Without it, a tool that sets `is_error=True` alongside structured output would silently come back looking successful after the strip [[1]](https://github.com/apache/superset/pull/43374). **Test coverage is thorough.** The four cases (`ToolError` flagged, unexpected exception flagged, success path untouched, flag survives stripping) cover the relevant branches cleanly. **One open question you've already flagged:** confirming the serialized `ToolResult(is_error=True)` doesn't trigger the same Claude.ai bridge encoding failure. Your reasoning — that it serializes to a plain dict with a boolean field, not as the exception object that caused the bridge failure — is sound and consistent with the [issue discussion](https://github.com/apache/superset/issues/43358), but a maintainer with access to that bridge should verify before merging. The field name correction (`is_error` vs `isError`) is also worth calling out, which you've already done — the issue discussion had a snippet with the wrong name that raises `TypeError` [[2]](https://github.com/apache/superset/issues/43358). <!-- Dosu Comment Footer --> --- [](https://app.dosu.dev/response-feedback?utm_source=github&utm_medium=pr-comment&utm_campaign=github-pr-badges&utm_content=feedback&utm_term=apache%2Fsuperset&message_id=27398f09-166c-4c45-97df-97fdeca64568) [](https://github.dosu.com/apache/superset?utm_source=github&utm_medium=pr-comment&utm_campaign=github-pr-badges&utm_content=ask-repo&utm_term=apache%2Fsuperset) [](https://app.dosu.dev/signup?referrer=openSource&source=github-footer&utm_source=github&utm_medium=pr-comment&utm_campaign=github-pr-badges&utm_content=add-team&utm_term=apache%2Fsuperset) -- This is an automated message from the Apache Git Service.
