Bottle the useful parts of a good session. A weekly report often involves the same decisions: which inputs count, how to group the data, what the chart should show and what needs a human check. If you keep explaining those choices, you have the ingredients for a reusable workflow. ## Decide what should be reused A prompt template works when you mostly need to supply different facts to a familiar request. A script works when a fixed transformation can be expressed as code. A skill works when there is a recognizable goal with several steps, references or tools. A schedule decides when work runs. These are complementary pieces, and a useful workflow may use more than one. OpenAI describes a skill as a folder with SKILL.md and optional resources. Its instructions explain how to carry out a workflow. Connected tools provide access to live data and actions; a skill does not create that access by itself. Keep those roles clear when a reusable request depends on a service. ## Extract the method from a successful result Use a finished example as the reference. Identify the input format, the decisions that required judgment, the output structure and the checks you performed. Preserve those in a short workflow description. Do not turn every accidental detail of the session into a rule. For a weekly feedback brief, the reusable method might be: read the supplied export, group comments by theme, retain source identifiers, distinguish repeated complaints from isolated examples, and produce a one-page brief plus an exceptions list. The particular comments and this week’s date belong in the input. ### A request you can adapt Turn our verified feedback-report workflow into a reusable skill for this project. Include when to use it, required inputs, steps, expected output, missing-data behavior and review checks. Use the accepted report as a format example. Keep customer data and this week’s findings out of the skill. Show me how to invoke and test it. ## Teach the workflow how to stop usefully A reusable process must handle the day something is missing. What if the export has a new column name? What if no comments arrived? What if a connected source is unavailable? Write a useful result for each case: an empty-period report, a schema warning or an explicit “not refreshed” status. Try the workflow with a small awkward input before you rely on it. Remove a required field. Insert two conflicting source records. Check whether the report preserves the uncertainty. A procedure that only works on the example used to create it is still a prototype. ## Schedule only after the manual run is useful The official scheduled-task guidance recommends testing the prompt manually first. For your recurring task, specify the source, period, output, notification condition and stopping rule. A daily schedule is not a guarantee that a source has new data. Define what “no change” means. For local work, verify the execution environment’s availability and permissions. Review the first few runs. Keep the report useful when a refresh fails by showing the last successful input date and the reason for the failure. A scheduled task should reduce surprise, not move it into the background. ### A request you can adapt After we verify a manual run, set up a weekly draft report from [approved source] for [period and timezone]. Include source timestamps and unresolved exceptions. If a required source is unavailable, report that and do not fill the gap. Notify me when the report is ready or needs attention. Prepare files for review; do not send them to anyone. ## Take this into your next task Reuse the method, supply fresh inputs, and make failure behavior part of the workflow before scheduling it.

A connector or another authorized tool supplies service access. A workflow can also use only local files and code. ## Sources and editorial notes Reviewed September 6, 2026.
