playgent 0.1.1

SDK for tracking and testing OpenAI API calls

Playgent

Record and test your OpenAI agent sessions.

Installation

pip install playgent

Quick Start

Step 1: Instrument your agent to record sessions

import json
from typing import List
import dotenv
import os

dotenv.load_dotenv()

from playgent.openai import OpenAI  # Drop-in replacement for OpenAI
from playgent import record, session

client = OpenAI()  # Automatically tracks all OpenAI calls

# Your agent functions here
def add_to_todo_list(task: str) -> str:
    # ... your implementation
    pass

@record  # This decorator records the entire session
def infer(input_text: str, model: str = "gpt-4", tools_list: List = None):
    messages = [{"role": "user", "content": input_text}]

    # Your agent logic with OpenAI calls
    response = client.chat.completions.create(
        model=model,
        messages=messages,
        tools=tools_list
    )

    # Process response and handle tool calls...
    return response

# Use session context manager to auto-create sessions
with session() as sess:
    result = infer("Add 'buy milk' to my todo list")

Step 2: Run tests via replay

After annotating sessions with expected outcomes on the Playgent dashboard:

from playgent import replay_test, evaluate
from example_agent import infer

# Test using a recorded session ID
test_case_id = "6996b53a-1ebf-403a-8770-10ed001391c3"

with replay_test(test_case_id) as (session_id, endpoint_events):
    for event in endpoint_events:
        infer(**event.arguments)
    result = evaluate(test_case_id, session_id)

That's it! Two steps:

1. Instrument - Add @record decorator and use playgent.openai.OpenAI
2. Test - Replay annotated sessions and evaluate results

Environment Setup

Create a .env file:

PLAYGENT_API_KEY=your-playgent-api-key
OPENAI_API_KEY=your-openai-api-key
