Ludwig's WRAP-UP
The phrase "claims to be able" is a common and grammatically correct construction used to report someone's assertion of their capability while subtly expressing doubt or skepticism.

When using this phrase, it's essential to be aware of its subtle implications and to use it judiciously to avoid conveying unnecessary cynicism. Alternative phrases like "is able to" or "has the capacity to" can be used for more neutral statements.
