DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Guidance on when multiagent is worth it, and a corrected docs link

You'll notice
Useful2 Signal3
Agent SDK Docs

Multiagent docs gained a staged guide on when extra agents are actually worth it.

What

The multiagent docs gained a step-by-step section with Python examples: start with a roster of just {"type": "self"}, move reading-heavy sub-tasks to a cheaper worker model, and only then add dedicated specialists. The overview and skill entry point now point fan-out shaped work here.

Details
  • The URL fetched for live docs was wrong and is corrected from multi-agent.md to multiagent-orchestration.md.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
