Would You Choose a Library Because AI Writes It Better?

In a recent exploration of modern development, developer Erikch examines whether coding agents should influence the choice of software libraries. As AI tools like Claude Code and Kiro become more proficient at writing complex TypeScript, libraries such as Effect and StyleX are gaining attention for their ability to provide structured, type-safe environments that agents can navigate effectively. While these tools offer significant advantages in error handling and visual state management, they often introduce steeper learning curves and more complex abstractions. The author argues that while agent-friendly libraries may become the new standard, developers must balance this efficiency with the need for human maintainability. Ultimately, the decision to adopt a library should not rely solely on how well an AI can write it, but also on the team's ability to review, debug, and own the long-term architecture of the application.
