parallel-web-extract
여러 URL에서 병렬로 콘텐츠를 추출하며, 토큰 효율적으로 처리합니다. 단일 명령어로 웹페이지, 기사, PDF, JavaScript 중심 사이트를 처리합니다. 포크된 컨텍스트에서 실행되어 내장 WebFetch보다 토큰 오버헤드를 최소화합니다. 선택적 초점 목표와 함께 여러 URL의 배치 추출을 지원합니다. parallel-cli 설치 및 인증이 필요하며, 추출된 콘텐츠를 마크다운 형식으로 로컬 파일에 출력하여 후속 질의에 활용할 수 있습니다.

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.
Pass each requested URL as a separate quoted positional argument, up to 20 per call. Do not collapse multiple URLs into one quoted $ARGUMENTS string or use eval to split them. Construct arguments directly from the requested URLs. For example:
parallel-cli extract "https://docs.parallel.ai/integrations/cli" "https://docs.parallel.ai/integrations/cursor-marketplace" --json -o "/tmp/parallel-docs.json"
-o saves JSON. Use a .json extension and inspect an existing path before use because Extract overwrites it. Read the saved file as authoritative; stdout may truncate and human-readable output previews only part of the content. Do not treat a stale file as a successful response after a failed call.
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-contentto include the complete page body (for long articles, PDFs, or when excerpts may not capture what you need)--full-content-max-chars Nto cap full-content size per result--no-excerptsto strip excerpts when you only want full content--session-id "<returned-session-id>"to group related Search/Extract calls. A session ID is not a Task interaction ID or run ID; never use it with research status/poll or--previous-interaction-id
Handling failed extractions
Inspect the exit status, API error, results, per-URL errors and any warnings. errors: [] is normal success. Nonempty errors can coexist with successful results: retain and present successful content, then name each failed URL and its returned reason. Empty results or missing content are not a successful extraction. Do not fabricate content. For affected URLs, suggest:
- Verifying the URL (the page may have moved)
- Requesting
--full-contentif excerpts are empty but the returned metadata supports that the page was fetched - Using
parallel-cli searchto locate the current URL if the page was renamed
Response format
Return content as:
Use returned full_content for full-page requests; excerpts alone are selected passages and must be labelled as such. Even full content may be capped by --full-content-max-chars or upstream limits; do not promise completeness when capped. Preserve retrieved content verbatim, with these rules:
- Keep content verbatim - do not paraphrase or summarize
- Preserve every numbered/bulleted item in the retrieved content; do not claim an excerpt contains the whole page
- 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.
For large content, keep the full verbatim text in the saved file and provide a brief labelled preview plus its path. Never silently truncate content while claiming it is the complete extraction.
Setup
If parallel-cli is not found, install and authenticate:
/parallel:parallel-cli-setup
If a documented command or option is missing, check the installed version and upgrade through its installation method: standalone parallel-cli update, pipx pipx upgrade parallel-web-tools, uv uv tool upgrade parallel-web-tools, Homebrew brew upgrade parallel-web/tap/parallel-cli, or npm npm update -g parallel-web-cli. Verify help in the same terminal before retrying.
For authentication errors, inspect parallel-cli auth --json and its authenticated boolean; exit zero alone does not prove authentication. A 403 can indicate permissions, policy or billing. Report the actual error; check balance only for a billing-specific failure and never add funds without explicit confirmation.
