Yep, basically this. In the end it helps having the mental model that (almost) everything related to agents is just a way to send the upstream LLM a better and more specific context for the task you need to solve at that specific time. i.e Claude Code "skills" are simply a markdown file in a subdirectory with a specific name that translates to a `/SKILL_NAME` command in Claude and a prompt that is injected each time that skill is mentioned or Claude thinks it needs to use, so it doesn't forget the specific way you want to handle that specific task.
