tengu_playful_lobster
A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.235, including the newest one read.
What it is
Claude Code now quietly notes when a file you read has more than one name, without changing what's allowed.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.235.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |
| 2.1.235 – 2.1.243 9 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.
Gate readings
| Release | Resolved | This account | Anonymous | Compiled default |
|---|---|---|---|---|
| v2.1.235 | Not enough to say | no value returned | no value returned | off |
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.

Every feature flag in the inventory starting tengu_playful, 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.
