Date: 2026-01-08 00:00 Summary: Added a rule to exclude AI trailing questions from development logs.

[question] 修改默认规则,增加规则：不要记录最后ai的提问这些没有意义的内容，并更新跟则

[try to solve] Updated .github/copilot-instructions.md: under default agent behavior, added an “Exclusions” rule so logs omit AI trailing questions/clarifications and only record the user question and the final answer.
