The 60-Line AI Agent: Breaking Free From Framework Bloat

Rather than relying on heavyweight frameworks like LangChain or CrewAI, this guide demonstrates how the Anthropic SDK enables building functional AI agents in just 60 lines of Python. By revealing the core Observe-Think-Act mechanics and eliminating unnecessary abstraction, developers gain clarity on what agents actually need versus framework convenience. This minimal-viable approach could shift team decisions away from framework-heavy tools toward more direct implementations.
