SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Evaluating logos and brand identity systems requires deep design expertise that most teams lack, leading to marks that fail at small sizes, rely on trends, or never grow into coherent systems. This Skill provides structured critique and advisory guidance grounded in the methods of Paul Rand, Saul Bass, Aaron Draplin, Lance Wyman, and Milton Glaser. ## Core Features & Use Cases - Ten-Point Identity Evaluation: Score marks across identification power, conceptual clarity, systematic extensibility, real-world viability, timelessness, and craft using a structured rubric with severity levels. - Anti-Pattern Detection: Identify AI-generated mark tells such as gradient shields, conceptless monograms, complexity traps, and meaningless abstracts, with concrete fixes for each. - System and Color Guidance: Extend marks into full identity systems covering clear space, responsive variants, OKLCH palette construction, and tinted neutrals, with tool-specific advice for Figma, Illustrator, InDesign, Affinity, and HTML/CSS. - Use Case: A founder shares a logo concept and asks "does this work?" The Skill runs the blur/distance test, checks the favicon at 16x16, evaluates it against Rand's seven criteria, and returns a scored critique with prioritized recommendations. ## Quick Start Ask the assistant to critique your logo or identity concept against the ten-point evaluation framework and suggest improvements.

Frequently Asked Questions about identity

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I evaluate whether a logo design is good?▼

Evaluate a logo against Rand's seven criteria: distinctiveness, visibility, adaptability, memorability, universality, durability, and simplicity. Run practical tests including the blur test, the 16x16 favicon test, and a monochrome check to confirm the mark identifies at any size.

What are common mistakes in AI-generated logo designs?▼

AI-generated marks typically show gradient shields, conceptless initial monograms, excessive detail that fails at small sizes, trendy treatments that date quickly, and meaningless abstract shapes. Each anti-pattern maps to a specific failure against established identity principles.

How do I build a brand color palette with OKLCH?▼

Convert the primary brand color to OKLCH to find its hue angle, then build a lightness scale holding hue and chroma constant. Tint all neutrals with the brand hue at very low chroma (0.005-0.03) for cohesion, and verify contrast using the perceptually uniform lightness channel.

Can this skill generate logo designs for me?▼

No, this Skill never generates designs. It informs, critiques, and advises on identity work, providing evaluation frameworks, process methodology, and tool-specific guidance while the actual design work remains with the human designer.

How should a logo scale from favicon to billboard?▼

Define responsive variants: full lockup for formal contexts, mark-only for small sizes, and a simplified mark for favicons at 16x16 pixels. Test each variant at actual application sizes including social avatars, business cards, signage, and embroidery.
