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.

Cap how big Claude's dynamic workflows get with a new workflowSizeGuideline setting.

workflowSizeGuideline/config
What

A settings key that gives Claude an advisory size hint for the dynamic workflows it writes, with four accepted values.

Details
  • Accepts "unrestricted", "small", "medium" or "large": small is under 5 agents, medium (the default) under 15, large under 50
  • A settings-file or managed value takes precedence over the "Dynamic workflow size" row in /config, and that row is hidden entirely while a settings file supplies the key
  • The /config row now also shows whether the current value is the default
  • The /config row appears only when the workflows feature is on
Usage
{"workflowSizeGuideline":"small"}
Evidence

Advisory size guideline for the dynamic workflows Claude writes

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