Scaffolds new Rust projects with best practices for Cargo.toml, linting (clippy, rustfmt), CI pipelines, and workspace organization.
Guides modern Rust development with Cargo, rustc, Clippy, Rustfmt; covers ownership, borrowing, lifetimes, async Tokio, concurrency, error handling, testing, and optimization.

Use the template in assets/workspace-template/:

├── project/ # Library crate (thiserror)
│ ├── Cargo.toml
│ └── src/lib.rs
└── project-cli/ # Binary crate (anyhow + clap)

└── src/main.rs
Split modules when file exceeds ~500 lines or tests take 50%+ of file. See module-organization.md for patterns.
The most critical standard. See error-handling.md for full rules and examples.
Quick check: If you see if let Err or match ... Err without return Err or ?, it's a bug.
