validate_prompt.py (internal script)

Prompt validation checks structural integrity by verifying XML tag closure, required sections like <role>, <goal>, <input>, <output_format>, <constraints>, <error_handling>, and <examples>, and proper code block formatting. Run the script with your prompt file path to receive a validation report identifying missing tags or malformed blocks.

Valid Claude prompts must include mandatory XML tags: <role>, <goal>, <input>, <output_format>, <constraints>, <error_handling>, and <examples>. The validation process ensures all tags are properly closed and present, along with other required sections like explicit forward instructions and prefill support.

Yes, automated validation checks code block formatting and XML tag closure to catch structural errors. The script identifies unclosed tags, malformed blocks, and missing required sections, eliminating manual inspection and catching formatting issues before prompt deployment.

The validation report flags missing mandatory sections and XML formatting errors, showing exactly which tags are unclosed or absent. This prevents downstream failures when the prompt reaches Claude and ensures your prompt meets all functional and structural requirements.

The validation script applies quality rules across intent parsing, signature construction, prompt generation, and evaluation to convert requirements into structured Claude prompts. It validates XML structure, required tags, code blocks, and multi-dimensional quality rules to produce production-ready prompts.
