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.

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

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.
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.
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.
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.
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:
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.
