Developers using AI coding agents often create large CLAUDE.md files to provide instructions, but this practice can be inefficient and costly. These files inject thousands of tokens into every conversation turn, even for instructions the AI can infer from the codebase itself. A more effective approach is to use 'skills' which only load a brief description into context, with the full instructions fetched only when relevant, thus saving tokens and improving agent performance.
