## Projektgeschichte und Nutzung

usage is both a specification and a CLI for describing command-line interfaces. The official README compares a Usage spec to OpenAPI for CLIs, covering arguments, flags, environment variables, and config files so downstream tools can generate completions, documentation, man pages, parsers, SDKs, and framework scaffolding.

### Projektgeschichte

The project grew out of the modern CLI tooling ecosystem around jdx's tools and the KDL document language. Public GitHub releases show early v0.1.x releases in 2024 and v3.x releases in 2026, while the docs describe an expanding scope from shell completions and man pages toward type-safe SDK generation.

### Adoptionsgeschichte

The official CLI docs list installation through mise, Cargo, Homebrew, and Arch Linux. The input metadata also records Homebrew, Nix, and pacman package names, indicating adoption by users who want the same CLI-spec tool available across developer workstations and Linux distributions.

### Wie es verwendet wird

A Usage spec is written in KDL and can describe a CLI's name, binary, about text, version, author, license, flags, arguments, subcommands, config files, environment variables, and defaults. The `usage` CLI then consumes that spec to generate shell completions, Markdown, man pages, JSON, and related artifacts.

### Warum Paket-Nerds sich dafür interessieren

Package nerds care about usage because it treats CLI metadata as a portable build artifact. Instead of each package separately hand-maintaining completions, man pages, and docs, maintainers can ship a spec and generate those outputs consistently.

### Zeitleiste

- 2024: Early v0.1.x GitHub releases published.
- 2026-06-23: GitHub release v3.5.3 published.

### Related projects

- The official docs relate Usage to OpenAPI for CLIs, KDL as the spec language, and integrations for CLI frameworks such as clap, Cobra, Click, Typer, yargs, oclif, and Commander.js.
