Prompts are held back with a quiet_spell outcome after one goes unanswered

What

A permission prompt is the question Claude Code asks before it does something that needs your approval. A subagent is a helper agent that the main Claude starts to work on part of a task. Before, every permission request from a subagent raised its own prompt, and a prompt that timed out only noted that it had gone unanswered.

Now, when a prompt in the same turn has timed out with no answer, a later request from a subagent does not raise another prompt. It returns the outcome quiet_spell instead.

• The quiet period lasts as long as the prompt timeout.
• A timed-out prompt is recorded as unanswered (promptsUp.unanswered), and answering any prompt with allow or deny clears that record.
• The behavior is controlled by tengu_hushed_plover. When the server supplies no value for it, the code defaults to turning the behavior on.
• quiet_spell is also a new reason in web fetch provenance checks, the checks about where fetched web content came from, and it is recorded separately there.

Why

If you step away while Claude is working, subagents no longer pile up repeated approval requests within one turn. A subagent action may simply not happen during that window, so an unanswered prompt can mean later subagent steps were skipped rather than queued for you.
