ToolCallStarted

Fields

id: String

name: String

args: Value

ToolCallProgress

Fields

id: String

chunk: ProgressChunk

ToolCallCompleted

Fields

id: String

result: UiToolResult

AgentTurnComplete

PermissionRequested

Fields

tool: String

args: Value

resolver: Sender<Decision>

InlineBashOutput

Output of a !!cmd inline-bash run, for transcript display.

Fields

command: String

output: String

SessionReplaced(Vec<Message>)

The session was replaced (/new cleared it, or /resume loaded a stored one). Carries the new transcript so the TUI can rebuild state.messages. Empty Vec = a fresh session.

ModelSwitched(ModelId)

The active model changed successfully.

ForkCandidates(Vec<(String, String)>)

Refreshed /fork candidate list (active-branch user messages, newest first) — (EntryId, preview) pairs. The binary emits this at startup and after every turn so the picker is never stale.

BranchTree(BranchTree)

Refreshed session branch tree — the binary emits this at startup and after every turn so the /tree view is never stale.

MessagesSnapshot(Vec<Message>)

Reply to Command::GetMessages — the session’s persisted message history. RPC clients use this to snapshot transcript state.

StateSnapshot

Reply to Command::GetState — a small status snapshot for RPC clients (the TUI holds these in AppState so does not need it).

Fields

session_id: String

model: String

active_turn: bool

Error(String)
