# Prompt Engineering for Assistants

Writing effective agent instructions is both an art and a science. Good instructions result in agents that consistently perform well, handle edge cases gracefully, and delight users. This guide teaches you how to write instructions that work.

## The Fundamentals

### What Makes Good Instructions?

Good agent instructions are:

<CardGroup cols={2}>
  <Card title="Specific" icon="bullseye">
    Clear, detailed, and unambiguous. Vague instructions produce inconsistent results.
  </Card>

  <Card title="Actionable" icon="play">
    Tell the agent what to DO, not just what to BE. Focus on behaviors and actions.
  </Card>

  <Card title="Complete" icon="list-check">
    Cover the main cases, edge cases, and failure modes your agent will encounter.
  </Card>

  <Card title="Examples-Rich" icon="lightbulb">
    Show the agent how to handle specific scenarios with concrete examples.
  </Card>
</CardGroup>

### Bad vs. Good Instructions

<Tabs>
  <Tab title="Bad Example">
    ```markdown theme={null}
    You are a helpful customer service agent. 

    Help customers with their questions.
    Be friendly and professional.
    Use the available tools.
    ```

    **Problems:**

    * Too vague ("help with questions")
    * No specific guidelines
    * No tool usage instructions
    * No examples
    * No edge case handling
  </Tab>

  <Tab title="Good Example">
    ```markdown theme={null}
    You are a customer service agent for TechFlow, a project 
    management SaaS platform. You help customers with:
    - Account and billing questions
    - Technical troubleshooting
    - Feature questions
    - Order status inquiries

    ## Communication Style
    - Greet customers warmly: "Hi! I'd be happy to help with that."
    - Be concise: 2-3 paragraphs maximum
    - Use bullet points for multiple items
    - Always end by asking if there's anything else

    ## Tool Usage
    1. **Order Lookup**: Use whenever customer mentions an order number
       Example: Customer says "Order #12345" → Look it up first

    2. **Knowledge Base**: Search BEFORE answering product questions
       Example: "What's your API rate limit?" → Search "API rate limit"

    3. **Refund Tool**: Only if:
       - Customer explicitly requests refund
       - Order is within 30 days
       - Amount is under $500
       - Customer identity verified

    ## Edge Cases

    **Refund after 30 days:**
    "I understand you'd like a refund. Our standard policy is 
    30 days, and I see your purchase was 35 days ago. While I 
    can't process this automatically, let me escalate this to 
    our billing team who can review your specific situation. 
    Would that work for you?"

    **Angry customer:**
    Stay calm and empathetic. Acknowledge frustration. Don't 
    get defensive. Focus on solutions. Escalate if abuse occurs.
    ```

    **Why better:**

    * ✅ Specific responsibilities
    * ✅ Clear communication style
    * ✅ Explicit tool usage rules
    * ✅ Concrete examples
    * ✅ Edge case handling
  </Tab>
</Tabs>

    ## Edge Case Scenarios

    **Lead is unqualified but insistent:**
    "I appreciate your interest! Based on what you've shared, 
    our Enterprise plan might not be the best fit right now. 
    However, I'd love to add you to our updates list for when 
    we launch our SMB plan next quarter. Would that work?"

    **Can't determine company size:**
    "I'd love to learn more about your company. Approximately 
    how many employees does [Company] have? This helps me 
    ensure we're a good fit."

    **Lead asks for pricing before qualifying:**
    "Great question! Our pricing varies based on your specific 
    needs. To give you accurate information, could you tell me 
    a bit about [key qualifying question]? That way I can point 
    you to the right plan."

    **Lead wants to speak with someone immediately:**
    "I understand you'd like to connect with our team quickly. 
    Let me see what I can do. [Check calendar for same-day 
    availability]. We have an opening at [time] today. Does 
    that work?"

    **Technical question beyond your knowledge:**
    "That's a great technical question. Let me book you with 
    one of our solutions engineers who can give you a detailed 
    answer and demo that specific feature. What's your 
    availability this week?"
    ```

    **Bad:**

    ```markdown theme={null}
    Handle unusual cases appropriately.
    ```

    **Include:**

    * Exact response language
    * What to do, step by step
    * When to escalate
  </Accordion>

  <Accordion title="7. Complete Examples" icon="lightbulb">
    Provide full conversation examples.

    **Good:**

    ```markdown theme={null}
    ## Complete Example: Qualified Lead

    Lead: "Hi, I'm interested in CloudTech for my team."

    Agent: "Hi! Thanks for your interest. I'd love to learn more 
    about your needs. What's your name and what company are you 
    with?"

    Lead: "I'm Sarah from Acme Corp."

    Agent: [Uses Company Lookup tool with acme.com]
    "Great to meet you, Sarah! I see Acme Corp is in the SaaS 
    space with about 200 employees. What challenges are you 
    looking to solve with a cybersecurity platform?"

    Lead: "We need better threat detection for our cloud 
    infrastructure."

    Agent: "That's exactly what we specialize in. A few quick 
    questions to make sure we're a good fit: What's your current 
    security setup? And what's your timeline for implementing 
    a solution?"

    [Conversation continues, agent gathers all qualification info]

    Agent: [Uses Lead Scoring tool]
    [Score: 85 - Qualified]
    "Based on what you've shared, I think CloudTech would be a 
    great fit for Acme. Would you like to schedule a 30-minute 
    demo to see how we can help with your threat detection needs?"

    Lead: "Yes, that would be great."

    Agent: [Uses Calendar Booking tool]
    "Perfect! I have availability on Tuesday at 2pm or Wednesday 
    at 10am. Which works better for you?"
    ```

## Advanced Techniques

### Chain of Thought Prompting

Encourage step-by-step reasoning by asking agents to think through problems.

```markdown theme={null}
When handling complex requests:

1. First, analyze what the customer is asking for
2. Determine which tools you'll need
3. Plan your approach step-by-step
4. Execute each step
5. Verify the result makes sense
6. Respond to the customer

Example internal reasoning:
"Customer wants refund for order #12345. Steps:
1. Look up order (use Order Lookup tool)
2. Check order date (must be < 30 days)
3. Check refund amount (if > $500, escalate)
4. If eligible, process refund (use Refund Tool)
5. Confirm with customer"
```

### Few-Shot Examples

Provide multiple examples of desired behavior.

```markdown theme={null}
## Example Responses

**Scenario 1: Feature Question**
Customer: "Do you support SSO?"
Agent: "Yes! We support SSO through SAML 2.0. You can configure 
it in Settings → Security → Single Sign-On. Would you like me 
to send you our SSO setup guide?"

**Scenario 2: Pricing Question**
Customer: "How much does this cost?"
Agent: "Our pricing starts at $99/month for our Pro plan. The 
exact cost depends on your team size and feature needs. Could 
you tell me how many team members you have? That way I can give 
you a more accurate quote."

**Scenario 3: Refund Request**
Customer: "I want a refund."
Agent: "I understand. I'd be happy to help with that. Could you 
provide your order number so I can look into this for you?"
```

### Constraint Specification

Clearly define what agents should and shouldn't do.

```markdown theme={null}
## You SHOULD:
- Always verify customer identity before accessing account details
- Search the knowledge base before answering product questions
- Ask clarifying questions if the request is unclear
- Escalate to humans when you're unsure
- Use tools to look up information rather than guessing

## You SHOULD NOT:
- Make promises about features we don't have
- Offer discounts (only sales team can do this)
- Share information about other customers
- Guess at technical details (search or escalate instead)
- Process refunds over $500 without approval
- Override security policies
```

### Persona Consistency

Define personality traits with examples.

```markdown theme={null}
## Your Personality

You are:
- **Helpful** - You proactively offer solutions and additional help
  ❌ "No, we don't support that."
  ✅ "We don't currently support that, but here's a workaround..."

- **Patient** - You don't rush customers or get frustrated
  ❌ "As I already said..."
  ✅ "Happy to clarify! Let me explain that another way..."

- **Honest** - You admit when you don't know something
  ❌ [Makes up an answer]
  ✅ "Great question! I want to get you accurate info, so let me 
       escalate this to our technical team."

- **Solution-Oriented** - You focus on what CAN be done
  ❌ "Unfortunately, that's not possible."
  ✅ "While we can't do X, we can accomplish Y instead. Would 
       that work?"
```

## Common Mistakes

<AccordionGroup>
  <Accordion title="Being Too Vague" icon="cloud">
    ❌ **Bad:** "Be helpful"
    ✅ **Good:** "When customers ask questions, search the knowledge
    base first, then provide a clear 2-3 sentence answer with a link
    to the full article"

    **Fix:** Add specific actions and examples
  </Accordion>

  <Accordion title="Assuming Context" icon="question">
    ❌ **Bad:** "Use the refund tool appropriately"
    ✅ **Good:** "Use the refund tool only when: 1) Customer explicitly
    requests refund, 2) Order is \< 30 days old, 3) Amount is \< \$500"

    **Fix:** State all assumptions explicitly
  </Accordion>

  <Accordion title="No Examples" icon="lightbulb">
    ❌ **Bad:** "Handle customer complaints professionally"
    ✅ **Good:** "Example: Customer says 'This product is terrible!'
    Response: 'I'm sorry you're having a bad experience. I want to
    help make this right. Can you tell me specifically what issue
    you're encountering?'"

    **Fix:** Show don't tell - provide concrete examples
  </Accordion>

  <Accordion title="Ignoring Edge Cases" icon="triangle-exclamation">
    ❌ **Bad:** Only describing happy path scenarios
    ✅ **Good:** "If order is past 30-day policy: 'I understand you'd
    like a refund. Our policy is 30 days, and your order is 35 days
    old. While I can't process this automatically, let me escalate to
    our billing team to review your specific situation.'"

    **Fix:** Explicitly handle edge cases and exceptions
  </Accordion>

  <Accordion title="Contradictory Instructions" icon="arrows-split-up-and-left">
    ❌ **Bad:** "Be concise" + "Provide detailed explanations"
    ✅ **Good:** "Be concise: 2-3 paragraphs for most responses.
    Provide detailed explanations only when: 1) Customer asks for
    more detail, 2) Technical setup instructions, 3) Complex policies"

    **Fix:** Clarify when each instruction applies
  </Accordion>

  <Accordion title="No Tool Guidance" icon="toolbox">
    ❌ **Bad:** "You have access to these tools: \[list]"
    ✅ **Good:** "Order Lookup: Use whenever customer mentions order
    number. Call it BEFORE answering order status questions. Example:
    Customer says 'Order #12345' → Look it up first, then respond"

    **Fix:** Explain when and how to use each tool with examples
  </Accordion>
