Svelte Code Writer

sveltejs/ai-tools-svelte-svelte-code-writer

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.

This is a copy. The original lives at sveltejs/svelte-code-writer.

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

  • Uncertain about syntax? Run list-sections then get-documentation for relevant topics
  • Reviewing/debugging? Run svelte-autofixer on the code to detect issues
  • Always validate - Run svelte-autofixer before finalizing any Svelte component

How to use it

Copy the folder

Take sveltejs/ai-tools-svelte-svelte-code-writer from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
