Agent V2: Autonomous Agent Capability

[Peteredwardj]

This PR introduces Agent V2, that brings autonomous agent capabilities using LangChain and LangGraph. With this new mode, agents can plan their own tasks, execute chains of actions, and evaluate their own decisions, making them more powerful and agentic.

This work was done by @MaxHuber888 and me.

🔑 Key Terms

• Autonomous Mode: The new agentic mode where the agent follows a structured workflow graph, enabling task planning, execution, and self-evaluation.
• Legacy Mode: The previous/default mode where the agent randomly selects tasks in each loop.

🚨 Note:

• Autonomous mode is now the default implementation in agent.py
• Legacy mode has been moved to legacy-agent.py

Autonomous Mode
A new structured workflow that allows the agent to:
✅ Plan and execute tasks independently, rather than randomly selecting actions.
✅ Use any connection as a LangChain tool, simplifying integrations and reducing manual work.
✅ Perform multi-step actions in natural language, e.g.,

"Tweet the contract address of Zerebro on Solana and include the price."

Legacy mode remains available, but existing agent config files must be updated to the new format for compatibility. Use the new command : migrate to easily migrate your agent json to the new format.

Enhancements & Changes

1. Streamlined agent configuration files
   Check auto-example and legacy-example for new formats.
2. Connections as Tools
   A new wrapper in BaseConnection converts connections into LangChain tools, making them readily available for the agent.
3. Add command migrate to migrate your old agent configs to the new format
4. Add command query to give you the ability to feed single task to the autonomous agent quickly. Useful for testing, or just accomplishing single tasks (with no loop)

Notes & Considerations:

1. Autonomous mode is still in early testing , and contributions are welcome!
2. Use the new command migrate to easily migrate your agent json to the new format.

i couldnt get it to work with any other connections than twitter. when i tried doing onchain solana actions it always brought in twitter actions
