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 Notable not in their notes

A cloud session can hold its first reply until your settings arrive; two env vars shorten the wait.

What

A cloud session can hold the first turn until your forwarded settings have been applied or a timeout fires, so they affect that first reply instead of the next one. Two environment variables tune the wait, CLAUDE_CODE_HOME_SEED_HOLD_TIMEOUT_MS and CLAUDE_CODE_HOME_SEED_VERDICT_TIMEOUT_MS, and both are clamped against built-in caps, so they can only shorten it.

Details
  • The confirmation notice switches between " (in effect for this reply)" and " (from your next message)" depending on whether the hold succeeded.
  • Setting the hold timeout to zero or less skips the hold entirely.
  • Outcomes reported to telemetry: released, timeout, verdict_timeout, flag_timeout, interrupted, gate_off.
