Under the hood
One built-in tool now gets a special-case exception in the built-in vs MCP classification logic
What
The internal logic that classifies a tool as MCP (Model Context Protocol), built-in, or undefined now takes an extra input and adds a special case: if a tool's name matches one particular built-in tool and none of the extra input matches a specific identifier, it's classified as "built-in" even in a situation where it would otherwise have failed the general built-in check.
Why
This fixes a case where that particular tool could be misclassified, ensuring it's consistently recognized as a built-in tool.

The writer flagged doubt
The finding doesn't say which specific tool this exception applies to.
