What
The Skill tool's result schema now spells out two shapes: an inline result that can carry readOnly, meaning the skill instructions were loaded without executing anything, and a forked result carrying an agent id plus background, meaning a sub-agent was launched and its real outcome arrives later as a task notification.
Details
The input schema tells the model to use a name from the available-skills list and not to guess.
Evidence
The name of a skill from the available-skills list. Do not guess names.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
