On this tutorial, we discover how we design and run a full agentic AI orchestration pipeline powered by semantic routing, symbolic guardrails, and self-correction loops utilizing Gemini. We stroll by how we construction brokers, dispatch duties, implement constraints, and refine outputs utilizing a clear, modular structure. As we progress by every snippet, we see how the system intelligently chooses the appropriate agent, validates its output, and improves itself by iterative reflection. Take a look at the Full Codes right here.

@dataclass
class AgentMessage:
supply: str
goal: str
content material: str
metadata: dict
timestamp: float = time.time()We arrange our core setting by importing important libraries, defining the API key, and initializing the Gemini shopper. We additionally set up the AgentMessage construction, which acts because the shared communication format between brokers. Take a look at the Full Codes right here.

besides:
return "general_agent"We construct the cognitive layer utilizing Gemini, permitting us to generate each textual content and JSON outputs relying on the instruction. We additionally implement the semantic router, which analyzes queries and selects probably the most appropriate agent. Take a look at the Full Codes right here.
class Agent:
def __init__(self, title: str, instruction: str):
self.title = title

}
self.staff = {
"analyst_bot": Agent("analyst_bot", "You're a Information Analyst. output strict JSON."),
"creative_bot": Agent("creative_bot", "You're a Artistic Author."),
"coder_bot": Agent("coder_bot", "You're a Python Professional. Return solely code.")
}
self.router = SemanticRouter(self.agents_info)We assemble the employee brokers and the central orchestrator. Every agent receives a transparent position, analyst, artistic, or coder, and we configure the orchestrator to handle them. As we assessment this part, we see how we outline the agent ecosystem and put together it for clever activity delegation. Take a look at the Full Codes right here.

return consequence
besides Exception as e:
print(f" [System Error] {e}")
time.sleep(1)
print(" [Failed] Max retries reached or self-correction failed.")
return NoneWe implement symbolic guardrails and a self-correction loop to implement constraints like strict JSON or no Markdown. We run iterative refinement every time outputs violate necessities, permitting our brokers to repair their very own errors. Take a look at the Full Codes right here.
if __name__ == "__main__":
orchestrator = Orchestrator()
orchestrator.run_task(
"Evaluate the GDP of France and Germany in 2023.",
constraint="json_only"
)
orchestrator.run_task(
"Write a Python operate for Fibonacci numbers.",
constraint="no_markdown"
)We execute two full situations, showcasing routing, agent execution, and constraint validation in motion. We run a JSON-enforced analytical activity and a coding activity with Markdown restrictions to look at the reflexive conduct.
In conclusion, we now see how a number of elements, routing, employee brokers, guardrails, and self-correction, come collectively to create a dependable and clever agentic system. We witness how every half contributes to sturdy activity execution, guaranteeing that outputs stay correct, aligned, and constraint-aware. As we replicate on the structure, we acknowledge how simply we will increase it with new brokers, richer constraints, or extra superior reasoning methods.
