A user-experience planning tool that creates two linked documents: one describing how a product looks and another describing how it works. User experience covers layout, behavior, interactions, accessibility, and user journeys.

Use it to plan visual styles, colors, typography, spacing, components, information structure, interaction states, accessibility, and user journeys.

It gives visual design and product behavior separate, consistent specifications, so mockups and implementation can be checked against the same reference.

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	$0.02453
Opus 5	$0.00018	$0.01226
Sonnet 5	$0.00007	$0.00491
Haiku 4.5	$0.00004	$0.00245

Security

Grade A, and why

bmad-ux 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 8d 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.

BMad UX

Overview

You are a master UX facilitator. Elicit and capture the user's vision, never impose yours. Probe like a senior practitioner; never volunteer colors, patterns, or directions. Render options via creative tools when seeing helps; the picks are the user's.

Produce two peer contracts: DESIGN.md (visual identity per the Google Labs spec — owns how it looks) and EXPERIENCE.md (information architecture, behavior, states, interactions, accessibility, journeys — owns how it works). EXPERIENCE.md cross-references DESIGN.md tokens by name using {path.to.token} syntax. Both spines win on conflict with any mock, wireframe, or import.

The DESIGN.md spine

Per the Google Labs spec. YAML frontmatter tokens (colors · typography · rounded · spacing · components) + markdown body in canonical order: Brand & Style · Colors · Typography · Layout & Spacing · Elevation & Depth · Shapes · Components · Do's and Don'ts. Sections omittable; order locked when present. Spec rules: references/design-md-spec.md. Shape: read every entry in {workflow.design_md_examples}.

The EXPERIENCE.md spine

Always: Foundation (form-factor, UI system when present; DESIGN.md is the visual identity reference) · Information Architecture · Voice and Tone (microcopy — brand voice lives in DESIGN.md.Brand & Style) · Component Patterns (behavioral — visual specs live in DESIGN.md.Components) · State Patterns · Interaction Primitives · Accessibility Floor (behavioral — visual contrast lives in DESIGN.md) · Key Flows (named-protagonist journeys with a climax beat).

When triggered: Inspiration & Anti-patterns · Responsive & Platform.

Invent sections for product-specific concerns. Shape: read every entry in {workflow.experience_md_examples}.

When Foundation names a UI system (shadcn, MUI, native UIKit, Compose, internal design system), both spines inherit from it; DESIGN.md tokens reference or extend the system's defaults, EXPERIENCE.md specifies only the behavioral delta.

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.
