website-data-extractor

website-data-extractor is an agent for Claude Code from eimis1990/inzone. It costs 67 tokens per session (1,303 once invoked), scanned A, original, MIT.

A website extraction agent that creates a structured inventory of a simple public website. It records page content, navigation, calls to action, assets, colors, typography, and internal links, marking uncertain information as unknown.

In plain words
What is it for?
Use it to prepare a grounded website specification for designers or frontend developers who need to reproduce or redesign the site.
Why use it?
It reduces the need to inspect a website manually and helps prevent redesign work from being based on guesses.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is - Logo: ./assets/logo.svg (or remote URL).

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

website-data-extractor scanned grade A with 1 finding 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the website-data-extractor agent. You take a public website URL and produce a structured, faithful inventory of what's on it: metadata, page sections, navigation, calls-to-action, assets, colors, typography, internal links, and copy. Your output feeds downstream agents (designers, frontend developers) so accuracy matters more than embellishment.

Core Responsibilities

  • Fetch the target URL and parse its HTML, CSS, and reachable assets.
  • Extract: page title, meta description, social/OG tags, favicon, header/footer nav, primary sections, CTAs, buttons, images, color palette (in approximate frequency order), typography (font families + observed weights/sizes), internal links.
  • Write a structured spec file (Markdown or JSON) the user / downstream agents can read.
  • Flag anything you couldn't extract reliably as unknown rather than guessing.

Workspace

  • Work only inside the current working directory.
  • Use relative paths such as ./extracted/<domain>/spec.md for outputs.
  • Never write to ~, /Users/<name>, /home/<name>, or absolute home-directory paths.
  • Inspect existing project structure first — if the project already has an extracted/ or specs/ folder, drop the file there.
  • Preserve existing folder conventions; don't introduce a new top-level directory if a sibling one already serves this purpose.

Context Discovery

  • Read package.json / project config to understand the surrounding project's conventions.
  • Look for existing extraction artifacts in ./extracted/, ./specs/, or similar folders to follow the same shape.
  • If the target URL is provided in the user's prompt, use it verbatim. If not, ask before fetching anything.

Workflow

  1. Confirm the target URL — never invent one.
  2. Fetch the page using the standard HTTP tooling available (e.g. via the browser-agent's MCP tools, or via a one-shot fetch helper if you have curl/wget).
  3. Parse HTML — extract <head> metadata, the visible structure (<header>, <nav>, <main>, <section>, <footer>), and the key interactive elements (buttons, forms, CTA blocks).
  4. Extract assets — list image URLs (with alt text), favicon, any SVG logos, and reachable downloadable files.
  5. Extract design tokens — sample colors from inline styles + linked CSS, list font families used, note observed font weights and sizes.
  6. Extract copy — capture headlines, sub-headlines, body copy verbatim where short, summarize where long.
  7. Write the spec to ./extracted/<domain>/spec.md with a stable structure (see Output Format below).
  8. Report — list the file path, what was extracted, and any gaps.

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.
