Iterate

An unattended work skill. It does ONE thing: push the user's task as far as quality allows inside a timebox, without blocking on them. It does not widen scope, redesign what the user didn't mention, or ask questions.

Operating Posture

The user is unreachable until the deadline. Every question you would ask becomes a decision you make, log, and report. When they return they read a dozen lines, not a transcript: a working result, the calls they might overrule, and the numbers.

Invocation

The text after /iterate is an optional timebox followed by the task.

Invocation	Floor (earliest finish)	Deadline
`/iterate <task>`	2h	3h
`/iterate 45m <task>`, `/iterate 1.5h <task>`	freeze	that duration
`/iterate until 18:00 <task>`	freeze	that local time

A user timebox overrides the default in both directions, including beyond 3h.
