CLI tools for Svelte 5 documentation lookup and code analysis. MUST be used whenever creating, editing or analyzing 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.

CLI tools

You have access to @sveltejs/mcp CLI for Svelte-specific assistance. Use these commands via npx:

List documentation sections

npx @sveltejs/mcp list-sections

Lists all available Svelte 5 and SvelteKit documentation sections with titles and paths.

Get documentation

npx @sveltejs/mcp get-documentation "<section1>,<section2>,..."

Retrieves full documentation for specified sections. Use after list-sections to fetch relevant docs.

Example:

npx @sveltejs/mcp get-documentation "$state,$derived,$effect"

Svelte autofixer

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:

# 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

What it does

Provides CLI access to Svelte 5 documentation lookup and a code analyzer (svelte-autofixer) that detects issues in .svelte components and modules. Use this skill when writing, editing, or debugging Svelte components to check syntax and fetch relevant API docs on runes like $state and $derived.

Generated from the current SKILL.md.

Frequently asked

Does this skill work with Svelte 4 or only Svelte 5?
It targets Svelte 5 by default, but the svelte-autofixer tool accepts a --svelte-version flag to analyze code for Svelte 4.
Can I use this skill to look up SvelteKit documentation?
Yes. The list-sections command includes both Svelte 5 and SvelteKit documentation sections.
What does svelte-autofixer do?
It analyzes Svelte code and suggests fixes for common issues. You can pass either inline code or a file path.
How do I pass Svelte runes like $state to the CLI?
When passing code with runes via the terminal, escape the $ character as \$ to prevent shell variable substitution.
Should I use this skill with a specific agent?
The skill recommends executing it within the svelte-file-editor agent for optimal results, though it works standalone.
