parallel-web-extract

A URL content extractor that fetches text from webpages, articles, PDFs, and JavaScript-heavy sites.

In plain words
What is it for?
Use it to retrieve web content for research, summaries, analysis, or other tasks that need information from a URL.
Why use it?
It avoids manually opening and copying content from different kinds of web pages. It can focus on a specific topic or keyword and save the extracted result as JSON.

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 yesterday.

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 — 65 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-cursor-plugin (3 stars, last pushed 3mo ago), licensed MIT. It adds 42 tokens to every session and 680 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 2026-08-31.
