Let Claude Diagnose Its Own Tool Errors — Building a Self-Correction Loop with the Anthropic API
Learn how to handle Tool Use failures gracefully by feeding error details back to Claude using the is_error flag, enabling self-diagnosis and automatic retry. Includes working Python code and production antipatterns to avoid.
Building a 'Think-and-Search' AI Agent — Claude API Extended Thinking × Tool Use
A deep dive into combining Claude API Extended Thinking and Tool Use. Covers frequent errors, a complete research agent implementation in Python, plus cost estimation, timeout design, and error recovery for production use.
How to Fix the "Tool Result Could Not Be Submitted" Error in Claude
A practical guide to diagnosing and fixing the "tool result could not be submitted" error in Claude's tool use API, based on real development experience.
Shipping Generative UI on Claude API: A Production Pattern for Streaming Dynamic Components with Tool Use and JSON Schema
Combine Claude's Tool Use, JSON Schema, and partial JSON streaming to render AI-assembled UI components safely. We cover registry design, type-safety, fallback, and the pitfalls you only learn after running this in production.
Using tool_choice to Cut Wasted Inference: Four Modes and Cost Patterns for Production
tool_choice is one of the most underused parameters in the Claude API. The four modes — auto, any, tool, and none — each change both behavior and token cost. Here are the patterns I reach for in production, with runnable code.
Running Claude API Parallel Tool Use in Production — Controlling Concurrency, Designing for Partial Failure, and Cutting Latency
Claude API's parallel tool use can cut agent latency in half — but partial failures and state conflicts show up fast in production. Here's how to control concurrency, design error handling, and add observability.
Inserting Approval Gates Into Your Agents — A Production Design for Human-in-the-Loop With the Claude API
Once you put an agent in production, the requirement 'please get a human to approve just this specific decision' appears within days. This guide walks through the design patterns for retrofitting approval gates and handling suspend/resume correctly, with working code.
Claude API with Go: Production— Anthropic Go SDK, Concurrency, Tool Use & Microservice Integration
A practical guide to using Claude API with Go in production. Covers streaming with goroutines, concurrent Tool Use, rate limiting with channels, Gin/Echo integration, graceful shutdown, and Kubernetes deployment with working code examples.
Claude API Think Tool — Dramatically Improve Tool Call Accuracy with Interleaved Reasoning in Agentic Workflows
Master the Claude API Think Tool pattern. Learn the key differences from Extended Thinking, implement interleaved reasoning in agent loops, and apply production design patterns that improve tool call accuracy by up to 54%.
Building Automated Agentic Loops with Claude SDK Tool Runner
Learn how to use Claude SDK's Tool Runner and Tool Helpers to build automated tool-calling loops (agentic loops) with practical code examples in Python and TypeScript.
Claude API Real-time Multimodal Agent Architecture: Design Patterns & Implementation
