Agentbx: A Redis-Based Crystallographic Agent System

[][license]

Overview

Agentbx is a Python-based system for managing crystallographic & electron microscopy computing using a Redis-backed agent architecture. It is designed for modular, distributed, and AI-integrated scientific computing, with a focus on clear separation of concerns and robust, persistent data handling.

Key Concepts & Architecture

Modular Separation: Agents, Clients, and Processors

• Agents (src/agentbx/core/agents/):
  • Long-running services that listen to Redis streams for requests (e.g., geometry calculation, security management).
  • Example: AsyncGeometryAgent processes geometry calculation requests and returns results via Redis.
• Clients (src/agentbx/core/clients/):
  • Optimizers and user-facing modules that submit requests to agents and update bundles (e.g., coordinate, B-factor, solvent optimizers).
  • Follow PyTorch conventions for optimization (separate backward/step logic).
• Processors (src/agentbx/processors/):
  • Stateless, single-responsibility modules for core scientific calculations (e.g., geometry, gradients, structure factors).

Redis as the Central Nervous System

• Bundles: All data (atomic models, gradients, results) are stored as versioned bundles in Redis.
• Streams: Agents and clients communicate via Redis streams for robust, asynchronous, and distributed operation.

No Internal Workflow Engine

• Workflow orchestration is now externalized: Instead of internal workflow management, users are encouraged to use modern orchestration tools like Prefect or LangGraph to coordinate multi-step pipelines and distributed jobs.
• Agentbx provides the building blocks (agents, clients, processors, bundles) for these workflows, but does not enforce or manage workflow logic internally.

Directory Structure

src/agentbx/
  core/
    agents/      # Agent services (e.g., AsyncGeometryAgent, AgentSecurityManager)
    clients/     # Optimizers and user-facing modules (e.g., CoordinateOptimizer, BFactorOptimizer)
    processors/  # Stateless scientific processors (e.g., geometry, gradients)
    ...          # Redis manager, bundle base, config, etc.

Example: Multi-Process Usage

1. Start an Agent (in one shell):

   python -m agentbx.core.agents.async_geometry_agent
   # or use the provided example script
   

2. Run a Client Optimizer (in another shell):

   python examples/optimization_clients_example.py
   # or your own script using CoordinateOptimizer, BFactorOptimizer, etc.
   

3. Monitor Redis:
   • All communication and data flow through Redis, enabling robust, distributed, and restartable computation.

Integration with AI and External Orchestration

• AI Models: Easily integrate PyTorch/TensorFlow models as clients or processors.
• Orchestration: Use Prefect, LangGraph, or similar tools to build complex, multi-step scientific workflows using Agentbx as the computational backend.

Features

• Modular, single-responsibility agents and clients
• Persistent, versioned data bundles in Redis
• Stateless, testable processors for core scientific logic
• Seamless AI integration
• No internal workflow engine: bring your own orchestration
• Robust multi-process/multi-shell operation

Requirements

• Python 3.10+
• Redis
• CCTBX
• Pydantic
• Click
• Poetry
• (Optional) PyTorch/TensorFlow for AI integration

Installation

You can install Agentbx via [pip] from [PyPI]:

$ pip install agentbx

Or install with Redis support:

$ pip install agentbx[redis-agents]

Publishing to PyPI

To publish a new version to PyPI:

1. Update the version using the sync script:

   python scripts/sync_version.py 1.0.4
   

2. Commit and push your changes.
3. Ensure all tests pass and the package builds successfully.
4. Publish to PyPI (requires credentials):

   poetry publish --build
   

Getting Started

• See examples/optimization_clients_example.py for a full demonstration of agent/client interaction and optimization.
• See whatsnext.txt for a running development log and next steps.
• For orchestration, see Prefect or LangGraph documentation for how to build workflows using Agentbx components.
