Problem
When the agent attempts a large write operation (e.g., replacing ~250 lines in a single Write/Edit tool call), the API response gets terminated mid-generation, resulting in:
The session shows a "继续" (Continue) button, suggesting the response was cut off.
Context from screenshot
- Agent was working on rewriting Phase 2-7 of a SKILL.md file (lines 680-926, ~246 lines)
- Multiple subagents had completed and returned
- The agent attempted to replace the entire section in one shot
- The API call was terminated before the write completed
Likely Cause
The API response exceeded the maximum output token limit or hit a timeout while generating the large content block for the Write/Edit tool call. This is a known limitation when the model tries to output very large code blocks in a single response.
Expected Behavior
- The agent should either chunk large writes into smaller operations
- Or the system should handle the termination more gracefully with a retry mechanism
- The error message could be more descriptive (e.g., "Response too long, try breaking into smaller operations")
Environment
- Web UI session with Codex/Claude
- YOLO permission mode
- Large file editing scenario
