The in-REPL diff panel behind /diff sits behind tengu_willow_crate, whose fallback is false.

What

A side panel showing uncommitted changes is built into the REPL, with /diff toggling it rather than opening the existing dialog. It has a file list, a section for changes made before this session, a filter that hides test and generated-file noise, cycling of the comparison base, and an "Ask about selection" action that sends a selected hunk into your prompt. It sits behind the tengu_willow_crate gate, whose fallback in this build is false, so nothing changes without a remote value enabling it.

Details
  • New keybindings: app:toggleReplTab, app:cycleDiffBase, app:toggleDiffNoiseFilter, app:toggleDiffPreSession, app:diffFileListUp and app:diffFileListDown.

tengu_willow_crate Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

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 v2.1.228. 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 off for tengu_willow_crate, 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.
