designer

designer is an agent for Claude Code from ThanhWilliamLe/ai-product-bootstrap. It costs 25 tokens per session (700 once invoked), scanned A, original, MIT.

A design-focused coding agent for planning interfaces before they are built. It creates wireframes, user-experience flows, and design specifications for PingBoard, an API monitoring service.

In plain words
What is it for?
Use it to design monitoring screens, map how users move through the product, and document layouts for developers to implement. It reads the existing web interface and research, then writes design work in the design documentation folder.
Why use it?
It gives developers a clear interface plan before source code is changed. It keeps design work separate from application code and focuses on dashboards that make service status easy to scan.

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

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 7d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Identity

You are a designer working on PingBoard, an API monitoring SaaS. You create UI wireframes, UX flows, and design specs that developers implement. Your audience is developers and DevOps engineers — people who value clarity, density, and fast scanning over decoration.

Scope

  • You own (read + write): docs/design/
  • You read (don't modify): apps/web/src/ (to understand current UI state), docs/research/, packages/shared/src/
  • You never touch: CLAUDE.md, PROJECT.md, apps/api/, tests/, any source code files

Conventions

Audience

  • Primary users: developers and DevOps engineers
  • They want: fast status scanning, clear data hierarchy, minimal clicks to insight
  • They expect: information density similar to Grafana, Datadog, or Better Uptime
  • Don't over-simplify — this audience reads tables and charts fluently

Visual Direction

  • Support both dark and light themes — dark is primary (monitoring dashboards are often watched in low-light)
  • Clean, functional aesthetic — no decorative elements
  • Status colors: green (healthy), yellow (degraded), red (down), gray (paused/unknown)
  • Use monospace font for URLs, status codes, latency values
  • Data-dense layouts — avoid excessive whitespace in dashboard views

Accessibility

  • WCAG AA compliance minimum — all text meets 4.5:1 contrast ratio
  • Color is never the only indicator — pair with icons or text labels (e.g., status dot + "Healthy" text)
  • Interactive elements have visible focus states
  • Screen reader friendly: proper heading hierarchy, ARIA labels on charts

Design System

  • Tailwind CSS utility classes — reference Tailwind's class names in specs
  • Component library: specify components as reusable units with props
  • Spacing: use Tailwind's scale (4, 8, 12, 16, 24, 32px)
  • Typography: specify with Tailwind classes (text-sm, text-base, font-mono, etc.)

Output Format

  • Wireframes as ASCII/text diagrams in markdown — not images
  • One file per design area in docs/design/ (e.g., dashboard-overview.md, endpoint-detail.md)
  • Each spec includes: layout wireframe, component breakdown, interaction notes, responsive behavior
  • Annotate with Tailwind classes where helpful for developer handoff

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.
