Tool Calling Failure Taxonomy: Stop Blaming Every Failure on the Model

Tool-call failures can originate in selection, arguments, authorization, dependencies, state, or user confirmation. This article provides an actionable taxonomy and metric design to turn vague Agent errors into fixable engineering problems.

Hands-On: Build a Multi-Step Research Agent with LangGraph

Deep research—one question, multiple search rounds, and a synthesized report—is one of the most valuable agent use cases and cannot be solved by single-pass RAG. This article builds a LangGraph research agent that decomposes questions, searches in parallel, reads full text, fills gaps, and writes a report while explaining state graphs, tool calls, and loop

Rate Limiting and Quota Design for AI Applications

Rate limiting for AI apps is more complex than for web apps: there are two cost dimensions (requests and tokens), plus abuse, automated traffic, and single-user spikes. This article covers three layers of limits (user, IP, and global), token quota accounting, graceful degradation, and a quota architecture resilient to malicious usage.

Prompt Versioning and CI

Prompts contain core AI application logic, yet teams often edit them as arbitrary "configuration strings," causing production failures, missing rollback history, and unusable A/B tests. This article explains how to manage prompts like code through versioning, CI evaluations, gradual rollout, and rollback.

Multi-Model Fallback and Resilience Strategies

Binding an entire product to one model API is risky: outages, rate limits, policy changes, price hikes, or account suspension can take it offline instantly. Learn how to build multi-model resilience with primary/backup fallback, intelligent routing, fallback chains, trigger rules, unified interfaces, retries, and circuit breakers.
