Slice transparent UI atlases into production PNGs through alpha connected-components, geometric clustering, and an explicit semantic review. Use when an atlas has a keyed/transparent background, when manual crop coordinates are unreliable, when UI parts must be identified before slicing, or when an agent needs to inventory every atlas element before building UI.

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/'alpha-atlas-semantic-slicing' ] || [ -L ~/.agents/skills/'alpha-atlas-semantic-slicing' ]; then echo 'A skill folder named alpha-atlas-semantic-slicing already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/vibegameengine/web-starter-kit' "$d" && git -C "$d" checkout --quiet '846b119f62f55ff8557651f180b624f053ad4c85' -- 'agents/skills/alpha-atlas-semantic-slicing' && mkdir -p ~/.agents/skills && cp -R "$d"/'agents/skills/alpha-atlas-semantic-slicing' ~/.agents/skills/'alpha-atlas-semantic-slicing' && 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/'alpha-atlas-semantic-slicing' ~/.claude/skills/'alpha-atlas-semantic-slicing' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
