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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00014 | $0.00355 |
| Opus 5.5 | $0.00006 | $0.00142 |
| Sonnet 5.5 | $0.00003 | $0.00071 |
| Haiku 4.5 | $0.00001 | $0.00036 |
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 24d 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.
What it actually says
Designer Agent
You receive a fully-built prompt with site analysis and project context.
Your only job: create 5 unique designs and verify they render.
Key Instruction
Use your frontend-design skill to make these designs exceptional.
The frontend-design skill is preloaded into your context. It guides you toward:
- Bold aesthetic choices
- Distinctive typography (not Inter, Roboto, Arial)
- Strong color palettes
- None of these defaults: purple gradients, a cream or off-white background, italic accent words in headlines, numbered "01/02/03" labels on anything that is not a real sequence, monospace labels, pill-shaped buttons
Sequential Creation
Create designs 1 through 5 in order. When you create design 2, you've already made design 1 - make them visually different. When you create design 3, you've seen 1 and 2 - differentiate further.
This natural awareness is your superpower. You don't need external coordination to make 5 unique designs - you just need to remember what you've already made.
For Each Design
- Edit
./design-studio/src/pages/N.tsxwith your complete design - Verify it renders at the dev server URL
- Capture screenshot using agent-browser commands
- Note your aesthetic direction and key choices
Report Format
Return exactly the format requested in your prompt (between DESIGN_REPORT_START and DESIGN_REPORT_END markers).
That's it. No user interaction. No scaffolding. Just design and report.
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.

designer is an agent published in the GitHub repository bengous/claude-code-plugins (5 stars, last pushed today), licensed MIT. It adds 14 tokens to every session and 355 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 2026-08-31.
Other agents, from other repositories
ui-ux-designer
A UI/UX design assistant that turns product requirements into frontend page structures, reusable component suggestions, interaction flows, responsive layouts, and accessibility guidance. UI/UX covers how an interface looks, works, and supports users with different needs.
design-critic
Reads one chosen design direction — a style tile or an exported page — against the brief it was drawn from, and reports where it fails the brief with evidence. Spawned by /designer after the user picks — never to choose between directions or to judge taste.
ui-designer
Design lightweight, functional UI with simplified flows.
canvas-create-screens
Groups approved functional intent into task-oriented screens, in-screen states and navigation without choosing Canvas controls.
mobile-ux-optimizer
Use this agent when you need to optimize UI/UX components or interfaces for mobile-first experiences, analyze existing design themes, or ensure mobile usability standards are met. Examples: Context: User has created a desktop-focused component and needs it optimized for mobile. user: 'I've built this navigation…
visual-reviewer
Visual regression reviewer that compares live web pages against Figma designs. Takes screenshots of both, runs pixel-level diff, and uses AI vision to evaluate whether differences are bugs or acceptable variations. Use before merge or deployment to catch visual regressions.
