Module protocol 

JSONL framing, JSON-RPC 2.0 types, RPC command/response/event types, and serialization helpers.

Structs

CommandInfo

Command info for get_commands response

CompactionResult

Result of compaction

ImageData

Image data for RPC commands

JsonRpcError

JSON-RPC 2.0 error object

JsonRpcErrorResponse

JSON-RPC 2.0 error response

JsonRpcRequest

JSON-RPC 2.0 request

JsonRpcSuccessResponse

JSON-RPC 2.0 success response

JsonlLineReader

A strict JSONL line reader that splits on LF only (not CR or other separators). This is important because JSON strings may contain U+2028/U+2029 which Node.js readline would incorrectly split on.

ModelInfo

Model information for session state

PendingExtensionRequest

Tracks pending extension UI requests awaiting client responses.

RpcImageSource

Base64-encoded image data

RpcOutput

Thread-safe output writer that ensures atomic JSONL writes.

SessionHandoff

Information about a session for handoff between processes.

SessionState

Session state for get_state response

SessionStats

Result of a session stat query

SourceInfo

Source info for command provenance

Enums

RpcCommand

RPC command from client

RpcEvent

Events emitted by the RPC server to the client during streaming.

RpcExtensionUiRequest

Extension UI request

RpcExtensionUiResponse

Extension UI response from client

RpcResponse

RPC response to client

Constants

JSONRPC_INTERNAL_ERROR

JSON-RPC internal error code.

JSONRPC_INVALID_PARAMS

JSON-RPC invalid params error code.

JSONRPC_INVALID_REQUEST

JSON-RPC invalid request error code.

JSONRPC_METHOD_NOT_FOUND

JSON-RPC method-not-found error code.

JSONRPC_PARSE_ERROR

JSON-RPC parse error code.

Functions

jsonrpc_to_command

Map a JSON-RPC 2.0 method + params to an internal RPC command value.

parse_json_line

Parse a JSONL line, trimming any trailing CR.

rpc_response_to_jsonrpc

Convert an internal RpcResponse to a JSON-RPC 2.0 response.

serialize_json_line

Serialize a value as a strict JSONL record (JSON + LF).

serialize_json_line_obj

Serialize a serializable value as a JSONL record.
