Create tools using the @tool decorator with proper type annotations and clear descriptions. Handle errors gracefully and return meaningful results.
Implement stateful tools that maintain connections, track history, and manage resources throughout their lifecycle.
Use ToolNode and tools_condition for basic tool integration, allowing agents to decide when to use tools and handle the results appropriately.
Implement sophisticated tool planning, dependency management, and multi-step execution with conditional routing based on tool execution results.
Create tools that make HTTP requests to external APIs with proper error handling, timeout management, and response formatting.
Implement web scraping capabilities with user agent headers, content extraction using CSS selectors, and content length management.
Build tools for data analysis that can load various data formats, perform statistical operations, and generate meaningful insights from datasets.
Create secure file system tools with path validation, operation restrictions, and comprehensive error handling for file management tasks.
Implement resilient tool execution with retry logic, exponential backoff, and jitter to handle temporary failures gracefully.
Use circuit breaker patterns to prevent cascading failures when external services become unavailable. Monitor failure rates and temporarily disable failing tools to protect the overall system.
Remember: Great tools make great agents. Focus on building reliable, efficient, and well-documented tools that solve real problems effectively!
