I use a common README_AI.md file, and use CLAUDE.md and AGENTS.md to direct the agent to that common file. From README_AI.md, I make specific references to skills. This works pretty well - it's become pretty rare that the agent behaves in a way contrary to my instructions. More info on my approach here: https://www.appsoftware.com/blog/a-centralised-approach-to-a... ... There was a post on here a couple of days ago referring to a paper that said that the AGENTS file alone worked better than agent skills, but a single agents file doesn't scale. For me, a combination where I use a brief reference to the skill in the main agents file seems like the best approach.
