Development Experience

Descriptions are crucial. When describing parameters, you should inform the client how to use the output of one tool to modify the input format of another tool.

For example, the output of searchPackage includes the names of sub - packages but not the package name. Therefore, if you want the LLM to use getPackageInfo to obtain information about a sub - package, I wrote the following description for the packageName parameter:

The name of the package to search for. If you have previously used searchPackages and the user wishes to obtain information about a sub - package, you should combine them. For example, when the user queries mcp, it returns packageName: github.com/mark3labs/mcp - go/mcp and a sub - package client. Then, if the user wishes to obtain information about the client, you should set packageName to github.com/mark3labs/mcp - go/mcp/client instead of client.

If you use this detailed description, the LLM will tell you the names of some sub - packages. You can directly tell it which package's information to obtain, or which package and its sub - packages' information to obtain, and then it will combine them and call getPackageInfo to retrieve the information.

Therefore, perhaps we should allow users to configure this description to make the tool more useful and efficient.
