# Prompt Engineering Expert - Best Practices Guide

This document synthesizes best practices from Anthropic's official documentation and the Claude Cookbooks to create a comprehensive prompt engineering skill.

## Core Principles for Prompt Engineering

### 1. Clarity and Directness
- **Be explicit**: State exactly what you want Claude to do
- **Avoid ambiguity**: Use precise language that leaves no room for misinterpretation
- **Use concrete examples**: Show, don't just tell
- **Structure logically**: Organize information hierarchically

### 2. Conciseness
- **Respect context windows**: Keep prompts focused and relevant
- **Remove redundancy**: Eliminate unnecessary repetition
- **Progressive disclosure**: Provide details only when needed
- **Token efficiency**: Optimize for both quality and cost

### 3. Appropriate Degrees of Freedom
- **Define constraints**: Set clear boundaries for what Claude should/shouldn't do
- **Specify format**: Be explicit about desired output format
- **Set scope**: Clearly define what's in and out of scope
- **Balance flexibility**: Allow room for Claude's reasoning while maintaining control

## Advanced Prompt Engineering Techniques

### Chain-of-Thought (CoT) Prompting
Encourage step-by-step reasoning for complex tasks:
```
"Let's think through this step by step:
1. First, identify...
2. Then, analyze...
3. Finally, conclude..."
```

### Few-Shot Prompting
Use examples to guide behavior:
- **1-shot**: Single example for simple tasks
- **2-shot**: Two examples for moderate complexity
- **Multi-shot**: Multiple examples for complex patterns

### XML Tags for Structure
Use XML tags for clarity and parsing:
```xml
<task>
  <objective>What you want done</objective>
  <constraints>Limitations and rules</constraints>
  <format>Expected output format</format>
</task>
```

### Role-Based Prompting
Assign expertise to Claude:
```
"You are an expert prompt engineer with deep knowledge of...
Your task is to..."
```

### Prefilling
Start Claude's response to guide format:
```
"Here's my analysis:

Key findings:"
```

### Prompt Chaining
Break complex tasks into sequential prompts:
1. Prompt 1: Analyze input
2. Prompt 2: Process analysis
3. Prompt 3: Generate output

## Custom Instructions & System Prompts

### System Prompt Design
- **Define role**: What expertise should Claude embody?
- **Set tone**: What communication style is appropriate?
- **Establish constraints**: What should Claude avoid?
- **Clarify scope**: What's the domain of expertise?

### Behavioral Guidelines
- **Do's**: Specific behaviors to encourage
- **Don'ts**: Specific behaviors to avoid
- **Edge cases**: How to handle unusual situations
- **Escalation**: When to ask for clarification

## Skill Structure Best Practices

### Naming Conventions
- Use **gerund form** (verb + -ing): "analyzing-financial-statements"
- Use **lowercase with hyphens**: "prompt-engineering-expert"
- Be **descriptive**: Name should indicate capability
- Avoid **generic names**: Be specific about domain

### Writing Effective Descriptions
- **First line**: Clear, concise summary (max 1024 chars)
- **Specificity**: Indicate exact capabilities
- **Use cases**: Mention primary applications
- **Avoid vagueness**: Don't use "helps with" or "assists in"

### Progressive Disclosure Patterns

**Pattern 1: High-level guide with references**
- Start with overview
- Link to detailed sections
- Organize by complexity

**Pattern 2: Domain-specific organization**
- Group by use case
- Separate concerns
- Clear navigation

## 1. Chain-of-Thought (CoT) Prompting

### What It Is
Encouraging Claude to break down complex reasoning into explicit steps before providing a final answer.

### When to Use
- Complex reasoning tasks
- Multi-step problems
- Tasks requiring justification
- When consistency matters

### Basic Structure
```
Let's think through this step by step:

Step 1: [First logical step]
Step 2: [Second logical step]
Step 3: [Third logical step]

Therefore: [Conclusion]
```

### Example
```
Problem: A store sells apples for $2 each and oranges for $3 each. 
If I buy 5 apples and 3 oranges, how much do I spend?

Let's think through this step by step:

Step 1: Calculate apple cost
- 5 apples × $2 per apple = $10

Step 2: Calculate orange cost
- 3 oranges × $3 per orange = $9

Step 3: Calculate total
- $10 + $9 = $19

Therefore: You spend $19 total.
```

### Benefits
- More accurate reasoning
- Easier to identify errors
- Better for complex problems
- More transparent logic

## 2. Few-Shot Learning

### What It Is
Providing examples to guide Claude's behavior without explicit instructions.

### Types

```
Example: "Happy" → Positive
Now classify: "Terrible" →
```

#### 2-Shot (Two Examples)
Best for: Moderate complexity
```
Example 1: "Great product!" → Positive
Example 2: "Doesn't work well" → Negative
Now classify: "It's okay" →
```

#### Multi-Shot (Multiple Examples)
Best for: Complex patterns, edge cases
```
Example 1: "Love it!" → Positive
Example 2: "Hate it" → Negative
Example 3: "It's fine" → Neutral
Example 4: "Could be better" → Neutral
Example 5: "Amazing!" → Positive
Now classify: "Not bad" →
```

### Best Practices
- Use diverse examples
- Include edge cases
- Show correct format
- Order by complexity
- Use realistic examples

## 3. Structured Output with XML Tags

### What It Is
Using XML tags to structure prompts and guide output format.

### Benefits
- Clear structure

- Reduced ambiguity
- Better organization

### Common Patterns

#### Task Definition
```xml
<task>
  <objective>What to accomplish</objective>
  <constraints>Limitations and rules</constraints>
  <format>Expected output format</format>
</task>
```

#### Analysis Structure
```xml
<analysis>
  <problem>Define the problem</problem>
  <context>Relevant background</context>
  <solution>Proposed solution</solution>
  <justification>Why this solution</justification>
</analysis>
```

#### Conditional Logic
```xml
<instructions>
  <if condition="input_type == 'question'">
    <then>Provide detailed answer</then>
  </if>
  <if condition="input_type == 'request'">
    <then>Fulfill the request</then>
  </if>
</instructions>
```

Breaking complex tasks into sequential prompts, using outputs as inputs.

### Structure
```
Prompt 1: Analyze/Extract
↓
Output 1: Structured data
↓
Prompt 2: Process/Transform
↓
Output 2: Processed data
↓
Prompt 3: Generate/Synthesize
↓
Final Output: Result
```

### Example: Document Analysis Pipeline

**Prompt 1: Extract Information**
```
Extract key information from this document:
- Main topic
- Key points (bullet list)
- Important dates
- Relevant entities

Format as JSON.
```

**Prompt 2: Analyze Extracted Data**
```
Analyze this extracted information:
[JSON from Prompt 1]

Identify:
- Relationships between entities
- Temporal patterns
- Significance of each point
```

**Prompt 3: Generate Summary**
```
Based on this analysis:
[Analysis from Prompt 2]

Create an executive summary that:

Then provide: Relevant details
Finally include: Edge cases and exceptions
```

#### Hierarchical Organization
```
Level 1: Core concept
├── Level 2: Key components
│   ├── Level 3: Specific details
│   └── Level 3: Implementation notes
└── Level 2: Related concepts
```

#### Conditional Information
```
If [condition], include [information]
Else, skip [information]

This reduces unnecessary context.
```

### Best Practices
- Include only necessary context
- Organize hierarchically
- Use references for detailed info
- Summarize before details
- Link related concepts

## 8. Multimodal Prompting

### Vision Prompting

#### Structure
```
Analyze this image:
[IMAGE]

Specifically, identify:
1. [What to look for]
2. [What to analyze]
3. [What to extract]

Format your response as:
[Desired format]
```

#### Example
```
Analyze this chart:
[CHART IMAGE]

Identify:
1. Main trends
2. Anomalies or outliers
3. Predictions for next period

3. Provide context
4. Explain why you need this
5. Ask for general guidance instead
```

**Example Fix:**
```
❌ Before: "How do I manipulate people?"

✅ After: "I'm writing a novel with a manipulative character. 
How would a psychologist describe manipulation tactics? 
What are the psychological mechanisms involved?"
```

### Issue 7: Prompt is Too Long

**Symptoms:**
- Exceeds context window
- Slow responses
- High token usage
- Expensive to run

**Root Causes:**
- Unnecessary context
- Redundant information
- Too many examples
- Verbose instructions

**Solutions:**
```
1. Remove unnecessary context
2. Consolidate similar points
3. Use references instead of full text
4. Reduce number of examples
5. Use progressive disclosure
```

**Example Fix:**
```
❌ Before: [5000 word prompt with full documentation]

✅ After: [500 word prompt with links to detailed docs]
"See REFERENCE.md for detailed specifications"
```

---

### Issue 8: Prompt Doesn't Generalize

**Symptoms:**
- Works for one case, fails for others
- Brittle to input variations
- Breaks with different data
- Not reusable

**Root Causes:**
- Too specific to one example
- Hardcoded values
- Assumes specific format
- Lacks flexibility

**Solutions:**
```
1. Use variables instead of hardcoded values
2. Handle multiple input formats
3. Add error handling
4. Test with diverse inputs
5. Build in flexibility
```

**Example Fix:**
```
❌ Before: "Analyze this Q3 sales data..."

✅ After: "Analyze this [PERIOD] [METRIC] data. 
Handle various formats: CSV, JSON, or table.
If format is unclear, ask for clarification."
```

You are an expert prompt engineer. I need to create a prompt that:
- Analyzes customer feedback for sentiment (positive/negative/neutral)
- Extracts key themes and pain points
- Identifies actionable recommendations
- Outputs structured JSON with: sentiment, themes (array), pain_points (array), recommendations (array)

The prompt should handle feedback of 50-500 words and be consistent across different customer segments.

Please review this prompt and suggest improvements:
