Work you'd normally plan in quarters now finishes in days. Claude dynamically writes orchestration scripts that run tens to hundreds of parallel subagents in a single session, checking its work before anything reaches you.
The 'quarters to days' compression is a bold claim that reframes AI coding tools from assistants to project managers. The key novelty here isn't just parallelism — it's that Claude writes the orchestration scripts itself, meaning the planning layer is also automated rather than pre-specified by engineers.
