我在项目上下文文件中实际使用的内容

Every AI coding tool has its own context file, such as Cursor with .cursorrules and .mdc files, Claude Code with CLAUDE.md, and Copilot with .github/copilot-instructions.md. These files primarily serve to instruct the AI on how to write code. However, most guides stop at the format level, failing to delve into which rules the AI actually follows and which ones it quietly ignores. After several weeks of testing, specifically with Cursor's .mdc format, various compliance issues were identified, some of which were obvious while others were not, providing important insights into understanding AI behavior.
