First detect a compatible installation and shell. Read the installed current upstream Skill instead of assuming paths or behavior from an old version.\n\nThe native runtime is optional. Do not install, update, import credentials, pair agents, or change configuration unless the user requested that mutation. If no native runtime exists, return to the portable specialist workflow and use host capabilities where equivalent.\n"
