Coding Agents Do Not Replace Technical Proficiency — They Demand More of It

This article argues that coding agents (like Cursor, Claude Code, GitHub Copilot) do not replace technical proficiency but demand more of it. The author, an experienced developer, explains that while these tools accelerate coding, they rely on the user's deep understanding of codebase structure, conventions, and past decisions to produce correct, maintainable code. Without this knowledge, developers risk accepting subtly flawed outputs that compound over time. The piece covers how LLMs augment rather than replace developers, the importance of steering agents with context, the experience gap in agent interactions, and why speed must be balanced with correctness. It emphasizes that technical proficiency is a prerequisite for leveraging these tools effectively, not something they eliminate.
