## Project history and usage

SkyWalking Eyes, packaged by Homebrew as license-eye, is an Apache SkyWalking support tool for checking and fixing license headers and resolving dependency licenses.

### Project history

SkyWalking Eyes grew inside the Apache SkyWalking ecosystem as a Go-based compliance helper for Apache-style release hygiene. The README describes the tool as usable in GitHub Actions or on a local machine, with .licenserc.yaml controlling header and dependency checks.

The 0.4.0 release on July 11, 2022 reorganized GitHub Actions into separate header and dependency actions, added Rust Cargo dependency support, supported license expressions in dependency checks, and added multiple-license support in header configuration. The Apache downloads page lists SkyWalking Eyes among support tools for development and testing.

### Adoption history

The project is most naturally adopted by Apache and Apache-adjacent repositories that need automated license headers, dependency license resolution, pull-request comments, and repeatable CI checks. The README documents GitHub Actions usage, Docker usage, and local CLI commands such as license-eye header check and license-eye dep resolve.

### How it is used

Users add .licenserc.yaml at the repository root, configure header ownership and dependency files such as pom.xml, Cargo.toml, package.json, go.mod, and Gemfile.lock, then run the CLI or GitHub Actions in check, fix, diff, resolve, or dependency-check modes.

### Why package nerds care

license-eye is package-nerdy because it turns licensing metadata into CI-enforced source hygiene. It sits at the intersection of SPDX identifiers, generated dependency graphs, Apache release rules, lockfiles, and automated header repair.

### Timeline

- 2022-07-11: SkyWalking Eyes 0.4.0 reorganized GitHub Actions and expanded dependency-license checking.
- 2025-10-27: Apache listed SkyWalking Eyes 0.8.0 source and distribution artifacts on the SkyWalking downloads page.
- 2025: The README documented separate header and dependency GitHub Actions plus local CLI and Docker workflows.

### Related projects
