Reviewer scorecard
“This is my daily driver. The codebase awareness is unreal — it understands project structure, conventions, and dependencies without being told. Multi-file refactors just work.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Rate limits are the only downside. When it's running smoothly, it's the best coding assistant available. When you hit limits, you're stuck waiting. Plan for that.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“The terminal-first approach was the right call. Developers live in their terminal. This isn't an IDE plugin — it's an AI-native development environment.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
