Module Contents

type roboto.ai.core.record.AgentContent = AgentTextContent | AgentToolUseContent | AgentToolResultContent | AgentErrorContent

Type alias for all possible content types within agent messages.

class roboto.ai.core.record.AgentContentType

Bases: roboto.compat.StrEnum

Enumeration of different types of content within agent messages.

Defines the various content types that can be included in agent messages.

ERROR = 'error'

Error information when message generation fails.

TEXT = 'text'

Plain text content from users or AI responses.

TOOL_RESULT = 'tool_result'

Results returned from tool executions.

TOOL_USE = 'tool_use'

Optional error code for programmatic handling.

error_message: str

User-friendly error message describing what went wrong.

class roboto.ai.core.record.AgentGoalStatus

Bases: roboto.compat.StrEnum

Lifecycle of a per-turn declared goal.

Goals begin PENDING when registered. They transition to ACHIEVED when the corresponding achieve-tool reports success, or to FAILED when the runner’s corrective re-prompt budget for the turn is exhausted (or when the worker cannot construct an achieve-tool for the goal).

ACHIEVED = 'achieved'

Goal’s corresponding achieve-tool was invoked successfully.

FAILED = 'failed'

PENDING = 'pending'

Goal has been registered but not yet completed.

class roboto.ai.core.record.AgentMessage(/, **data)

Bases: pydantic.BaseModel

A single message within an agent session.

Represents one message in the conversation, containing the sender role, content blocks, and generation status. Messages can contain multiple content blocks of different types (text, tool use, tool results).

Parameters:

data (Any)

content: list[AgentContent]

List of content blocks that make up this message.

created: datetime.datetime = None

Timestamp when this message was created.

is_complete()

Check if message generation is complete.

Returns:

True if the message status is COMPLETED, False otherwise.

Return type:

bool

is_unsuccessful()

Check if message generation failed or was cancelled.

Returns:

True if the message status is FAILED or CANCELLED, False otherwise.

Return type:

bool

role: AgentRole

The role of the message sender (user, assistant, or roboto).

status: AgentMessageStatus

Message generation failed due to an error.

GENERATING = 'generating'

Message content is currently being generated.

NOT_STARTED = 'not_started'

Message has been queued but generation has not begun.

is_terminal()

Check if the message generation is in a terminal state.

Returns:

True if the message is in a terminal state, False otherwise.

Return type:

bool

class roboto.ai.core.record.AgentRole

Bases: roboto.compat.StrEnum

Enumeration of possible roles in an agent session.

Defines the different participants that can send messages in a session.

ASSISTANT = 'assistant'

class roboto.ai.core.record.AgentSessionDelta(/, **data)

Bases: pydantic.BaseModel

Incremental update to an agent session.

Contains only the changes since the last synchronization, used for efficient real-time updates without transferring the entire session history.

Parameters:

data (Any)

continuation_token: str

Updated token for the next incremental synchronization.

goals: list[AgentSessionGoalRecord] | None = None

Latest snapshot of every goal declared in the session, ordered by allocation. None means there has been no change since the previous delta — clients should retain the snapshot they already hold. An empty list means the session has no declared goals. A non-empty list is the authoritative current snapshot and replaces any prior value.

messages_by_idx: dict[int, AgentMessage]

New or updated messages indexed by their position in the conversation.

status: AgentSessionStatus | None = None

Updated status of the agent session.

title: str | None = None

Updated title of the agent session.

class roboto.ai.core.record.AgentSessionGoalRecord(/, **data)

Bases: pydantic.BaseModel

Customer-visible read shape of a goal declared on an agent session.

Parameters:

data (Any)

concluded_at: datetime.datetime | None = None

Timestamp when the goal transitioned to a terminal state (ACHIEVED or FAILED). None while the goal is still PENDING.

created: datetime.datetime

Timestamp when the goal was registered.

goal_data: dict[str, Any]

The validated goal payload as JSON. Use to_agent_goal() to recover the typed model the caller declared.

goal_type: str

Discriminator selecting which AgentGoal model the goal_data payload conforms to (e.g. "dataset_summary").

message_sequence_num: int

Index in the session’s full messages list of the AgentRole.USER message that declared this goal. Use to render goals adjacent to the turn they were attached to.

status: AgentGoalStatus

Current lifecycle state of the goal.

to_agent_goal()

Re-hydrate goal_data into the typed AgentGoal the caller declared.

Returns:

The validated, discriminated AgentGoal instance — for "dataset_summary" rows, a DatasetSummaryAgentGoal; for "dataset_triage" rows, a DatasetTriageGoal; etc.

Return type:

roboto.ai.goals.AgentGoal

class roboto.ai.core.record.AgentSessionRecord(/, **data)

Bases: pydantic.BaseModel

Backwards-compatible alias — serialized as chat_id in API responses.

Return type:

str

continuation_token: str

Token used for incremental updates and synchronization.

created: datetime.datetime

Timestamp when this agent session was created.

If this session was forked, the id of the source session. None otherwise.

goals: list[AgentSessionGoalRecord] | None = None

Goals declared across this session’s turns, ordered by allocation (i.e. by goal_index). None means goals were not loaded for this record (full-session reads populate the field; lightweight or legacy reads may omit it). An empty list means goals were loaded but the session never declared any.

class roboto.ai.core.record.AgentSessionStatus

Bases: roboto.compat.StrEnum

Enumeration of possible agent session states.

Tracks the overall status of an agent session from creation to termination.

CLIENT_TOOL_TURN = 'client_tool_turn'

Client must execute pending tool uses and submit results.

text: str

The actual text content of the message.

class roboto.ai.core.record.AgentToolResultContent(/, **data)

Bases: pydantic.BaseModel

Tool execution result content within an agent message.

Parameters:

data (Any)

content_type: Literal[AgentContentType]

raw_response: dict[str, Any] | None = None

Raw, unparsed response payload from tool execution.

runtime_ms: int

Wall-clock execution time of the tool in milliseconds.

status: str

Outcome of the tool execution (e.g. ‘success’, ‘error’).

tool_name: str

Name of the tool that was executed.

tool_use_id: str

Identifier of the tool invocation this result corresponds to.

class roboto.ai.core.record.AgentToolUseContent(/, **data)

Bases: pydantic.BaseModel

Tool usage request content within an agent message.

Parameters:

data (Any)

content_type: Literal[AgentContentType]

input: dict[str, Any] | None = None

Parsed tool input parameters chosen by the LLM (provider-agnostic).

raw_request: dict[str, Any] | None = None

Raw, unparsed request payload for this tool invocation.

tool_name: str

Name of the tool the LLM is requesting to invoke.

tool_use_id: str

Unique identifier for this tool invocation, used to correlate with its result.

roboto.ai.core.record.CLIENT_TOOL_NAME_PREFIX = 'client_'

Required prefix for every client-declared tool name.

Distinguishes client tools from server-side tools at every layer (API, SDK, UI, Bedrock toolConfig) without ambiguity. Underscore is used rather than a colon so the resulting name still matches Bedrock’s Converse toolSpec.name pattern (^[a-zA-Z][a-zA-Z0-9_]*$).

class roboto.ai.core.record.ClientToolSpec(/, **data)

Bases: pydantic.BaseModel

Declarative specification for a client-side tool.

Unlike AgentTool (which is an ABC with a __call__ method for server-side execution), ClientToolSpec is a plain data model. The backend includes it in the LLM’s tool list but never executes it — the client is responsible for execution and submitting the result.

Parameters:

data (Any)

description: str

input_schema: dict[str, Any]

name: str

class roboto.ai.core.record.ModelProfileResponse(/, **data)

Bases: pydantic.BaseModel

Metadata about an available model profile, returned by the API.

Parameters:

data (Any)

description: str

Short description of the profile’s characteristics.

id: str

Profile identifier, e.g. ‘standard’ or ‘advanced’.

is_default: bool = False

Whether this profile is selected by default for new sessions.

label: str

Human-readable display label.
