ToolFinished

Fields

id: String

output: Vec<String>

status: ToolStatus

write_result: Option<WriteResult>

Structured write result if this was a file-write tool, else None.

shell_result: Option<Box<ProcessResult>>

Structured shell result if this was a run_shell tool, else None. Boxed to avoid a large enum variant (ProcessResult carries multiple Vec<String> values).
