Stop runtime exceptions from crashing LLM pipelines. Build type-safe error hierarchies with Scala Either, ADTs, and smart constructors. Real refactor from llm4s turned generic exceptions into 12+ structured error types and debugging.
Stop making contributors guess their way through setup. Build Giter8 templates with working code, CI setup, and zero TODO comments. Real template from llm4s cut onboarding from 20 minutes to 60 seconds, a 95% time saving overall net.
How we turned Issue #94 into a smoother onboarding flow for llm4s. Covers the DX problem, giter8 template design, repo structure, and the decisions that reduce setup friction. Includes lessons on developer empathy and Scala SDK adoption.
