Rust Development

Commands

• cargo build - Build (debug only)
• cargo test - Run tests
• cargo fmt - Format code (run after changes)
• cargo clippy - Lint (run after changes)

Dependencies

• MUST use cargo add <crate> to add dependencies - never manually edit Cargo.toml for dependencies
• ALWAYS ask the user for approval before adding any new dependency
• Only suggest well-known, widely-used crates with good maintenance records
• Prefer crates from the Rust ecosystem's trusted maintainers (e.g., tokio-rs, serde-rs, rust-lang)
• Check crate download counts and recent activity as indicators of reliability
• ALWAYS run cargo audit after adding a new dependency
• ALWAYS report any vulnerabilities or issues from cargo audit to the user - never silently ignore audit results
