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.

Ultraplan approval dialogs guard against stray input

You'll notice
Useful3 Signal2
Plan Mode

Ultraplan approval dialogs cancel themselves if a stray keystroke arrives just before they appear.

What

The dialogs that launch an ultraplan cloud session and then ask what to do with the finished plan were rewritten, and they now cancel themselves if the terminal received input it treated as refused just before the prompt appeared. This stops a selection being accepted by a keystroke you meant for something else.

Details
  • Two dialog kinds, ultraplan_choice and ultraplan_launch, each carrying the prompt text and a flag for whether the dialog arrived over the relay from the browser.
  • The guard tracks recently refused input and auto-cancels rather than accepting a choice.
  • No separate feature flag: this is on wherever the ultraplan path runs.
Evidence

kind: "ultraplan_choice"

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