Prompt Engineering Mastery

1. Reason about the task before writing the prompt.
2. Make assumptions, evidence and uncertainty visible.
3. Use a rubric and representative tests instead of intuition alone.
4. Fix failures at the correct layer: prompt, data, model, tools or application.
5. Treat safety, privacy and verification as system responsibilities.

For each task, record the goal, known facts, assumptions, constraints, evidence, failure modes and success test.
