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.

 There are three additional built-in output styles:
 
-* **Proactive**: Claude executes immediately, makes reasonable assumptions instead of pausing for routine decisions, and prefers action over planning. This is stronger autonomous-execution guidance than [auto mode](/docs/en/permission-modes#eliminate-prompts-with-auto-mode) applies, and it works without changing your permission mode, so you still see permission prompts before tools run.
