Source Intelligence

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 & Limits

You could be told when you are near the 5-hour usage limit instead of Claude just wrapping up.

The approaching-limit notice is behind tengu_vellum_anchor, which falls back to false.

Feature flag
tengu_vellum_anchor Off in both readings

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.

This account: off · anonymous baseline: off · compiled default in v2.1.236: on

Read once, for one account on one subscription tier, against v2.1.236. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A user-facing message, "Approaching your 5-hour usage limit — Claude will wrap up the current step.", is shown before the existing wrap-up instruction is injected, so the behaviour is explained rather than silent. It is behind the tengu_vellum_anchor flag, which falls back to false, so it is off in this build unless remote config enables it.

Evidence

Approaching your 5-hour usage limit — Claude will wrap up the current step.

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