tengu_left_arrow_editing_guard
A Claude Code feature flag, read out of the shipped bundle. It was in the build from v2.1.218 and was gone by v2.1.242.
What it is
In vim normal mode, pressing left arrow on an empty prompt now works as expected.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.219.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |
| 2.1.242 – 2.1.243 2 releases | not in the build | — | — |
| 2.1.218 – 2.1.241 23 releases | in the build | — | bool:true |
A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

Two arms, because they disagree: this account is the one account this site reads and anonymous is a baseline with no identity attached. A reading says nothing about your account, and off cannot rule out a rollout both readings sit outside of. What these readings can and cannot show.

None of Anthropic's documentation pages this site has a copy of carries this name.
Names beside it
Every feature flag in the inventory starting tengu_left_arrow, up to twelve of them.
Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the feature flag does. All feature flags.
