You can have a look at Langroid -- it's an agent-oriented LLM programming framework from CMU/UW-Madison researchers. We started building it in Apr 2023 out of frustration with the bloat of then-existing libs.
In langroid you set up a ChatAgent class which encapsulates an LLM-interface plus any state you'd like. There's a Task class that wraps an Agent and allows inter-agent communication and tool-handling. We have devs who've found our framework easy to understand and extend for their purposes, and some companies are using it in production (some have endorsed us publicly). A quick tour gives a flavor of Langroid: https://langroid.github.io/langroid/tutorials/langroid-tour/
