前端多语言(i18n)添加规范

商家端(foodie-store)使用 vue-i18n，语言文件在 src/lang/ 下（zh.js、tw.js、en.js、vi.js）。

添加多语言 key 时必须注意：

先确认 key 所属的对象层级。 语言文件中有多层嵌套对象（如 foots:{}、cuxiao:{}、fenlei:{} 等），使用 $t('foots.XXX') 的 key 必须添加到 foots 对象内部，不能加到文件顶部或其它对象里。
找到该对象的最后一个属性（通过 grep 或阅读文件定位），在其后追加新 key，确保逗号正确（中间属性末尾要有逗号，最后一个属性无逗号）。
四个语言文件（zh.js、tw.js、en.js、vi.js）都要添加，缺一不可。

曾经犯的错误： 把 AddCategoryFirst 加到了文件第 141 行的公共区域，而 $t('foots.AddCategoryFirst') 是在 foots 对象（第 190+ 行）下查找，导致页面显示原始 key 而非翻译文本。

前端文件编辑注意事项

前端项目（foodie-store、foodie-admin-vue）的文件使用 CRLF 换行符（Windows 风格 \r\n）。使用编辑工具进行字符串替换时，由于换行符不匹配会导致 "String to replace not found" 错误。

正确做法： 编辑前端文件时，使用 Python 脚本（python << 'PYEOF'）通过 content.replace() 或行号操作来修改文件内容，避免换行符匹配问题。

Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.

Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.

1. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Before implementing:

State your assumptions explicitly. If uncertain, ask.
If multiple interpretations exist, present them - don't pick silently.
If a simpler approach exists, say so. Push back when warranted.
If something is unclear, stop. Name what's confusing. Ask.

2. Simplicity First

Minimum code that solves the problem. Nothing speculative.

No features beyond what was asked.
No abstractions for single-use code.
No "flexibility" or "configurability" that wasn't requested.
No error handling for impossible scenarios.
If you write 200 lines and it could be 50, rewrite it.

Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.

3. Surgical Changes

Touch only what you must. Clean up only your own mess.

When editing existing code:

Don't "improve" adjacent code, comments, or formatting.
Don't refactor things that aren't broken.
Match existing style, even if you'd do it differently.
If you notice unrelated dead code, mention it - don't delete it.

When your changes create orphans:

Remove imports/variables/functions that YOUR changes made unused.
Don't remove pre-existing dead code unless asked.

The test: Every changed line should trace directly to the user's request.

4. Goal-Driven Execution

Define success criteria. Loop until verified.

Transform tasks into verifiable goals:

"Add validation" → "Write tests for invalid inputs, then make them pass"
"Fix the bug" → "Write a test that reproduces it, then make it pass"
"Refactor X" → "Ensure tests pass before and after"

For multi-step tasks, state a brief plan:

1. [Step] → verify: [check]
2. [Step] → verify: [check]
3. [Step] → verify: [check]

Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.

These guidelines are working if: fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
