Enum PrimitiveKind 

pub enum PrimitiveKind {
    Tool,
    Resource,
    ResourceTemplate,
    Prompt,
}

Which list a primitive belongs to.

The four lists are separate on the wire (tools/list, resources/list, resources/templates/list, prompts/list) and they are notified on separately, so the distinction is load-bearing rather than cosmetic: a tool being added must not make a session’s prompt list appear to have changed.

Ord and PartialOrd are derived from the same declaration order, and PrimitiveKind::ORDERING_AGREES is the test that says so. The declaration order is a display order chosen once — tools, then resources, then templates, then prompts, matching the order the specification introduces them — and it is not the order any peer observes, because Snapshot keeps each list in registration order and this only orders the kinds when a change set is rendered.

Variants

Tool

tools/list, tools/call.

Resource

resources/list, resources/read.

ResourceTemplate

resources/templates/list.

Prompt

prompts/list, prompts/get.

Implementations

impl PrimitiveKind

pub const ALL: [Self; 4]

Every kind, in declaration order.

pub const fn as_str(self) -> &'static str

The name used in a log line and in a change set.

pub const fn feature(self) -> Feature

The feature a session needs before it may list this kind.

So the listing methods’ gates are written once. A table here rather than at each call site is the point: resources/list and resources/templates/list are separate methods in the spec, and a second place naming which requires which feature is a second place to forget it.

ResourceTemplate maps to Feature::Resources, not to a feature of its own, because the specification’s resources capability covers templates too. A peer that can list resources can list their templates; a separate feature would gate the two independently and let a session hold the odd combination the spec has no way to express.
