Extract explicitly selected URLs into a saved JSON result through the Parallel CLI.
Editorial review checked 2026-10-31 against this instruction snapshot. Supporting scripts and runtime behavior remain outside this editorial review.
The entry reserves the CLI path for explicit use, CLI-only controls or missing MCP fetch capability. It describes bounded multi-URL requests, focused or full-content output and per-URL failures. A saved result is the authoritative artifact because console previews can truncate, and successful and failed URLs can coexist.
Researchers and developers who need a reproducible extraction file rather than an informal page preview.
CLI installation, authentication and service eligibility are separate prerequisites. Output paths can be overwritten and full-content responses can still be capped. The instruction requests preservation of retrieved text, but publication or redistribution must also respect applicable source rights and the host environment rules.
Requires parallel-cli and internet access.
Extraction sends the requested URLs and optional objective or query terms to Parallel. Account, policy or billing failures need their actual diagnosis; no account was connected or service balance changed by the catalog.
Instruction-level disclosure at the checked snapshot; not an independent audit of the service or its current terms.

Inspect the pinned source snapshot and its supporting files first. The command selects this skill through the open-source skills CLI. Node.js and agent-specific setup may be required. Installation can download code. Catalog ingestion never executes skill instructions or install scripts.

After source review, use npx skills check and npx skills update to inspect and apply upstream updates. Re-check changed instructions before running them.

Scores summarize observable discovery signals. Popularity and repository activity apply to the whole repository. Unknown runtime safety earns no certification.
Confirm the requested URLs and inspect the destination file before constructing separate quoted arguments. Choose the content scope, run only an authorized service request and inspect status, per-URL errors and the actual saved file before presenting any result.
Check successful content against its source URL and label excerpts, caps and partial failures accurately. Ensure a failed request did not leave a stale file that is mistaken for new output. Distinguish data retrieval from permission to reproduce an entire third-party page.
