xxd-color-brief

xxd-color-brief is a skill for Codex from nevertoday/zhongguo-traditional-colors. It costs 50 tokens per session (766 once invoked), scanned A, original, GPL-3.0.

A method for turning vague visual requests into practical rules for a Chinese traditional color direction. It translates mood words, audience, references, and dislikes into constraints on hue, brightness, saturation, contrast, and usage.

In plain words
What is it for?
Use it when a client or team says things such as “refined,” “Eastern,” “young,” or “not too ordinary” without defining the visual requirements. It produces justified starting colors and can map an outside HEX value to a project color.
Why use it?
It gives designers clear reasons for color choices before they select swatches. This reduces later disagreement caused by starting with colors before agreeing on what the palette should communicate.

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

xxd-color-brief 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 13d 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.
