Pixelagent: An Agent Engineering Blueprint
We see agents as the intersection of an LLM, storage, and orchestration. Pixeltable unifies this interface into a single declarative framework, making it the de-facto choice for engineers to build custom agentic applications with build-your-own functionality for memory, tool-calling, and more.
Build your own agent framework:
- Data Orchestration and Storage: Built on Pixeltable's data infrastructure
- Native Multimodal: Built-in support for text, images, audio and video
- Declarative Model: A type-safe python framework
- Model agnostic: Extensible to multiple providers
- Observability: Complete traceability with automatic logging of messages, tool calls, and performance metrics
- Agentic Extensions: Add reasoning, reflection, memory, knowledge, and team workflows.
Connect blueprints to Cursor, Windsurf, Cline:
Plug-and-Play Extensions
- Tools: Add custom python functions as tools
- Memory: Implement long-term memory systems with semantic search capabilities
- Reflection: Add self-improvement loops
- Reasoning: Add planning loops
- Multimodal Agentic Rag: Multimodal agentic retrieval
Usage
Transform your agent blueprint into a distributable package on PyPI, extending the build-your-own philosophy to deployment and sharing.
Installation
```bash pip install pixelagent
Install provider-specific dependencies
pip install anthropic # For Claude models pip install openai # For GPT models ```
Quick Start
```python from pixelagent.anthropic import Agent # Or from pixelagent.openai import Agent
Create a simple agent
agent = Agent( name="myassistant", systemprompt="You are a helpful assistant." )
Chat with your agent
response = agent.chat("Hello, who are you?") print(response) ```
Adding Tools
```python import pixeltable as pxt from pixelagent.anthropic import Agent import yfinance as yf
Define a tool as a UDF
@pxt.udf def stock_price(ticker: str) -> dict: """Get stock information for a ticker symbol""" stock = yf.Ticker(ticker) return stock.info
Create agent with tool
agent = Agent( name="financialassistant", systemprompt="You are a financial analyst assistant.", tools=pxt.tools(stock_price) )
Use tool calling
result = agent.tool_call("What's the current price of NVDA?") print(result) ```
State management
```python import pixeltable as pxt
Agent memory is automatically persisted in tables
memory = pxt.gettable("myassistant.memory") conversations = memory.collect()
Access tool call history
toolslog = pxt.gettable("financialassistant.tools") toolhistory = tools_log.collect()
cusomatizable memory database
conversationalagent = Agent( name="conversationagent", systemprompt="Focus on remebering the conversation", nlatest_messages=14 ) ```
Custom Agentic Strategies
```python
ReAct pattern for step-by-step reasoning and planning
import re from datetime import datetime from pixelagent.openai import Agent import pixeltable as pxt
Define a tool
@pxt.udf def stock_info(ticker: str) -> dict: """Get stock information for analysis""" import yfinance as yf stock = yf.Ticker(ticker) return stock.info
ReAct system prompt with structured reasoning pattern
REACT_PROMPT = """ Today is {date}
IMPORTANT: You have {max_steps} maximum steps. You are on step {step}.
Follow this EXACT step-by-step reasoning and action pattern:
- THOUGHT: Think about what information you need to answer the question.
- ACTION: Either use a tool OR write "FINAL" if you're ready to give your final answer.
Available tools: {tools}
Always structure your response with these exact headings:
THOUGHT: [your reasoning] ACTION: [tool_name] OR simply write "FINAL" """
Helper function to extract sections from responses
def extractsection(text, sectionname): pattern = rf'{section_name}:?\s(.?)(?=\n\s*(?:THOUGHT|ACTION):|$)' match = re.search(pattern, text, re.DOTALL | re.IGNORECASE) return match.group(1).strip() if match else ""
Execute ReAct planning loop
def runreactloop(question, maxsteps=5): step = 1 while step <= maxsteps: # Dynamic system prompt with current step reactsystemprompt = REACTPROMPT.format( date=datetime.now().strftime("%Y-%m-%d"), tools=["stockinfo"], step=step, maxsteps=maxsteps, )
# Agent with updated system prompt
agent = Agent(
name="financial_planner",
system_prompt=react_system_prompt,
reset=False, # Maintain memory between steps
)
# Get agent's response for current step
response = agent.chat(question)
# Extract action to determine next step
action = extract_section(response, "ACTION")
# Check if agent is ready for final answer
if "FINAL" in action.upper():
break
# Call tool if needed
if "stock_info" in action.lower():
tool_agent = Agent(
name="financial_planner",
tools=pxt.tools(stock_info)
)
tool_agent.tool_call(question)
step += 1
# Generate final recommendation
return Agent(name="financial_planner").chat(question)
Run the planning loop
recommendation = runreactloop("Create an investment recommendation for AAPL") ```
