In this tutorial, we dive into building an advanced AI agent system based on the SAGE framework, Self-Adaptive Goal-oriented Execution, using Google’s Gemini API. We walk through each core component of the framework: Self-Assessment, Adaptive Planning, Goal-oriented Execution, and Experience Integration. By combining these, we aim to create an intelligent, self-improving agent that can deconstruct a high-level goal, plan its steps, execute tasks methodically, and learn from its outcomes. This hands-on walkthrough helps us understand the underlying architecture and also demonstrates how to orchestrate complex decision-making using real-time AI generation. Check out the FULL CODES here.

class TaskStatus(Enum):
PENDING = "pending"
IN_PROGRESS = "in_progress"

FAILED = "failed"We start by importing the necessary libraries, including google.generativeai for interacting with the Gemini model, and Python modules like json, time, and dataclasses for task management. We define a TaskStatus enum to help us track the progress of each task as pending, in progress, completed, or failed. Check out the FULL CODES here.

We wrap up the tutorial by initializing the SAGEAgent with our Gemini API key and defining a sample goal on sustainable urban gardening. We then execute the full SAGE cycle and print a detailed summary, including progress scores, task counts, and memory insights, allowing us to evaluate how effectively our agent performed across iterations.
In conclusion, we successfully implemented and ran a complete SAGE cycle with our Gemini-powered agent. We observe how the system assesses its progress, dynamically generates actionable tasks, executes them with precision, and refines its strategy through learned experience. This modular design empowers us to extend the framework further for more complex, multi-agent environments or domain-specific applications.
