What it does

Data Extractor is an agent skill from hanzili/hanzi-browse. Extract structured data from websites into CSV or JSON. Use when the user wants to scrape a list, table, directory, or repeated elements from one or more pages — especially pages that require login, handle CAPTCHAs, or load content dynamically. Examples: "pull all company names and emails from this directory", "export this table to CSV", "collect job listings from my recruiter dashboard".

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering Web scraping, CSV and tabular files and Schema markup. It works with Chrome Extensions and Model Context Protocol. The repository describes itself as: let any ai agent use the local browser.

When your agent uses it

  • The user wants to scrape a list
  • Repeated elements from one
  • More pages — especially pages that require login
  • Handle CAPTCHAs

Example prompts

  • “pull all company names and emails from this directory”
  • “export this table to CSV”
  • “collect job listings from my recruiter dashboard”
  • “/data-extractor”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Understand the Target
  2. Navigate and Collect
  3. Output the Data

What it can do on your machine

Read from SKILL.md and the folder at commit ce6e10d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • alumni.university.edu

    Also links to:

    • chromewebstore.google.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Data Extractor loads about 2.2k tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 875 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~102
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 875 words (~2,185 tokens).

“You extract structured data from websites into CSV or JSON. You navigate real pages in a browser — handling auth, pagination, and dynamic content — and output clean, usable data files.”
