Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“Typed errors and dependency injection for TypeScript done right. The platform modules (HTTP, Schema, SQL) are production-grade.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Steep learning curve and the functional programming style isn't for everyone. The benefits are real but the adoption cost is high.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“Effect brings Scala/Haskell-level reliability to TypeScript. As TypeScript applications grow in complexity, Effect becomes more valuable.”
