Prompt Caching in Production: Architecture Patterns for AI Systems
An engineering deep dive on the four caching layers for LLM inference — KV/prefix caching, prompt caching, semantic caching, and exact-response caching — with architecture patterns, provider pricing analysis, and production deployment strategies.

TypeScript is in Maintenance Mode: What the Go Rewrite Means for Production Systems
TypeScript 6.0 is the last JavaScript-based release. The compiler is being rewritten in Go, the JS codebase is in maintenance mode, and most open PRs will be auto-closed. What this means for production systems, tool authors, and the TypeScript contribution model.
State Corruption in Multi-Turn Agent Systems: A Forensic Debugging Guide
A systematic forensic approach to debugging state corruption in multi-turn agent systems — taxonomy, detection patterns, causal tracing, and production instrumentation based on 847 incidents and 13,602 open-source repository issues.
Function-Calling Benchmarks in 2026: What They Actually Measure
A comparative analysis of BFCL v3/v4, tau-bench, MCP-Atlas, FinTrace, and what their differing results reveal about production function-calling reliability.
The Architecture of Tool-Use in Agent Systems
Deep dive on how tool-use actually works in production agent systems: schema design, execution patterns, MCP protocol architecture, deferred loading, programmatic orchestration, and empirical findings from 856 MCP tools.
