Osprey Framework

🎉 Latest Release: v2026.6.2 - Open & self-hosted model support: run the agent on any OpenAI-protocol model as a configuration change, with a new model-capability benchmark; plus facility-timezone unification, ARIEL publishing fixes, and hardening

🚧 Early Access Release
This is an early access version of the Osprey Framework. While the core functionality is stable and ready for experimentation, documentation and APIs may still evolve. We welcome feedback and contributions!

A production-ready framework for deploying agentic AI in large-scale, safety-critical control system environments—particle accelerators, fusion experiments, beamlines, and complex scientific facilities.

📄 Research
This work was presented as a contributed oral presentation at ICALEPCS'25 and will be featured at the Machine Learning and the Physical Sciences Workshop at NeurIPS 2025.

🚀 Quick Start

# Install the framework as a standalone CLI tool (using uv, recommended)
uv tool install osprey-framework

# Create a minimal project to verify your setup
osprey build quickstart --preset hello-world
cd quickstart

# If API keys aren't already in your environment, copy and edit .env:
# cp .env.example .env

# Start a Claude Code agent session
claude

For a production project tailored to your detector, beamline, or accelerator
subsystem, install the guided osprey-build-interview skill and run it from Claude Code:

# Install the /osprey-build-interview skill into ~/.claude/skills/
uv run osprey skills install osprey-build-interview

Then start Claude Code in an empty directory and type /osprey-build-interview. The
skill walks you through a guided conversation, produces a build profile, and
osprey build profile.yml generates a ready-to-use project.

🧪 Testing

# Run unit tests (fast, no API keys required)
pytest tests/ --ignore=tests/e2e -v

# Run e2e tests (slow, requires API keys)
# ⚠️ IMPORTANT: Use 'pytest tests/e2e/' NOT 'pytest -m e2e'
pytest tests/e2e/ -v

See tests/e2e/README.md and the Contributing Guide for details.

Key Features

• Agent-Driven Orchestration - Skills, MCP tools, and explicit dependency declarations let the Osprey agent decompose operator requests into auditable steps with mandatory approval gates
• Control-System Safety - Pattern detection, PV boundary checking, and mandatory approval for hardware writes
• Protocol-Agnostic Integration - Seamless connection to EPICS, LabVIEW, Tango, and mock environments
• Scalable Capability Management - Dynamic classification prevents prompt explosion as toolsets grow
• Production-Proven - Deployed at major facilities including LBNL's Advanced Light Source accelerator
