Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
Hold a UI pixel-for-pixel steady through a change: PNG screenshots of the listed states before the first edit (baseline), then again at each green checkpoint, with differing pixels counted against pixel_tolerance (compare). Never edits a baseline. Use when: a plan phase has a Parity contract line, a refactor must leave the UI unchanged, 'check visual parity', 'did this change the UI'.

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/'check-visual-parity' ~/.claude/skills/'check-visual-parity' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
