data-acquisition-browser

data-acquisition-browser is a skill for Claude Code, Codex from Pranjay-kumar/universal-data-acquisition-pipeline-skill. It costs 72 tokens per session (1,037 once invoked), scanned A, original, MIT.

A browser-based data-collection skill for public or authorized websites. It can inspect pages, capture browser network activity, find data routes, and use the page's visible content when structured data is unavailable.

In plain words
What is it for?
Use it to inspect rendered pages, discover data requests, capture small DOM or JSON samples, take screenshots, and work with user-owned browser storage.
Why use it?
Some websites only reveal useful data after a browser loads the page or creates temporary session information. This helps investigate those pages while keeping access limited to public or authorized use.

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

data-acquisition-browser 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 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/patchright_cookie_endpoint_probe.mjs, scripts/patchright_page_dom_probe.mjs, scripts/playwright_probe.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Data Acquisition Browser

Act as the browser acquisition specialist. Use Patchright for warm-session capture when a normal browser must mint cookies or storage state before API endpoints are visible. Use Playwright for ordinary rendered-DOM fallback when structured HTTP probes are insufficient and no warm browser context is needed.

When the user asks for page loads only or "no API", use Patchright as a renderer and extract DOM/JSON-LD/meta/visible rows only. Do not harvest, replay, or recommend structured endpoints in that mode.

Shared Core

Read from ../data-acquisition-core/references/:

  • source-access.md
  • playwright-rendered-dom.md
  • probing.md
  • compliance-boundaries.md
  • output-contracts.md

Helpers

Use scripts/patchright_cookie_endpoint_probe.mjs for warm-session cookie/storage generation and endpoint discovery. Use scripts/patchright_page_dom_probe.mjs for Patchright page-load-only DOM extraction. Use scripts/playwright_probe.mjs only for ordinary public rendered-DOM fallback.

From the repo root:

npm install
npx patchright install chrome
npm run probe:patchright -- "https://example.com/public-category" "outputs/example-patchright-endpoints.json"

The Patchright helper opens a persistent Chrome context, lets the page create ordinary browser-issued cookies/storage state, records JSON/API/XHR-looking requests and responses, saves local storage state under auth/, and writes a redacted endpoint report.

Page-load-only mode:

$env:PATCHRIGHT_HEADLESS = "0"
npm run probe:patchright-page -- "https://example.com/category" "outputs/example-page-dom.json"

This mode records rendered page metadata, JSON-LD, canonical URL, visible text, candidate links, product/listing-like DOM nodes, and a screenshot. It sets api_endpoint_discovery: false and replay_attempted: false.

Useful options:

$env:PATCHRIGHT_STORAGE_STATE = "auth\target-storage-state.json"
$env:PATCHRIGHT_USER_DATA_DIR = "auth\target-profile"
$env:PATCHRIGHT_HEADLESS = "0"
npm run probe:patchright -- "https://example.com/category" "outputs/target-endpoints.json"

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
