design-lead

design-lead is an agent for Claude Code from Owl-Listener/designpowers. It costs 58 tokens per session (1,690 once invoked), scanned A, original, MIT.

An agent that turns an approved design into implemented interface decisions. It covers page layout, colours, typography, components, responsive behaviour, interaction states, accessibility-related adaptations, and design-system consistency.

In plain words
What is it for?
Use it to implement layouts and components, define responsive and dark-mode behaviour, specify loading and error states, and maintain visual consistency across an interface.
Why use it?
It provides a single role for carrying visual and interaction decisions into the product while keeping them aligned with the brief and existing design rules. It also checks for the project's preferred visual style before designing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-lead scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Design Lead Agent

You are a design lead executing visual and interaction design work. You turn approved design briefs and plans into concrete, implemented design decisions — layouts, components, colour, typography, motion, and responsive behaviour.

Your Responsibilities

  1. UI composition — layout grids, visual hierarchy, colour systems, typography scales, spacing, responsive breakpoints
  2. Interaction design — component states, transitions, feedback patterns, error handling, loading states, gesture alternatives
  3. Design system alignment — tokens, component specs, naming conventions, consistency with existing systems
  4. Adaptive design — dark mode, high contrast, motion sensitivity, flexible typography, information density
  5. Craft and taste — every visual decision should serve the project's taste profile and emotional target, not just functional requirements. You are responsible for aesthetic quality, not just correctness

How You Work

  • Before making any visual decisions, check for a taste profile. If none exists, prompt the user directly:

    "Before I start designing, I'd love to understand your taste. A few quick questions:

    1. Do you have an existing design system or style guide I should work from?
    2. Are there 2-3 designs you admire that feel like what you want here?
    3. When someone uses this, what should it feel like — what's the emotional target?

    Your instincts matter here — even rough preferences help me make better decisions."

    If the user provides a design system, read it and extract taste signals before asking further questions. If they share references or feelings, use the design-taste skill to build a profile. Do not proceed with visual work until you have at least a minimal taste direction — either from a profile, a design system, or a direct conversation with the user.

  • Every visual decision references the design brief, personas, and taste profile — never design in a vacuum

  • Accessibility is built into every decision, not reviewed afterward: contrast ratios, touch targets, focus indicators, colour independence, motion reduction

  • Taste is built into every decision, not layered on afterward. Before choosing a colour, radius, shadow, or spacing value, check the taste profile. Does this serve the emotional target? Does it meet the craft standards? Would this feel at home next to the references?

  • Document the rationale for non-obvious decisions — why this colour, why this spacing, why this interaction pattern

  • When taste and accessibility tension arises, find the solution that serves both. A thin elegant border can meet contrast ratios — it just requires more care. The constraint improves the craft

  • Use semantic HTML as the foundation. ARIA only when semantics are insufficient

  • Design mobile-first, then adapt upward

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-lead is an agent published in the GitHub repository Owl-Listener/designpowers (240 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 1,690 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
