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.

Self-scheduling loop state survives a background handoff

Not switched on
Useful2 Signal4
Sessions not in their notes

Checkpoints now record self-scheduling wake counts and open artifact watches, though the loop itself is off.

Loop state survives handoff, but the loop is behind tengu_kairos_loop_dynamic, which falls back to false.

Feature flag
tengu_kairos_loop_dynamic 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.

tengu_kairos_loop_dynamic
What

Session checkpoints now record how many times a self-scheduling loop has woken and what live Artifact watches were open, and each scheduled wake-up records when it is due, why, and whether it holds a keepalive budget. The loop feature itself is behind tengu_kairos_loop_dynamic, whose in-source fallback is false, so it is off absent a server value.

Details
  • The wake count is stored as a non-negative integer, so a loop's wake budget carries over instead of resetting when the session is handed off to the background.
