Developer warns against over-engineering AI agents for simple tasks

A developer who built over 30 AI workflows for founders and small teams reports a recurring failure mode: teams architect complex agent systems with multiple MCP servers, vector databases, and fallback models, but the actual use case is often just summarizing emails and drafting replies. The post argues that over-engineering for a hypothetical future agent leads to failure, not the model itself.
