Design or improve skills to be reused based on the following data. [input] AI and execution environment to use: Codex desktop app, skills used in local projects Existing report and scope to update: Service plan comparison table created last month and changes made this month Conditions to maintain and scope of work: Written in Korean. Existing files are preserved. Provides registration files and verification methods without assuming tools that do not exist. [Tasks to be solved in this skill] Create a skill to compare previous research and currently confirmed data and classify them as changeable, maintainable, or unconfirmable. Record the basis for changes in price, function, and schedule and when they were confirmed, and do not conclude that the function will be terminated just because the link disappears. Please print out the report revisions and list of changes. Please handle regular execution or notification settings only when specifically requested. [Output for registration] Check the skill format supported by the usage environment and write the entire SKILL.md that can be saved immediately. The name·description should reveal the function and point of use, and the body should include work flow, input, output, exception handling, and completion criteria. Add reference materials, scripts, and templates only when actually needed, and distinguish the path and contents of each file. The registration location and calling method will be guided based on confirmed environmental information. If you can't create or test the file yourself, provide the content and mark it as not running. Do not create tools/paths/installations that you have not confirmed. If important information is missing, only ask questions that will change the outcome first. [Case to be verified] Provide example requests and expected behavior, including price changes, temporary access failures, and cases where the facts are the same but the wording has changed. Distinguish between the actually performed verification and the proposed verification, and if there is a failure, let me know what needs to be corrected.
