The first 80% of the project went smoothly with Claude writing tests and making rapid progress, but the final 20% became a frustrating slog as Claude struggled with consistency across sessions, made unauthorized design decisions, and couldn't debug its own complex implementations. Key lessons include: LLMs excel at well-constrained transliteration tasks with good test coverage, but struggle with maintaining coherent vision across multi-session projects and debugging poorly-designed code they created. The project succeeded in creating a functional pure-Go RISC-V emulator with VirtIO devices and networking, but revealed significant limitations in using LLMs for complex software development. ## Full article daily.dev links to this article rather than hosting it.
