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.

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