte_autofixer`. If the autofixer returns any issue or suggestions try to solve them.
+
+If the MCP tools are not available you can use the `svelte-code-writer` skill to learn how to use the `@sveltejs/mcp` cli to access the same tools.
+
+If the skill is not available you can run `npx @sveltejs/mcp@latest -y --help` to learn how to use it.
+
+## Available MCP Tools
+
+### 1. list-sections
+
+Lists all available Svelte 5 and SvelteKit documentation sections with titles and paths. Use this first to discover what documentation is available.
+
+### 2. get-documentation
+
+Retrieves full documentation for specified sections. Accepts a single section name or an array of section names. Use after `list-sections` to fetch relevant docs for the task at hand.
+
+**Example sections:** `$state`, `$derived`, `$effect`, `$props`, `$bindable`, `snippets`, `routing`, `load functions`
+
+### 3. svelte-autofixer
+
+Analyzes Svelte code and returns suggestions to fix issues. Pass the component code directly to this tool. It will detect common mistakes like:
+
+- Using `$effect` instead of `$derived` for computations
+- Missing cleanup in effects
+- Svelte 4 syntax (`on:click`, `export let`, `<slot>`)
+- Missing keys in `{#each}` blocks
+- And more
+
+## Workflow
+
+When invoked to work on a Svelte file:
+
+### 1. Gather Context (if needed)
+
+If you're uncertain about Svelte 5 syntax or patterns, use the MCP tools:
+
+1. Call `list-sections` to see available documentation
+2. Call `get-documentation` with relevant section names
+
+### 2. Read the Target File
+
+Read the file to understand the current implementation.
+
+### 3. Make Changes
+
+Apply edits following Svelte 5 best practices:
+
+### 4. Validate Changes
+
+After editing, ALWAYS call `svelte-autofixer` with the updated code to check for issues.
+
+### 5. Fix Any Issues
+
+If the autofixer reports problems, fix them and re-validate until no issues remain.
+
+## Output Format
+
+After completing your work, provide:
+
+1. Summary of changes made
+2. Any issues found and fixed by the autofixer
+3. Recommendations for further improvements (if any)

+
+Since creating, editing or analyzing a Svelte file is an atomic operation we recommend creating a subagent that your main agent can invoke whenever it needs to interact with a Svelte component. Subagents use a separate context window, allowing them to fetch documentation, iterate with [`svelte-autofixer`](tools#svelte-autofixer) and write to the filesystem without wasting context in the main agent.
+
+Delegation should happen automatically when appropriate, but you can also explicitly request the subagent be used for Svelte-related tasks.
+
+You can write your own or take inspiration from the one available in the [`sveltejs/ai-tools`](https://github.com/sveltejs/ai-tools/tree/main/tools/agents) repository: a specialized subagent called `svelte-file-editor` designed for creating, editing, and reviewing Svelte files.

+
+The open source [repository](https://github.com/sveltejs/ai-tools) containing the code for the MCP server is also a Claude Code [plugin marketplace](https://code.claude.com/docs/en/discover-plugins).
+
+The marketplace allows you to install the `svelte` plugin which will give you the remote MCP server, [skills](skills) to instruct the LLM on how to properly write Svelte 5 code, and a specialized agent for editing Svelte files.
+
+If possible, we recommend that you instruct the LLM to execute MCP calls with the agent (you can explicitly mention an agent in your message to delegate work to it) when creating or editing `.svelte` files or `.svelte.ts`/`.svelte.js` modules — this will help save context by handling Svelte-specific tasks more efficiently.
+
+## Installation
+
+To add the repository as a marketplace, launch Claude Code and type the following:
+
+```bash
+/plugin marketplace add sveltejs/ai-tools
+```
+
+Then, install the Svelte plugin:
+
+```bash
+/plugin install svelte

+
+## Installation
+
+To install the plugin you can edit your [OpenCode config](https://opencode.ai/docs/config/) (either the global or the local one), adding `@sveltejs/opencode` to the list of plugins.

+
+Cursor has a [plugin system](https://cursor.com/docs/plugins) that can bundle rules, skills, agents, commands, MCP servers, and hooks.
+
+The Svelte plugin gives you the remote Svelte MCP server, Cursor [skills](skills), an always-on rule that tells the model how to use the Svelte MCP tools correctly, and the `svelte-file-editor` subagent for working on `.svelte` files and `.svelte.ts`/`.svelte.js` modules. The source is available in the [`sveltejs/ai-tools`](https://github.com/sveltejs/ai-tools/tree/main/plugins/cursor/svelte) repo.
+
+## Installation
+
+Install the plugin from the [Cursor Marketplace](https://cursor.com/marketplace/svelte) with the following command:
+
+```
+/add-plugin svelte
+```
+
+Plugins can be installed either for the current project or at user level.
+
+Once installed, Cursor will discover the plugin components automatically:
+
+- the Svelte MCP server is added from the plugin's `.mcp.json`
+- rules and skills appear in Cursor's rules UI
+- the `svelte-file-editor` agent becomes available in chat
+
+> [!NOTE] The Cursor CLI does not support plugins yet. Plugin support in [Cloud Agents](https://cursor.com/docs/cloud-agent) is limited to MCP servers.

+# @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
+
+Create `svelte.json` to customize how the plugin configures MCP, the Svelte subagent, instructions, and skills.

+
+### Supported Skill Names
+
+When using `skills.enabled` as an array, these built-in names are currently available:
+
+- `svelte-code-writer`
+- `svelte-core-bestpractices`
+
+### Config File Locations and Precedence
+
+The plugin reads from these files (lowest priority first, highest priority last):
+
+- `~/.config/opencode/svelte.json`
+- `$OPENCODE_CONFIG_DIR/svelte.json` (when `OPENCODE_CONFIG_DIR` is set)
+- `.opencode/svelte.json` in the current project
+
+If the same key is defined in multiple files, the later location overrides earlier ones.

+			"You are a Svelte 5 expert responsible for writing, editing, and validating Svelte components and modules. You have access to the Svelte MCP server which provides documentation and code analysis tools. Always use the tools from the svelte MCP server to fetch documentation with `get_documentation` and validating the code with `svelte_autofixer`. If the autofixer returns any issue or suggestions try to solve them.\n\nIf the MCP tools are not available you can use the `svelte-code-writer` skill to learn how to use the `@sveltejs/mcp` cli to access the same tools.\n\nIf the skill is not available you can run `npx @sveltejs/mcp@latest -y --help` to learn how to use it.\n\n## Available MCP Tools\n\n### 1. list-sections\n\nLists all available Svelte 5 and SvelteKit documentation sections with titles and paths. Use this first to discover what documentation is available.\n\n### 2. get-documentation\n\nRetrieves full documentation for specified sections. Accepts a single section name or an array of section names. Use after `list-sections` to fetch relevant docs for the task at hand.\n\n**Example sections:** `$state`, `$derived`, `$effect`, `$props`, `$bindable`, `snippets`, `routing`, `load functions`\n\n### 3. svelte-autofixer\n\nAnalyzes Svelte code and returns suggestions to fix issues. Pass the component code directly to this tool. It will detect common mistakes like:\n\n- Using `$effect` instead of `$derived` for computations\n- Missing cleanup in effects\n- Svelte 4 syntax (`on:click`, `export let`, `<slot>`)\n- Missing keys in `{#each}` blocks\n- And more\n\n## Workflow\n\nWhen invoked to work on a Svelte file:\n\n### 1. Gather Context (if needed)\n\nIf you're uncertain about Svelte 5 syntax or patterns, use the MCP tools:\n\n1. Call `list-sections` to see available documentation\n2. Call `get-documentation` with relevant section names\n\n### 2. Read the Target File\n\nRead the file to understand the current implementation.\n\n### 3. Make Changes\n\nApply edits following Svelte 5 best practices:\n\n### 4. Validate Changes\n\nAfter editing, ALWAYS call `svelte-autofixer` with the updated code to check for issues.\n\n### 5. Fix Any Issues\n\nIf the autofixer reports problems, fix them and re-validate until no issues remain.\n\n## Output Format\n\nAfter completing your work, provide:\n\n1. Summary of changes made\n2. Any issues found and fixed by the autofixer\n3. Recommendations for further improvements (if any)",

+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 Svelte 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.
