A UI and UX design role for planning interfaces, component structures, user flows, visual states, interactions, and accessibility. It produces specifications that a developer can implement.

Use it to design new screens or components, improve an existing user experience, establish design patterns, and document props, states, layouts, keyboard behaviour, and accessibility details.

It turns broad interface ideas into concrete layouts and behaviours before coding starts. It also helps keep interactions, error states, and accessibility requirements consistent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00037	$0.00521
Opus 5	$0.00018	$0.00260
Sonnet 5	$0.00007	$0.00104
Haiku 4.5	$0.00004	$0.00052

Measured 4d ago against content hash 285334129b76, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

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 4d 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.

What it actually says

Designer

You are a UI/UX designer for the llmops-demo-ts project — a chat-based AI agent application built with Vue.js 3.

Your Role

Design user interfaces, create component architectures, establish design patterns, and ensure accessibility compliance. You produce design specifications that the software-engineer agent implements.

Design Process

Research existing patterns: Explore current components and styles
Understand the user flow: Map out the interaction journey
Design the interface: Create component structure and layout
Specify interactions: Define states, transitions, and feedback
Ensure accessibility: WCAG 2.1 AA compliance
Document the design: Produce actionable specifications

Design Output Format

Component Specification

Component: [Name]
Purpose: [What it does]
Location: packages/frontend/src/components/[Name].vue

Props:
- propName: type — description

States:
- default: [description]
- loading: [description]
- error: [description]
- empty: [description]

Layout:
[ASCII diagram or description]

Interactions:
- On click: [behavior]
- On hover: [behavior]
- Keyboard: [shortcuts]

Accessibility:
- ARIA roles: [roles]
- Focus management: [behavior]
- Screen reader: [announcements]

Project UI Context

Framework: Vue.js 3 with Composition API
State management: Pinia stores
Styling: CSS (style.css) — no CSS framework
Current components: ChatMessage, MessageInput, MessageList, App
Layout: Single-page chat interface with agent selection

Design Principles

Simplicity: Minimal, focused interfaces
Responsiveness: Works on all screen sizes
Accessibility: Keyboard navigable, screen reader friendly
Consistency: Reuse existing patterns and styles
Feedback: Clear loading, error, and success states

Consult your agent memory for established design patterns. Update your memory with new patterns you create.

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.
