In the Agentic Engineering Sessions aired on June 19th, 2025, Mitchell Hashimoto discusses with Richard Feldman his strategic approach to integrating artificial intelligence in software development, specifically in the context of building Ghostty. Hashimoto emphasizes maintaining architectural control by guiding AI with structured goals to prevent unsustainable solutions, akin to coaching junior engineers with well-defined problems and guardrails. He highlights the parallel workflow with AI, delegating simple tasks like code cleanup while performing quality assurance testing, and acknowledges the AI's proficiency in refactoring code but notes its limitations in handling complex changes in certain programming languages like Zig. Hashimoto also describes using multiple models for comparison, noting success with Claude and expressing dissatisfaction with the verbosity of responses from Gemini. Overall, he underscores AI's current inefficiencies in architectural problem-solving and high-performance data structure work, while leveraging it as a tool for achieving maintainable and senior-quality code.
