# .agents（多语言）
|
||
|
||
本目录用于存放仓库级/语言级的代理规则集。
|
||
|
||
建议约定：
|
||
|
||
- `.agents/tsl/`：TSL 相关规则集（由 `sync_standards.*` 同步；适用于 `.tsl`/`.tsf`）
|
||
- `.agents/cpp/`、`.agents/python/` 等：其他语言的规则集（按需增加）
|
||
|
||
规则发生冲突时，建议以“更靠近代码的目录规则更具体”为准。
|
||
|
||
入口建议从：
|
||
|
||
- `.agents/tsl/index.md`（TSL 规则集入口）
|
||
- `docs/standards/tsl/docs/tsl/`（TSL 人类开发规范快照，推荐 subtree/vendoring 到该路径）
