Agentic Coding Assistants: Impressive Progress, Persistent Challenges

2025-03-26

Generative AI, particularly LLMs, is revolutionizing software development. This memo details the author's experience using AI coding assistants over several months, revealing significant efficiency gains alongside persistent challenges. The AI frequently misdiagnoses problems, uses brute-force fixes, lacks code reusability, and generates redundant code, impacting team workflow and long-term maintainability. The author categorizes these issues into three impact radiuses: time to commit, team flow, and long-term maintainability, and offers mitigation strategies such as careful code review, regular reflection, and establishing code quality monitoring mechanisms. The core message is that despite rapid AI advancements, developer experience and skills remain crucial.

Conway's Law: Software Architecture Mirrors Organizational Structure

2025-02-05

A prevailing consensus among software architects is the significance of Conway's Law: any organization that designs a system will produce a design whose structure is a copy of the organization's communication structure. This means software architecture often reflects the development team's organization. Ignoring this leads to conflicts between system architecture and organizational structure, increasing development complexity. The article explores three strategies for addressing Conway's Law: ignoring, accepting, and the Inverse Conway Maneuver (adjusting the organizational structure to guide software architecture). The author emphasizes that system architecture and organizational structure evolution should be synchronized throughout software development, and suggests using methods like Domain-Driven Design to aid organizational design.

Automating API Changes with Codemods: A Refactoring Revolution

2025-01-11

This article explores how codemods automate large-scale code changes, especially when dealing with breaking API changes. Leveraging Abstract Syntax Trees (ASTs), codemods precisely automate code transformations, significantly reducing the burden of manual refactoring. The article uses examples like removing stale feature toggles and refactoring complex React components, detailing the process using jscodeshift, and discusses potential pitfalls and solutions when scaling codemods. It highlights codemods' role in improving code quality and maintainability, showcasing a real-world case study of refactoring an Avatar component.

Design Tokens: The Key to Scalable and Consistent UI Architectures

2024-12-18

This article explores the role of design tokens in modern UI architecture. By representing design decisions as data, design tokens serve as a single source of truth, enabling automated code generation across platforms for faster updates and improved design consistency. It details the layered organization of design tokens (option, decision, and component tokens), automated distribution processes, and how to choose the appropriate number of layers and token scope. Finally, it discusses when design tokens are appropriate and their limitations, helping readers determine their suitability for their projects.
