## Project history and usage

HawkEye is a Rust command-line tool and GitHub Action for checking, formatting, and removing license headers in source trees. Its package history is centered on supply-chain hygiene: it packages a repetitive repository-maintenance task as a local CLI, container image, prebuilt binary, Cargo install, and CI action.

### Project history

The public GitHub repository was created in January 2023 under the korandoru organization. The README describes the project as a simple license header checker and formatter, with a project-level licenserc.toml configuration file and commands for check, format, and remove workflows.

The project presents itself less as a general license scanner and more as a formatter for copyright/license header policy. Its native-image and prebuilt-binary distribution options fit teams that want fast CI checks without provisioning a full language toolchain.

### Adoption history

The README documents several distribution paths: a GitHub Action, a Docker image, Cargo installation, Arch Linux packaging, and prebuilt release installers. Homebrew, Nix, and pacman packaging in the input facts show adoption by Unix-oriented package ecosystems beyond the upstream release channel.

### How it is used

Typical use is to add a licenserc.toml file at a repository root, run hawkeye check in CI, and use hawkeye format when files need an automatic header fix. The same executable can also remove headers, which makes it useful for migrations between license-header policies.

### Why package nerds care

HawkEye matters to package-maintenance workflows because license headers are a common release-review nuisance: too small to deserve a bespoke framework, but common enough to fail CI and release audits. A single static-feeling CLI with GitHub Action support is the useful boring shape for that job.

### Timeline

- 2023: Public GitHub repository created.
- 2023: README-documented licenserc.toml workflow uses 2023 as the example inception year.
- 2020s: Distribution expands across Cargo, prebuilt binaries, Docker, GitHub Actions, and downstream package managers.

### Related projects

- Related tools include license scanners and formatters used in CI, but HawkEye's closest practical peers are repository policy tools that enforce source-header conventions rather than dependency-license inventories.
