openelectricity: Skill for Claude Code

.agents/skills/svelte-code-writer/SKILL.md

svelte-code-writer is a skill for Claude Code, Codex from opennem/openelectricity. It costs 68 tokens per session (524 once invoked), scanned A, a copy of svelte-code-writer, MIT.

A collection of command-line tools for looking up Svelte 5 documentation and analyzing Svelte code. Svelte is a framework for building web interfaces.

In plain words
What is it for?
Use it to list documentation sections, retrieve guidance, or run an autofixer on Svelte code and files, including checks for different Svelte versions.
Why use it?
It gives developers documentation-based help and automated checks when working with Svelte components or modules.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is opennem/openelectricity's own configuration. It tells Claude Code and Codex how to work on openelectricity itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openelectricity configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is npx @sveltejs/mcp svelte-autofixer ./src/lib/Component.svelte.

Reuse

Borrowing it

Nothing to install: this file belongs to opennem/openelectricity. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

svelte-code-writer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to svelte-code-writer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

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
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
