- type
- Coding agent
- interface
- Terminal (CLI/TUI) + Desktop (macOS/Windows, React app)
- openSource
- Yes (MIT)
- lineage
- Recursive L0-L4 multi-agent role split (coordinator, planner, implementer, reviewer, verifier); SQLite-backed persistent memory; Git worktree isolation per task; model-agnostic (OpenAI, Anthropic, DeepSeek, Gemini, Groq, Ollama, vLLM, or OrcaRouter)
- note
- Show HN 2026-08-29 ('An agent harness pushing DeepSeek to Opus-tier coding (82%)'). Vendor claims +14.6%/+13 tasks over OpenCode on Terminal-Bench 2.1 using identical models and budgets, i.e. the harness architecture itself (not model choice) drives the gain; that benchmark comparison is vendor-self-reported, not independently verified.
