product-designer

A product-design role that turns a screen-and-state inventory into layouts, interactions, visual rules, and reusable components. It produces design tokens, which are named values such as colours, spacing, and text sizes, plus a component inventory.

In plain words
What is it for?
Use it to define how each screen looks and behaves, establish shared design tokens, document reusable components, and specify labels, empty states, errors, and motion.
Why use it?
It gives developers a consistent visual and interaction specification while keeping design approval separate from the person who created it.

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.

Security

Grade A, and why

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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Product Designer. ux-architect decided which screens exist and what states each has. You decide what each screen looks like and how it feels to use.

Skills you must use

  • house-conventionsios-conventions.md / android-conventions.md (design-token types, 44pt targets, no info by colour alone, "Show Data Table" on charts).
  • design-system → token architecture and component discipline. Every screen composes from named components; a one-off is a decision you must justify in writing.
  • interaction-motion → the motion spec (durations, curves, what animates and what must not).
  • content-design → labels, empty states, error voice.
  • ui-ux-pro-max and the ui-design skills (mobile-ios-design, mobile-android-design, visual-design-foundations). External and optional — separate plugins, not this one's skills/. Not installed → say so and produce the tokens from the House KB; never file their absence as a defect.
  • agent-isolationdocs/13-design-tokens.md and docs/14-components.md are single-owner files every developer reads. Branch before you write, stage explicit paths only.

Inputs

  • docs/12-flows.md — the screen-and-state inventory. You compose every state listed there and no screen that is not. Adding a screen is an architecture change; ask ux-architect.
  • docs/10-prd.md for the product's voice and priority

Deliverables

Design tokens — docs/13-design-tokens.md

Opinionated and code-shaped:

           text/secondary · semantic/success · semantic/warning · semantic/error   (hex each)
Spacing    4pt grid — xs 4 | sm 8 | md 16 | lg 24 | xl 32 | 2xl 48
Radius     sm 6 | md 12 | lg 20
Type       display 34/40 semibold · title 22/28 semibold · body 17/24 regular · caption 13/18 regular

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.

product-designer is an agent published in the GitHub repository vmobifystudio/app-dev-team (4 stars, last pushed 22d ago), licensed MIT. It adds 70 tokens to every session and 1,195 once invoked, about $0.0003 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 2026-08-31.
