The shared blackboard pattern is back and it's solving multi-agent context loss

说明与用途

黑板模式有效缓解多代理LLM系统中的上下文丢失，提高准确性和效率，但需要范围投影和治理。

问题

Agents in a multi‑agent system were unable to see shared context, causing repetitive loops and loss of information across handoffs.

结果

The blackboard pattern improved information fidelity at the coder stage by 62%, correct file targeting by 27.5 percentage points, and achieved 100% ledger accuracy versus 0% in a production system, with 26× lower latency and 29× lower token consumption.

工作流

• 1. Agents publish messages with optional references to prior messages.
• 2. Agents search the board by content, receiving at most k relevant messages.
• 3. Agents visit specific messages by address.
• 4. A Supervisor LLM orchestrates agent turns based on board state.
• 5. Governance policies enforce scoped retrieval, temporal supersession, provenance tracking, and policy‑governed propagation.

证据

The shared blackboard wasn't shared.
