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.

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.

This account: on · anonymous baseline: on · compiled default in v2.1.110: no gate table built for this version

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.

What

A tool that allows Claude to send notifications to the user's terminal and, when Remote Control is connected, push to their mobile device. Claude decides when to notify based on whether the user appears to be away and whether the event is actionable.

Status

Feature-flagged via tengu_kairos_push_notifications (default: false) and tengu_kairos_input_needed_push (default: false)

Details
  • Full implementation including tool definition, status rendering, mobile push via Remote Control API, and notification preference sync to /api/claude_code/notification/preferences
  • The tool includes sophisticated logic: it only sends when the user appears away, considers terminal focus state, and respects user configuration
  • User-facing status messages like "Terminal notification sent. Mobile push requested." and "Not sent because you're active in this terminal."
  • Configuration options: "Push when Claude decides" and "Push when actions required" appear in /config
  • Links to https://claude.com/download#mobile for mobile app setup
  • The tool prompt coaches the model: "err toward NOT sending. Not every event is worth a push; the ones that change what they'd do next are."
Evidence

PushNotification tool (gated by tengu_kairos_push_notifications, search for "PushNotification" and "Send a notification to the user via their terminal")

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