Rust Skills is a Claude Code plugin that enhances AI-assisted Rust development by using a three-layer cognitive model to provide domain-correct architectural solutions rather than surface-level fixes. It auto-generates skills from Cargo.toml dependencies and includes domain extensions for FinTech, ML, Cloud-Native, and other specialized areas. The plugin supports both full Claude Code integration with hooks and agents, as well as a skills-only mode compatible with any coding agent.
