Enum ToolTier 

#[non_exhaustive]
pub enum ToolTier {
    Core,
    Host,
    Optional,
}

Where a built-in tool sits under the proposed runtime composition contract.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Core

The retained core set.

Host

Host-coupled: the runtime keeps constructing it, because it needs a runtime handle that ToolRequest would not carry, because the runtime keys execution behavior on its name, or by a recorded judgment call.

Optional

Optional: constructible from ToolRequest alone.
