GitHubCopilotAgent never forwarded the Copilot SDK's skill_directories (and disabled_skills) parameters to create_session/resume_session, so native Copilot CLI skills could not be configured through the agent. Add both as fields on GitHubCopilotOptions and forward them (with runtime-override and empty-list-clears-defaults semantics matching instruction_directories) in _create_session and _resume_session.
