design-system: Skill for Claude Code

.agents/skills/ui-doctor/SKILL.md

ui-doctor is a skill for Claude Code, Codex from iress/design-system. It costs 79 tokens per session (5,214 once invoked), scanned A, original, Apache-2.0.

A review process for checking an application's interface against design-system rules, accessibility guidance, usability principles, and cognitive-load concerns. Cognitive load means how much mental effort users need to understand and use a screen.

In plain words
What is it for?
Use it to review pages, components, forms, or interface code for WCAG 2.1 AA accessibility, usability heuristics, design-token consistency, and progressive disclosure.
Why use it?
It finds barriers such as inaccessible controls, inconsistent components, confusing flows, and screens that overwhelm users. The result is an actionable report with prioritised recommendations.

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

ui-doctor 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.

Skill: UI Doctor

Audit and review application UI for IDS compliance, accessibility, usability, and cognitive load. This skill helps AI agents perform comprehensive UI reviews covering component usage, accessibility (WCAG), usability heuristics (Nielsen's 10), cognitive load, and progressive disclosure — then produce actionable reports with prioritised recommendations.

When to Use

Activate this skill when the user says things like:

  • "Review this page / component / file for accessibility"
  • "Check the usability of this UI"
  • "Audit this for IDS compliance"
  • "This feels like too much cognitive load"
  • "Are we following IDS guidelines?"
  • "Check for a11y issues"
  • "Review this UI"
  • "Is this form accessible?"
  • "Can you do a UX review?"

Or more generally:

  • Reviewing application UI code for IDS compliance
  • Validating accessibility (WCAG 2.1 AA)
  • Assessing usability and cognitive load
  • Evaluating design token usage and consistency
  • Generating a UI health report with a compliance score
  • Providing recommendations to improve UX, accessibility, and IDS adoption

Audit Modes

Default: Quick UX Review. Use this unless the user specifically asks for accessibility or full compliance. Escalate to a more thorough mode if the quick review reveals significant issues.

Quick UX Review (default)

Use when the user asks for a general UI review, usability check, or "does this look right?"

  1. Cognitive load & information architecture — Is the UI overwhelming? Are there too many items, options, or actions visible at once?
  2. Usability heuristics — Evaluate against Nielsen's 10 (see audit checklist § Usability Heuristics)
  3. Button hierarchy & layout consistency — One primary per section, consistent spacing
  4. Quick component scan — Are obvious raw HTML elements used where IDS components exist?

Accessibility Review

Use when the user asks about a11y, WCAG, keyboard navigation, or screen reader support.

  1. Form accessibility — Labels, required indicators, validation messages, id/htmlFor pairing
  2. Keyboard & focus — Skip links, focus trapping in modals/slideouts, visible focus indicators
  3. Screen reader — ARIA landmarks, dynamic content announcements, accessible names on interactive elements
  4. Colour & contrast — WCAG AA contrast ratios, no reliance on colour alone
  5. Cognitive load — Progressive disclosure, information density (see audit checklist § Cognitive Load)

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.
