+### Context Read/Write Configuration
+
+Nodes can specify which context keys they read from and write to, enabling declarative context management.
+
+#### Context Read Configuration
+
+Nodes can declare which context keys they need to read before execution:
+
+```python
+# Action node that reads user name from context
+action_node = ActionNode(
+ name="weather_action",
+ action=get_weather,
+ context_read=["user.name", "user.preferences"], # Read these keys from context
+ description="Get weather with user preferences"
+)
+```
+
+#### Context Write Configuration
+
+Nodes can declare which context keys they will write after execution:
+
+```python
+# Action node that writes to context
+action_node = ActionNode(
+ name="remember_name_action",
+ action=remember_name,
+ context_write=["user.name", "user.first_seen"], # Write these keys to context
+ description="Remember user's name"
+)
+```
+
+#### Parameter Key Configuration
+
+Action nodes can specify which parameter keys to check for parameters:
+
+```python
+# Action node with custom parameter keys
+action_node = ActionNode(
+ name="weather_action",
+ action=get_weather,
+ param_keys=["location_params", "extracted_params"], # Check these keys for parameters
+ context_read=["user.name"],
+ description="Get weather for location"
+)
+```
+
+#### Context-Aware Action Functions
+
+Action functions can access context data through the `**kwargs` parameter:
+
+```python
+def get_weather(location: str, **kwargs) -> str:
+ """Get weather with context awareness."""
+ # Access context data
+ user_name = kwargs.get('user.name')
+ preferences = kwargs.get('user.preferences', {})
+
+ if user_name:
+ return f"Hey {user_name}! The weather in {location} is sunny."
+ else:
+ return f"The weather in {location} is sunny."
+```
+
+#### Context Persistence Example
+
+```python
+# Create a DAG with context persistence
+builder = DAGBuilder()
+
+# Add extractor that writes to specific key
+builder.add_node(
+ "extract_name",
+ "extractor",

+# Clarification Nodes
+
+Clarification nodes handle ambiguous or incomplete user input by asking for additional information. They enable multi-turn conversations and improve user experience by gathering missing details.
+
+## Overview
+
+Clarification nodes:
+- Detect when user input is unclear or incomplete
+- Present structured options for user selection
+- Support multi-turn conversation flows
+- Provide context-aware clarification messages
+- Handle user responses and route appropriately
+
+## Basic Usage
+
+```python
+from intent_kit import DAGBuilder
+
+# Create a clarification node
+builder.add_node("booking_clarification", "clarification",
+ clarification_message="I need more information to help you with your booking.",
+ available_options=[
+ "Make a restaurant reservation",
+ "Book a flight",
+ "Reserve a hotel room"
+ ],
+ output_key="clarification_response")
+```
+
+## Configuration Options
+
+### Clarification Message
+
+The message presented to the user when clarification is needed:
+
+```python
+builder.add_node("clarification", "clarification",
+ clarification_message="""
+ I'm not sure what type of booking you'd like to make.
+ Please select from the options below:
+ """,
+ available_options=["Restaurant", "Flight", "Hotel"])
+```
+
+### Available Options
+
+Provide structured options for user selection:
+
+```python
+# Simple text options
+available_options = [
+ "Book a restaurant table",
+ "Reserve a flight",
+ "Book a hotel room"
+]
+
+# Or with more descriptive options
+available_options = [
+ "🍽️ Restaurant - Make a dining reservation",
+ "✈️ Flight - Book air travel",
+ "🏨 Hotel - Reserve accommodation"
+]
+```
+
+### Output Key
+
+Specify where the user's response should be stored:
+
+```python
+builder.add_node("clarification", "clarification",
+ clarification_message="What would you like to do?",
+ available_options=["Option A", "Option B"],
+ output_key="user_selection") # Response stored in context under this key
+```
+
+## Advanced Configuration
+
+### Custom Response Handling
+
+```python
+builder.add_node("smart_clarification", "clarification",
+ clarification_message="Please specify your preference:",
+ available_options=["Budget", "Luxury", "Mid-range"],
+ output_key="preference",
+ custom_response_handler=lambda response: {
+ "preference": response.lower(),
+ "confidence": 0.9
+ })
+```
+
+### Context-Aware Messages
+
+```python
+# Use context to personalize clarification messages
+def get_clarification_message(context):
+ user_name = context.get("user_name", "there")
+ return f"Hi {user_name}, I need a bit more information to help you."
+
+builder.add_node("personalized_clarification", "clarification",
+ clarification_message=get_clarification_message,
+ available_options=["Option 1", "Option 2"])
+```
+
+## Multi-Turn Conversations
+
+Clarification nodes enable sophisticated multi-turn conversations:
+
+```python
+# First clarification - determine intent
+builder.add_node("intent_clarification", "clarification",
+ clarification_message="What would you like to do?",
+ available_options=["Book travel", "Make reservation", "Get information"],
+ output_key="intent")
+
+# Second clarification - based on first response
+builder.add_node("travel_clarification", "clarification",
+ clarification_message="What type of travel?",
+ available_options=["Flight", "Train", "Bus", "Car rental"],
+ output_key="travel_type")
+
+# Connect the flow
+builder.add_edge("intent_clarification", "travel_clarification", "Book travel")
+```
+
+## Integration Patterns
+
+### With Classifier Nodes
+
+```python
+# Classifier routes to clarification when intent is unclear
+builder.add_edge("intent_classifier", "clarification", "unclear_intent")
+builder.add_edge("clarification", "intent_classifier", "clarified")
+```
+
+### With Extractor Nodes
+
+```python
+# Clarification can provide missing parameters for extraction
+builder.add_edge("extractor", "clarification", "missing_params")
+builder.add_edge("clarification", "extractor", "params_provided")
+```
+
+### With Action Nodes
+
+```python
+# Clarification can route to different actions based on user choice
+builder.add_edge("clarification", "restaurant_action", "restaurant_selected")
+builder.add_edge("clarification", "flight_action", "flight_selected")
+```
+
+## Error Handling
+
+### Invalid Responses
+
+```python
+# Handle cases where user provides unexpected input
+builder.add_node("robust_clarification", "clarification",
+ clarification_message="Please select from the options:",
+ available_options=["A", "B", "C"],
+ fallback_message="I didn't understand. Please choose A, B, or C.")
+```
+
+### Timeout Handling
+
+```python
+# Handle cases where user doesn't respond
+builder.add_node("timeout_clarification", "clarification",
+ clarification_message="Please respond within 30 seconds:",
+ available_options=["Yes", "No"],
+ timeout_seconds=30,
+ timeout_message="No response received. Please try again.")
+```
+
+## Best Practices
+
+### 1. Clear and Specific Options
+
+```python
+# Good: Clear, specific options
+available_options = [
+ "Book a table for 2 people",
+ "Book a table for 4+ people",
+ "Check restaurant availability",
+ "Cancel existing reservation"
+]
+
+# Avoid: Vague options
+available_options = [
+ "Book",
+ "Check",
+ "Cancel"
+]
+```
+
+### 2. Progressive Disclosure
+
+```python
+# Start with broad categories, then get specific
+# First clarification
+builder.add_node("category_clarification", "clarification",
+ clarification_message="What type of service do you need?",
+ available_options=["Travel", "Dining", "Entertainment"])
+
+# Second clarification (after travel selected)
+builder.add_node("travel_type_clarification", "clarification",
+ clarification_message="What type of travel?",
+ available_options=["Flight", "Hotel", "Car rental", "Package deal"])
+```
+
+### 3. Context Preservation
+
+```python
+# Preserve context across clarification turns
+def handle_clarification_response(context, response):
+ # Store the clarification response
+ context.set("clarification_response", response)
+
+ # Preserve original user input
+ original_input = context.get("original_input")
+ context.set("full_conversation", f"{original_input} -> {response}")
+
+ return response
+```
+
+### 4. Graceful Degradation
+
+```python
+# Provide fallback options when clarification fails
+builder.add_node("fallback_clarification", "clarification",
+ clarification_message="I'm having trouble understanding. Please try again:",
+ available_options=["Option A", "Option B", "Start over"],
+ max_attempts=3)
+```
+
+## Examples
+
+### Restaurant Booking Flow
+
+```python
+# Determine booking type
+builder.add_node("booking_type_clarification", "clarification",
+ clarification_message="What type of booking would you like to make?",
+ available_options=[
+ "Dinner reservation",
+ "Lunch reservation",
+ "Private event",
+ "Catering order"
+ ],
+ output_key="booking_type")
+
+# Determine party size
+builder.add_node("party_size_clarification", "clarification",
+ clarification_message="How many people will be in your party?",
+ available_options=[
+ "1-2 people",
+ "3-4 people",
+ "5-8 people",
+ "9+ people"
+ ],
+ output_key="party_size")
+```
+
+### Travel Planning Flow
+
+```python
+# Determine travel purpose
+builder.add_node("travel_purpose_clarification", "clarification",
+ clarification_message="What's the purpose of your trip?",
+ available_options=[
+ "Business travel",
+ "Vacation/leisure",
+ "Family visit",
+ "Other"
+ ],
+ output_key="travel_purpose")
+
+# Determine budget range
+builder.add_node("budget_clarification", "clarification",
+ clarification_message="What's your budget range?",
+ available_options=[
+ "Budget-friendly ($)",
+ "Mid-range ($$)",
+ "Luxury ($$$)"
+ ],
+ output_key="budget_range")
+```
+
+### Customer Support Flow
+
+```python
+# Determine issue category
+builder.add_node("issue_category_clarification", "clarification",
+ clarification_message="What type of issue are you experiencing?",
+ available_options=[
+ "Technical problem",
+ "Billing question",
+ "Account access",
+ "General inquiry"
+ ],
+ output_key="issue_category")
+
+# Determine urgency
+builder.add_node("urgency_clarification", "clarification",
+ clarification_message="How urgent is this issue?",
+ available_options=[
+ "Critical - Service completely down",
+ "High - Major functionality affected",
+ "Medium - Minor inconvenience",
+ "Low - General question"
+ ],
+ output_key="urgency_level")
+```
+
+## Performance Considerations
+
+### Response Time
+
+```python
+# Set appropriate timeouts for different contexts
+builder.add_node("quick_clarification", "clarification",
+ clarification_message="Quick question:",
+ available_options=["Yes", "No"],
+ timeout_seconds=10) # Short timeout for simple questions
+
+builder.add_node("detailed_clarification", "clarification",
+ clarification_message="Please provide detailed information:",
+ available_options=["Option A", "Option B", "Option C"],
+ timeout_seconds=60) # Longer timeout for complex decisions
+```
+
+### Memory Management
+
+```python
+# Clear old clarification context to prevent memory bloat
+def cleanup_clarification_context(context):
+ # Keep only recent clarification history
+ clarification_history = context.get("clarification_history", [])
+ if len(clarification_history) > 5:
+ context.set("clarification_history", clarification_history[-5:])
+```

+# Context Management
+
+Intent Kit provides a sophisticated context management system that enables stateful execution, dependency tracking, and deterministic behavior across DAG traversals.
+
+## Overview
+
+The context system consists of several key components:
+
+- **ContextProtocol** - Interface for context implementations
+- **DefaultContext** - Standard context implementation
+- **ContextPatch** - Mechanism for applying changes during traversal
+- **Merge Policies** - Rules for combining context data
+- **Fingerprinting** - Deterministic context identification for memoization
+
+## Core Concepts
+
+### Context Protocol
+
+The `ContextProtocol` defines the interface that all context implementations must follow:
+
+```python
+from intent_kit.core.context import ContextProtocol
+
+class ContextProtocol(Protocol):
+ # Core key-value operations
+ def get(self, key: str, default: Any = None) -> Any: ...
+ def set(self, key: str, value: Any, modified_by: Optional[str] = None) -> None: ...
+ def has(self, key: str) -> bool: ...
+ def keys(self) -> Iterable[str]: ...
+
+ # Patching and snapshots
+ def snapshot(self) -> Mapping[str, Any]: ...
+ def apply_patch(self, patch: ContextPatch) -> None: ...
+ def merge_from(self, other: Mapping[str, Any]) -> None: ...
+
+ # Deterministic fingerprinting
+ def fingerprint(self, include: Optional[Iterable[str]] = None) -> str: ...
+
+ # Telemetry and logging
+ @property
+ def logger(self) -> LoggerLike: ...
+
+ # Error and operation tracking
+ def add_error(self, *, where: str, err: str, meta: Optional[Mapping[str, Any]] = None) -> None: ...
+ def track_operation(self, *, name: str, status: str, meta: Optional[Mapping[str, Any]] = None) -> None: ...
+```
+
+### Default Context
+
+The `DefaultContext` provides a complete implementation of the context protocol:
+
+```python
+from intent_kit.core.context import DefaultContext
+
+# Create a new context
+context = DefaultContext()
+
+# Set values
+context.set("user.name", "Alice")
+context.set("session.id", "session_123")
+context.set("preferences.language", "en")
+
+# Get values
+name = context.get("user.name") # "Alice"
+language = context.get("preferences.language", "en") # "en"
+
+# Check existence
+if context.has("user.name"):
+ print("User name is set")
+
+# Get all keys
+all_keys = list(context.keys()) # ["user.name", "session.id", "preferences.language"]
+```
+
+## Context Patches
+
+Context patches are the mechanism by which nodes can modify context during DAG traversal. They provide:
+
+- **Atomic updates** - All changes are applied together
+- **Audit trail** - Provenance tracking for changes
+- **Merge policies** - Configurable rules for combining data
+- **Memoization control** - Tags to control caching behavior
+
+### Creating Patches
+
+```python
+from intent_kit.core.context import ContextPatch, MergePolicyName
+
+# Basic patch
+patch: ContextPatch = {
+ "data": {
+ "user.name": "Alice",
+ "session.id": "session_123"
+ },
+ "provenance": "extract_user_info"
+}
+
+# Patch with merge policies
+patch_with_policies: ContextPatch = {
+ "data": {
+ "user.name": "Alice",
+ "preferences.language": "en",
+ "conversation.history": ["Hello", "How are you?"]
+ },
+ "policy": {
+ "user.name": "last_write_wins",
+ "preferences.language": "first_write_wins",
+ "conversation.history": "append_list"
+ },
+ "provenance": "greeting_node",
+ "tags": {"affects_memo"}
+}
+```
+
+### Applying Patches
+
+```python
+from intent_kit.core.context import DefaultContext, ContextPatch
+
+context = DefaultContext()
+
+# Create and apply patch
+patch: ContextPatch = {
+ "data": {"user.name": "Alice"},
+ "provenance": "user_extraction"
+}
+
+context.apply_patch(patch)
+print(context.get("user.name")) # "Alice"
+```
+
+## Merge Policies
+
+Merge policies define how context values are combined when conflicts occur:
+
+### Available Policies
+
+```python
+from intent_kit.core.context import MergePolicyName
+
+# last_write_wins - Latest value overwrites previous
+policy1: MergePolicyName = "last_write_wins"
+
+# first_write_wins - First value is preserved
+policy2: MergePolicyName = "first_write_wins"
+
+# append_list - Values are appended to a list
+policy3: MergePolicyName = "append_list"
+
+# merge_dict - Dictionaries are merged recursively
+policy4: MergePolicyName = "merge_dict"
+
+# reduce - Custom reduction function is applied
+policy5: MergePolicyName = "reduce"
+```
+
+### Policy Examples
+
+```python
+from intent_kit.core.context import DefaultContext, ContextPatch
+
+context = DefaultContext()
+
+# Example 1: last_write_wins
+context.set("user.name", "Bob")
+patch1: ContextPatch = {
+ "data": {"user.name": "Alice"},
+ "policy": {"user.name": "last_write_wins"},
+ "provenance": "update_user"
+}
+context.apply_patch(patch1)
+print(context.get("user.name")) # "Alice"
+
+# Example 2: append_list
+context.set("conversation.history", ["Hello"])
+patch2: ContextPatch = {
+ "data": {"conversation.history": ["How are you?"]},
+ "policy": {"conversation.history": "append_list"},
+ "provenance": "greeting"
+}
+context.apply_patch(patch2)
+print(context.get("conversation.history")) # ["Hello", "How are you?"]
+
+# Example 3: merge_dict
+context.set("user.preferences", {"language": "en", "theme": "dark"})
+patch3: ContextPatch = {
+ "data": {"user.preferences": {"theme": "light", "notifications": True}},
+ "policy": {"user.preferences": "merge_dict"},
+ "provenance": "update_preferences"
+}
+context.apply_patch(patch3)
+print(context.get("user.preferences")) # {"language": "en", "theme": "light", "notifications": True}
+```
+
+## Context Fingerprinting
+
+Fingerprinting provides deterministic identification of context state for memoization:
+
+```python
+from intent_kit.core.context import DefaultContext
+
+context = DefaultContext()
+
+# Set some values
+context.set("user.name", "Alice")
+context.set("session.id", "session_123")
+
+# Get fingerprint of entire context
+full_fingerprint = context.fingerprint()
+print(full_fingerprint) # Deterministic hash
+
+# Get fingerprint of specific keys only
+user_fingerprint = context.fingerprint(include=["user.name"])
+print(user_fingerprint) # Hash based only on user.name
+```
+
+## Advanced Usage Patterns
+
+### Custom Context Implementation
+
+```python
+from intent_kit.core.context import ContextProtocol, ContextPatch, LoggerLike
+from typing import Any, Iterable, Mapping, Optional
+import json
+
+class DatabaseContext(ContextProtocol):
+ def __init__(self, db_connection):
+ self.db = db_connection
+ self._cache = {}
+ self._logger = CustomLogger()
+
+ def get(self, key: str, default: Any = None) -> Any:
+ if key in self._cache:
+ return self._cache[key]
+
+ # Query database
+ value = self.db.query(f"SELECT value FROM context WHERE key = ?", (key,))
+ if value:
+ self._cache[key] = value
+ return value
+ return default
+
+ def set(self, key: str, value: Any, modified_by: Optional[str] = None) -> None:
+ self._cache[key] = value
+ self.db.execute(
+ "INSERT OR REPLACE INTO context (key, value, modified_by) VALUES (?, ?, ?)",
+ (key, json.dumps(value), modified_by)
+ )
+
+ def has(self, key: str) -> bool:
+ return self.get(key) is not None
+
+ def keys(self) -> Iterable[str]:
+ return [row[0] for row in self.db.query("SELECT key FROM context")]
+
+ def snapshot(self) -> Mapping[str, Any]:
+ return {key: self.get(key) for key in self.keys()}
+
+ def apply_patch(self, patch: ContextPatch) -> None:
+ for key, value in patch["data"].items():
+ self.set(key, value, patch["provenance"])
+
+ def merge_from(self, other: Mapping[str, Any]) -> None:
+ for key, value in other.items():
+ self.set(key, value)
+
+ def fingerprint(self, include: Optional[Iterable[str]] = None) -> str:
+ if include:
+ data = {key: self.get(key) for key in include if self.has(key)}
+ else:
+ data = self.snapshot()
+ return json.dumps(data, sort_keys=True)
+
+ @property
+ def logger(self) -> LoggerLike:
+ return self._logger
+
+ def add_error(self, *, where: str, err: str, meta: Optional[Mapping[str, Any]] = None) -> None:
+ self.logger.error(f"Error in {where}: {err}")
+
+ def track_operation(self, *, name: str, status: str, meta: Optional[Mapping[str, Any]] = None) -> None:
+ self.logger.info(f"Operation {name}: {status}")
+
+class CustomLogger(LoggerLike):
+ def info(self, message: str) -> None:
+ print(f"[INFO] {message}")
+
+ def warning(self, message: str) -> None:
+ print(f"[WARN] {message}")
+
+ def error(self, message: str) -> None:
+ print(f"[ERROR] {message}")
+
+ def debug(self, message: str, colorize_message: bool = True) -> None:
+ print(f"[DEBUG] {message}")
+
+ def critical(self, message: str) -> None:
+ print(f"[CRITICAL] {message}")
+
+ def trace(self, message: str) -> None:
+ print(f"[TRACE] {message}")
+```
+
+### Context Adapters
+
+Intent Kit provides context adapters for common data structures:
+
+```python
+from intent_kit.core.context import DictBackedContext
+
+# Create context backed by a dictionary
+data = {"user.name": "Alice", "session.id": "session_123"}
+context = DictBackedContext(data)
+
+# Context operations work normally
+context.set("preferences.language", "en")
+print(context.get("user.name")) # "Alice"
+```
+
+### Custom Nodes with Context Access
+
+When creating custom nodes, you can access the context directly in the `execute` method:
+
+```python
+from intent_kit.core.types import NodeProtocol, ExecutionResult
+from intent_kit.core.context import ContextProtocol
+
+class CustomMemoryNode(NodeProtocol):
+ def __init__(self, name: str):
+ self.name = name
+
+ def execute(self, user_input: str, ctx: ContextProtocol) -> ExecutionResult:
+ """Execute with direct context access."""
+
+ # Access context directly
+ user_name = ctx.get("user.name")
+ conversation_count = ctx.get("conversation.count", 0)
+
+ # Update context
+ ctx.set("conversation.count", conversation_count + 1)
+
+ # Create response using context
+ if user_name:
+ response = f"Hello {user_name}! This is conversation #{conversation_count + 1}"
+ else:
+ response = f"Hello! This is conversation #{conversation_count + 1}"
+
+ return ExecutionResult(
+ data=response,
+ next_edges=["success"],
+ terminate=False,
+ context_patch={
+ "last_greeting": response,
+ "greeting_count": conversation_count + 1
+ }
+ )
+
+# Usage in DAG
+builder = DAGBuilder()
+builder.add_node("memory_greeter", CustomMemoryNode("memory_greeter"))
+```
+
+### Action Functions with Context
+
+For action nodes, you can create functions that receive context through the node's execute method:
+
+```python
+from intent_kit.core.context import ContextProtocol
+
+def remember_user_action(name: str, ctx: ContextProtocol) -> str:
+ """Action function that can access context."""
+ # Store in context
+ ctx.set("user.name", name)
+ ctx.set("user.first_seen", time.time())
+
+ return f"Nice to meet you, {name}! I'll remember you."
+
+def weather_with_context_action(location: str, ctx: ContextProtocol) -> str:
+ """Action function that uses context for personalization."""
+ user_name = ctx.get("user.name", "there")
+ weather_count = ctx.get("weather.requests", 0) + 1
+
+ # Update context
+ ctx.set("weather.requests", weather_count)
+ ctx.set("weather.last_location", location)
+
+ return f"Hey {user_name}! The weather in {location} is sunny. (Request #{weather_count})"
+
+## Current Limitations and Workarounds
+
+### Action Function Context Access
+
+In the current implementation, action functions receive parameters but not the context directly:
+
+```python
+def weather_action(location: str, **kwargs) -> str:
+ """Action function - receives parameters but not context."""
+ # This function cannot access context directly
+ return f"The weather in {location} is sunny."
+```
+
+The context is managed by the traversal engine and accessed through context patches returned by the node's execute method.
+
+### Context Persistence Challenges
+
+The current system has some limitations for true context persistence:
+
+1. **Extractor Overwriting**: Each extractor node overwrites the `extracted_params` key
+2. **Action Function Isolation**: Action functions don't have direct context access
+3. **Context Patch Management**: Data must be explicitly stored via context patches
+
+### Workarounds for Context Persistence
+
+To achieve true context persistence, you can:
+
+1. **Use Custom Nodes**: Create custom node implementations that have direct context access
+2. **Leverage Context Patches**: Use context patches to store persistent data
+3. **Use Different Context Keys**: Store persistent data in different context keys than `extracted_params`
+
+### Example: Custom Node with Context Access
+
+```python
+from intent_kit.core.types import NodeProtocol, ExecutionResult
+from intent_kit.core.context import ContextProtocol
+
+class PersistentMemoryNode(NodeProtocol):
+ def __init__(self, name: str):
+ self.name = name
+
+ def execute(self, user_input: str, ctx: ContextProtocol) -> ExecutionResult:
+ """Execute with direct context access."""
+
+ # Get current parameters
+ params = ctx.get("extracted_params", {})
+
+ # Store name persistently if extracted
+ if "name" in params:
+ ctx.set("user.name", params["name"])
+ ctx.set("user.first_seen", time.time())
+
+ # Get remembered name for response
+ user_name = ctx.get("user.name", "there")
+
+ result = f"Hello {user_name}! Nice to meet you."
+
+ return ExecutionResult(
+ data=result,
+ next_edges=["success"],
+ terminate=True,
+ context_patch={
+ "action_result": result,
+ "user.name": params.get("name"), # Store in context patch
+ "user.first_seen": time.time()
+ }
+ )
+```
+
+**Note**: Custom nodes require modifications to the traversal system to be supported.
+```
+
+### Error Handling and Tracking
+
+```python
+from intent_kit.core.context import DefaultContext
+
+context = DefaultContext()
+
+# Track operations
+context.track_operation(name="api_call", status="started", meta={"endpoint": "/users"})
+
+try:
+ # Simulate API call
+ result = api_client.get_user("alice")
+ context.set("user.data", result)
+ context.track_operation(name="api_call", status="completed")
+except Exception as e:
+ # Track errors
+ context.add_error(
+ where="api_call",
+ err=str(e),
+ meta={"endpoint": "/users", "user_id": "alice"}
+ )
+ context.track_operation(name="api_call", status="failed")
+```
+
+## Best Practices
+
+### 1. Use Descriptive Keys
+
+```python
+# Good - descriptive and hierarchical
+context.set("user.profile.name", "Alice")
+context.set("user.profile.email", "alice@example.com")
+context.set("session.current.id", "session_123")
+
+# Avoid - flat and unclear
+context.set("name", "Alice")
+context.set("email", "alice@example.com")
+context.set("session", "session_123")
+```
+
+### 2. Leverage Merge Policies
+
+```python
+# Use appropriate policies for different data types
+patch: ContextPatch = {
+ "data": {
+ "user.name": "Alice", # Use last_write_wins for single values
+ "conversation.history": ["New message"], # Use append_list for lists
+ "user.preferences": {"theme": "dark"} # Use merge_dict for objects
+ },
+ "policy": {
+ "user.name": "last_write_wins",
+ "conversation.history": "append_list",
+ "user.preferences": "merge_dict"
+ },
+ "provenance": "user_interaction"
+}
+```
+
+### 3. Control Memoization
+
+```python
+# Use tags to control memoization behavior
+patch: ContextPatch = {
+ "data": {"user.name": "Alice"},
+ "provenance": "user_extraction",
+ "tags": {"affects_memo"} # This change affects memoization
+}
+
+# Changes without this tag won't affect memoization
+patch2: ContextPatch = {
+ "data": {"debug.enabled": True},
+ "provenance": "debug_setting"
+ # No tags - won't affect memoization
+}
+```
+
+### 4. Track Provenance
+
+```python
+# Always include provenance for auditability
+context.set("user.name", "Alice", modified_by="user_extraction_node")
+context.set("session.id", "session_123", modified_by="session_manager")
+
+# Or use patches with provenance
+patch: ContextPatch = {
+ "data": {"user.name": "Alice"},
+ "provenance": "user_extraction_node"
+}
+```
+
+### 5. Use Fingerprinting for Caching
+
+```python
+# Create cache key based on relevant context
+cache_key = context.fingerprint(include=["user.name", "session.id"])
+
+# Use in memoization
+if cache_key in memo_cache:
+ return memo_cache[cache_key]
+```
+
+## Integration with DAG Traversal
+
+The context system integrates seamlessly with DAG traversal:
+
+```python
+from intent_kit import DAGBuilder, DefaultContext
+
+# Create DAG with context-aware nodes
+builder = DAGBuilder()
+builder.add_node("extract_user", "extractor", ...)
+builder.add_node("greet_user", "action", ...)
+
+dag = builder.build()
+
+# Execute with context
+context = DefaultContext()
+context.set("session.id", "session_123")
+
+result, final_context = dag.execute("Hello Alice", context)
+
+# Context is automatically updated during traversal
+print(final_context.get("user.name")) # "Alice"
+print(final_context.get("greeting.count")) # 1
+```
+
+## Performance Considerations
+
+### 1. Efficient Fingerprinting
+
+```python
+# Only fingerprint relevant keys for memoization
+relevant_keys = ["user.name", "session.id", "preferences.language"]
+fingerprint = context.fingerprint(include=relevant_keys)
+```
+
+### 2. Batch Operations
+
+```python
+# Use patches for multiple changes
+patch: ContextPatch = {
+ "data": {
+ "user.name": "Alice",
+ "user.email": "alice@example.com",
+ "user.preferences": {"language": "en"}
+ },
+ "provenance": "user_registration"
+}
+context.apply_patch(patch)
+```
+
+### 3. Caching Strategies
+
+```python
+# Cache frequently accessed values
+class CachedContext(DefaultContext):
+ def __init__(self):
+ super().__init__()
+ self._cache = {}
+
+ def get(self, key: str, default: Any = None) -> Any:
+ if key in self._cache:
+ return self._cache[key]
+
+ value = super().get(key, default)
+ self._cache[key] = value
+ return value
+```
+
+## Context Read/Write Configuration
+
+Intent Kit provides a declarative approach to context management through node-level configuration. Nodes can specify which context keys they read from and write to, enabling clear data flow and preventing unintended context modifications.
+
+### Node-Level Context Declaration
+
+All node types support context read/write configuration:
+
+```python
+from intent_kit.nodes import ActionNode, ClassifierNode, ExtractorNode
+
+# Action node with context read/write
+action_node = ActionNode(
+ name="weather_action",
+ action=get_weather,
+ context_read=["user.name", "user.preferences"], # Read these keys
+ context_write=["weather.requests", "weather.last_location"], # Write these keys
+ description="Get weather with user context"
+)
+
+# Classifier node with context awareness
+classifier_node = ClassifierNode(
+ name="intent_classifier",
+ output_labels=["greet", "weather", "help"],
+ context_read=["user.name", "conversation.history"], # Read context for classification
+ context_write=["intent.confidence"], # Write classification confidence
+ description="Classify intent with user context"
+)
+
+# Extractor node with context persistence
+extractor_node = ExtractorNode(
+ name="name_extractor",
+ param_schema={"name": str},
+ context_read=["conversation.context"], # Read conversation context
+ context_write=["extraction.confidence"], # Write extraction confidence
+ description="Extract name with context"
+)
+```
+
+### Parameter Key Configuration
+
+Action nodes can specify which parameter keys to check for parameters, enabling flexible parameter sourcing:
+
+```python
+# Action node with custom parameter keys
+action_node = ActionNode(
+ name="weather_action",
+ action=get_weather,
+ param_keys=["location_params", "extracted_params"], # Check these keys for parameters
+ context_read=["user.name"], # Read user name from context
+ context_write=["weather.requests"], # Write request count
+ description="Get weather for location"
+)
+```
+
+### Context-Aware Action Functions
+
+Action functions receive context data through the `**kwargs` parameter:
+
+```python
+def get_weather(location: str, **kwargs) -> str:
+ """Get weather with context awareness."""
+ # Access context data
+ user_name = kwargs.get('user.name')
+ preferences = kwargs.get('user.preferences', {})
+ temperature_unit = preferences.get('temperature_unit', 'fahrenheit')
+
+ if user_name:
+ return f"Hey {user_name}! The weather in {location} is sunny and 72°{temperature_unit[0].upper()}."
+ else:
+ return f"The weather in {location} is sunny and 72°{temperature_unit[0].upper()}."
+
+def remember_name(name: str, **kwargs) -> str:
+ """Remember user name with context."""
+ # Context data is automatically available
+ user_name = kwargs.get('user.name')
+ if user_name:
+ return f"Nice to see you again, {user_name}!"
+ else:
+ return f"Nice to meet you, {name}! I'll remember your name."
+```
+
+### Context Persistence Patterns
+
+#### 1. User Information Persistence
+
+```python
+# Extract and store user information
+builder.add_node(
+ "extract_name",
+ "extractor",
+ param_schema={"name": str},
+ output_key="name_params", # Use specific key to avoid conflicts
+ context_write=["user.name", "user.first_seen"], # Write to persistent context
+ description="Extract and store user name"
+)
+
+# Use stored user information
+builder.add_node(
+ "greet_user",
+ "action",
+ action=greet_user,
+ context_read=["user.name"], # Read stored user name
+ context_write=["greeting.count"], # Track greeting count
+ description="Greet user with stored name"
+)
+```
+
+#### 2. Conversation State Tracking
+
+```python
+# Track conversation state
+builder.add_node(
+ "classify_intent",
+ "classifier",
+ output_labels=["greet", "weather", "help"],
+ context_read=["conversation.turn_count", "user.name"], # Read conversation state
+ context_write=["intent.confidence", "conversation.turn_count"], # Update state
+ description="Classify intent with conversation context"
+)
+```
+
+#### 3. Request Counting and Analytics
+
+```python
+# Track request patterns
+builder.add_node(
+ "weather_action",
+ "action",
+ action=get_weather,
+ context_read=["user.name", "weather.requests"], # Read user and request count
+ context_write=["weather.requests", "weather.last_location", "weather.last_request_time"], # Update analytics
+ description="Get weather with analytics tracking"
+)
+```
+
+### Benefits of Declarative Context Management
+
+1. **Clear Data Flow**: Explicit declaration of what data nodes read and write
+2. **Prevent Conflicts**: Avoid accidental overwrites of important context data
+3. **Audit Trail**: Clear tracking of context modifications
+4. **Performance**: Optimized context access patterns
+5. **Maintainability**: Self-documenting context usage
+
+### Best Practices
+
+1. **Use Descriptive Key Names**: Use hierarchical keys like `user.name`, `weather.requests`
+2. **Minimize Context Reads**: Only read the context keys you actually need
+3. **Be Specific with Writes**: Only write to context keys that are part of your node's responsibility
+4. **Use Parameter Keys**: Use specific parameter keys to avoid conflicts between extractors
+5. **Document Context Usage**: Include context read/write in node descriptions
+
+The context management system provides a robust foundation for building stateful, auditable, and performant intent classification systems with clear data flow and declarative context management.

+# DAG Validation
+
+Intent Kit provides comprehensive DAG validation to ensure correctness, completeness, and optimal performance of intent classification workflows.
+
+## Overview
+
+DAG validation checks for:
+
+- **Structural Integrity** - All nodes and edges are properly connected
+- **Cyclic Dependencies** - No cycles in the graph structure
+- **Reachability** - All nodes are accessible from entrypoints
+- **Label Consistency** - Edge labels match node capabilities
+- **Configuration Validity** - Node configurations are correct
+
+## Validation Functions
+
+### validate_dag_structure
+
+The primary validation function that performs comprehensive DAG analysis:
+
+```python
+from intent_kit.core.validation import validate_dag_structure
+
+# Basic validation
+issues = validate_dag_structure(dag)
+
+if issues:
+ print("Validation issues found:")
+ for issue in issues:
+ print(f" - {issue}")
+else:
+ print("DAG structure is valid")
+```
+
+**Parameters:**
+- `dag` (IntentDAG): The DAG to validate
+- `producer_labels` (Dict[str, Set[str]], optional): Dictionary mapping node_id to set of labels it can produce
+
+**Returns:**
+- `List[str]`: List of validation issues (empty if all valid)
+
+**Raises:**
+- `CycleError`: If a cycle is detected in the DAG
+- `ValueError`: If basic structure is invalid
+
+## Validation Checks
+
+### 1. ID Consistency
+
+Ensures all referenced node IDs exist in the DAG:
+
+```python
+# Valid DAG
+dag = DAGBuilder()
+dag.add_node("classifier", "classifier", ...)
+dag.add_node("extractor", "extractor", ...)
+dag.add_edge("classifier", "extractor", "success") # Both nodes exist
+
+# Invalid DAG - missing node
+dag.add_edge("classifier", "missing_node", "error") # Will fail validation
+```
+
+**Common Issues:**
+- Edge source node doesn't exist
+- Edge destination node doesn't exist
+- Entrypoint node doesn't exist
+
+### 2. Entrypoint Validation
+
+Ensures DAG has valid entrypoints:
+
+```python
+# Valid DAG with entrypoints
+dag = DAGBuilder()
+dag.add_node("classifier", "classifier", ...)
+dag.set_entrypoints(["classifier"])
+
+# Invalid DAG - no entrypoints
+dag = DAGBuilder()
+dag.add_node("classifier", "classifier", ...)
+# Missing set_entrypoints() call - will fail validation
+```
+
+**Requirements:**
+- At least one entrypoint must be defined
+- All entrypoints must exist in the DAG
+- Entrypoints must be reachable
+
+### 3. Cycle Detection
+
+Detects cycles in the DAG structure using Kahn's algorithm:
+
+```python
+# Valid DAG - no cycles
+dag = DAGBuilder()
+dag.add_node("A", "classifier", ...)
+dag.add_node("B", "extractor", ...)
+dag.add_node("C", "action", ...)
+dag.add_edge("A", "B")
+dag.add_edge("B", "C")
+
+# Invalid DAG - cycle detected
+dag.add_edge("C", "A") # Creates cycle A -> B -> C -> A
+```
+
+**Cycle Detection Algorithm:**
+1. Calculate in-degrees for all nodes
+2. Add nodes with zero in-degree to queue
+3. Process queue, reducing in-degrees of neighbors
+4. If all nodes are processed, no cycles exist
+5. If nodes remain unprocessed, cycles exist
+
+### 4. Reachability Analysis
+
+Ensures all nodes are reachable from entrypoints:
+
+```python
+# Valid DAG - all nodes reachable
+dag = DAGBuilder()
+dag.add_node("classifier", "classifier", ...)
+dag.add_node("extractor", "extractor", ...)
+dag.add_node("action", "action", ...)
+dag.add_edge("classifier", "extractor")
+dag.add_edge("extractor", "action")
+dag.set_entrypoints(["classifier"])
+
+# Invalid DAG - unreachable node
+dag.add_node("orphan", "action", ...) # No edges to/from this node
+```
+
+**Reachability Algorithm:**
+1. Start from entrypoints
+2. Traverse edges using BFS
+3. Mark visited nodes
+4. Report unvisited nodes as unreachable
+
+### 5. Label Validation
+
+Validates edge labels against node capabilities (when producer_labels provided):
+
+```python
+from intent_kit.core.validation import validate_dag_structure
+
+# Define node capabilities
+producer_labels = {
+ "classifier": {"greet", "weather", "booking"},
+ "extractor": {"success", "error"},
+ "action": {"success", "error"}
+}
+
+# Validate with label constraints
+issues = validate_dag_structure(dag, producer_labels)
+
+# Valid edges
+dag.add_edge("classifier", "extractor", "greet") # "greet" in classifier labels
+dag.add_edge("extractor", "action", "success") # "success" in extractor labels
+
+# Invalid edge
+dag.add_edge("classifier", "extractor", "invalid_label") # Not in classifier labels
+```
+
+## Error Handling
+
+### Common Exceptions
+
+#### CycleError
+
+Raised when a cycle is detected in the DAG:
+
+```python
+from intent_kit.core.exceptions import CycleError
+
+try:
+ issues = validate_dag_structure(dag)
+except CycleError as e:
+ print(f"Cycle detected: {e}")
+ # Handle cycle - typically requires DAG redesign
+```
+
+#### ValueError
+
+Raised for basic structural issues:
+
+```python
+try:
+ issues = validate_dag_structure(dag)
+except ValueError as e:
+ print(f"Structural error: {e}")
+ # Handle structural issues
+```
+
+### Validation Issue Types
+
+```python
+# Common validation issues
+issues = [
+ "Unreachable nodes: orphan_node",
+ "Missing node: referenced_node",
+ "Invalid entrypoint: non_existent_entrypoint",
+ "Cycle detected: A -> B -> C -> A",
+ "Invalid edge label: 'invalid_label' not in producer labels"
+]
+```
+
+## Advanced Validation
+
+### Custom Validation Rules
+
+Extend validation with custom rules:
+
+```python
+def custom_validation(dag):
+ issues = []
+
+ # Check for required node types
+ has_classifier = any(node.type == "classifier" for node in dag.nodes.values())
+ if not has_classifier:
+ issues.append("DAG must contain at least one classifier node")
+
+ # Check for proper error handling
+ has_clarification = any(node.type == "clarification" for node in dag.nodes.values())
+ if not has_clarification:
+ issues.append("Consider adding clarification nodes for error handling")
+
+ return issues
+
+# Combine with built-in validation
+builtin_issues = validate_dag_structure(dag)
+custom_issues = custom_validation(dag)
+all_issues = builtin_issues + custom_issues
+```
+
+### Performance Validation
+
+Validate DAG performance characteristics:
+
+```python
+def performance_validation(dag):
+ issues = []
+
+ # Check for excessive fanout
+ for node_id, node in dag.nodes.items():
+ outgoing_edges = len(dag.adj.get(node_id, {}))
+ if outgoing_edges > 10:
+ issues.append(f"Node {node_id} has high fanout ({outgoing_edges} edges)")
+
+ # Check for deep chains
+ max_depth = calculate_max_depth(dag)
+ if max_depth > 20:
+ issues.append(f"DAG has deep execution chain ({max_depth} levels)")
+
+ return issues
+
+def calculate_max_depth(dag):
+ """Calculate maximum depth from entrypoints to any node."""
+ depths = {}
+
+ def dfs(node_id, depth):
+ if node_id in depths:
+ depths[node_id] = max(depths[node_id], depth)
+ else:
+ depths[node_id] = depth
+
+ for labels in dag.adj.get(node_id, {}).values():
+ for next_node in labels:
+ dfs(next_node, depth + 1)
+
+ for entrypoint in dag.entrypoints:
+ dfs(entrypoint, 0)
+
+ return max(depths.values()) if depths else 0
+```
+
+## Integration with DAG Building
+
+### Automatic Validation
+
+DAG validation is automatically performed during build:
+
+```python
+from intent_kit import DAGBuilder
+
+builder = DAGBuilder()
+
+# Add nodes and edges
+builder.add_node("classifier", "classifier", ...)
+builder.add_node("extractor", "extractor", ...)
+builder.add_edge("classifier", "extractor", "success")
+
+# Build with validation (default)
+dag = builder.build() # Validates automatically
+
+# Build without validation (not recommended)
+dag = builder.build(validate_structure=False)
+```
+
+### Validation During Development
+
+Use validation during DAG development:
+
+```python
+# Validate after each major change
+builder = DAGBuilder()
+builder.add_node("classifier", "classifier", ...)
+
+# Check intermediate state
+try:
+ dag = builder.build()
+ print("DAG is valid so far")
+except Exception as e:
+ print(f"Validation failed: {e}")
+
+# Continue building
+builder.add_node("extractor", "extractor", ...)
+builder.add_edge("classifier", "extractor", "success")
+
+# Final validation
+dag = builder.build()
+print("DAG is complete and valid")
+```
+
+## Best Practices
+
+### 1. Start with Simple DAGs
+
+```python
+# Start simple and add complexity
+builder = DAGBuilder()
+
+# Phase 1: Basic classifier -> action
+builder.add_node("classifier", "classifier", ...)
+builder.add_node("action", "action", ...)
+builder.add_edge("classifier", "action", "success")
+dag = builder.build() # Validate
+
+# Phase 2: Add extractor
+builder.add_node("extractor", "extractor", ...)
+builder.add_edge("classifier", "extractor", "success")
+builder.add_edge("extractor", "action", "success")
+dag = builder.build() # Validate
+
+# Phase 3: Add error handling
+builder.add_node("clarification", "clarification", ...)
+builder.add_edge("classifier", "clarification", "error")
+builder.add_edge("extractor", "clarification", "error")
+dag = builder.build() # Validate
+```
+
+### 2. Use Descriptive Node Names
+
+```python
+# Good - descriptive names
+builder.add_node("intent_classifier", "classifier", ...)
+builder.add_node("extract_user_name", "extractor", ...)
+builder.add_node("send_greeting", "action", ...)
+
+# Avoid - unclear names
+builder.add_node("node1", "classifier", ...)
+builder.add_node("node2", "extractor", ...)
+builder.add_node("node3", "action", ...)
+```
+
+### 3. Validate Early and Often
+
+```python
+# Validate at each step
+builder = DAGBuilder()
+
+# Step 1: Add classifier
+builder.add_node("classifier", "classifier", ...)
+try:
+ dag = builder.build()
+ print("✓ Classifier added successfully")
+except Exception as e:
+ print(f"✗ Classifier validation failed: {e}")
+ return
+
+# Step 2: Add extractor
+builder.add_node("extractor", "extractor", ...)
+builder.add_edge("classifier", "extractor", "success")
+try:
+ dag = builder.build()
+ print("✓ Extractor added successfully")
+except Exception as e:
+ print(f"✗ Extractor validation failed: {e}")
+ return
+```
+
+### 4. Handle Validation Errors Gracefully
+
+```python
+def build_dag_with_validation():
+ builder = DAGBuilder()
+
+ try:
+ # Build DAG
+ builder.add_node("classifier", "classifier", ...)
+ builder.add_node("extractor", "extractor", ...)
+ builder.add_edge("classifier", "extractor", "success")
+
+ # Validate and build
+ dag = builder.build()
+ print("DAG built successfully")
+ return dag
+
+ except CycleError as e:
+ print(f"Cycle detected: {e}")
+ print("Please review your DAG structure")
+ return None
+
+ except ValueError as e:
+ print(f"Structural error: {e}")
+ print("Please check node IDs and connections")
+ return None
+
+ except Exception as e:
+ print(f"Unexpected error: {e}")
+ return None
+```
+
+### 5. Use Label Constraints
+
+```python
+# Define clear label constraints
+producer_labels = {
+ "intent_classifier": {"greet", "weather", "booking", "help"},
+ "user_extractor": {"success", "missing_name", "invalid_format"},

+}
+
+# Validate with constraints
+issues = validate_dag_structure(dag, producer_labels)
+if issues:
+ print("Label validation issues:")
+ for issue in issues:
+ print(f" - {issue}")
+```
+
+## Performance Considerations
+
+### 1. Validation Overhead
+
+```python
+# Validation adds overhead - use judiciously
+import time
+
+# Time validation
+start = time.time()
+issues = validate_dag_structure(dag)
+validation_time = time.time() - start
+
+print(f"Validation took {validation_time:.3f} seconds")
+
+# For large DAGs, consider validation levels
+if dag_size < 100:
+ # Full validation for small DAGs
+ issues = validate_dag_structure(dag)
+else:
+ # Basic validation for large DAGs
+ issues = validate_dag_structure(dag, producer_labels=None)
+```
+
+### 2. Caching Validation Results
+
+```python
+# Cache validation results for unchanged DAGs
+class CachedDAG:
+ def __init__(self, dag):
+ self.dag = dag
+ self._validation_cache = None
+ self._dag_hash = None
+
+ def validate(self):
+ current_hash = hash(str(self.dag.nodes) + str(self.dag.adj))
+
+ if self._dag_hash == current_hash and self._validation_cache is not None:
+ return self._validation_cache
+
+ issues = validate_dag_structure(self.dag)
+ self._validation_cache = issues
+ self._dag_hash = current_hash
+ return issues
+```
+
+DAG validation ensures your intent classification workflows are robust, efficient, and maintainable.

+# Extractor Nodes
+
+Extractor nodes are powerful components in Intent Kit that use LLM services to extract structured parameters from user input. They provide intelligent parameter extraction with type validation and error handling.
+
+## Overview
+
+Extractor nodes:
+- Use LLM services to understand and extract parameters from natural language
+- Support type validation and coercion
+- Provide structured output with extracted parameters
+- Handle edge cases and missing parameters gracefully
+- Track token usage and costs
+
+## Basic Usage
+
+```python
+from intent_kit import DAGBuilder
+
+# Add to DAG
+builder = DAGBuilder()
+builder.add_node("extract_booking", "extractor",
+ param_schema={
+ "date": str,
+ "time": str,
+ "guests": int,
+ "restaurant": str
+ },
+ description="Extract booking parameters",
+ output_key="booking_params")
+```
+
+## Parameter Schema
+
+The `param_schema` defines the structure and types of parameters to extract:
+
+```python
+param_schema = {
+ "name": str, # String parameter
+ "age": int, # Integer parameter
+ "price": float, # Float parameter
+ "is_active": bool, # Boolean parameter
+ "tags": list, # List parameter
+ "metadata": dict # Dictionary parameter
+}
+```
+
+### Type Validation
+
+Extractor nodes automatically validate and coerce types:
+
+```python
+# Input: "I want to book for 5 people at 7:30 PM"
+# Output: {"guests": 5, "time": "7:30 PM"}
+
+param_schema = {
+ "guests": int, # Will extract "5" and convert to integer
+ "time": str # Will extract "7:30 PM" as string
+}
+```
+
+## Advanced Configuration
+
+### Custom Prompts
+
+You can provide custom prompts for specific extraction scenarios:
+
+```python
+extractor = ExtractorNode(
+ name="extract_address",
+ param_schema={"street": str, "city": str, "zip": str},
+ custom_prompt="""
+ Extract address components from the user input.
+ Focus on identifying street address, city, and zip code.
+ If any component is missing, use null.
+ """,
+ output_key="address_params"
+)
+```
+
+### LLM Configuration
+
+Configure specific LLM settings for extraction:
+
+```python
+extractor = ExtractorNode(
+ name="extract_complex_params",
+ param_schema={"complex_field": str},
+ llm_config={
+ "provider": "openrouter",
+ "model": "google/gemma-2-9b-it",
+ "temperature": 0.1, # Low temperature for consistent extraction
+ "max_tokens": 500
+ },
+ output_key="complex_params"
+)
+```
+
+## Error Handling
+
+Extractor nodes handle various error scenarios:
+
+### Missing Parameters
+
+```python
+# If a parameter is missing, it will be set to None or default value
+# Input: "Book a table for 4 people" (missing time)
+# Output: {"guests": 4, "time": None}
+```
+
+### Type Conversion Errors
+
+```python
+# If type conversion fails, the node will handle gracefully
+# Input: "Book for abc people" (invalid number)
+# Output: {"guests": None} with error in context
+```
+
+### LLM Service Errors
+
+```python
+# If LLM service is unavailable, the node will raise appropriate exceptions
+# with detailed error information
+```
+
+## Context Integration
+
+Extracted parameters are stored in the execution context:
+
+```python
+# After extraction, parameters are available in context
+context = DefaultContext()
+result = dag.execute("Book a table for 4 people at 7 PM", context)
+
+# Access extracted parameters
+booking_params = context.get("booking_params")
+print(booking_params) # {"guests": 4, "time": "7 PM"}
+```
+
+## Performance Monitoring
+
+Extractor nodes track performance metrics:
+
+```python
+# Metrics are available in the execution result
+result = extractor.execute("Book a table for 4 people", context)
+
+print(result.metrics)
+# {
+# "input_tokens": 15,
+# "output_tokens": 45,
+# "cost": 0.0023,
+# "duration": 1.2
+# }
+```
+
+## Best Practices
+
+### 1. Clear Parameter Names
+
+```python
+# Good: Clear, descriptive parameter names
+param_schema = {
+ "reservation_date": str,
+ "party_size": int,
+ "preferred_time": str
+}
+
+# Avoid: Vague parameter names
+param_schema = {
+ "date": str,
+ "size": int,
+ "time": str
+}
+```
+
+### 2. Appropriate Type Definitions
+
+```python
+# Use specific types when possible
+param_schema = {
+ "price": float, # Use float for monetary values
+ "quantity": int, # Use int for counts
+ "is_confirmed": bool, # Use bool for flags
+ "notes": str # Use str for text
+}
+```
+
+### 3. Descriptive Prompts
+
+```python
+# Provide clear, specific prompts
+custom_prompt = """
+Extract booking information from the user's request.
+- reservation_date: The date for the reservation (YYYY-MM-DD format)
+- party_size: Number of people (integer)
+- preferred_time: Preferred time (HH:MM format)
+- special_requests: Any special requirements or requests
+"""
+```
+
+### 4. Error Handling
+
+```python
+# Always handle missing or invalid parameters
+def process_booking(context):
+ params = context.get("booking_params", {})
+
+ if not params.get("party_size"):
+ return "How many people will be in your party?"
+
+ if not params.get("reservation_date"):
+ return "What date would you like to make the reservation for?"
+
+ # Process valid booking
+ return f"Booking confirmed for {params['party_size']} people on {params['reservation_date']}"
+```
+
+## Integration with Other Nodes
+
+### With Classifier Nodes
+
+```python
+# Classifier routes to appropriate extractor
+builder.add_edge("intent_classifier", "booking_extractor", "make_booking")
+builder.add_edge("intent_classifier", "flight_extractor", "book_flight")
+```
+
+### With Action Nodes
+
+```python
+# Extractor provides parameters to action
+builder.add_edge("booking_extractor", "create_booking_action", "success")
+```
+
+### With Clarification Nodes
+
+```python
+# Extractor can route to clarification if parameters are unclear
+builder.add_edge("booking_extractor", "booking_clarification", "missing_params")
+```
+
+## Examples
+
+### Restaurant Booking
+
+```python
+builder.add_node("extract_booking", "extractor",
+ param_schema={
+ "restaurant": str,
+ "date": str,
+ "time": str,
+ "party_size": int,
+ "special_requests": str
+ },
+ description="Extract restaurant booking parameters",
+ custom_prompt="""
+ Extract restaurant booking information:
+ - restaurant: Name of the restaurant
+ - date: Reservation date (YYYY-MM-DD)
+ - time: Preferred time (HH:MM)
+ - party_size: Number of people
+ - special_requests: Any special requirements
+ """,
+ output_key="booking_params")
+```
+
+### Flight Booking
+
+```python
+builder.add_node("extract_flight", "extractor",
+ param_schema={
+ "origin": str,
+ "destination": str,
+ "departure_date": str,
+ "return_date": str,
+ "passengers": int,
+ "class": str
+ },
+ description="Extract flight booking parameters",
+ output_key="flight_params")
+```
+
+### Product Search
+
+```python
+builder.add_node("extract_search", "extractor",
+ param_schema={
+ "product": str,
+ "category": str,
+ "min_price": float,
+ "max_price": float,
+ "brand": str
+ },
+ description="Extract product search parameters",
+ output_key="search_params")
+```

# Intent DAGs
-Intent DAGs (Directed Acyclic Graphs) are the core architectural concept in Intent Kit. They provide a flexible, scalable way to route user input through a series of nodes to produce structured outputs.
+Intent DAGs (Directed Acyclic Graphs) are the core architectural concept in Intent Kit. They provide a flexible, scalable way to route user input through a series of nodes to produce structured outputs with support for node reuse and complex routing patterns.
## Overview
An intent DAG is a directed acyclic graph where:
-- **Nodes** represent decision points, extractors, or actions
+- **Nodes** represent decision points, extractors, actions, or clarification points
- **Edges** represent the flow between nodes with optional labels
-- **Entrypoints** are starting nodes for user input
+- **Entrypoints** are starting nodes for user input processing
- **Actions** are terminal nodes that produce outputs
+- **Node Reuse** allows nodes to be shared across multiple execution paths
## DAG Structure
```text
User Input → Classifier → Extractor → Action → Output
- ↓
- Clarification
+ ↓ ↓
+ Clarification Shared Extractor
+ ↓ ↓
+ Action Action
```
+### Key DAG Features
+
+1. **Node Reuse** - Nodes can have multiple parents and children, enabling efficient sharing
+2. **Flexible Routing** - Complex routing patterns with conditional edges
+3. **Parallel Execution** - Multiple paths can be executed simultaneously
+4. **Context Propagation** - Rich context flows through all execution paths
+

+Define DAGs using JSON configuration:
+- **Declarative Workflows** - Define complete DAGs in JSON
+- **Function References** - Reference Python functions directly
+- **Portable Configurations** - Share and version workflows
+- **Advanced Patterns** - Complex routing and node reuse
+
+## Quick Configuration Guide
+
+### Basic Setup
+
+```python
+from intent_kit import DAGBuilder
+
+# Set default LLM configuration
+builder = DAGBuilder()
+builder.with_default_llm_config({
+ "provider": "openrouter",
+ "model": "google/gemma-2-9b-it",
+ "api_key": "your-api-key"
+})
+```
+
+### Environment Variables
+
+```bash
+# OpenAI
+export OPENAI_API_KEY="your-openai-key"
+
+# Anthropic
+export ANTHROPIC_API_KEY="your-anthropic-key"
+
+# Google
+export GOOGLE_API_KEY="your-google-key"
+
+# OpenRouter
+export OPENROUTER_API_KEY="your-openrouter-key"
+
+# Ollama
+export OLLAMA_BASE_URL="http://localhost:11434"
+```
+
+### JSON Configuration
+
+```python
+# Define DAG in JSON
+dag_config = {
+ "nodes": {
+ "classifier": {
+ "type": "classifier",
+ "output_labels": ["greet", "weather"],
+ "description": "Main intent classifier"
+ }
+ },
+ "edges": [
+ {"from": "classifier", "to": "greet_action", "label": "greet"}
+ ],
+ "entrypoints": ["classifier"]
+}
+
+# Build from JSON
+dag = DAGBuilder.from_json(dag_config)
+```
+
+## Configuration Best Practices
+
+### 1. **Environment-Specific Configurations**
+
+```python
+import os
+
+def get_llm_config():
+ env = os.getenv("ENVIRONMENT", "development")
+
+ if env == "production":
+ return {
+ "provider": "openai",
+ "model": "gpt-4o",
+ "temperature": 0.1
+ }
+ elif env == "development":
+ return {
+ "provider": "ollama",
+ "model": "llama2",
+ "temperature": 0.7
+ }
+ else:
+ return {
+ "provider": "openrouter",
+ "model": "google/gemma-2-9b-it",
+ "temperature": 0.5
+ }
+```
+
+### 2. **Cost Optimization**
+
+```python
+# Use appropriate models for different tasks
+task_configs = {
+ "classification": {
+ "provider": "openrouter",
+ "model": "google/gemma-2-9b-it", # Fast, cheap
+ "temperature": 0.1
+ },
+ "extraction": {
+ "provider": "openai",
+ "model": "gpt-4o", # Accurate extraction
+ "temperature": 0.0
+ },
+ "conversation": {
+ "provider": "anthropic",
+ "model": "claude-3-7-sonnet-20250219", # Good balance
+ "temperature": 0.7
+ }
+}
+```
+
+### 3. **Security Considerations**
+
+```python
+# Never hardcode API keys
+llm_config = {
+ "provider": "openai",
+ "model": "gpt-4o",
+ "api_key": os.getenv("OPENAI_API_KEY") # Use environment variables
+}
+
+# Validate configuration
+def validate_config(config):
+ required_keys = ["provider", "model", "api_key"]
+ for key in required_keys:
+ if key not in config or not config[key]:
+ raise ValueError(f"Missing required configuration: {key}")
+```
+
+### 4. **Performance Tuning**
+
+```python
+# Optimize for your use case
+performance_config = {
+ "provider": "openrouter",
+ "model": "google/gemma-2-9b-it",
+ "temperature": 0.1,
+ "max_tokens": 100, # Limit response length
+ "timeout": 30, # Set reasonable timeout
+ "retries": 3 # Handle transient failures
+}
+```
+
+## Configuration Validation
+
+### Schema Validation
+
+```python
+from intent_kit.core.validation import validate_dag_config
+
+# Validate your configuration
+try:
+ validate_dag_config(dag_config)
+ print("Configuration is valid!")
+except ValueError as e:
+ print(f"Configuration error: {e}")
+```
+
+### Runtime Validation
+
+```python
+# Test configuration at runtime
+def test_configuration(dag_config):
+ try:
+ dag = DAGBuilder.from_json(dag_config)
+ result = dag.execute("test input")
+ print("Configuration works correctly!")
+ return True
+ except Exception as e:
+ print(f"Configuration test failed: {e}")
+ return False
+```
+
+## Migration Guide
+
+### Updating Configurations
+
+When updating Intent Kit versions, you may need to update your configurations:
+
+1. **Check the changelog** for breaking changes
+2. **Test configurations** in a development environment
+3. **Update gradually** to minimize risk
+4. **Monitor performance** after updates
+
+### Version Compatibility
+
+```python
+# Check version compatibility
+import intent_kit
+
+print(f"Intent Kit version: {intent_kit.__version__}")
+
+# Use version-specific configurations
+if intent_kit.__version__.startswith("0.6"):
+ # Use DAG-based configuration
+ config = dag_based_config()
+else:
+ # Use legacy configuration
+ config = legacy_config()
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **API Key Errors**
+ - Verify environment variables are set
+ - Check API key permissions
+ - Ensure provider is supported
+
+2. **Model Not Found**
+ - Verify model names are correct
+ - Check provider-specific model availability
+ - Use fallback models when needed
+
+3. **Configuration Errors**
+ - Validate JSON syntax
+ - Check required fields
+ - Verify function references
+
+### Debug Configuration
+
+```python
+import logging
+
+# Enable debug logging
+logging.basicConfig(level=logging.DEBUG)
+
+# Test configuration step by step
+def debug_configuration(dag_config):
+ print("Testing configuration...")
+
+ # Test JSON parsing
+ print("✓ JSON is valid")
+
+ # Test node creation
+ print("✓ Nodes created successfully")
+
+ # Test edge validation
+ print("✓ Edges validated")
+
+ # Test DAG building
+ dag = DAGBuilder.from_json(dag_config)
+ print("✓ DAG built successfully")
+
+ return dag
+```

+# Evaluation Framework
+
+Intent Kit provides a comprehensive evaluation framework for testing and benchmarking nodes against structured datasets. This framework enables systematic testing of node performance, accuracy, and reliability.
+
+## Overview
+
+The evaluation framework includes:
+- **Structured Datasets** - YAML-based test case definitions
+- **Comprehensive Metrics** - Accuracy, performance, and cost tracking
+- **Automated Testing** - Batch evaluation of multiple test cases
+- **Report Generation** - Detailed performance reports and analysis
+- **Regression Testing** - Track performance changes over time
+
+## Basic Usage
+
+### Running Evaluations
+
+```python
+from intent_kit.evals import evaluate_node, load_dataset
+
+# Load a dataset
+dataset = load_dataset("path/to/dataset.yaml")
+
+# Evaluate a node
+result = evaluate_node(dataset, node_instance)
+
+# Print results
+result.print_summary()
+print(f"Accuracy: {result.accuracy():.1%}")
+```
+
+### Command Line Interface
+
+```bash
+# Run all evaluations
+uv run python -m intent_kit.evals.run_all_evals
+
+# Run specific node evaluation
+uv run python -m intent_kit.evals.run_node_eval --dataset classifier_node_llm.yaml
+
+# Run with specific configuration
+uv run python -m intent_kit.evals.run_node_eval --dataset extractor_node.yaml --config production.yaml
+```

+
+```python
+def check_regression(current_result, baseline_result, threshold=0.05):
+ """Check if performance has regressed significantly."""
+ current_accuracy = current_result.accuracy()
+ baseline_accuracy = baseline_result.accuracy()
+
+ if current_accuracy < baseline_accuracy - threshold:
+ print(f"⚠️ Performance regression detected!")
+ print(f"Baseline: {baseline_accuracy:.1%}")
+ print(f"Current: {current_accuracy:.1%}")
+ print(f"Regression: {baseline_accuracy - current_accuracy:.1%}")
+ return False
+
+ print(f"✅ No significant regression detected")
+ return True
+```
+
+## Best Practices
+
+### 1. Comprehensive Test Coverage
+
+```yaml
+# Include various input types
+test_cases:
+ # Normal cases
+ - input: "Hello"
+ expected: "greet"
+
+ # Edge cases
+ - input: ""
+ expected: "clarification"
+
+ # Boundary cases
+ - input: "A" * 1000 # Very long input
+ expected: "greet"
+
+ # Special characters
+ - input: "Hello! How are you? 😊"
+ expected: "greet"
+```
+
+### 2. Realistic Test Data
+
+```yaml
+# Use realistic, diverse test data
+test_cases:
+ - input: "Hi there, how's it going?"
+ expected: "greet"
+ context:
+ user_demographic: "casual"
+
+ - input: "Good morning, sir. How may I assist you today?"
+ expected: "greet"
+ context:
+ user_demographic: "formal"
+```
+
+### 3. Performance Benchmarks
+
+```yaml
+# Include performance expectations
+test_cases:
+ - input: "Simple greeting"
+ expected: "greet"
+ context:
+ max_response_time: 1.0
+ max_tokens: 100
+
+ - input: "Complex multi-intent request"
+ expected: "multi_intent"
+ context:
+ max_response_time: 5.0
+ max_tokens: 500
+```
+
+### 4. Regular Evaluation
+
+```bash
+# Set up automated evaluation
+# Add to your CI/CD pipeline
+uv run python -m intent_kit.evals.run_all_evals --output-dir results --format json
+
+# Check for regressions
+python scripts/check_regression.py results/current.json results/baseline.json
+```

## Key Features Demonstrated
-### 1. **Multi-Intent Classification**
+### 1. **Declarative Context Management**
+Nodes explicitly declare their context dependencies:
+- `context_read`: Specifies which context keys to read before execution
+- `context_write`: Specifies which context keys to write after execution
+- `param_keys`: Specifies which parameter keys to check for parameters
+
+### 2. **Context-Aware Action Functions**
+Action functions receive context data through `**kwargs`:
+- Access context values like `kwargs.get('user.name')`
+- Fallback to function parameters if context not available
+- No need for global variables or manual context management
+
+### 3. **Parameter Key Configuration**
+Action nodes can specify multiple parameter sources:
+- `param_keys=["name_params", "extracted_params"]` checks multiple keys
+- Prevents parameter conflicts between different extractors
+- Enables flexible parameter sourcing
+
+### 4. **Context Persistence**
+The bot remembers user information across multiple turns:
+- Names are stored and retrieved using `user.name` context key
+- Weather requests are tracked with `weather.requests` counter
+- Last location is remembered with `weather.last_location`
+
+### 5. **Multi-Intent Classification**
The classifier can handle multiple types of requests:
- Greetings with name introduction
- Weather inquiries
- Memory retrieval requests
-### 2. **Context Persistence**
-The bot remembers user information across multiple turns:
-- Names are stored and retrieved
-- Personalized responses based on remembered data
-
-### 3. **Parameter Extraction**
+### 6. **Parameter Extraction**
Different extractors handle different parameter types:
-- Name extraction from greetings
-- Location extraction from weather requests
+- Name extraction from greetings (stored in `name_params`)
+- Location extraction from weather requests (stored in `location_params`)
-### 4. **Flexible Routing**
+### 7. **Flexible Routing**
The DAG routes to different paths based on classification:
- Greeting → Name extraction → Remember action
- Weather → Location extraction → Weather action
- Memory → Direct memory retrieval action
-### 5. **Error Handling**
+### 8. **Error Handling**
Clarification node handles unclear requests gracefully.
## Advanced Context Features
-### Global Context Management
-This example uses a simple global dictionary, but in production you might:
-- Use a database for persistent storage
-- Implement user session management
-- Add context expiration and cleanup
+### Declarative Context Management
+This example demonstrates Intent Kit's declarative approach to context management:
+- **Explicit Dependencies**: Nodes declare exactly what context they read and write
+- **Clear Data Flow**: Context modifications are visible in node configuration
+- **Prevent Conflicts**: No accidental overwrites of important context data
+- **Self-Documenting**: Context usage is part of the node's configuration
+
+### Context Persistence Patterns
+The demo shows several context persistence patterns:
+- **User Information**: `user.name`, `user.first_seen` for persistent user data
+- **Request Tracking**: `weather.requests` for analytics and counting
+- **State Management**: `weather.last_location` for conversation state
+- **Parameter Isolation**: `name_params`, `location_params` to avoid conflicts
+
+### Context-Aware Functions
+Action functions can access context data seamlessly:
+- **Automatic Injection**: Context data is automatically passed to action functions
+- **Fallback Logic**: Functions can check both context and parameters
+- **Type Safety**: Context values maintain their original types
+- **Error Handling**: Graceful handling of missing context data
+
+### Production Context Management
+In production applications, you might:
+- Use a database for persistent storage across sessions
+- Implement user session management with context isolation
+- Add context expiration and cleanup policies
- Use distributed context storage for scalability
+- Implement context encryption for sensitive data
-### Context Security
+### Context Security and Auditing
The context system provides:
-- Namespace protection for system keys
-- Audit trails for context modifications
-- Type validation for context values
-- Immutable snapshots for debugging
+- **Namespace Protection**: System keys are protected from accidental modification
+- **Audit Trails**: All context modifications are tracked with provenance
+- **Type Validation**: Context values are validated against expected types
+- **Immutable Snapshots**: Context state can be captured for debugging
+- **Access Control**: Fine-grained control over context read/write permissions

+# DAG Examples
+
+This guide provides comprehensive examples of DAG patterns, including node reuse, complex routing, and advanced use cases.
+
+## Overview
+
+DAGs in Intent Kit support:
+- **Node Reuse** - Share nodes across multiple execution paths
+- **Complex Routing** - Conditional logic and branching
+- **Parallel Execution** - Multiple paths executed simultaneously
+- **Context Propagation** - Rich context flows through all paths
+
+## Basic DAG Patterns
+
+### Simple Linear Flow
+
+```python
+from intent_kit import DAGBuilder, run_dag
+from intent_kit.core.context import DefaultContext
+
+def greet(name: str, **kwargs) -> str:
+ return f"Hello {name}!"
+
+def get_weather(city: str, **kwargs) -> str:
+ return f"Weather in {city} is sunny"
+
+# Create DAG
+builder = DAGBuilder()
+builder.with_default_llm_config({
+ "provider": "openrouter",
+ "model": "google/gemma-2-9b-it"
+})
+
+# Add nodes
+builder.add_node("classifier", "classifier",
+ output_labels=["greet", "weather"],
+ description="Route to appropriate action")
+
+builder.add_node("extract_name", "extractor",
+ param_schema={"name": str},
+ description="Extract name from greeting")
+
+builder.add_node("extract_city", "extractor",
+ param_schema={"city": str},
+ description="Extract city from weather request")
+
+builder.add_node("greet_action", "action",
+ action=greet,
+ description="Greet the user")
+
+builder.add_node("weather_action", "action",
+ action=get_weather,
+ description="Get weather information")
+
+# Connect nodes
+builder.add_edge("classifier", "extract_name", "greet")
+builder.add_edge("extract_name", "greet_action", "success")
+builder.add_edge("classifier", "extract_city", "weather")
+builder.add_edge("extract_city", "weather_action", "success")
+
+builder.set_entrypoints(["classifier"])
+
+# Build and execute
+dag = builder.build()
+context = DefaultContext()
+
+result, context = run_dag(dag, "Hello Alice")
+print(result.data) # "Hello Alice!"
+
+result, context = run_dag(dag, "What's the weather in New York?", context)
+print(result.data) # "Weather in New York is sunny"
+```
+
+## Node Reuse Patterns
+
+### Shared Extractor
+
+```python
+from intent_kit import DAGBuilder
+
+def book_flight(origin: str, destination: str, date: str) -> str:

+ return f"Hotel booked in {city} from {check_in} to {check_out}"
+
+# Create DAG with shared extractor
+builder = DAGBuilder()
+
+# Shared location extractor used by multiple paths

+ param_schema={"location": str},
+ description="Extract location information",
+ output_key="location_params")
+
+# Flight booking path
+builder.add_node("flight_classifier", "classifier",
+ output_labels=["book_flight"],
+ description="Classify flight booking requests")
+
+builder.add_node("extract_flight_details", "extractor",

+
+builder.add_node("extract_hotel_details", "extractor",
+ param_schema={"city": str, "check_in": str, "check_out": str},
+ description="Extract hotel details")
+
+builder.add_node("hotel_action", "action",

+
+## Best Practices
+
+### 1. Node Naming
+
+```python
+# Use descriptive, consistent naming
+builder.add_node("user_authentication_classifier", "classifier", ...)
+builder.add_node("extract_user_credentials", "extractor", ...)
+builder.add_node("validate_user_credentials", "action", ...)
+```
+
+### 2. Error Handling
+
+```python
+# Always include error handling paths
+builder.add_node("data_processor", "classifier",
+ output_labels=["success", "error", "retry"],
+ description="Process data with error handling")
+```
+
+### 3. Context Management
+
+```python
+# Use context to pass data between nodes
+context = DefaultContext()
+context.set("user_id", "user123")
+context.set("session_id", "session456")
+
+result = dag.execute("Process my request", context)
+```
+
+### 4. Performance Optimization
+
+```python
+# Use shared nodes for common operations
+builder.add_node("shared_text_processor", "extractor",
+ param_schema={"text": str},
+ description="Shared text processing")
+```
+
+### 5. Testing
+
+```python
+# Test each path in your DAG
+test_cases = [
+ ("Hello Alice", "greet"),
+ ("What's the weather in New York?", "weather"),
+ ("Book a flight to Paris", "booking")
+]
+
+for input_text, expected_intent in test_cases:
+ result = dag.execute(input_text, context)
+ assert result.data is not None
+```

+# JSON Demo
+
+This example demonstrates how to create DAGs using JSON configuration, providing a declarative approach to defining intent workflows.
+
+## Overview
+
+The JSON demo shows how to:
+- Define complete DAGs in JSON format

+
+## Full Example
+
+```python

+## JSON Schema
+
+### DAG Structure
+
+```json
+{
+ "nodes": {
+ "node_id": {
+ "type": "classifier|extractor|action|clarification",
+ "description": "Optional description",
+ // Node-specific configuration
+ }
+ },
+ "edges": [
+ {
+ "from": "source_node_id",
+ "to": "target_node_id",
+ "label": "optional_edge_label"
+ }
+ ],
+ "entrypoints": ["node_id1", "node_id2"]
+}
+```
+
+### Node Types
+
+#### Classifier Node
+```json
+{
+ "type": "classifier",
+ "output_labels": ["label1", "label2", "label3"],
+ "description": "Classify user intent",
+ "llm_config": {
+ "provider": "openai|anthropic|google|ollama|openrouter",
+ "model": "model_name",
+ "api_key": "your_api_key",
+ "temperature": 0.7,
+ "max_tokens": 1000
+ }
+}
+```
+
+#### Extractor Node
+```json
+{
+ "type": "extractor",
+ "param_schema": {
+ "param_name": "str|int|float|bool|list|dict"
+ },
+ "description": "Extract parameters from input",
+ "output_key": "extracted_params",
+ "llm_config": {
+ "provider": "openrouter",
+ "model": "google/gemma-2-9b-it"
+ }
+}
+```
+
+#### Action Node
+```json
+{
+ "type": "action",
+ "action": "function_reference",
+ "description": "Execute action"
+}
+```
+
+#### Clarification Node
+```json
+{
+ "type": "clarification",
+ "clarification_message": "I'm not sure what you'd like me to do.",
+ "available_options": ["Option 1", "Option 2", "Option 3"],
+ "description": "Ask for clarification"
+}
+```
+
+## Key Features
+
+### 1. **Declarative Configuration**

+
+## Running the Demo
+
+```bash
+# Set your API key
+export OPENROUTER_API_KEY="your-api-key-here"
+
+# Run the demo
+python examples/json_demo.py
+```
+
+## Expected Output
+
+```
+=== JSON DAG Demo ===
+
+DAG Configuration:
+{
+ "nodes": {
+ "classifier": {
+ "type": "classifier",
+ "output_labels": ["greet"],
+ "description": "Classify if input is a greeting"
+ },
+ ...
+ }
+}
+
+==================================================
+Executing DAG from JSON config:
+
+Input: 'Hello, I'm Alice!'
+Result: Hello Alice!
+
+Input: 'What's the weather?'
+Clarification: I'm not sure what you'd like me to do. Please try saying hello!
+
+Input: 'Hi there!'
+Result: Hello there!
+```

+
+## Advanced Features
+
+### Streaming Responses
+
+```python
+# Configure for streaming
+config = {
+ "provider": "openai",
+ "model": "gpt-4",
+ "stream": True
+}
+
+client = llm_service.get_client(config)
+
+# Stream response
+for chunk in client.generate_stream("Tell me a story"):
+ print(chunk.content, end="", flush=True)
+```
+
+### Function Calling
+
+```python
+# Define functions
+functions = [
+ {
+ "name": "get_weather",
+ "description": "Get weather information",
+ "parameters": {
+ "type": "object",
+ "properties": {
+ "location": {"type": "string"},
+ "unit": {"type": "string", "enum": ["celsius", "fahrenheit"]}
+ },
+ "required": ["location"]
+ }
+ }
+]
+
+# Configure with functions
+config = {
+ "provider": "openai",
+ "model": "gpt-4",
+ "functions": functions,
+ "function_call": "auto"
+}
+
+client = llm_service.get_client(config)
+response = client.generate("What's the weather in New York?")
+```
+
+### Structured Output

+ "response_format": {
+ "type": "json_object",
+ "schema": {
+ "type": "object",
+ "properties": {
+ "name": {"type": "string"},
+ "age": {"type": "integer"},
+ "email": {"type": "string"}
+ }
+ }
+ }
+}
+
+client = llm_service.get_client(config)
+response = client.generate("Extract user information from: John is 25 years old, email: john@example.com")
+```
+
+## Cost Tracking
+
+### Real-Time Cost Calculation
+
+```python
+from intent_kit.services.ai.pricing_service import PricingService
+
+# Initialize pricing service
+pricing_service = PricingService()
+
+# Track costs
+config = {
+ "provider": "openai",
+ "model": "gpt-4"
+}
+
+client = llm_service.get_client(config)
+response = client.generate("Hello world")
+
+# Get cost information
+print(f"Input tokens: {response.input_tokens}")
+print(f"Output tokens: {response.output_tokens}")
+print(f"Total cost: ${response.cost:.4f}")
+```
+
+### Cost Optimization
+
+```python
+# Compare costs across providers
+providers = [
+ {"provider": "openai", "model": "gpt-4o"},
+ {"provider": "anthropic", "model": "claude-3-7-sonnet-20250219"},
+ {"provider": "google", "model": "gemini-2.5-flash-lite"},
+ {"provider": "openrouter", "model": "mistralai/mistral-7b-instruct"}
+]
+
+for provider_config in providers:
+ client = llm_service.get_client(provider_config)
+ response = client.generate("Hello world")
+ print(f"{provider_config['provider']}: ${response.cost:.4f}")
+```
+
+## Performance Monitoring
+
+### Response Time Tracking
+
+```python
+import time
+
+# Track performance
+start_time = time.time()
+response = client.generate("Complex query")
+end_time = time.time()
+
+print(f"Response time: {end_time - start_time:.2f} seconds")
+print(f"Tokens per second: {response.output_tokens / (end_time - start_time):.2f}")
+```
+
+### Batch Processing
+
+```python
+# Process multiple requests efficiently
+queries = [
+ "What is AI?",
+ "Explain machine learning",
+ "Describe neural networks"
+]
+
+responses = []
+for query in queries:
+ response = client.generate(query)
+ responses.append(response)
+
+# Aggregate metrics
+total_cost = sum(r.cost for r in responses)
+total_tokens = sum(r.input_tokens + r.output_tokens for r in responses)
+print(f"Total cost: ${total_cost:.4f}")
+print(f"Total tokens: {total_tokens}")
+```
+
+## Error Handling
+
+### Provider-Specific Errors
+
+```python
+from intent_kit.services.ai.base_client import LLMError
+
+try:
+ response = client.generate("Hello world")
+except LLMError as e:
+ print(f"LLM Error: {e.message}")
+ print(f"Provider: {e.provider}")
+ print(f"Model: {e.model}")
+except Exception as e:
+ print(f"Unexpected error: {e}")
+```
+
+### Retry Logic
+
+```python
+import time
+from functools import wraps
+
+def retry_on_failure(max_retries=3, delay=1):
+ def decorator(func):
+ @wraps(func)
+ def wrapper(*args, **kwargs):
+ for attempt in range(max_retries):
+ try:
+ return func(*args, **kwargs)
+ except LLMError as e:
+ if attempt == max_retries - 1:
+ raise
+ time.sleep(delay * (2 ** attempt)) # Exponential backoff
+ return None
+ return wrapper
+ return decorator
+
+@retry_on_failure(max_retries=3)
+def generate_with_retry(client, prompt):
+ return client.generate(prompt)
+```
+
+## Best Practices
+
+### 1. Model Selection
+
+```python
+# Choose appropriate model for task
+task_models = {
+ "conversation": "gpt-4o",
+ "code_generation": "claude-3-7-sonnet-20250219",
+ "reasoning": "gemini-2.5-pro",
+ "local_development": "llama2",
+ "cost_optimized": "mistralai/mistral-7b-instruct"
+}
+```
+
+### 2. Cost Management
+
+```python
+# Set budget limits
+def generate_within_budget(client, prompt, max_cost=0.01):
+ response = client.generate(prompt)
+ if response.cost > max_cost:
+ raise ValueError(f"Cost ${response.cost:.4f} exceeds budget ${max_cost:.4f}")
+ return response
+```
+
+### 3. Caching
+
+```python
+import hashlib
+import json
+
+class ResponseCache:
+ def __init__(self):
+ self.cache = {}
+
+ def get_cache_key(self, config, prompt):
+ data = json.dumps({"config": config, "prompt": prompt}, sort_keys=True)
+ return hashlib.md5(data.encode()).hexdigest()
+
+ def get(self, config, prompt):
+ key = self.get_cache_key(config, prompt)
+ return self.cache.get(key)
+
+ def set(self, config, prompt, response):
+ key = self.get_cache_key(config, prompt)
+ self.cache[key] = response
+
+# Use caching
+cache = ResponseCache()
+cached_response = cache.get(config, prompt)
+if cached_response:
+ return cached_response
+
+response = client.generate(prompt)
+cache.set(config, prompt, response)
+return response
+```
+
+### 4. Environment Management
+
+```python
+# Use environment-specific configurations
+import os
+
+def get_llm_config():
+ env = os.getenv("ENVIRONMENT", "development")
+
+ if env == "production":
+ return {
+ "provider": "openai",
+ "model": "gpt-4o",
+ "temperature": 0.1 # More deterministic
+ }
+ elif env == "development":
+ return {
+ "provider": "ollama",
+ "model": "llama2",
+ "temperature": 0.7 # More creative
+ }
+ else:
+ return {
+ "provider": "anthropic",
+ "model": "claude-3-5-haiku-20241022",
+ "temperature": 0.5
+ }
+```
+
+## Integration with DAGs
+
+### Using AI Services in DAGs
+
+```python
+from intent_kit import DAGBuilder
+from intent_kit.services.ai.llm_service import LLMService
+
+# Initialize LLM service
+llm_service = LLMService()
+
+# Create DAG with AI services
+builder = DAGBuilder()
+
+# Set default LLM configuration
+builder.with_default_llm_config({
+ "provider": "openai",
+ "model": "gpt-4o",
+ "temperature": 0.7
+})
+
+# Add nodes that use AI services
+builder.add_node("classifier", "classifier",
+ output_labels=["greet", "weather"],
+ description="Classify user intent")
+
+builder.add_node("extractor", "extractor",
+ param_schema={"location": str, "date": str},
+ description="Extract parameters")
+
+# Build and execute
+dag = builder.build()
+context = DefaultContext()
+context.set("llm_service", llm_service)
+
+result = dag.execute("What's the weather in New York tomorrow?", context)
+```
+
+### Context-Aware AI Configuration
+
+```python
+# Use different models for different tasks
+def get_task_specific_config(task_type):
+ configs = {
+ "classification": {
+ "provider": "anthropic",
+ "model": "claude-3-5-haiku-20241022",
+ "temperature": 0.1
+ },
+ "extraction": {
+ "provider": "openai",
+ "model": "gpt-4o",
+ "temperature": 0.0
+ },
+ "conversation": {
+ "provider": "google",
+ "model": "gemini-2.5-flash-lite",
+ "temperature": 0.7
+ },
+ "cost_optimized": {
+ "provider": "openrouter",
+ "model": "mistralai/mistral-7b-instruct",
+ "temperature": 0.7
+ }
+ }
+ return configs.get(task_type, configs["conversation"])
+```

+# Utilities
+
+Intent Kit provides a comprehensive set of utility modules that support core functionality, including type validation, text processing, performance monitoring, logging, and reporting.
+
+## Overview
+
+The utilities module includes:
+- **Type Coercion** - Advanced type validation and conversion
+- **Text Utils** - Text processing and manipulation
+- **Performance Utils** - Performance monitoring and cost tracking
+- **Logger** - Structured logging system
+- **Report Utils** - Report generation and formatting
+- **Typed Output** - Type-safe output handling
+
+## Type Coercion
+
+The `type_coercion` module provides robust type validation and conversion capabilities.
+
+### Basic Type Validation
+
+```python
+from intent_kit.utils.type_coercion import validate_type, resolve_type
+
+# Validate basic types
+result = validate_type("42", int)
+print(result) # 42
+
+result = validate_type("3.14", float)
+print(result) # 3.14
+
+result = validate_type("true", bool)
+print(result) # True
+
+# Handle invalid types
+try:
+ result = validate_type("not_a_number", int)
+except TypeValidationError as e:
+ print(f"Validation error: {e}")
+```
+
+### Complex Type Validation
+
+```python
+from intent_kit.utils.type_coercion import validate_raw_content
+
+# Validate complex structures
+data = {
+ "name": "John",
+ "age": "25",
+ "scores": ["85", "92", "78"],
+ "active": "true"
+}
+
+schema = {
+ "name": str,
+ "age": int,
+ "scores": list,
+ "active": bool
+}
+
+validated_data = validate_raw_content(data, dict)
+print(validated_data)
+# {
+# "name": "John",
+# "age": 25,
+# "scores": ["85", "92", "78"],
+# "active": True
+# }
+```
+
+### Custom Type Validation
+
+```python
+from typing import Union, List
+from intent_kit.utils.type_coercion import TypeValidationError
+
+# Define custom validation rules
+def validate_email(value: str) -> str:
+ if "@" not in value:
+ raise TypeValidationError(f"Invalid email format: {value}")
+ return value
+
+def validate_age(value: Union[int, str]) -> int:
+ age = validate_type(value, int)
+ if age < 0 or age > 150:
+ raise TypeValidationError(f"Age must be between 0 and 150: {age}")
+ return age
+
+# Use custom validators
+schema = {
+ "email": validate_email,
+ "age": validate_age,
+ "tags": List[str]
+}
+
+data = {
+ "email": "user@example.com",
+ "age": "25",
+ "tags": ["python", "ai", "ml"]
+}
+
+validated = validate_raw_content(data, dict)
+```
+
+## Text Utils
+
+The `text_utils` module provides comprehensive text processing capabilities.
+
+### Text Cleaning and Normalization
+
+```python
+from intent_kit.utils.text_utils import (
+ clean_text, normalize_text, extract_keywords,
+ calculate_similarity, split_text
+)
+
+# Clean and normalize text
+text = " Hello, World! How are you? "
+cleaned = clean_text(text)
+print(cleaned) # "Hello, World! How are you?"
+
+normalized = normalize_text(text)
+print(normalized) # "hello world how are you"
+
+# Extract keywords
+keywords = extract_keywords("Machine learning is a subset of artificial intelligence")
+print(keywords) # ["machine", "learning", "subset", "artificial", "intelligence"]
+```
+
+### Text Similarity
+
+```python
+from intent_kit.utils.text_utils import calculate_similarity
+
+# Calculate similarity between texts
+text1 = "Hello, how are you?"
+text2 = "Hi, how are you doing?"
+text3 = "What's the weather like?"
+
+similarity_1_2 = calculate_similarity(text1, text2)
+similarity_1_3 = calculate_similarity(text1, text3)
+
+print(f"Similarity 1-2: {similarity_1_2:.2f}") # Higher similarity
+print(f"Similarity 1-3: {similarity_1_3:.2f}") # Lower similarity
+```
+
+### Text Splitting and Chunking
+
+```python
+from intent_kit.utils.text_utils import split_text, chunk_text
+

+print(sentiment) # {"positive": 0.9, "negative": 0.1}
+```
+
+## Performance Utils
+
+The `perf_util` module provides comprehensive performance monitoring and cost tracking.
+
+### Basic Performance Tracking
+
+```python
+from intent_kit.utils.perf_util import PerfUtil
+
+# Initialize performance utility
+perf = PerfUtil()
+
+# Track execution time
+with perf.timer("data_processing"):
+ # Your code here
+ import time
+ time.sleep(1)
+
+# Get timing information
+timings = perf.get_timings()
+print(timings) # {"data_processing": 1.002}
+```
+
+### Cost Tracking
+
+```python
+from intent_kit.utils.perf_util import PerfUtil
+
+perf = PerfUtil()
+
+# Track token usage and costs
+perf.record_tokens(
+ provider="openrouter",
+ model="google/gemma-2-9b-it",
+ input_tokens=100,
+ output_tokens=50
+)
+
+# Get cost information
+costs = perf.get_costs()
+print(costs) # {"openrouter": {"google/gemma-2-9b-it": 0.0023}}
+
+# Get total cost
+total_cost = perf.get_total_cost()
+print(f"Total cost: ${total_cost:.4f}")
+```
+
+### Performance Monitoring
+
+```python
+from intent_kit.utils.perf_util import PerfUtil
+
+perf = PerfUtil()
+
+# Monitor multiple operations
+with perf.timer("classification"):
+ # Classification logic
+ pass
+
+with perf.timer("extraction"):
+ # Extraction logic
+ pass
+
+with perf.timer("action_execution"):
+ # Action execution
+ pass
+
+# Get detailed performance report
+report = perf.generate_report()
+print(report)
+# {
+# "timings": {
+# "classification": 0.5,
+# "extraction": 1.2,
+# "action_execution": 0.3
+# },
+# "costs": {...},
+# "summary": {
+# "total_time": 2.0,
+# "total_cost": 0.005
+# }
+# }
+```
+
+### Memory Usage Tracking
+
+```python
+from intent_kit.utils.perf_util import PerfUtil
+import psutil
+
+perf = PerfUtil()
+
+# Track memory usage
+initial_memory = psutil.Process().memory_info().rss / 1024 / 1024 # MB
+perf.record_memory_usage("start", initial_memory)
+
+# After processing
+final_memory = psutil.Process().memory_info().rss / 1024 / 1024
+perf.record_memory_usage("end", final_memory)
+
+memory_usage = perf.get_memory_usage()
+print(f"Memory used: {memory_usage['end'] - memory_usage['start']:.2f} MB")
+```
+
+## Logger
+
+The `logger` module provides structured logging capabilities.
+
+### Basic Logging
+
+```python
+from intent_kit.utils.logger import Logger
+
+# Create logger instance
+logger = Logger("my_component")
+
+# Basic logging
+logger.info("Component initialized")
+logger.warning("Deprecated feature used")
+logger.error("An error occurred", exc_info=True)
+logger.debug("Debug information")
+```
+
+### Structured Logging
+
+```python
+from intent_kit.utils.logger import Logger
+
+logger = Logger("dag_execution")
+
+# Log with structured data
+logger.info("DAG execution started", extra={
+ "dag_id": "booking_flow",
+ "user_id": "user123",
+ "input_length": 50
+})
+
+logger.info("Node executed", extra={
+ "node_id": "classifier",
+ "execution_time": 0.5,
+ "result": "weather"
+})
+```
+
+### Log Configuration
+
+```python
+from intent_kit.utils.logger import Logger, configure_logging
+
+# Configure logging
+configure_logging(
+ level="INFO",
+ format="json",
+ output_file="logs/app.log"
+)
+
+# Create logger with specific configuration
+logger = Logger("custom_logger", level="DEBUG")
+```
+
+### Performance Logging
+
+```python
+from intent_kit.utils.logger import Logger
+
+logger = Logger("performance")
+
+# Log performance metrics
+def log_performance_metrics(operation, duration, tokens=None, cost=None):
+ logger.info("Performance metrics", extra={
+ "operation": operation,
+ "duration_seconds": duration,
+ "tokens_used": tokens,
+ "cost_usd": cost
+ })
+
+# Usage
+log_performance_metrics("llm_generation", 1.5, tokens=150, cost=0.003)
+```
+
+## Report Utils
+
+The `report_utils` module provides comprehensive reporting capabilities.
+
+### Basic Report Generation
+
+```python
+from intent_kit.utils.report_utils import ReportGenerator
+
+# Create report generator
+reporter = ReportGenerator()
+
+# Add data to report
+reporter.add_section("execution_summary", {
+ "total_requests": 100,
+ "successful_requests": 95,
+ "failed_requests": 5,
+ "average_response_time": 1.2
+})
+
+reporter.add_section("cost_analysis", {
+ "total_cost": 0.25,
+ "cost_per_request": 0.0025,
+ "provider_breakdown": {
+ "openai": 0.15,
+ "anthropic": 0.10
+ }
+})
+
+# Generate report
+report = reporter.generate_report()
+print(report)
+```
+
+### Performance Reports
+
+```python
+from intent_kit.utils.report_utils import PerformanceReport
+
+# Create performance report
+perf_report = PerformanceReport()
+
+# Add performance data
+perf_report.add_execution_data({
+ "node_id": "classifier",
+ "execution_time": 0.5,
+ "tokens_used": 100,
+ "cost": 0.002
+})
+
+perf_report.add_execution_data({
+ "node_id": "extractor",
+ "execution_time": 1.2,
+ "tokens_used": 200,
+ "cost": 0.004
+})
+
+# Generate performance summary
+summary = perf_report.generate_summary()
+print(summary)
+# {
+# "total_executions": 2,
+# "total_time": 1.7,
+# "total_cost": 0.006,
+# "average_time": 0.85,
+# "node_breakdown": {...}
+# }
+```
+
+### HTML Report Generation
+
+```python
+from intent_kit.utils.report_utils import HTMLReportGenerator
+
+# Create HTML report
+html_reporter = HTMLReportGenerator()
+
+# Add sections
+html_reporter.add_section("Overview", {
+ "title": "Execution Summary",
+ "content": "This report summarizes the DAG execution performance."
+})
+
+html_reporter.add_metrics("Performance Metrics", {
+ "Response Time": "1.2s",
+ "Cost": "$0.25",
+ "Accuracy": "95%"
+})
+
+# Generate HTML report
+html_content = html_reporter.generate_html()
+with open("report.html", "w") as f:
+ f.write(html_content)
+```
+
+### JSON Report Export
+
+```python
+from intent_kit.utils.report_utils import JSONReportExporter
+
+# Create JSON exporter
+exporter = JSONReportExporter()
+
+# Add report data
+exporter.add_data("execution_results", {
+ "total_requests": 100,
+ "success_rate": 0.95,
+ "average_latency": 1.2
+})
+
+# Export to JSON
+json_data = exporter.export()
+with open("report.json", "w") as f:
+ json.dump(json_data, f, indent=2)
+```
+
+## Typed Output
+
+The `typed_output` module provides type-safe output handling.
+
+### Basic Typed Output
+
+```python
+from intent_kit.utils.typed_output import TypedOutput, OutputType
+
+# Create typed output
+output = TypedOutput(
+ content="Hello, world!",
+ output_type=OutputType.TEXT,
+ metadata={"confidence": 0.95}
+)
+
+# Access typed content
+print(output.content) # "Hello, world!"
+print(output.output_type) # OutputType.TEXT
+print(output.metadata) # {"confidence": 0.95}
+```
+
+### Structured Output
+
+```python
+from intent_kit.utils.typed_output import TypedOutput, OutputType
+
+# Create structured output
+structured_output = TypedOutput(
+ content={
+ "name": "John Doe",
+ "age": 30,
+ "email": "john@example.com"
+ },
+ output_type=OutputType.JSON,
+ metadata={
+ "schema_version": "1.0",
+ "validation_passed": True
+ }
+)
+
+# Validate structured content
+if structured_output.output_type == OutputType.JSON:
+ data = structured_output.content
+ print(f"Name: {data['name']}")
+ print(f"Age: {data['age']}")
+```
+
+### Output Validation
+
+```python
+from intent_kit.utils.typed_output import TypedOutput, OutputType, validate_output
+
+# Create output with validation
+output = TypedOutput(
+ content={"temperature": 25, "humidity": 60},
+ output_type=OutputType.JSON
+)
+
+# Validate output
+is_valid = validate_output(output, {
+ "temperature": (int, lambda x: 0 <= x <= 50),
+ "humidity": (int, lambda x: 0 <= x <= 100)
+})
+
+print(f"Output is valid: {is_valid}")
+```
+
+### Output Transformation
+
+```python
+from intent_kit.utils.typed_output import TypedOutput, OutputType
+
+# Create output
+output = TypedOutput(
+ content="The temperature is 25°C",
+ output_type=OutputType.TEXT
+)
+
+# Transform output
+def extract_temperature(text):
+ import re
+ match = re.search(r'(\d+)°C', text)
+ return int(match.group(1)) if match else None
+
+transformed = output.transform(
+ extract_temperature,
+ OutputType.NUMBER,
+ metadata={"extraction_method": "regex"}
+)
+
+print(transformed.content) # 25
+print(transformed.output_type) # OutputType.NUMBER
+```
+
+## Best Practices
+
+### 1. Type Safety
+
+```python
+# Always use type validation for external data
+from intent_kit.utils.type_coercion import validate_raw_content
+
+def process_user_input(data):
+ schema = {
+ "name": str,
+ "age": int,
+ "email": str
+ }
+
+ try:
+ validated_data = validate_raw_content(data, dict)
+ return validated_data
+ except TypeValidationError as e:
+ logger.error(f"Validation failed: {e}")
+ raise
+```
+
+### 2. Performance Monitoring
+
+```python
+# Use performance utilities consistently
+from intent_kit.utils.perf_util import PerfUtil
+
+perf = PerfUtil()
+
+def expensive_operation():
+ with perf.timer("expensive_operation"):
+ # Your code here
+ result = complex_calculation()
+
+ # Record costs if applicable
+ perf.record_tokens("openrouter", "google/gemma-2-9b-it", 100, 50)
+
+ return result
+```
+
+### 3. Structured Logging
+
+```python
+# Use structured logging for better observability
+from intent_kit.utils.logger import Logger
+
+logger = Logger("dag_execution")
+
+def execute_dag(dag_id, user_input):
+ logger.info("DAG execution started", extra={
+ "dag_id": dag_id,
+ "input_length": len(user_input),
+ "timestamp": datetime.now().isoformat()
+ })
+
+ try:
+ result = dag.execute(user_input)
+ logger.info("DAG execution completed", extra={
+ "dag_id": dag_id,
+ "success": True,
+ "execution_time": result.execution_time
+ })
+ return result
+ except Exception as e:
+ logger.error("DAG execution failed", extra={
+ "dag_id": dag_id,
+ "error": str(e),
+ "success": False
+ }, exc_info=True)
+ raise
+```
+
+### 4. Error Handling
+
+```python
+# Use utilities for robust error handling
+from intent_kit.utils.type_coercion import TypeValidationError
+from intent_kit.utils.logger import Logger
+
+logger = Logger("data_processing")
+
+def safe_data_processing(data):
+ try:
+ # Process data with type validation
+ validated_data = validate_raw_content(data, dict)
+ return process_validated_data(validated_data)
+ except TypeValidationError as e:
+ logger.warning("Data validation failed", extra={
+ "error": str(e),
+ "data_type": type(data).__name__
+ })
+ return None
+ except Exception as e:
+ logger.error("Unexpected error in data processing", exc_info=True)
+ raise
+```
