A design-planning skill that defines a project's visual rules in a DESIGN.md file, including typography, colours, layouts, motion, components, and accessibility.

Use it to create or review a design system, choose visual styles, assess responsive behaviour and accessibility, or guide a site or app redesign.

It gives frontend work a shared visual direction and helps catch inconsistent, hard-to-use, or inaccessible interface choices before implementation.

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	$0.00032	$0.01754
Opus 5.5	$0.00013	$0.00702
Sonnet 5.5	$0.00006	$0.00351
Haiku 4.5	$0.00003	$0.00175

Security

Grade A, and why

oma-design 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 today.

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.

Scheduling

Goal

Design specialist that defines, creates, and validates project design systems. DESIGN.md is the central artifact; all design work revolves around it.

Intent signature

User asks for design system, DESIGN.md, visual direction, typography, color, motion, accessibility, anti-pattern review, or component guidance.
User needs design decisions before frontend implementation or wants UI quality audited from a design perspective.

When to use

Defining or revising a project design system
Creating or auditing DESIGN.md
Selecting typography, color, layout, motion, or component direction
Reviewing UI work for responsive behavior, accessibility, and visual quality
Redesigning an existing site or app (preserve vs overhaul modes)
Using optional vendor inspiration from Stitch MCP or getdesign

When NOT to use

Implementing frontend components or application UI -> use oma-frontend
Planning product scope or task breakdown -> use oma-pm
Backend, database, infrastructure, or mobile implementation -> use the relevant specialist skill
General quality/security review outside visual, interaction, and accessibility concerns -> use oma-qa

Expected inputs

Product, brand, audience, platform, and UI/design problem
Existing .design-context.md, DESIGN.md, screenshots, references, or component constraints
Accessibility, responsive, language, and implementation constraints

Expected outputs

Design direction, revised DESIGN.md, audit findings, component guidance, or handoff notes
Responsive-first, WCAG-aware design recommendations
Optional vendor seed attribution when getdesign is used

outputs:
  - name: design-doc
    description: Updated DESIGN.md when the run materially advances the design system
    artifact: "DESIGN.md"
    required: false
  - name: design-context
    description: Refreshed .design-context.md snapshot when a discovery pass runs
    artifact: ".design-context.md"
    required: false

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.
