svelte

svelte is a skill for Claude Code, Codex from cesdperez/llmfiles. It costs 78 tokens per session (2,341 once invoked), scanned A, original, no licence file.

A development guide for Svelte 5 and SvelteKit 2.9+, tools for building web interfaces and web applications. It covers components, routes, data loading, form handling, and Svelte’s runes such as $state and $props.

In plain words
What is it for?
Use it to write Svelte components, create SvelteKit routes, implement load functions and form actions, and work with .svelte files or runes.
Why use it?
It provides relevant practices when working with Svelte code, helping avoid mistakes caused by using patterns from older versions or unrelated frameworks.

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 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 5d 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.

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.
