A minimal, extensible terminal coding agent you can reshape
Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.

Free collaborative workspaces for live coding interviews
Several participants can edit multiple files in the same workspace simultaneously, with a shared terminal running alongside the editor.
Each workspace runs in its own Firecracker microVM with no network access, hard CPU and memory caps and automatic teardown when idle.
Multi-party video is embedded in the workspace, and every session can be recorded and replayed later, capturing code edits, terminal output, test results and scores.
Attach structured interview problems with visible and hidden test cases plus a custom rubric covering correctness, complexity, communication and code quality.
