Memory bank for smolagents

[luiztauffer]

How could we implement something similar to cline’s memory bank in smolagents? The goal is to have a source of long term memory for longer and complex tasks, which will help agents:

• keep the end goals of the project always within the working context
• keep tab of the steps already successfully completed along the way, and avoid unnecessary changes or repeated tasks, something I noticed happening for (poorly) managed agents
• avoid hallucination along the way
• provide a documented and organized feedback to the human user
• provide a common source of shared progress and results for multiple, parallel agents

I guess we could simply have an optional addition to the agents system prompt with similar instructions as that reference, but given that smolagents is a more general tool than cline, I was wondering if anyone has had any experience in implementing a similar feature for smolagents, or if anyone would like to discuss strategies for that.

Some ideas:

• we could standardize the long-term memory files names and relative path
• we could have a standard MemoryBankTool which the agents could rely on to read or update those files
