Streaming events emitted to the SSE client.

Variants

ThreadAssigned

Sent first, once we know which thread we’re posting to (creating a new one if the request didn’t supply an id).

Fields

thread_id: String

title: String

Text

Assistant text delta.

Fields

delta: String

ToolStart

Tool call has begun (after the model finishes producing its input).

Fields

id: String

name: String

input: Value

ToolEnd

Tool produced a result (or error) — the agent is about to send it back to the model.

Fields

id: String

output: String

is_error: bool

EditPending

edit_file tool has stashed a proposal and is now blocked waiting on the user’s accept/reject. The client should render a diff card and a pending bottom-bar; resolution comes via POST /:ws/_/chat/edits/{id}/{apply|reject}.

Fields

id: String

Pending-edit id, matches the URL segment of the resolve endpoint.

tool_use_id: String

Tool-use id from the originating tool_use block, so the client can correlate this card with the right turn.

path: String

Workspace-relative path the model proposed editing.

line: usize

1-based line number of old_string’s first character at propose-time.

old_string: String

new_string: String

TurnEnd

One full provider turn ended; agent may loop again with tool results.

Fields

stop_reason: String

usage: Usage

Done

The whole agent loop has ended for this user turn.

Fields

total_usage: Usage

final_message_seq: Option<i64>

Error

Fatal error; stream is about to close.

Fields

message: String
