VS Code extension that turns the editor into an agentic coder with real file-system access, terminal control, and multi-step task execution. It ships role-specific modes — Architect, Code, Ask, Debug, Test — each with its own prompt and tool permissions, and can hand off between them mid-task. Model-agnostic: connect any provider key, from frontier APIs to a local model, and pay only for your own token usage.
