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.

A tool letting Claude push notifications to you stays off by default.

Feature flag
tengu_kairos_push_notifications On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The tool that lets Claude proactively notify you in the terminal and optionally on mobile is present but enabled only by tengu_kairos_push_notifications, whose compiled fallback is false, so it is not offered unless a server turns it on.

Details
  • Results are capped at 1000 characters and delivery is deferred.
  • Its result reports whether a push and a local notification were sent, and if not, a reason of config_off, user_present or no_transport.
Evidence

send a notification to the user via terminal and optionally mobile
