Struct PipelineTool 

pub struct PipelineTool { /* private fields */ }

The execute_pipeline tool that runs multi-step tool chains.

Implementations

impl PipelineTool

pub const NAME: &'static str = "execute_pipeline"

pub fn new(config: PipelineConfig, tools: Vec<Arc<dyn Tool>>) -> Self

pub fn with_access_policy( config: PipelineConfig, tools: Vec<Arc<dyn Tool>>, access_policy: Option<ToolAccessPolicy>, ) -> Self

Trait Implementations

impl Attributable for PipelineTool

fn role(&self) -> Role

fn alias(&self) -> &str

fn tool_provenance(&self) -> ToolProvenance

Classifies whether a tool implementation is first-party native code or an extension. The conservative default prevents a new wrapper from inheriting native presentation privileges accidentally.

impl Tool for PipelineTool

fn name(&self) -> &str

Tool name (used in LLM function calling)

fn description(&self) -> &str

Human-readable description

fn parameters_schema(&self) -> Value

JSON schema for parameters

fn execute<'life0, 'async_trait>( &'life0 self, args: Value, ) -> Pin<Box<dyn Future<Output = Result<ToolResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execute the tool with given arguments

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.

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.

fn invocation_triggers(&self) -> Vec<String>

Lowercase phrases that suggest an inbound message wants this tool — e.g. routing wording or configured destination names for a delivery tool. A pre-turn prefilter may scan the message against these and nudge the model to consider the tool; the tool itself is never called by the prefilter.

fn spec(&self) -> ToolSpec

Assemble this tool’s spec. The default recomposes it from parameters_schema() and allocates a fresh Arc per call, so tools with large stored schemas override it to hand out Arc::clone instead (see McpToolWrapper). Delegating wrappers around a dyn Tool MUST forward spec() to the inner tool — relying on this default silently reintroduces a per-iteration deep clone of the inner schema and breaks Arc identity for downstream sharing.
