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.

Usage-limit grace notice, compiled in but off

Not switched on
Useful3 Signal4
Terminal UI Notable not in their notes

A status bar notice about usage limits and covered extra usage is built but switched off.

The usage-limit grace notice runs only when tengu_lantern_sconce returns true, and the compiled value is false.

Feature flag
tengu_lantern_sconce 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 v2.1.247: on

Read once, for one account on one subscription tier, against v2.1.247. It isn't a statement about your account. What a flag value here can and cannot tell you

tengu_lantern_sconce
What

A new status bar item can show Usage limit reached with the time it resets, or Usage limit reached ยท a little extra on us, then your credits when extra usage is being covered for you. It runs only when the server flag tengu_lantern_sconce returns true; the value compiled into this build is false, so nothing appears unless a server says otherwise.

Details
  • The notice has three internal phases: finishing the current work, covered by extra usage, and waiting for the reset.
  • It emits a usage_limit_grace_notice event when shown.
  • A separate mock path can force the notice on for testing regardless of the flag.
Evidence

Usage limit reached \xB7 a little extra on us, then your credits

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