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 | $0.00096 | $0.06754 |
| Opus 5 | $0.00048 | $0.03377 |
| Sonnet 5 | $0.00019 | $0.01351 |
| Haiku 4.5 | $0.00010 | $0.00675 |
Grade A, and why
clone-website 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 9d 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.
This is a copy
91% identical to clone-website — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 474 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Clone Website
You are about to reverse-engineer and rebuild $ARGUMENTS as pixel-perfect clones.
When multiple URLs are provided, process them independently and in parallel where possible, while keeping each site's extraction artifacts isolated in dedicated folders (for example, docs/research/<hostname>/).
This is not a two-phase process (inspect then build). You are a foreman walking the job site — as you inspect each section of the page, you write a detailed specification to a file, then hand that file to a specialist builder agent with everything they need. Extraction and construction happen in parallel, but extraction is meticulous and produces auditable artifacts.
Scope Defaults
The target is whatever page $ARGUMENTS resolves to. Clone exactly what's visible at that URL. Unless the user specifies otherwise, use these defaults:
- Fidelity level: Pixel-perfect — exact match in colors, spacing, typography, animations
- In scope: Visual layout and styling, component structure and interactions, responsive design, mock data for demo purposes
- Out of scope: Real backend / database, authentication, real-time features, SEO optimization, accessibility audit
- Customization: None — pure emulation
If the user provides additional instructions (specific fidelity level, customizations, extra context), honor those over the defaults.
Pre-Flight
- Browser automation is required. Check for available browser MCP tools (Chrome MCP, Playwright MCP, Browserbase MCP, Puppeteer MCP, etc.). Use whichever is available — if multiple exist, prefer Chrome MCP. If none are detected, ask the user which browser tool they have and how to connect it. This skill cannot work without browser automation.
- Parse
$ARGUMENTSas one or more URLs. Normalize and validate each URL; if any are invalid, ask the user to correct them before proceeding. For each valid URL, verify it is accessible via your browser MCP tool. - Verify the base project builds:
npm run build. The Next.js + shadcn/ui + Tailwind v4 scaffold should already be in place. If not, tell the user to set it up first. - Create the output directories if they don't exist:
docs/research/,docs/research/components/,docs/design-references/,scripts/. For multiple clones, also prepare per-site folders likedocs/research/<hostname>/anddocs/design-references/<hostname>/. - When working with multiple sites in one command, optionally confirm whether to run them in parallel (recommended, if resources allow) or sequentially to avoid overload.
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.
