krysta 1.0.7

A unified multimodal model evaluation tracking and engineering report engine.

NoA Python SDK API Reference Documentation

This document provides technical reference details for the classes, methods, parameters, and streaming response objects available within the krysta client library.

Core Class Architecture

NoA Class

The main client manager used to initialize connections and manage state lifecycle pipes with your remote execution infrastructure gateway.

from krysta.noa import Noa

Class Constructor Matrix

Noa()

• Parameters:
  • gateway_url (str, Optional): The network address of your custom backend execution gateway. If omitted, the SDK connects automatically to the hosted Krysta live cloud server.

Context Manager Methods

The client class fully implements the standard asynchronous context manager layout (__aenter__ / __aexit__) to automatically handle network streams, channel allocations, and memory resource cleanups safely.

# Connects to the cloud automatically with zero config
async with Noa() as client:
    # Execution resources are automatically allocated here
    pass
# Connection pipes are safely destroyed here

Method Reference Maps

execute()

Initiates an asynchronous Server-Sent Events (SSE) background task worker thread to evaluate a raw source code string.

Method Definition Syntax

def execute(
    language: str, 
    code: str, 
    timeout_ms: int = 5000
) -> AsyncIterator[dict]:

Input Arguments Block

• language (str, Required): The programming compilation runner target environment to spawn inside the isolated cluster node. Supported strings:
  • "python"
  • "javascript"
• code (str, Required): The uncompiled text string payload containing the raw source code script to evaluate inside the container pool.
• timeout_ms (int, Optional): The strict maximum allowed execution time window in milliseconds before the watchdog thread hard-kills (SIGKILL) the task runner. Default fallback threshold value: 5000.

Return Type Value

• Returns an AsyncIterator[dict] stream generator object. You must consume this data payload frame-by-frame using an async for loop layout block.

Stream Event Response Payload Schema

Every data unit emitted from the async iterator returns a structured Python dict map object containing the following token parameters:

{
  "type": "system" | "stdout" | "stderr" | "rules" | "done" | "error",
  "text": "string" | null,
  "timestamp": integer
}

Event Parameter Types Definition Matrix

1. type: "system"

Emitted immediately when the gateway server begins allocating memory allocations or scheduling task execution queues.

• Text Contents: Standard tracking message flags (e.g., "EXECUTION_STARTED").

2. type: "stdout"

Emitted instantly whenever the sandboxed script writes characters to the standard console system output.

• Text Contents: The raw printed string text data.

3. type: "stderr"

Emitted instantly when unhandled runtime errors, system exceptions, or line code tracebacks occur inside the isolated runner.

• Text Contents: Standard multiline traceback exception information text.

4. type: "rules"

Emitted near task termination. Contains a serialized JSON string listing static metric quality scores and evaluation check markers.

• Text Contents Schema:

  "[{\"rule\": \"ExitCodeZeroRule\", \"result\": \"PASS\" | \"FAIL\", \"reason\": \"...\"}]"
  

5. type: "done"

Emitted when the execution lifecycle pipeline completes its loop naturally and closes down successfully.

• Text Contents: null

6. type: "error"

Emitted if a network drop occurs, or if the server cannot complete an internal spawn routing operation.

• Text Contents: Detailed platform failure tracking notes (e.g., "Job failed during execution").
