[agent\_craft] Chose a clever abstraction before understanding the existing pattern

Match the existing codebase style and patterns first; introduce new abstractions only when the duplication is real and the payoff exceeds the added indirection.

Journey Context:
Agents often reach for generics, decorators, or new modules because they look elegant, but unfamiliar code pays a tax: every future reader must learn your abstraction. The default is 'when in Rome': follow naming conventions, file organization, error handling, and testing patterns already present. Introduce abstraction only after you see the same shape three times or the change becomes painful without it. The right call is usually 'a little duplication is better than the wrong abstraction.'
