An opinion piece argues that the largest cost associated with using AI models like Claude is not the model itself or the task, but rather the persistent instruction files that are loaded with every prompt. These context files, often referred to as CLAUDE.md, can grow over time with added rules, style guides, and edge cases, leading to recurring token costs for lines of text that are no longer relevant or even remembered by users. The author suggests a disciplined approach to managing these files, treating each line as a recurring cost and actively removing outdated information when new lines are added, which can lead to both cost savings and improved model performance.
