frontend

frontend is a plugin for Claude Code from fubits1/svelte-skills. Its manifest loads nothing; the 13 skills it bundles cost 538 tokens per session together, scanned A, original, MIT.

A plugin that sets working practices for frontend development, the part of an application users see and interact with. It covers measurement, editing, validation, testing, code style, and migration checks.

In plain words
What is it for?
Use it to guide pixel-level comparisons, frontend editing, validation, testing, code-style checks, and baseline creation when moving an interface between systems.
Why use it?
It provides a consistent way to check visual accuracy and frontend changes during development or migration.

Security

Grade A, and why

frontend 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 3d 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 it installs

The manifest is a name and a version. 13 skills travel with it, and installing the plugin installs all of them — 538 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
