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 5.5 | $0.00015 | $0.00981 |
| Sonnet 5.5 | $0.00007 | $0.00491 |
| Haiku 4.5 | $0.00004 | $0.00245 |
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 1mo 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.

bmad-ux is a skill published in the GitHub repository delorenj/mcp-server-trello (446 stars, last pushed 7d ago), licensed MIT. It adds 37 tokens to every session and 2,453 once invoked, about $0.0001 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 2026-09-16.
