Episode notes
From Solo Tool To Community Hit
- Carmine built Ruby LLM for his own company needs and shared it publicly four days later after initial use.
- Rapid community adoption surprised him and turned a personal tool into a widely used gem.
Design For Simplicity And Swapability
- Carmine emphasizes simple defaults and escape hatches: make simple tasks trivial and keep complex options possible.
- He treats models/providers as commodities and focuses on stable, small-surface APIs instead of provider lock-in.
Adopt Progressive Disclosure
- Use progressive disclosure: start with a minimal call and layer on model, provider, or parameters only as needed.
- This keeps code readable and avoids large, brittle configuration blocks.
