A UI design and review workflow for creating or describing interfaces, or checking an existing interface for layout, accessibility, content, styling, and loading states.

Use it to plan a new interface or review an existing one for usability and visual consistency.

It provides a structured way to find design problems and account for different screen sizes and unfinished or delayed content.

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	$0.00048	$0.11191
Opus 5.5	$0.00019	$0.04476
Sonnet 5.5	$0.00010	$0.02238
Haiku 4.5	$0.00005	$0.01119

Security

Grade A, and why

ui-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 3d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/core.py, scripts/pick-style.cjs, scripts/search.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 359 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex compatibility note:

Invoke $skill-name: load the registered .agents/skills/<name>/SKILL.md and execute it with Codex tools; no separate Skill tool or Claude mode switch is needed. Author .claude/**; mirrors are generated.

Track steps before execution and keep progress/evidence current. Explicit skill requests execute their protocol. Use the native question tool for required questions.

Map foreign tool names to available host capabilities. A name mismatch needs no approval; an actually unavailable required capability stops with its step/evidence and a user question before adaptation.

Subagent authorization: when a skill is user-invoked or AI-detected and its protocol requires subagents, that skill activation authorizes use of the required spawn_agent subagent(s) for that task.

Preserve protocol order unless the user approves a deviation. Workflows use $start-workflow: gates stay fixed; other steps may flex with logged reasons and evidence. [BLOCKING] Mode routing — detect FIRST. An explicit mode wins; omitted --mode defaults to fast. --mode=review runs standalone or in a workflow: read references/mode-review.md in full and follow it instead of the design spine, search, lanes and design branches below.

Quick Summary

Review modes: For review/audit work, standalone defaults to --review-only (--report-only alias); --fix-loop enables review → validate → authorized fix → fresh re-review, default cap 3. --fix-loop --loop-owner=caller returns a read-only pass to the caller that owns fixes/re-review. Create triage, review, validation and re-review todo tasks first; apply the carried review-policy contract for LOW deferral and user-approved bounded extensions. Non-review modes and terminal findings validation keep their own dispatch.

Goal: Create (or describe) a UI design using design-intelligence databases and subagents, dispatched by --mode (input carrier) × --lane (design lane); --mode=review instead reviews existing UI for content fit, supported-size layout, styling conventions, layering, accessibility and async states.

Summary:

Route: parse --mode={fast|good|explore|describe|screenshot|video|review} and --lane={product|marketing}; default to fast × product. review replaces the design spine with references/mode-review.md (--lane does not apply).
Spine (BLOCKING order, every design mode — not review): Journey Report (UX-1) → design authority read — principles, design system, existing UI (UX-2) → design-intelligence search (candidates only) → ingest visual evidence when applicable → low-fi structure walked against the journeys (UX-7) → design with ui-ux-designer (DD-3 plan + UI-*/DD-*) → implement unless describe → validate by walking the journeys + traceability (UX-8) → report and seek approval.
Quality floor: apply project tokens/components plus UI-*/DD-*/CL-*; design states, interaction feedback, declared scales, measured contrast, touch targets, responsive reflow, and subject-grounded copy before the happy path.
Ownership: the design modes author the visual direction and implementation contract; --mode=review owns source findings and review evidence; the local index supplies candidates only.

Command routing: Use $ui-design with these values; the old commands do not resolve.

Old command	Current invocation
`/design-fast`, `/design-good`, `/design-describe`, `/design-screenshot`, `/design-video`	`$ui-design --mode=<same suffix>`
`/ui-review`	`$ui-design --mode=review [scope] [--report-only]` — read `references/mode-review.md` when selected
`frontend-design`, `interface-design`	`$ui-design --lane=marketing`, `$ui-design --lane=product` — read the selected `references/lane-{marketing,product}/lane-guide.md`

Mode dispatch: --mode={fast|good|explore|describe|screenshot|video|review} — default fast when omitted. Lane dispatch: --lane={product|marketing} — default product when omitted. Lane (the design tradition) is orthogonal to mode (the input carrier); any mode combines with any lane.

What ships with it

47 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

ui-design is a skill published in the GitHub repository duc01226/EasyPlatform (12 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 11,191 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-18.
