What

The Ultraplan feature — which launches a planning session in Claude Code on the web — now has a fully functional interactive UI in the CLI.

Status

Feature-flagged via tengu_ultraplan_config (must have enabled: true)

Details
  • Typing "ultraplan" in a prompt triggers keyword detection and launches the /ultraplan flow
  • "Run ultraplan in the cloud?" dialog with time estimates and option to disable Remote Control
  • Plan approval UI with three choices: "Implement here" (inject into current conversation), "Start new session" (clear and start fresh with the plan), or "Cancel" (save plan to file)
  • Scrollable plan preview with ctrl+u/ctrl+d to scroll
  • If Remote Control is active, launching ultraplan disables it with a warning
  • Rejected plans are saved to {session}-ultraplan.md
Evidence

Ultraplan config and UI (gated by tengu_ultraplan_config, search for "Run ultraplan in the cloud?" and "Ultraplan approved")

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

Feature flag
tengu_ultraplan_config Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.91: no gate table built for this version

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.91. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns {"enabled":false} for tengu_ultraplan_config, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
