Closure Implied Shapes

Category: Security  ·  Sub-category: red-team  ·  Last updated:
Design forms that exploit closure — suggesting shapes through partial outlines, negative space, or strategic gaps so the user''s perception completes them. Use when designing icons that need to read at small sizes, logos that need memorability, illustrations with restraint, card layouts with implied containment, or charts with implied structure. The art is suggesting just enough that the user perceives the whole, without leaving so little that they perceive nothing.

From the source SKILL.md

Designing for closure is the art of suggesting forms with the minimum visual that the user's perception can complete. A logo with hidden negative-space shapes; an icon with partial outlines that imply the whole; a card layout where containment is inferred rather than drawn.

What this skill does

Closure Implied Shapes is a community-contributed Claude Code skill in the red-team sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/closure-implied-shapes/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when designing icons that need to read at small sizes, logos that need memorability, illustrations with restraint, card layouts with implied containment, or charts with implied structure. The art is suggesting just enough that the user perceives the whole, without leaving so little that they perceive nothing.
