Struct SessionWritesLostMessage 

pub struct SessionWritesLostMessage {
    pub error_code: SessionWriteErrorCode,
    pub lost: Vec<LostSessionWrite>,
    pub transcript_session_ids: Option<Vec<String>>,
    pub uuid: String,
    pub session_id: String,
}

system/session_writes_lost — the CLI could not save lines of a session transcript, changes to ~/.claude.json, or both, because the disk was full or its quota was used up. Sent at most once, as the CLI exits, after the last result if there was one. The results already received stand, and this message does not change the exit status. Sent only with stream-json output on stdout, never under --sdk-url or a Claude Desktop entrypoint. Safe to ignore (CLI 2.1.317+).

Fields

error_code: SessionWriteErrorCode

Why the writes failed. When both kinds of write were lost for different reasons, the transcript’s.

lost: Vec<LostSessionWrite>

What was not saved. Never empty.

transcript_session_ids: Option<Vec<String>>

The sessions whose transcripts lost lines, in the order each first lost one. Present only when LostSessionWrite::Transcript is listed; never empty. Usually session_id alone; a CLI that started a new session after the loss (as /clear does) lists the earlier session, and lists session_id only if that session lost lines too.

uuid: String

session_id: String

The session the CLI is in, as on every message; see transcript_session_ids for whose transcript lost lines.
