Struct Hints 

pub struct Hints {
    pub read_only: bool,
    pub destructive: bool,
    pub idempotent: bool,
    pub open_world: bool,
}

What a caller may assume about a call before making it: the four facts MCP names tool annotations, held once on the model so that no projection states its own.

Classified by ExecutionPolicy::hints, never declared.

use majordomus_cli::capability::{CapabilityKind, ExecutionPolicy, Hints};
let read: Hints = ExecutionPolicy::classify(CapabilityKind::Query).hints();
assert_eq!(
    serde_json::to_value(read).unwrap(),
    serde_json::json!({ "read_only": true, "destructive": false, "idempotent": true, "open_world": false })
);

Fields

read_only: bool

The call changes nothing, anywhere.

destructive: bool

The call may overwrite or remove something that outlives this process.

idempotent: bool

A second identical call changes nothing the first did not.

open_world: bool

The call reaches beyond this machine. No handler of this executable does: observing the forge and talking to an advisor are commands a person runs, not capabilities.

Trait Implementations

impl Clone for Hints

fn clone(&self) -> Hints

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Hints

impl Debug for Hints

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Hints

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Hints

impl JsonSchema for Hints

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Hints

fn eq(&self, other: &Hints) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Hints

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
