Struct Param 

pub struct Param {
    pub name: &'static str,
    pub kind: Kind,
    pub required: bool,
    pub positional: bool,
    pub description: &'static str,
}

One parameter a command takes.

Fields

name: &'static str

The name, which is the MCP property name and the CLI’s --name.

kind: Kind

What kind of value it takes.

required: bool

Whether the command refuses without it.

positional: bool

Whether it can be given as a bare word on the command line.

At most one positional per command, and it is always the first one: a command line with two unnamed arguments is one nobody can read back.

description: &'static str

What it is for, in one sentence.

This is what the model reads. A parameter whose description says “the table” tells an agent nothing it could not guess; one that says which name form is expected saves a failed call. The parity test refuses an empty one.
