- [ ] 👋 I may be able to implement this feature request
- [ ] ⚠️ This feature might incur a breaking change

The issue names no files, tests, or entry points. Start by locating the CLI flow that displays and selects functions, then define how search should narrow the 48-function list; done means functions can be selected faster through name search without breaking existing selection.
