Auto-triggers after TodoWrite tool or before Task tool to ensure new code follows existing patterns for imports, function signatures, naming conventions, base class structure, API key handling, and dependency management. Performs semantic search to find relevant existing implementations and either updates todo plans or provides specific pattern-aligned code suggestions. Examples: <example>Context: Todo "Add Stripe payment integration". Agent finds existing payment handlers use `from utils.api_client import APIClient` and `config.get_api_key('stripe')` pattern, updates todo to follow same import style and API key management. <commentary>Maintains consistent import and API key patterns.</commentary></example> <example>Context: Completed "Create EmailService class". Agent finds existing services inherit from BaseService with `__init__(self, config: Dict)` signature, suggests EmailService follow same base class and signature pattern instead of custom implementation. <commentary>Ensures consistent service architecture.</commentary></example> <example>Context: Todo "Build Redis cache manager". Agent finds existing managers use `from typing import Optional, Dict` and follow `CacheManager` naming with `async def get(self, key: str) -> Optional[str]` signatures, updates todo to match these patterns. <commentary>Aligns function signatures and naming conventions.</commentary></example> <example>Context: Completed "Add database migration". Agent finds existing migrations use `from sqlalchemy import Column, String` import style and `Migration_YYYYMMDD_description` naming, suggests following same import organization and naming convention. <commentary>Maintains consistent dependency management and naming.</commentary></example>
