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.

Built-in autonomous agent can run 500 turns

You'll notice
Useful3 Signal2
Agents

The built-in autonomous agent can now keep working for 500 turns instead of stopping at 200.

What

The turn budget for the built-in agent used for autonomous research, implementation and verification work rose from 200 to 500, so long agent runs stop far later. Unconditional.

Evidence

maxTurns: 500

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