Struct TelemetryRecord 

pub struct TelemetryRecord {

    pub ts: u64,
    pub request_id: Option<String>,
    pub msg_id: Option<String>,
    pub model: String,
    pub attempt: u32,

    pub cache_diag: Option<CacheDiagRecord>,

    pub keepwarm: bool,
    pub worker: bool,
}

One JSONL record per API call.

Fields

ts: u64

Unix epoch milliseconds at request completion.

request_id: Option<String>

msg_id: Option<String>

Anthropic message id (msg_...) from message_start.

model: String

attempt: u32

1-based attempt number that succeeded (1 = no retries).

refusal_retries_used: Option<u32>

Number of refusal retries consumed (0 = no refusals). Present only when > 0.

ttft_ms: Option<u64>

Milliseconds from request send to first SSE byte.

total_ms: u64

Milliseconds from request send to stream close.

stop_reason: Option<String>

usage: UsageRecord

ratelimit: Option<RateLimitRecord>

cache_diag: Option<CacheDiagRecord>

context: ContextRecord

keepwarm: bool

true only on prompt-cache keep-warm pings (task #444) so telemetry can separate pings from real turns. Absent on every turn record.

worker: bool

true when a subagent (worker runtime) made the request, so reports can split delegated traffic from the foreground session. Absent on foreground and internal records.
