| Recipe | A named shell command with optional declared parameters. |
| Central file | ~/.ndo/central.toml (or $NDO_HOME/central.toml) — recipes available everywhere. |
| Local file | .ndo.toml, found by searching upward from the current directory (git-style). Project-specific recipes. |
| Vars | Named lookup tables ([vars.<group>]) that expand a positional argument into a longer value, keyed by param name. |
| Dependencies | depends = [...] on a recipe — other recipes that run first, in order, deduped across the whole chain. See Dependencies. |
| Settings | ~/.ndo/config.toml — app behavior (shell, editor, color), never recipes. |
