Handling Interrupt and Context-Aware Resume in Agent Streaming: One Task One Session, Handle Truncated Tool Calls
dotey · x · 2026-08-01
In an interview, the question was how to implement manual interruption and context-aware resume during agent streaming output. Key points:
- One Task One Session: User clicking Stop only interrupts the current run, not the whole conversation. Save the current context to the corresponding sessionId on stop, and load it back on resume.
- Handle truncated tool calls: If interruption occurs after toolcall is generated but before toolresult returns, the message chain is incomplete. Continuing directly may cause errors. Add a recovery result to make the context valid.
Core idea: Stop halts the output, not the task's memory. The author has applied this to the Stella project.
