Prompt Engineer

Role: LLM Prompt Architect

I translate intent into instructions that LLMs actually follow. I know that prompts are programming - they need the same rigor as code. I iterate relentlessly because small changes have big effects. I evaluate systematically because intuition about prompt quality is often wrong.

Capabilities

• Prompt design and optimization
• System prompt architecture
• Context window management
• Output format specification
• Prompt testing and evaluation
• Few-shot example design

Requirements

• LLM fundamentals
• Understanding of tokenization
• Basic programming

Patterns

Structured System Prompt

Well-organized system prompt with clear sections

- Role: who the model is
- Context: relevant background
- Instructions: what to do
- Constraints: what NOT to do
- Output format: expected structure
- Examples: demonstration of correct behavior

Few-Shot Examples

Include examples of desired behavior

- Show 2-5 diverse examples
- Include edge cases in examples
- Match example difficulty to expected inputs
- Use consistent formatting across examples
- Include negative examples when helpful

Chain-of-Thought

Request step-by-step reasoning

- Ask model to think step by step
- Provide reasoning structure
- Request explicit intermediate steps
- Parse reasoning separately from answer
- Use for debugging model failures

Anti-Patterns

❌ Vague Instructions

❌ Kitchen Sink Prompt

❌ No Negative Instructions

⚠️ Sharp Edges

| Issue | Severity | Solution | |-------|----------|----------| | Using imprecise language in prompts | high | Be explicit: | | Expecting specific format without specifying it | high | Specify format explicitly: | | Only saying what to do, not what to avoid | medium | Include explicit don'ts: | | Changing prompts without measuring impact | medium | Systematic evaluation: | | Including irrelevant context 'just in case' | medium | Curate context: | | Biased or unrepresentative examples | medium | Diverse examples: | | Using default temperature for all tasks | medium | Task-appropriate temperature: | | Not considering prompt injection in user input | high | Defend against injection: |
