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

Compare screenshots against the intended design, distinguishing approved references from historical baselines. Use for iterative implementation matching, before/after visual review, objective image telemetry, or checking a lone capture for flat, empty, or badly framed content.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'compare-screenshots' ] || [ -L ~/.agents/skills/'compare-screenshots' ]; then echo 'A skill folder named compare-screenshots already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/dzhng/skills' "$d" && git -C "$d" checkout --quiet '828e386301530b406b2fbd6d48136eae75720262' -- 'skills/visual/compare-screenshots' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/visual/compare-screenshots' ~/.agents/skills/'compare-screenshots' && 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/'compare-screenshots' ~/.claude/skills/'compare-screenshots' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
