Don Cheli: Specification Generator

Instructions

  1. Read the proposal or requirement description
  2. Generate Gherkin .feature file with scenarios grouped by priority (P1/P2/P3+)
  3. Auto-generate DBML schema from the entities mentioned in scenarios
  4. Include happy paths AND sad paths for P1 scenarios
  5. Mark ambiguities with [NEEDS CLARIFICATION]
  6. Apply the project's constitution principles

Quality Gate

  • Every P1 scenario must have at least one sad path
  • Every entity must appear in the DBML schema
  • Tag as @draft until clarification passes

Do not use this skill when

  • The user is asking for a quick fix (use rapid mode instead)
