par parallel-web

Extract content from multiple URLs in parallel, token-efficiently. Handles webpages, articles, PDFs, and JavaScript-heavy sites with a single command Runs in a forked context to minimize token overhead compared to built-in WebFetch Supports batch extraction of multiple URLs with optional focus objectives Requires parallel-cli installation and authentication; outputs extracted content as markdown to a local file for follow-up queries

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.

Setup

If parallel-cli is not found, install and authenticate:

/parallel:parallel-cli-setup

If parallel-cli extract returns 403, tell the user balance is likely required. Offer to run parallel-cli balance get, and if needed ask for explicit confirmation before running parallel-cli balance add <amount_cents>. Then retry the original extract command.
