Struct ToolSpanParams 

pub struct ToolSpanParams<'a> {
    pub tool_name: &'a str,
    pub tool_call_id: &'a str,
    pub display_name: &'a str,
    pub tier: Option<ToolTier>,
    pub kind: &'static str,
}

Available on crate feature otel only.

Inputs needed to open an execute_tool INTERNAL span.

Mirrors the attributes set by agent_loop::tool_execution::start_tool_span.

Fields

tool_name: &'a str

gen_ai.tool.name — the protocol tool name.

tool_call_id: &'a str

gen_ai.tool.call.id — the LLM-assigned call id.

display_name: &'a str

agent_sdk.tool.display_name; skipped when empty.

tier: Option<ToolTier>

agent_sdk.tool.tier; None when the tool is unknown to the registry (matches the in-process loop’s unknown-kind path, which omits the tier attribute).

kind: &'static str

agent_sdk.tool.kind — sync / async / listen / unknown.
