Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

By sinhoneyy/master-skills (GitHub) · coding · 17 stars · scanned at commit 8e70b78

Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [<name>] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Use `scan` for a full audit with no diffing.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'accesslint-diff' ] || [ -L ~/.agents/skills/'accesslint-diff' ]; then echo 'A skill folder named accesslint-diff already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/sinhoneyy/master-skills' "$d" && git -C "$d" checkout --quiet '8e70b780359915a1f197ca37a1add2d4016115a2' -- 'skills/accesslint-diff' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/accesslint-diff' ~/.agents/skills/'accesslint-diff' && 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/'accesslint-diff' ~/.claude/skills/'accesslint-diff' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
