AI Architecture Analysis
This repository is indexed by RepoMind. By analyzing cue-lang/cue in our AI interface, you can instantly generate complete architecture diagrams, visualize control flows, and perform automated security audits across the entire codebase.
Our Agentic Context Augmented Generation (Agentic CAG) engine loads full source files into context on-demand, avoiding the fragmentation of traditional RAG systems. Ask questions about the architecture, dependencies, or specific features to see it in action.
Repository Overview (README excerpt)
Crawler view[ ]() CUE - _Configure, Unify, Execute_ CUE makes it easy to validate data, write schemas, and ensure configurations align with policies. CUE works with a wide range of tools and formats that you're already using such as Go, JSON, YAML, TOML, XML, OpenAPI, Protobuf, and JSON Schema. For more information and documentation, including __tutorials and guides__, see cuelang.org. Download and Install The full range of installation methods for the command are listed on cuelang.org, including the official container image suitable for use with Docker. Release builds Download the latest release from GitHub. Install from Source You need Go 1.25 or later to install CUE from source: go install cuelang.org/go/cmd/cue@latest You can also the repository and build it directly via . Built binaries include version information as reported by , which derives from the VCS. We recommend that downstream packagers build releases from git tags rather than source archives to ensure this works. Learning CUE The fastest way to learn the basics is to follow the language tour on the website. The cuelang.org website also contains more documentation, including tutorials, how-to guides, concept guides, and references.

For example, if CUE v0.7.0 is released when Go's latest version is 1.21.5, v0.7.x including any following bugfix releases will require Go 1.20 or later.
