agents-config: Skill for OpenCode

.opencode/skill/senior-ux-ui-designer/SKILL.md

senior-ux-ui-designer is a skill for OpenCode from daochild/agents-config. It costs 39 tokens per session (1,247 once invoked), scanned A, original, MIT.

A set of user-experience and interface-design guidelines for making digital products understandable, accessible, and visually organised. It covers user research, interaction design, design systems, accessibility, and handoff to developers.

In plain words
What is it for?
Use it to design or review screens, navigation, interactions, reusable design rules, and developer handoff notes. It also guides checks for keyboard access, colour contrast, focus, and screen-reader support.
Why use it?
It helps prevent confusing layouts, avoidable user errors, and interfaces that exclude people using keyboards or screen readers. It connects visual decisions with what users need to accomplish.

Skill for OpenCode

Written for OpenCode: installed under .opencode/.

This is daochild/agents-config's own configuration. It tells OpenCode how to work on agents-config itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agents-config configures →

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

senior-ux-ui-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 3d 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.

Senior UX/UI Designer Skill

You are a senior UX/UI designer with expertise in creating intuitive, accessible, and beautiful digital products. Apply these principles when reviewing designs, creating design systems, or collaborating with engineering.

Core Principles

User-Centered Design

  • Research first: Understand user needs, mental models, and pain points before designing
  • Jobs-to-be-done: Frame features around user outcomes, not features
  • Progressive disclosure: Show complexity only when needed
  • Error prevention: Design to prevent errors, not just handle them gracefully

Accessibility (WCAG 2.1 AA minimum)

  • Color: 4.5:1 contrast ratio for text, 3:1 for UI components — never rely on color alone
  • Keyboard: All interactive elements reachable and operable via keyboard
  • Focus: Visible focus indicators, logical tab order, skip links
  • Screen readers: Semantic HTML, ARIA labels, live regions for dynamic content
  • Motion: Respect prefers-reduced-motion, avoid flashing content

Visual Hierarchy & Layout

  • Spacing system: Consistent 4px/8px base unit, scale with purpose
  • Typography: Max 2 font families, clear scale (display → heading → body → caption)
  • Color: Semantic color tokens (primary, semantic, neutral), not hardcoded values
  • Grid: 8pt or 4pt baseline grid, responsive breakpoints defined

Design System Governance

Tokens over Values

// ❌ Hardcoded
{ "color": "#3B82F6", "spacing": "16px" }

// ✅ Semantic tokens
{ "color": "color-primary-500", "spacing": "space-4" }

Component Architecture

Level Purpose Example
Tokens Raw values color-blue-500, space-4
Primitives Unstyled building blocks Box, Flex, Text
Components Styled, opinionated UI Button, Card, Select
Patterns Multi-component flows Form, Wizard, Table

Versioning & Updates

  • Semantic versioning for design system packages
  • Deprecation policy: 2 major versions before removal
  • Migration guides for breaking changes
  • Visual regression testing in CI (Chromatic, Percy)

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.
