design-lab

Conduct design interviews, generate five distinct UI variations in a temporary design lab, collect feedback, and produce implementation plans. Use when the user wants to explore UI design options, redesign existing components, or create new UI with multiple approaches to compare.

Quality

Content

27%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This skill is comprehensive in scope but severely undermined by its verbosity—it tries to be both a reference manual and an instruction set, resulting in a ~600-line document that explains many things Claude already knows. The workflow structure is solid with clear phases and abort handling, but lacks validation checkpoints for destructive/generative operations. Critical references to bundle files (DESIGN_PRINCIPLES.md, FeedbackOverlay template) don't exist, and the content that should be in those files is partially duplicated inline.

Suggestions

Split into multiple files: move interview question definitions to `interview-questions.md`, templates (Design Brief, Design Memory, Implementation Plan) to `templates/`, and variant generation guidelines to `variant-guidelines.md`, with clear one-level references from SKILL.md.

Cut at least 60% of the content by removing explanations of concepts Claude knows (what Tailwind config contains, what semantic HTML is, what WCAG means) and condensing interview questions to a compact table format rather than spelling out every option with descriptions.

Add explicit validation checkpoints: after generating lab files verify they parse/compile, after creating routes verify the route file exists, after cleanup verify no temp files remain. Missing validation for these generative/destructive operations is a significant gap.

Either include the referenced bundle files (DESIGN_PRINCIPLES.md, FeedbackOverlay.tsx template) or remove references to them—currently the skill references files that don't exist, which will cause confusion.

DimensionReasoningScore

Conciseness

Extremely verbose at ~600+ lines. Extensively explains concepts Claude already knows (what Tailwind is, how CSS variables work, what semantic HTML means, basic accessibility principles). The interview questions are spelled out in exhaustive detail with option descriptions that are obvious. The Design Memory template, implementation plan template, and design brief JSON could all be dramatically condensed. Much of this reads like documentation for a human developer rather than efficient instructions for Claude.

1 / 3

Actionability

Provides concrete directory structures, JSON schemas, and code snippets (e.g., FeedbackOverlay integration, route setup patterns). However, many critical pieces are pseudocode or templates rather than executable code—the variant generation is described abstractly ('restructure content hierarchy'), the FeedbackOverlay references a template file that doesn't exist in the bundle, and the actual component code for LabShell, fixtures, and variants is never provided. The feedback parsing format is well-specified but the actual implementation is left vague.

2 / 3

Workflow Clarity

The 8-phase workflow is clearly sequenced with good phase numbering and abort handling. However, validation checkpoints are largely missing—there's no step to verify the generated variants actually render, no validation that the route was created correctly, no check that the FeedbackOverlay is functional. The cleanup phase mentions safety rules but lacks a verification step to confirm all files were actually deleted. The error handling section exists but is vague ('check for port conflicts').

2 / 3

Progressive Disclosure

This is a monolithic wall of text with no bundle files to offload content to. It references `DESIGN_PRINCIPLES.md` and `design-and-refine/templates/feedback/FeedbackOverlay.tsx` but neither exists in the bundle. The interview question details, template contents, and variant generation guidelines could all be split into separate referenced files. Everything is inlined, making this extremely long and hard to navigate.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a strong skill description that clearly articulates a specific multi-step design exploration workflow. It uses third person voice correctly, provides concrete actions, and includes an explicit 'Use when...' clause with natural trigger terms. The description is concise yet comprehensive, making it easy for Claude to distinguish this skill from general UI development or design skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'conduct design interviews', 'generate five distinct UI variations in a temporary design lab', 'collect feedback', and 'produce implementation plans'. These are clear, actionable steps.

3 / 3

Completeness

Clearly answers both 'what' (conduct design interviews, generate UI variations, collect feedback, produce implementation plans) and 'when' with an explicit 'Use when...' clause covering three trigger scenarios.

3 / 3

Trigger Term Quality

Includes natural keywords users would say: 'UI design options', 'redesign existing components', 'create new UI', 'multiple approaches to compare', 'design interviews', 'feedback'. These cover common ways users would phrase design exploration requests.

3 / 3

Distinctiveness Conflict Risk

The combination of design interviews, five distinct variations in a 'temporary design lab', feedback collection, and implementation plans creates a very specific niche. The multi-variation comparison workflow is distinctive and unlikely to conflict with general UI or coding skills.
