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.

Cloud Sessions

You could get a startup notice when a cloud session could not be bound to your machine.

A "Not bound to this machine (local tools off)" notification exists behind the same off-by-default cloud flag.

Feature flag
tengu_violin_wood 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 v2.1.227: not a boolean we can read

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 v2.1.227. It isn't a statement about your account. What a flag value here can and cannot tell you

What

If a cloud session starts and the server returns no device id, the session now queues a plain-language notification instead of staying silent. The text is the fixed prefix Not bound to this machine (local tools off): plus a reason. It only appears on the cloud-session path and only when tengu_violin_wood is on.

Details
  • Reasons include "this account has reached its device limit", "no stored claude.ai login on this machine (run /login)", "the server refused it (server-side bind flag likely off)", and "the device feature flag was off or unreadable at create time".
Evidence

the device feature flag was off or unreadable at create time

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