## When NOT to use langkit

- Last GitHub push was 596 days ago (dormant maintenance, Nov 22, 2024). Validate activity before betting a new project on langkit.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
