Why does the execution of `/speckit.implement` in the GitHub spec-kit using gpt5.1 and gemini3-pro always break?

[lrshu]

Why does the /speckit.implement function of the GitHub spec-kit, using gpt5.1 and gemini3-pro, always crash during execution?

The preceding steps are normal, but various crashes occur during the implement step, including:

1. After completing several tasks, it prompts for permission to continue with the test and then for permission to proceed.

2. The output fails to allow further operation.

After many such crashes, it becomes very difficult to use.
