Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“The approval flow is brilliant — you see every action before it executes. More transparent than Cursor's agent mode. Great for complex multi-file refactors.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Uses more API tokens than alternatives because of the autonomous approach. Budget accordingly. But the quality of multi-step reasoning is impressive.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“Cline represents the VS Code extension approach to AI coding — extend your existing IDE rather than replacing it. That strategy has legs for developers who don't want to switch editors.”
