CLI-First deterministic multi-agent orchestration library

DeterminAgent

CLI-First Deterministic Multi-Agent Orchestration Library

Orchestrate powerful AI workflows at zero extra cost. DeterminAgent controls multiple AI CLI tools (Claude Code, GH Copilot, Gemini CLI, OpenAI Codex) using LangGraph to create deterministic pipelines powered by your existing flat-rate subscriptions.

🚀 First Contact

DeterminAgent is a Python library for developers who want to build complex, multi-agent systems without paying for expensive per-token API calls. By wrapping the CLI tools you already pay for, DeterminAgent allows you to build production-grade workflows for $0 in variable costs.

Key Features

• Library-Only: Full control in pure Python. No proprietary YAML DSL.
• Subscription Arbitrage: Uses your flat-rate CLI subscriptions.
• Deterministic: Powered by LangGraph state machines.
• Zero-Latency: Controls local tools via subprocess.

From Source

For the latest development version or to contribute:

# Clone the repository
git clone https://github.com/determinagent/determinagent.git
cd determinagent

# Install dependencies and set up environment
poetry install

# Verify installation
poetry run python -c "import determinagent; print(determinagent.__version__)"

Prerequisites

• Python 3.10+
• At least one supported AI CLI tool installed and authenticated:
  • Claude Code (claude)
  • GitHub Copilot CLI (gh copilot)
  • Gemini CLI (gemini)
  • OpenAI Codex (codex)

⚡ Quick Start

Library Usage

from determinagent import UnifiedAgent, SessionManager

# Create a deterministic agent
writer = UnifiedAgent(
    provider="claude",
    model="balanced",
    role="Technical Blogger",
    session=SessionManager("claude")
)

# Send a prompt - zero per-token cost!
response = writer.send("Explain LangGraph in 3 sentences.")
print(response)

Template Flows

Don't start from scratch. Use our pre-built Python templates in the flows/ directory:

• flows/blog/: Complete Writer → Editor → Reviewer workflow with human review.

To run the blog flow:

python flows/blog/main.py "My Blog Topic" --writer claude --editor copilot

🛠️ Troubleshooting

Common Issues

1. ProviderNotAvailable: CLI command 'claude' not found

   • Ensure the tool is installed and available in your $PATH.
   • Run claude --version manually to verify.

2. Authentication Errors

   • DeterminAgent uses your local sessions. Ensure you are logged in to the CLI tool (e.g., gh auth status or claude login).

3. Subprocess Timeouts

   • Some agents (like Writer) can take a few minutes for long content. Ensure your environment doesn't kill long-running processes.

Debug Mode

Set LOG_LEVEL=DEBUG to see the full subprocess commands and raw output.
