Kailash Core SDK - Foundational Skills

Comprehensive guide to Kailash Core SDK fundamentals for workflow automation and integration.

Features

The Core SDK provides the foundational building blocks for creating custom workflows with fine-grained control:

• 110+ Workflow Nodes: Pre-built nodes for AI, API, database, file operations, logic, and more
• WorkflowBuilder API: String-based workflow construction with type safety
• Dual Runtime Support: AsyncLocalRuntime (Docker/async) and LocalRuntime (CLI/scripts)
• Advanced Patterns: Cyclic workflows, conditional execution, error handling
• MCP Integration: Built-in Model Context Protocol support
• Parameter Passing: Flexible data flow between nodes
• Zero Configuration: Auto-detection of runtime context
• Production Ready: Enterprise features including monitoring, validation, and debugging

Quick Start

from kailash.workflow.builder import WorkflowBuilder
from kailash.runtime.local import LocalRuntime

workflow = WorkflowBuilder()
workflow.add_node("NodeName", "id", {"param": "value"})

# Use context manager for proper resource cleanup (recommended)
with LocalRuntime() as runtime:
    results, run_id = runtime.execute(workflow.build())

Key Concepts

Canonical Node Pattern (4-Parameter)

This is the single source of truth for node configuration. All other skills reference this section.

workflow.add_node(
    "NodeClassName",  # 1. Node type (PascalCase, string)
    "unique_node_id", # 2. Unique ID (snake_case, string)
    {                 # 3. Configuration dict
        "param1": "value",
        "param2": 123
    },
    connections=[]    # 4. Optional: input connections
)

Connection Methods:

# Method 1: add_connection (4-positional params - explicit)
workflow.add_connection("read_file", "content", "transform", "input")

# Method 2: connect (flexible API with keyword args)
workflow.connect("read_file", "transform", from_output="content", to_input="input")

# Method 3: connect with mapping (multiple outputs)
workflow.connect("node1", "node2", mapping={"content": "input", "meta": "metadata"})

WorkflowBuilder Pattern

• String-based node API: workflow.add_node("NodeName", "id", {})
• Always call .build() before execution
• Never workflow.execute(runtime) - always runtime.execute(workflow.build())

Runtime Selection

• AsyncLocalRuntime: For Docker/async (async contexts) - async-first, no threading, 10-100x faster
• LocalRuntime: For CLI/scripts (sync contexts) - synchronous execution with thread support
• get_runtime(): Auto-detection helper that selects appropriate runtime based on context

Both runtimes return identical structure: (results, run_id) tuple.

Runtime Architecture

Both LocalRuntime and AsyncLocalRuntime inherit from BaseRuntime with shared capabilities:

BaseRuntime Foundation:

• 29 configuration parameters (debug, enable_cycles, conditional_execution, connection_validation, etc.)
• Execution metadata management
• Common initialization and validation modes (strict, warn, off)

Shared Mixins:

• CycleExecutionMixin: Cyclic workflow execution with validation
• ValidationMixin: Workflow structure validation (5 methods)
• ConditionalExecutionMixin: Conditional execution and branching with SwitchNode support

AsyncLocalRuntime-Specific:

• WorkflowAnalyzer for optimal execution strategy
• Level-based parallelism for concurrent execution
• Thread pool for sync nodes without blocking
• Semaphore control to prevent resource exhaustion

Critical Rules

• ✅ ALWAYS: runtime.execute(workflow.build())
• ✅ String-based nodes: workflow.add_node("NodeName", "id", {})
• ✅ 4-parameter connections: (source_id, source_param, target_id, target_param)
• ✅ Docker/async: Use AsyncLocalRuntime (mandatory)
• ✅ CLI/Scripts: Use LocalRuntime
• ❌ NEVER: workflow.execute(runtime)
• ❌ NEVER: Instance-based nodes
• ❌ NEVER: Use LocalRuntime in Docker (causes hangs)
