}Required Methods§
Sourcefn description(&self) -> &str
fn description(&self) -> &str
Human-readable description
Sourcefn parameters_schema(&self) -> Value
fn parameters_schema(&self) -> Value
JSON schema for parameters
Provided Methods§
Sourcefn output_schema(&self) -> Option<Value>
fn output_schema(&self) -> Option<Value>
JSON schema describing the structured output this tool attaches to
ToolOutput::data, when it declares one. None means the tool
emits display text only; authoring surfaces fall back to
sample-derived shapes from captured runs.
Sourcefn param_domains(&self) -> Vec<(&'static str, OptionDomain)>
fn param_domains(&self) -> Vec<(&'static str, OptionDomain)>
Option domains for parameters whose value sets live in runtime config rather than the static schema (channel refs, peer targets, …). Surfaces resolve these through the runtime to render real selectable choices. Default: no domain-typed parameters.
