Report #75475
[frontier] How do I prevent agents from blocking during long-running tool executions?
Implement streaming tool execution—stream partial results from tools as they become available \(via SSE or WebSockets\), allowing the agent to process incremental output and even abort early if intermediate results indicate a wrong path.
Journey Context:
Synchronous tool calls block the agent loop, wasting time and context window on irrelevant results. Streaming enables 'thinking with tools' where the agent sees stdout/stderr in real-time and can correct course. Tradeoff: requires refactoring tools to support streaming and handling partial JSON parsing, but dramatically improves latency for long operations.
