	// For Hermes, redirect HERMES_HOME to a per-task compatibility overlay ONLY
	// when the agent has skills bound. A skill-less Hermes task keeps the user's
	// real home and its original behavior untouched. The overlay makes the bound
	// skills visible — Hermes discovers skills only from its home, so the old
	// .agent_context/skills/ fallback was never read (issue #5242). See
	// hermes_home.go.
	//
	// Note this is a local contract, not an observable product behaviour: the
	// server appends the platform's built-in skills to every agent's skill set
	// (service.LoadAgentSkillBundles), so a claimed task's AgentSkills is never
	// empty and the skill-less branch is effectively unreachable in production.
	// Emptying an agent's own skill list is NOT a way to opt out of the overlay.
