Struct DiagnosticEntry 

pub struct DiagnosticEntry {
    pub agent_id: Option<String>,
    pub details: McpDiagnosticDetails,
    pub level: DiagnosticSeverity,
    pub message: String,
    pub original_bytes: Option<i64>,
    pub source: DiagnosticEntrySource,
    pub timestamp: String,
    pub truncated: Option<bool>,
}

One retained session-scoped diagnostic record. Potentially content-bearing diagnostic data is opt-in and must not be exported automatically as telemetry.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

details: McpDiagnosticDetails

Typed MCP diagnostic detail.

level: DiagnosticSeverity

Severity of this emitted diagnostic record.

message: String

Human-readable diagnostic summary.

original_bytes: Option<i64>

Original byte count when a known-size message or data value was truncated.

source: DiagnosticEntrySource

Diagnostic source identifying the typed details payload.

timestamp: String
