claude-code - 💡(How to fix) Fix [BUG] Model silently stops mid-task after tool call without generating follow-up [1 comments, 2 participants]

Claude Code silently stops execution mid-task after a tool call (typically an Edit) without generating any follow-up text or invoking the next tool. The conversation appears to hang - no output, no error, no indication that work has stopped. The user has to manually prompt to resume. The turn ends after the tool result with no output. No error, no permission prompt, nothing. Claude just froze.

Error Messages/Logs

TL;DR

The issue can be mitigated by adjusting the task structure to avoid sequential Edit tool calls or investigating the Anthropic API's handling of long-running tasks.

Guidance

• Investigate if the Anthropic API has limitations or specific requirements for handling sequential tool calls, especially for tasks involving multiple file edits.
• Consider restructuring the task to minimize sequential Edit tool calls, potentially by batching edits or using alternative tools that can handle multiple operations in a single call.
• Verify if the issue persists across different models or context sizes to determine if it's specific to the claude-opus-4-6 model or a more general problem.
• Check for any updates or known issues in the Claude Code VS Code extension that might address silent task termination.

Example

No specific code example can be provided without more details on the task structure and tool calls, but adjusting the sequence or nature of tool calls could look like reordering tasks or using a different tool that can handle multiple edits at once.

Notes

The root cause of the silent termination is unclear without more information on the Anthropic API's behavior or the specific task structure. The issue might be related to how the API handles long-running tasks or sequential operations.

Recommendation

Apply workaround: Restructure tasks to minimize sequential Edit tool calls, as this approach can potentially mitigate the issue without requiring updates to the Claude Code extension or Anthropic API.
