Agent Aware Message History Management With Role Based Filtering

via “agent-aware message history management with role-based filtering”

OpenAI's experimental multi-agent orchestration framework.

Unique: Message history is a simple list of dicts passed by reference, allowing callers to inspect, modify, or persist it directly without API abstractions; tool results are formatted as 'tool' role messages that the LLM natively understands, not wrapped in custom structures.

vs others: More transparent than Assistants API (which hides message history) and simpler than LangChain's BaseMemory because it's just a Python list that callers fully control.
