Use this tool to invoke it.\\n\\nHow to invoke:\\n- Set `skill` to the exact name of an available skill (no leading slash). For plugin-namespaced skills use the fully qualified `plugin:skill` form.\\n- Set `args` to pass optional arguments.\\n\\nImportant:\\n- Available skills are listed in system-reminder messages in the conversation\\n- Only invoke a skill that appears in that list, or one the user explicitly typed as `/<name>` in their message.
