frontend

frontend is a skill for Claude Code, Codex from jh941213/codex-lattice. It costs 92 tokens per session (784 once invoked), scanned A, original, MIT.

A workflow for planning and building frontend interfaces—the visible parts of websites and applications—using defined visual styles, components, layouts, and responsive behavior.

In plain words
What is it for?
Use it for landing pages, dashboards, pages, UI components, and other frontend work. It is not intended for backend APIs, databases, or command-line tools.
Why use it?
It gives interface work a design phase before implementation and checks the result for type errors, build success, mobile layout, and accessibility.

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.

Fable 5 $0.00092 $0.00784
Opus 5 $0.00046 $0.00392
Sonnet 5 $0.00018 $0.00157

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 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.
