ovo

Why we included this project

Ovo is a Rust library for teams that want the agent loop embedded in their own binary rather than wiring together Python orchestration. It runs a ReAct-style turn loop with stop gates and compaction, validates structured output, and lets the session host spawn nested child agents at runtime for dynamic delegation. A second mode executes journaled workflows through the Rhai scripting language, so deterministic multi-step behavior can sit alongside free-form model turns. Process isolation is explicit rather than assumed: sandboxing uses macOS Seatbelt or Linux Landlock backends, and the default approval policy denies destructive actions until you wire in your own UI gate. The API stays low-level and the docs are upfront that nothing is turnkey, which suits teams that want fine-grained control over tool execution and budgets.
