}

Real-time session state for live monitoring and watch operations.

Tracks cumulative metrics, token usage, and context window state as events stream in. Used by the watch service to provide live updates.

Fields

session_id: String

Session UUID.

project_root: Option<PathBuf>

Project root directory, if known.

log_path: Option<PathBuf>

Path to the session’s log file.

start_time: DateTime<Utc>

Session start timestamp.

last_activity: DateTime<Utc>

Timestamp of the most recent event.

model: Option<String>

Model name/ID being used in this session.

context_window_limit: Option<u64>

Maximum context window size for the model.

current_usage: ContextWindowUsage

Current cumulative token usage.

current_reasoning_tokens: i32

Current cumulative reasoning tokens (o1-style extended thinking).

error_count: u32

Count of errors encountered so far.

event_count: usize

Total number of events processed.

turn_count: usize

Total number of user turns.
