nanocodex

Nanocodex is a Rust crate that serves as the batteries-included façade for the Nanocodex frontier-agent building blocks. It contains no second runtime implementation; instead, it re-exports the owned agent lifecycle and gives lower-level crates stable, named module paths. Depending on nanocodex-agent directly creates the same agent. The crate provides a quick start for building one owned agent, keeping its cheap cloneable handle, and awaiting typed turn results. It supports OpenAI and, when the claude feature is enabled, Anthropic Messages with the same owned agent lifecycle and durability extension. Default features remain durability, mcp, openai, and tools. The root exports only golden-path types, while named modules offer more control for embedding needs. Harness composes explicitly registered construction recipes. When the provider reports aggregate usage for a completed turn, Nanocodex automatically applies the selected model’s published standard or priority rates.
