Extract the portable text fallback from a tool result

Works with an ellmer::ContentToolResult, an on_tool_result event, or a character value. Third-party UIs should display this value whenever they do not support the result's artifact schema/version/kind.

Usage

tool_result_value(result, default = "")

Arguments

result

An ellmer::ContentToolResult, on_tool_result event list, or character value.

default

Character fallback used when no value can be extracted.

Value

A character scalar.
