Design tool's description text is now built dynamically from an availability check instead of being fixed

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.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe finding doesn't say what the availability flag controls or what the text differs by.
