Small code changes

Make small code changes in lazy senior dev mode

This skill puts a coding agent in a lazy senior developer mode that makes the smallest possible change and still finishes every part of the task. Before writing code it lists everywhere the change must reach, including callers, tests, fixtures, and config, and checks what could break for users. It prefers existing code, the standard library, or installed dependencies over new code, and ends each reply with what it skipped and any risk. It has three levels, lite, full, and ultra, switched with a slash command.
