rust — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited rust (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

When solving Rust problems, do not immediately write code. Trace through the cognitive layers first to understand the data's lifecycle, ownership, and constraints.
What is the system trying to achieve?
axum, tokio, Arc<Mutex<T>>).clap, anyhow, strict error formatting).no_std, specific hardware limitations).Ask the core question: Who should own this data?
Box<T>.Rc<T> (use RefCell<T> for mutation).Arc<T> (use Mutex<T> or RwLock<T> for mutation).Why does it need to mutate? Avoid slapping mut everywhere. Prefer returning new values or using tight, scoped mutability.
Use the compiler's strictness as a tool, not an obstacle.
Drop, Clone, Default, Display, From, TryFrom.unwrap() or expect() in production logic. Propagate errors natively via ? and Result.Consult references/ecosystem.md for canonical community crates.
Consult references/borrow-checker.md for diagnostics and resolution paths for common compiler errors (E0382, E0596, E0499).
clone() is an acceptable escape hatch during prototyping, but do not scatter it throughout the code. Revisit the lifetime boundaries as soon as it works.struct UserId(u64); avoids mixing it up with struct OrderId(u64);.match over if let when handling Enums or State Machines. The compiler will notify you when a new variant is added, preventing silent bugs.cargo runcargo clippy -- -D warningscargo fmtcargo testAgent Directive: When writing or editing Rust code, always invoke cargo clippy and cargo test dynamically to validate your implementations before concluding your task.
unsafe BlocksAvoid unsafe blocks. If you must use unsafe for FFI or performance, you MUST thoroughly document the exact safety invariants being upheld inside the block.
Require user confirmation before executing any command with external side effects, including cargo publish and registry operations.
