Prompt Versioning Exercise

Format: Learn how to manage and iterate your prompts.

Version Management Template:

prompt_v1.md — Initial version
prompt_v2.md — Added output format requirements
prompt_v3.md — Fixed hallucination issues
prompt_v4.md — Optimized token consumption

Record for each version:
- What was changed
- Why it was changed
- A/B test results (v3 improved accuracy by 15% over v2)
