DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs.

Past 95% of five-hour usage Claude could be told to checkpoint and list remaining work, off here.

A wrap-up checkpoint message at 95% usage is behind a gate that falls back to off.

Feature flag

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 v2.1.229. It isn't a statement about your account. What a flag value here can and cannot tell you

What

When five-hour usage crosses 95% and the account is not in overage, Claude gets a message telling it to checkpoint: finish the current step, list up to three bullets of the most impactful remaining work, and start no subagents or long-running work. A usage_limit_near_wrapup event is recorded. The whole path is behind the tengu_vellum_anchor gate, which falls back to off, so with no remote config value nothing is injected.

Details
  • The exact injected text is "[Usage limit approaching. Checkpoint now: finish the current step, then list up to 3 short bullets of the most impactful remaining work. Don't start subagents or long-running work.]".
  • None of this machinery existed in 2.1.228.
