Tools should be in which directory to tool registry?

[AstridRylan]

tutorials:
Craft functions or classes tailored to enable specific interactions with the external environment and place them in the metagpt/tools/libs directory.

But the directory should be in metagpt/tools/libs or miniconda3\envs\metagpt\Lib\site-packages\metagpt\tools\libs?

If it is placed in metagpt/tools/libs, importErr will appear.
Putting it in miniconda3\envs\metagpt\Lib\site-packages\metagpt\tools\libs is obviously unreasonable in a production environment.
