The instruction text is present; where it enters a prompt is decided at runtime.

What

New instruction text tells a coordinator session that when it uses the Skill tool, the skill is only loaded and not run: no forking, no permission grants, no hooks and no preamble shell commands. Execution happens in worker sessions instead. The text is present in this build; where it is included in a prompt is decided at runtime.

Evidence

no fork, no permission grants, no hooks, no preamble shell commands

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
