Unclear The finding doesn't say what the availability flag controls or what the text differs by.

What

The description and prompt text for the Design tool and the ClaudeDesign tool no longer return a fixed block of text. Both now generate their text by calling a formatting function that takes an availability flag as an argument.

Why

This means the text shown for these tools can now vary depending on whether the relevant feature is available, rather than always reading the same regardless of context.
