Struct ToolUsageSummary 

pub struct ToolUsageSummary {
    pub tool_name: String,
    pub invocations: u32,
    pub errors: u32,
}

Aggregated tool invocation statistics, grouped by tool name.

Extracted from session_messages rows with role = "tool_use" and role = "tool_result". The error count is derived by joining each tool_use to its matching tool_result and checking the is_error flag.

Fields

tool_name: String

The tool name (e.g. "MemorySearch", "VaultGet").

invocations: u32

Total number of times this tool was invoked.

errors: u32

How many of those invocations resulted in an error.
