Claude Code uses parallel sub-agents to speed up news crawls

A news crawling pipeline has been optimized by splitting its tasks across multiple parallel sub-agents, significantly reducing processing time. Previously, fetching 51 sources sequentially within a single agent turn led to exceeding Claude Code's background task wait ceiling. The new approach divides sources into smaller batches for parallel execution, with each sub-agent returning structured facts rather than full text, thereby keeping context windows manageable and cutting wall-clock time by approximately two-thirds.

    <p>A daily pipeline that crawls 51 release feeds and blogs one at a time takes long enough to risk hitting Claude Code's background-task wait ceiling. Splitting the same crawl across multiple parallel subagents, each returning structured facts instead of raw feed text, cuts wall-…
