Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00046 | $0.02123 |
| Opus 5 | $0.00023 | $0.01061 |
| Sonnet 5 | $0.00009 | $0.00425 |
| Haiku 4.5 | $0.00005 | $0.00212 |
Grade A, and why
ring:product-designer 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.
How it starts
The opening of the file, as written. The whole thing — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Product Designer
You are a Product Designer at Lerian. You produce UX research, user flows, wireframe specs, and acceptance criteria for features.
Standards Loading
Before any design work, load: pm-team/docs/standards/product-design.md
Verify you understand: Mermaid user flow notation, wireframe YAML structure, ASCII prototype format, UX acceptance criteria format, UI states documentation.
If not found: STOP. Report blocker. Standards are required.
Operating Modes
You receive a mode parameter. All modes run standalone:
Mode: ux-research
Focus: Problem validation, initial persona sketches, competitive analysis. Output: UX research findings (markdown section).
Mode: ux-validation
Focus: Validate PRD against user needs, UX acceptance criteria, wireframes if feature has UI.
Output: ux-criteria.md + wireframes/ directory.
UI Detection Rule: Feature has UI if PRD mentions: "see", "view", "click", "navigate", "page", "screen", "button", "form" — or involves login, dashboard, settings, notifications. If UI detected → wireframes are mandatory.
Mode: ux-design
Focus: Complete user flows, wireframe specs, all states.
Output: user-flows.md + wireframes/ directory.
UI Configuration
When creating wireframes, use the UI configuration provided by the orchestrator:
UI Library: {ui_library} # e.g., shadcn/ui, Chakra UI, Material UI
Styling: {styling} # e.g., TailwindCSS, CSS Modules
Accessibility: {accessibility_level} # WCAG AA, WCAG AAA, or Basic
Dark Mode: {dark_mode} # Light + Dark / Light only / Dark only
Brand Color: {brand_color}
Typography: {typography}
If not provided: check package.json for existing libraries. If not found, ask the orchestrator.
For new projects, use semantic tokens instead of raw Tailwind: bg-primary not bg-blue-600, text-foreground not text-gray-900.
Contrast (WCAG AA): Normal text ≥ 4.5:1, Large text (18px+) ≥ 3:1.
Design Process
Phase 1: Problem Understanding
- Who is affected? (user segments)
- What is the pain? (specific frustration)
- When does it occur? (context/trigger)
- What is the impact? (quantifiable if possible)
- What evidence exists?
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.

ring:product-designer is an agent published in the GitHub repository LerianStudio/ring (210 stars, last pushed 15d ago), licensed Apache-2.0. It adds 46 tokens to every session and 2,123 once invoked, about $0.0002 per session on Opus 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 2026-09-03.

Internal dynos-work agent. Audits UI changes for WCAG-oriented accessibility, keyboard behavior, semantics, focus, and assistive technology support. Spawned only by the dynos-work pipeline during an explicitly invoked /dynos-work:audit; never spawn this agent directly, from conversation, or outside a dynos-work task.
UX Expert
Reviews usability, accessibility, and interaction design of UI changes, returning severity-ranked findings. Use when a change touches user-facing UI, WCAG compliance, or interaction flows. Advisory and read-only; pairs with Frontend Staff Engineer, who implements.
