icon-critique

Judge icons by their renders, never their source code. An SVG that looks right as markup routinely dies at 16 px — thin strokes vanish, closure gaps stop closing, counters fill in. This skill runs the render → critique → targeted-fix loop that every credible icon pipeline converged on, with a hard iteration cap.

When NOT to use

• Creating an icon from scratch → icon-draw (after icon-brief).
• Producing favicon/asset files or plain SVG→PNG conversion → icon-export.
• UI icon-set consistency reviews, page/UX critiques, code review.

Workflow

1. Lint before rendering. Renderers are an attack/crash surface — run the safe-subset linter on every input first and refuse to render files that fail its security checks (external refs, DOCTYPE, scripts, <image>):
