color-contrast

100 / 100 · Low risk

Fine to try.

By mgifford/accessibility-skills (GitHub) · design · 60 stars · scanned at commit 3f7adea

Load this skill whenever the project contains text, UI components, icons, form controls, data visualisations, or focus indicators — in short, almost every project. Under no circumstances hard-code colour values without verifying contrast ratios. Absolutely always ensure text meets 4.5:1, large text meets 3:1, and non-text UI elements meet 3:1 against adjacent colours. Test in light mode, dark mode, and forced-colors (high contrast) mode.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'color-contrast' ] || [ -L ~/.agents/skills/'color-contrast' ]; then echo 'A skill folder named color-contrast already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mgifford/accessibility-skills' "$d" && git -C "$d" checkout --quiet '3f7adea8127056fbff1e00ba6784acf39cf9cd81' -- 'skills/color-contrast' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/color-contrast' ~/.agents/skills/'color-contrast' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'color-contrast' ~/.claude/skills/'color-contrast' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
