StreamState

When True, stream-time diagnostics (the tool-call and file-operation notifications, plus the stdout separator newline preceding a tool call) are suppressed, so stdout carries only agent response text.

When True (default), text chunks are written to stdout as they arrive.

When False, text is buffered in full_response and flushed after the agent finishes.

Accumulated text fragments from the AI message stream.

Maps a tool-call index or ID to its in-progress buffer: name, ID, accumulated argument fragments, and the display latch.

Maps in-flight tool-call IDs (those whose tool.use has fired) to their name and parsed arguments, so the matching tool.result can be correlated. Entries are removed when the result arrives; any still present when the stream aborts are closed by _dispatch_orphaned_tool_result_hooks. One record per id keeps name and args structurally in lock-step (see InFlightToolCall).

Tool-call IDs whose non-interactive call line has already been printed.

Tool-call IDs for which a tool.use has been dispatched.

Monotonic: never cleared within a run, so tool.use fires at most once per id even if a call's arg chunks are redelivered after its result (mirrors the TUI's displayed_tool_ids). Result correlation and the orphan drain use the separate in_flight_tool_calls, which is cleared per result.

Maps interrupt IDs to their validated HITL requests that are awaiting decisions.

Maps interrupt IDs to dicts containing a 'decisions' key with a list of decision dicts (each having a 'type' key of 'approve' or 'reject').

Used to resume the agent after HITL processing.

Flag indicating whether any HITL interrupt was received during the current stream pass.

Accumulated model usage stats for this stream.

Optional animated spinner shown during agent work in verbose mode.

Whether rubric lifecycle messages should include iteration numbers.
