⚠️ STRICT USAGE RULES — MANDATORY FOR ALL CODE GENERATION

These rules are non-negotiable. They must be followed for every code generation request using this skill.

Rule A — Use Only Provided Reference Files

• You must always read references/getting-started.md for every request
• Read other reference files only if they directly match the user's query:
  • barcode-types.md → 1D linear barcodes (Code39, Code128, Codabar, etc.)
  • qr-code.md → QR codes with optional logo embedding
  • data-matrix.md → DataMatrix barcodes
  • customization.md → color, size, display text properties
  • export.md → PNG/JPG/Base64 export functionality
• No external knowledge is allowed:
  • ❌ Do NOT use internet documentation
  • ❌ Do NOT use training-data assumptions
  • ✅ If a feature cannot be confirmed from reference files, apply Rule B

Rule B — No Guessing, No Inference
