## Overview
|
|
|
|
You can customize the system prompt in two ways:
|
|
|
|
1. Extend the default system prompt with additional instructions
|
|
2. Override the default system prompt entirely
|
|
|
|
<Note>
|
|
Custom system prompts allow you to modify the agent's behavior at a
|
|
fundamental level. Use this feature carefully as it can significantly impact
|
|
the agent's performance and reliability.
|
|
</Note>
|
|
|
|
### Extend System Prompt (recommended)
|
|
|
|
To add additional instructions to the default system prompt:
|
|
|
|
```python
|
|
extend_system_message = """
|
|
REMEMBER the most important RULE:
|
|
ALWAYS open first a new tab and go first to url wikipedia.com no matter the task!!!
|
|
"""
|
|
```
|
|
|
|
### Override System Prompt
|
|
|
|
<Warning>
|
|
Not recommended! If you must override the [default system
|
|
prompt](https://github.com/browser-use/browser-use/blob/main/browser_use/agent/system_prompt.md),
|
|
make sure to test the agent yourself.
|
|
</Warning>
|
|
|
|
Anyway, to override the default system prompt:
|
|
|
|
```python
|
|
# Define your complete custom prompt
|
|
override_system_message = """
|
|
You are an AI agent that helps users with web browsing tasks.
|
|
|
|
[Your complete custom instructions here...]
|
|
"""
|
|
|
|
# Create agent with custom system prompt
|
|
agent = Agent(
|
|
task="Your task here",
|
|
llm=ChatOpenAI(model='gpt-4'),
|
|
override_system_message=override_system_message
|
|
)
|
|
```
|
|
|
|
### Extend Planner System Prompt
|
|
|
|
You can customize the behavior of the planning agent by extending its system prompt:
|
|
|
|
```python
|
|
extend_planner_system_message = """
|
|
PRIORITIZE gathering information before taking any action.
|
|
Always suggest exploring multiple options before making a decision.
|
|
"""
|
|
|
|
# Create agent with extended planner system prompt
|
|
llm = ChatOpenAI(model='gpt-4o')
|
|
planner_llm = ChatOpenAI(model='gpt-4o-mini')
|
|
|
|
agent = Agent(
|
|
task="Your task here",
|
|
llm=llm,
|
|
planner_llm=planner_llm,
|
|
extend_planner_system_message=extend_planner_system_message
|
|
)
|
|
```
