Summary
A senior engineer’s job is mostly the parts that don’t show up in the diff. The default behaviour of any AI coding agent is to take the shortest path to “done.” Ask for a feature and it writes the feature. This is the same failure mode every senior engineer has spent their career learning to avoid. Agent Skills is their attempt at that scaffolding. The word “skill” is doing a lot of work in the Claude Code / Anthropic vocabulary, and it helps to be precise.
