Strengths	+ Fully open source + Multi-model (Anthropic, OpenAI, OpenRouter, local) + Git-native commit-per-change workflow	+ Mature primitives (skills, hooks, plugins, MCP, subagents) + Official Anthropic-supported harness + Strong ecosystem of community plugins/marketplaces
Tradeoffs	− Less polished than IDE-based harnesses − No managed plugin ecosystem	− Terminal-first UX may not fit non-engineer users
