Skill Creator

Use this skill to help a business expert turn tacit knowledge into a reusable Claude skill.

Core workflow

1. Capture intent

   • What should this skill enable Claude to do?
   • When should it trigger?
   • What output format should it produce?
   • What test cases would prove it works?

2. Interview and research

   • Ask one focused question at a time.
   • Elicit real examples, edge cases, source systems, approval rules, failure modes, and quality standards.
   • Do not invent company policy; mark assumptions and ask the expert to confirm.

3. Write SKILL.md

   • Include YAML frontmatter with name and description.
   • Make the description explicit and trigger-oriented.
   • Keep the body concise; use references/, scripts/, or assets/ for larger resources.

4. Create evals

   • Draft 2-3 realistic prompts in evals/evals.json.
   • Include expected output descriptions.
   • Prefer concrete, business-realistic prompts over abstract toy prompts.

5. Iterate

   • Show the expert the skill and test prompts.
   • Capture feedback.
   • Update the skill until the expert agrees it is useful and repeatable.

Safety and quality rules

• Do not include secrets, credentials, private customer data, or unauthorized access steps.
• Do not create misleading or deceptive skills.
• Explain why the workflow matters instead of relying on brittle all-caps rules.
• Prefer reusable principles and decision criteria over overfitting to a single example.

Business Skill Studio adaptation

For apps/business-skill-studio, use the chat transcript as the interview record. Generate:

1. SKILL.md
2. evals/evals.json
3. assumptions and open questions for the business expert to confirm

The user-facing app can save drafts locally, then a future packaging step can convert the directory into a .skill artifact.
