会话自救与预防：拦截空 tool_use.name，避免“全会话持续报错”
场景：历史里写入空的 tool_use.name 后，后续消息全部被 LLM 请求校验拒绝。前置：可访问会话历史并执行会话重置。步骤：先识别错误签名，再新建会话隔离影响，最后在工具调用修复逻辑中增加 name 非空校验。关键点：repair 不能只校验 input。验证：同模型连续工具调用不再触发该错误。风险：仅靠手工 /new 会反复复发。

Prerequisites
- You can identify failed sessions and inspect error text from logs/history.
- You can apply a fix/guard in tool-call sanitation path or upgrade to patched release.
Steps
- Detect the signature error: `tool_use.name: String should have at least 1 character`.
- Mitigate user impact immediately by moving to a new session for ongoing work.
- Add/enable validation to reject or repair malformed tool blocks when `name` is empty.
- Replay multi-tool conversations to ensure malformed blocks no longer persist.
Commands
openclaw gateway statusopenclaw gateway restartVerify
Repeated tool-heavy conversations no longer fail with empty-name validation errors.
Caveats
- Session reset (`/new`) is temporary mitigation, not root-cause fix.
- Exact sanitizer hook location differs by version/provider adapter（需验证）.
