parallel-web-extract

A URL content extractor that fetches and returns information from webpages, articles, PDFs, and sites that rely on JavaScript to display content.

In plain words
What is it for?
Use it to retrieve the contents of a supplied URL, focus extraction on particular topics or keywords, or obtain fuller text from long pages and documents.
Why use it?
It turns content hidden behind different page formats or scripts into information a coding agent can work with, reducing the need for manual copying.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

parallel-web-extract 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

URL Extraction

Extract content from: $ARGUMENTS

Command

Choose a short, descriptive filename based on the URL or content (e.g., vespa-docs, react-hooks-api). Use lowercase with hyphens, no spaces. Substitute it into the command inline$FILENAME is a placeholder, not a shell variable.

parallel-cli extract "$ARGUMENTS" --json -o "/tmp/$FILENAME.json"

Concrete example:

parallel-cli extract "https://docs.parallel.ai" --json -o "/tmp/parallel-docs.json"

Note: -o always saves JSON. The extension must be .json.

Options if needed:

  • --objective "focus area" to focus extraction on a specific goal (also silences the "neither objective nor search_queries" warning that V1 emits when neither is set)
  • -q "keyword" (repeatable) to prioritize keywords in excerpts
  • --full-content to include the complete page body (for long articles, PDFs, or when excerpts may not capture what you need)
  • --full-content-max-chars N to cap full-content size per result
  • --no-excerpts to strip excerpts when you only want full content

Handling failed extractions

If the response has an errors field, an empty results array, or a 404/timeout for the URL, do NOT fabricate content. Tell the user the extraction failed, surface the upstream status, and suggest:

  • Verifying the URL (the page may have moved)
  • Retrying with --full-content if excerpts came back empty but the page exists
  • Using parallel-cli search to locate the current URL if the page was renamed

Response format

Return content as:

Page Title

Then the extracted content verbatim, with these rules:

  • Keep content verbatim - do not paraphrase or summarize
  • Parse lists exhaustively - extract EVERY numbered/bulleted item
  • Strip only obvious noise: nav menus, footers, ads
  • Preserve all facts, names, numbers, dates, quotes

After the response, mention the output file path (/tmp/$FILENAME.json) so the user knows it's available for follow-up questions.

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.

parallel-web-extract is a skill published in the GitHub repository parallel-web/parallel-agent-skills (73 stars, last pushed 19d ago), licensed MIT. It adds 42 tokens to every session and 672 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
