frontend

frontend is a skill for Claude Code, Codex from Mazalucas/El-DT-Lightweight-Army. It costs 30 tokens per session (478 once invoked), scanned A, original, MIT.

A set of rules for building website interfaces and reusable UI components. It covers React and Vite by default, while requiring the existing project’s framework and components to be respected when they differ.

In plain words
What is it for?
Use it to discover existing components, compose or implement screens, follow design handoffs, and check accessibility and performance. It also directs agents to reuse existing code before creating new pieces.
Why use it?
It helps keep new interface code consistent with the project, accessible to users, and less repetitive. It also clarifies when interface work belongs elsewhere, such as design specifications without implementation.

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

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 11d 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.
