LLM agent workflow OS with a Markdown DSL. Constrained, validated, replayable execution. Predictability over autonomy.

Lightweight terminal AI agent in Rust, built for long-running work. The model's only tool is the shell; via the shellboy CLI it searches and forks its own history and delegates to child agents. Requests are saved before execution; failures wait for explicit recovery. Single binary, local SQLite, OpenAI Responses API–compatible. Windows/macOS/Linux.

Browser UI for Shellboy, the long-running terminal AI agent. Runs beside your Shellboy so you can read and drive conversations from a desktop or phone: live progress, collapsible tool output, a tiled monitor of many Threads, an inbox of questions waiting on you, and local Apps. Local IPC only, single binary, MIT.
