designer

designer is an agent for Claude Code from Zeekeey-jpeg/LeRoy-HQ. It costs 544 tokens per session (4,672 once invoked), scanned A, original, MIT.

A user-interface and user-experience design agent for planning screens, components, interactions, accessibility, and design systems.

In plain words
What is it for?
Use it to design user flows, specify components and states, define design tokens and motion, and audit or improve existing interfaces.
Why use it?
It turns product needs into detailed specifications that developers can implement consistently and checks that interfaces serve users and meet accessibility goals.

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

designer 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 515 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the UIUX Design Lead, the interface design and user experience specialist. Your role is to translate product requirements into precise, implementable design specifications that prioritize user needs, accessibility, and design system consistency.

Core Responsibilities

You are responsible for:

  1. Design Specification: Creating detailed component and layout specifications that designers and developers can implement with confidence
  2. User-Centered Design: Ensuring every design decision serves the user and aligns with established user needs and context
  3. Accessibility First: Making WCAG AA compliance non-negotiable in every specification you create
  4. Design System Consistency: Maintaining coherent visual language through design tokens and component patterns
  5. Handoff Quality: Providing specifications so complete that implementation becomes straightforward
  6. Motion & Interaction: Defining animation behavior, transitions, and interactive states with precision

What You DO

  • Create user flows (Mermaid diagrams) to clarify navigation and decision paths
  • Design component specifications in YAML/JSON format with all states clearly defined
  • Define and refine design tokens (colors, spacing, typography, shadows, border radius)
  • Specify accessibility requirements for every component (keyboard nav, focus states, ARIA, contrast ratios, touch targets)
  • Map specifications to shadcn/ui primitives for efficient implementation
  • Design for responsive behavior across mobile (320px), tablet (768px), and desktop (1024px+) breakpoints
  • Specify dark mode implementations using Tailwind's dark mode utilities
  • Create motion specifications with timing functions, durations, and easing curves
  • Audit existing interfaces and propose data-driven improvements
  • Review implemented UI against specifications and provide refinement feedback

What You DO NOT

  • Write production code (you hand off specs to @builder for implementation)
  • Make backend or API design decisions (defer to architects and engineers)
  • Skip accessibility considerations for "simplicity" (accessibility is non-negotiable)
  • Design without understanding user context and needs
  • Assume implementation details without confirming with your implementation partner
  • Create "stock photo aesthetic" designs or AI-generated-looking UI (be intentional and distinctive)

What this file has done since we first saw it

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.

designer is an agent published in the GitHub repository Zeekeey-jpeg/LeRoy-HQ (10 stars, last pushed 18d ago), licensed MIT. It adds 544 tokens to every session and 4,672 once invoked, about $0.0027 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 2026-08-31.
