System Prompts

Write effective system prompts to define your agent’s behavior, capabilities, and personality

System prompts are the foundation of your agent’s behavior. They provide instructions, context, and guidelines that shape how your agent responds and acts.

What is a System Prompt?

A system prompt is a set of instructions sent to the AI model before every conversation. It defines:

• Role & Personality: Who the agent is and how it should communicate
• Capabilities: What the agent can and cannot do
• Guidelines: Rules and best practices for the agent to follow
• Context: Background information and domain knowledge

Default System Prompt

Kortix agents start with a comprehensive default prompt:

You are Kortix, an autonomous AI Worker created by the Kortix team.

You are a highly capable AI agent designed to work alongside users on 
complex tasks. You operate in a cloud workspace environment with access 
to file system, terminal, browser, and various specialized tools.

# Tone and style
- Your responses should be short and concise
- Use Github-flavored markdown for formatting
- Only use emojis if explicitly requested
- Output text to communicate; use tools to complete tasks
- Never create files unless absolutely necessary

# Professional objectivity
Prioritize technical accuracy and truthfulness. Focus on facts and 
problem-solving. Provide direct, objective technical info without 
unnecessary validation or excessive praise.

# Task Management
Use task management tools frequently to track progress and plan work.
Break down complex tasks into smaller steps. Mark tasks as completed
immediately after finishing.

...

The full default prompt is defined in backend/core/prompts/core_prompt.py and includes detailed guidance on tool usage, file operations, and communication protocols.

Customizing System Prompts

Basic Customization

1. Access Prompt Editor

   Navigate to your agent’s configuration page and click Edit System Prompt.

2. Define Agent Role

   Start with a clear role definition:

   You are a Customer Support Specialist for Acme Corp, a SaaS company
   providing project management tools. Your role is to help customers
   resolve issues, answer questions, and provide guidance.
   
3. Add Capabilities

   Specify what the agent can do:

   # Your Capabilities
   - Access customer data from our CRM
   - Create and update support tickets
   - Search documentation and knowledge base
   - Escalate complex issues to human agents
   - Provide product usage guidance
   
4. Set Guidelines

   Define how the agent should behave:

   # Guidelines
   - Always greet customers warmly and professionally
   - Ask clarifying questions before making assumptions
   - Provide step-by-step solutions when possible
   - Never share customer data with other customers
   - Escalate billing issues to the finance team

Testing Your Prompts

1. Make Changes

   Update your system prompt in the agent builder.

2. Start Test Conversation

   Create a new thread to test the updated behavior.

3. Evaluate Responses

   Check if the agent:

   • Follows the instructions
   • Uses the right tone and style
   • Applies domain knowledge correctly
   • Uses tools appropriately
4. Iterate

   Refine your prompt based on test results. Common adjustments:

   • Add more specific examples
   • Clarify ambiguous instructions
   • Add constraints for edge cases
   • Improve formatting and structure

Prompt Best Practices

Be Specific and Clear

Bad: “Be helpful and nice”

Good: “Greet users warmly, ask clarifying questions before providing solutions, and always verify if the solution worked before ending the conversation.”

Specificity prevents ambiguity and ensures consistent behavior.

Use Examples

Show the agent exactly what you want:

When explaining technical concepts, use this format:

Example:
**Concept**: API Rate Limiting
**Simple Explanation**: Imagine a store that only lets 100 people in per hour
**Technical Details**: Rate limiting restricts API calls to prevent abuse...

Examples are more effective than abstract descriptions.

Structure with Headings

Use markdown headings to organize your prompt:

# Role
You are a...

# Capabilities
- Capability 1
- Capability 2

# Guidelines
1. Guideline 1
2. Guideline 2

# Response Format
...

Structure helps the model parse and follow instructions.

Avoid Over-Constraining

Too Restrictive: “Only answer questions about feature X. Never discuss anything else.”

Better: “Your primary expertise is feature X. For questions about other features, provide basic guidance and suggest consulting the relevant specialist.”

Allow flexibility while maintaining focus.

Update Based on Usage

Monitor agent conversations and update prompts when you notice:

• Repeated mistakes or misunderstandings
• Missing information in responses
• Inconsistent tone or style
• Misuse of tools or integrations

Prompt engineering is iterative.

API Integration

Update system prompts programmatically:

Python

import requests

system_prompt = """
You are a Sales Assistant for Acme Corp.

# Your Role
Help sales teams manage leads, track deals, and close sales.

# Capabilities
- Access CRM data
- Schedule meetings
- Generate quotes
- Track pipeline metrics
"""

response = requests.put(
    f"https://api.kortix.com/agents/{agent_id}",
    json={"system_prompt": system_prompt},
    headers=headers
)

print(f"Updated to version {response.json()['current_version']['version_name']}")

System prompt changes automatically create a new agent version.

Common Patterns

Chain of Thought

Encourage step-by-step reasoning:

When solving problems:
1. Break down the problem into smaller parts
2. Think through each part carefully
3. Explain your reasoning at each step
4. Verify your solution makes sense

Self-Correction

Teach agents to verify their work:

Before providing a final answer:
1. Review your solution for errors
2. Check if it fully addresses the question
3. Verify any calculations or logic
4. Consider edge cases or exceptions

Uncertainty Handling

Define how to handle unknown information:

If you're unsure about something:
1. State your uncertainty clearly
2. Explain what you do know
3. Suggest ways to find the answer
4. Offer to search for information if helpful

Never make up information or guess.
