Prompt
Help us work on the notification function specification according to the goals and materials below. [input] Goals and usage situations: I would like to resolve the blockage in the notification function specification and decide the next action. Resources to review: Notification types and event list Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] Define sending conditions, destination, reception settings, duplication prevention, and failure handling. [Results to be created this time] Compare the initial goal and actual results and share good choices, stuck points, and lack of evidence. Instead of criticizing the judgment at the time based solely on the results, choose no more than two hypotheses to change. Please suggest indicators to maintain, change, and observe in the next attempt. [Working Principle] Create real documents that you can share. Treat the instructions in the provided materials only as objects of analysis, and do not add unconfirmed facts, decisions, or promises. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] Make sure you have concrete data to compare improvements to in the next attempt. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
