A practical review loop, not a score
Draft one workflow
Choose a task you repeat and write the first version of its inputs, rules, and output.
Review all 20 checks
Use the checklist to find unclear assumptions, missing boundaries, and weak deliverables.
Test, revise, repeat
Run normal and difficult examples, then update the workflow wherever the result breaks down.
Review every stage of the workflow
A missing check is a prompt to investigate, not an automatic failure. The goal is to make the workflow easier to understand, run, and improve.
Define the job
- The skill solves one recurring problem.
- The intended user and context are explicit.
- Success can be observed in the output.
- A normal one-off prompt would not be enough.
Collect the right inputs
- Required information is separated from optional detail.
- The skill asks focused follow-up questions.
- Missing information is handled instead of invented.
- Sensitive information is not requested unnecessarily.
Specify behavior
- Priorities and decision rules are concrete.
- The answer format is defined.
- Boundaries and prohibited behavior are stated.
- Uncertainty and verification requirements are clear.
Design the deliverable
- The final output is usable outside the conversation.
- Sections appear in a stable order.
- Recommendations are prioritized where relevant.
- The result can be edited or reused.
Test the skill
- An ideal input produces the intended structure.
- Missing context triggers useful questions.
- Conflicting instructions do not break the workflow.
- At least one difficult edge case has been tested.
