Struct SkillTool 

pub struct SkillTool { /* private fields */ }

The skill tool. It is registered on StaticToolRegistry and shared across sessions of the owning AgentCore via process_tools (it is not a process-global singleton—a single process may host multiple AgentCore instances, each with its own skill index).

Implementations

impl SkillTool

pub fn new(skills: Arc<BTreeMap<String, SkillEntry>>) -> Self

Constructs a skill tool. When skills is empty, callers should not register this tool (the schema’s name enum will be empty, so it will always fail) — see Self::has_skills.

pub fn has_skills(skills: &BTreeMap<String, SkillEntry>) -> bool

Whether any skills were discovered. The assembler uses this to decide whether to register this tool.

Trait Implementations

impl Tool for SkillTool

fn schema(&self) -> &ToolSchema

Tool metadata. Returns a reference to avoid allocating on every call.

fn safety_hint(&self, _args: &Value) -> SafetyClass

Provides a safety-level hint to the sandbox policy without actually executing the tool.

fn describe<'a>( &'a self, args: &'a Value, _ctx: ToolContext<'a>, ) -> BoxFuture<'a, ToolCallDescription>

Generates a “self-description” before execution, for display to the ACP client.

fn execute(&self, args: Value, _ctx: ToolContext<'_>) -> ToolStream

Initiates a tool call and returns an event stream.
