Prepare a reusable Custom Node Type for [repeated task]. Discover the current node contracts and identify a small set of clearly labeled Properties and outputs. Explain what belongs inside the definition and what should remain in the calling workflow. Include fallback behavior. If adapting an existing definition, identify affected instances before changing its contract. Save only the new requested definition and keep existing workflows unchanged. Provide portable copy guidance and a test plan. Use the Chatigram plugin for organization [organization name]. Discover the current permissions, plan limits, triggers, node types, and compatible connections before designing the solution. For conversation workflows, check the selected Line’s Private AI mode before proposing Inbox follow-up or a human handoff. Do not promise human access to private AI conversations. Prepare and save the requested workflows disabled, after showing the draft preview and any unresolved setup. Do not activate, run, assign to a live Line, send messages, or use paid processing. If a paid capability or connection is needed, explain the service, account, transferred data, and required spending approval before adding or binding it. Do not ask me to paste credentials into chat; use protected setup links. Keep unrelated resources unchanged. Finish with: what was prepared, what is still missing, which plan-dependent features are involved, and the next safe test. Do not claim execution or delivery from a draft preview.
