The grace-window nudge can now ask Claude to checkpoint and list remaining work, but stays off.

A next-steps grace-window mode exists alongside wrap-up, with off as the fallback.

What

When you hit a usage limit and a grace window opens, the wrap-up nudge is no longer a single fixed message. It is now a three-way mode set by tengu_lantern_wick_mode: off, wrap-up, or the new next-steps, which asks the model to checkpoint and list up to 3 bullets of remaining work. The fallback is off, and any unrecognised value is treated as off, so nothing appears unless the server turns it on.

Details
  • The message opens "[Usage limit reached — grace window active. Checkpoint now: finish the ...".
  • The telemetry event now records which variant fired, including next_steps.
