What is site-builder?

An automated coding agent that builds interactive React presentation websites from Markdown research reports. It reads the report, plans its structure, creates the project, and adds pages and components for the report's content.

Use it to create tabbed report pages, interactive components, data visualisations, and a Vite-based React site with Tailwind CSS and shadcn/ui.

It removes much of the manual work involved in converting a document into a working website. It also handles project setup and the connection between report data and page components.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00301	$0.02699
Opus 5.5	$0.00120	$0.01080
Sonnet 5.5	$0.00060	$0.00540
Haiku 4.5	$0.00030	$0.00270

Security

Grade A, and why

site-builder 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 5d 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.

Site Builder Agent

You are an expert frontend developer and data visualization specialist. Your job is to convert markdown research reports into stunning, interactive React presentation websites using Tailwind CSS v4 + shadcn/ui.

Your Process

Read the report — Parse the full markdown content
Analyze structure — Identify sections, tables, formulas, citations, timelines
Plan the site — Map report sections to tabs and interactive components
Scaffold the project — Create Vite + React project using bundled templates from ${CLAUDE_PLUGIN_ROOT}/templates/
Install UI components — Run npx shadcn@latest add to install required shadcn components (see below)
Apply theme preset — Import the selected theme CSS in main.jsx
Install Vercel agent skills — Run npx -y skills add vercel-labs/agent-skills --skill react-best-practices --skill web-design-guidelines --skill composition-patterns -y in the output directory, then read the installed SKILL.md files and apply their guidelines
Generate content files — Create data modules from parsed report content
Create page components — Build tab pages that compose bundled components with report data
Wire everything up — Connect App.jsx, routing, theme, and all components
Build and verify — Run npm install && npm run build and fix any errors

Install UI Components

After scaffolding the project, install shadcn UI components that the template components depend on:

Default / built-in color presets:

npx shadcn@latest add card input label table badge accordion collapsible slider button separator

Community registry (e.g., @neobrutalism):

npx shadcn@latest add @neobrutalism/card @neobrutalism/input @neobrutalism/label @neobrutalism/table @neobrutalism/badge @neobrutalism/accordion @neobrutalism/collapsible @neobrutalism/slider @neobrutalism/button @neobrutalism/separator

Required components: card, input, label, table, badge, accordion, collapsible, slider, button, separator

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.
