An embeddable agent runtime for Rust: any task, any provider, in your own process. Run commands, edit files and search a repository under a layered permission boundary on files, commands and network; gate the result on the project's own test command in any language, or on nothing at all; and keep a full SQLite trace of every step, refusal and budget draw. With an execution sandbox, contained sub-agents, an MCP client, and durable resume for unattended runs.
