newt-core

Newt-Agent core types, errors, and the NeMoCode-style tier router.

The router is the NeMoCode inheritance: it classifies an incoming turn into a Tier (FAST / STANDARD / COMPLEX / REVIEW) and asks the configured backends which can serve that tier. The crate also carries the shared configuration model (~/.newt/config.toml), session and memory types, MCP server resolution, metrics, and capability caveat extensions used across the workspace.

It also hosts the shared agentic tool executor used by the TUI and headless paths. Built-in file tools include read_file, write_file, edit_file, delete_file, list_dir, and find, all mediated by the same caveat and prompted-permission checks.
