🧠 Hermes Agent Assistant — A Modular AI Agent System with Planner, Executor & Memory

Hermes Agent Challenge Submission: Write About Hermes Agent

🚀 What I Built

I built Hermes Agent Assistant, a lightweight agentic AI system designed to demonstrate how modern AI agents can be structured using a modular architecture instead of a simple, single-prompt response model.

The system takes an abstract user task, breaks it down into structured steps using a dedicated planner, executes those steps sequentially via an execution engine, utilizes targeted tools, and stores the interaction context in a persistent memory system.

⚙️ Why I Built This

Most AI applications today are simple wrappers around LLMs that rely on a single input-output loop. I wanted to understand and demonstrate how production-grade, autonomous agent systems operate internally. Specifically, I wanted to explore how:

  • Planning can be decoupled from execution to allow for complex error handling and multi-step reasoning.
  • Tools can be dynamically integrated into an agent's reasoning loop.
  • State and memory can persist across tasks to enable true contextual continuity.

Hermes Agent is my architecture simulation built to solve this problem in a highly accessible, lightweight, and scalable format.

🧠 System Architecture & Workflow

The codebase is split cleanly into four autonomous components that mirror real-world AI agent meshes:

💡 What Makes It Different

Unlike traditional, rigid APIs or simple conversational chatbots, Hermes Agent:

  • Thinks in Workflows: It establishes an internal chain-of-thought lifecycle before executing anything.
  • Separates Reasoning from Action: Slicing the Planner from the Executor prevents cascading generation failures.
  • Is Highly Extensible: New tools and custom utility logic can be dropped into the system without breaking core routing.
  • Maintains Context Persistence: The custom memory module ensures state history is preserved between network calls.

🧰 Tech Stack

  • Core Language: Python 3.10+
  • Web Framework: FastAPI (Asynchronous Server Gateway Interface)
  • Production Server: Uvicorn
  • Memory Layer: Volatile-to-Persistent JSON state manager
  • Architecture Pattern: Modular Agentic Workflow Design

🔮 Future Improvements & Roadmap

  • 🤖 Real Foundation LLM Integration: Swapping out simulated logic for live OpenAI, Anthropic, or local open-source Ollama completion hooks.
  • 🗄️ Vector Database Memory Upgrade: Transitioning flatfile storage over to a proper semantic vector indexing framework (FAISS / ChromaDB) for semantic chunk lookups.
  • 🤝 Multi-Agent Orchestration: Upgrading the workflow to host distinct Planner, Executor, and Critic agents working collaboratively with separate system prompts.
  • ⚡ Live Server-Sent Events (SSE): Integrating real-time execution streaming so client frontends can observe the agent's thought process step-by-step.
