Inline assistant called `{REWRITE_SECTION_TOOL_NAME}` after

Error message

Inline assistant called `{REWRITE_SECTION_TOOL_NAME}` after `{FAILURE_MESSAGE_TOOL_NAME}`

What it means

Raised by the inline assistant's tool-use processor when the model calls rewrite_section after it already invoked the failure_message tool. Once the model has declared failure for this assist, no further rewrite is accepted; the offending input is the out-of-order REWRITE_SECTION tool call arriving after FAILURE_MESSAGE in the completion stream.

Solutions

1. Retry the inline assist to get a coherent single-tool response
2. Simplify the requested edit so the model does not mix failure reporting with rewriting
