schema

Represents the status of a run:

• "pending": The run is waiting to start.
• "running": The run is currently executing.
• "error": The run encountered an error and stopped.
• "success": The run completed successfully.
• "timeout": The run exceeded its time limit.
• "interrupted": The run was manually stopped or interrupted.

Represents the status of a thread:

• "idle": The thread is not currently processing any task.
• "busy": The thread is actively processing a task.
• "interrupted": The thread's execution was interrupted.
• "error": An exception occurred during task processing.

Defines the mode of streaming:

• "run_modes": Stream the same events as the runs on thread, as well as run_done events.
• "lifecycle": Stream only run start/end events.
• "state_update": Stream state updates on the thread.

Defines the mode of streaming:

• "values": Stream only the values.
• "messages": Stream complete messages.
• "updates": Stream updates to the state.
• "events": Stream events occurring during execution.
• "checkpoints": Stream checkpoints as they are created.
• "tasks": Stream task start and finish events.
• "debug": Stream detailed debug information.
• "custom": Stream custom events.

Specifies behavior on disconnection:

• "cancel": Cancel the operation on disconnection.
• "continue": Continue the operation even if disconnected.

Defines how to handle multiple tasks:

• "reject": Reject new tasks when busy.
• "interrupt": Interrupt current task for new ones.
• "rollback": Roll back current task and start new one.
• "enqueue": Queue new tasks for later execution.

Specifies behavior on conflict:

• "raise": Raise an exception when a conflict occurs.
• "do_nothing": Ignore conflicts and proceed.

Defines action after completion:

• "delete": Delete resources after completion.
• "keep": Retain resources after completion.

Durability mode for the graph execution.

• "sync": Changes are persisted synchronously before the next step starts.
• "async": Changes are persisted asynchronously while the next step executes.
• "exit": Changes are persisted only when the graph exits.

Represents a wildcard or 'all' selector.

Specifies behavior if the thread doesn't exist:

• "create": Create a new thread if it doesn't exist.
• "reject": Reject the operation if the thread doesn't exist.

Strategy for pruning threads:

• "delete": Remove threads entirely.
• "keep_latest": Prune old checkpoints but keep threads and their latest state.

Action to take when cancelling the run.

• "interrupt": Simply cancel the run.
• "rollback": Cancel the run. Then delete the run and associated checkpoints.

Filter runs by status when bulk-cancelling:

• "pending": Cancel only pending runs.
• "running": Cancel only running runs.
• "all": Cancel all runs regardless of status.

The field to sort by.

The order to sort by.

Stream format version.

• "v1": Traditional format — raw SSE StreamPart NamedTuples.
• "v2": Each event is a typed dict with type, ns, and data keys.

Configuration for LangSmith tracing.

Configuration options for a call.

Represents a checkpoint in the execution process.

Defines the structure and properties of a graph.

Base model for an assistant.

Represents a specific version of an assistant.

Represents an assistant with additional properties.

Paginated response for assistant search results.

Represents an interruption in the execution flow.

Represents a conversation thread.

Represents a task within a thread.

Represents the state of a thread.

Represents the response from updating a thread's state.

Represents a single execution run.

Represents a scheduled task.

Payload for updating a cron job. All fields are optional.

Defines the parameters for initiating a background run.

Represents a single document or data entry in the graph's Store.

Items are used to store cross-thread memories.

Response structure for listing namespaces.

Item with an optional relevance score from search operations.

Response structure for searching items.

Represents a part of a stream response.

Payload for a task start event.

Payload for a task result event.

A task entry within a CheckpointPayload.

The keys present depend on the task's state:

• Error: id, name, error, state
• Has result: id, name, result, interrupts, state
• Pending: id, name, interrupts, state

Payload for a checkpoint event.

Payload for the metadata control event.

Stream part emitted for stream_mode="values".

Stream part emitted for stream_mode="updates".

Stream part emitted for partial message chunks (messages/partial).

Stream part emitted for complete messages (messages/complete).

Stream part emitted for message metadata (messages/metadata).

Stream part emitted for stream_mode="messages" (raw message+metadata pair).

Stream part emitted for stream_mode="custom".

Stream part emitted for stream_mode="checkpoints".

Stream part emitted for stream_mode="tasks".

Stream part emitted for stream_mode="debug".

Control event with run_id and other run metadata.

Represents a message to be sent to a specific node in the graph.

This type is used to explicitly send messages to nodes in the graph, typically used within Command objects to control graph execution flow.

Represents one or more commands to control graph execution flow and state.

This type defines the control commands that can be returned by nodes to influence graph execution. It lets you navigate to other nodes, update graph state, and resume from interruptions.

Metadata for a run creation request.

Represents a JSON-like structure, which can be None or a dictionary with string keys and any values.

Wrapper payload for debug events. Discriminate on type.

Discriminated union of all v2 stream part types.

Use part["type"] to narrow the type.
