A minimal terminal coding-agent harness with a small four-tool core (read, write, edit, bash) and a typed TypeScript extension system for skills, tools, prompt templates, and themes; supports 15+ LLM providers.
Strengths
- Tiny, opinionated core that stays out of your workflow
- Extensible via typed TypeScript skills and shareable packages
Tradeoffs
- Skips built-in sub-agents and plan mode by design
- Younger extension ecosystem
