Struct ToolSchema 

pub struct ToolSchema {
    pub name: String,
    pub source: ToolSourceKind,
    pub description: String,
    pub parameters: Value,
    pub returns: Option<Value>,
    pub idempotent: bool,
    pub cache_ttl_secs: Option<u64>,
    pub rate_limit: Option<ToolRateLimit>,
}

Rich schema describing a tool’s interface and runtime configuration.

Carries everything the runtime needs: parameter validation via JSON Schema, idempotency hints, caching policy, rate limiting, and origin attribution.

Fields

name: String

source: ToolSourceKind

Origin classification surfaced by tools.list and execution events. Older serialized schemas default to caller-defined tools.

description: String

parameters: Value

JSON Schema for parameters (e.g. {"type": "object", "properties": {...}, "required": [...]})

returns: Option<Value>

JSON Schema for return value (optional)

idempotent: bool

Whether this tool is idempotent (safe to cache/retry)

cache_ttl_secs: Option<u64>

If set, results are cached with this TTL in seconds

rate_limit: Option<ToolRateLimit>

If set, rate limited to this many calls per interval
