frontend-design-skills copilot-instructions.md is an instructions file for GitHub Copilot from flitzrrr/frontend-design-skills. It costs 499 tokens per session, scanned A, original, MIT.

A collection of reusable guidance files for designing websites, covering layout, user experience, typography, colors, accessibility, images, branding, and responsive behavior. Each skill is stored in its own file for coding assistants to consult.

In plain words
What is it for?
Planning and implementing web interfaces, including grids, navigation, forms, mobile layouts, font choices, color schemes, accessible markup, and media handling.
Why use it?
It helps an agent find the relevant design guidance before changing a website, so visual and accessibility decisions are not made ad hoc.

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-design-skills copilot-instructions.md 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.

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.
