**ALWAYS USE** when working with Rust code. This skill contains 45 rules that prevent common bugs. Trigger on ANY of these: - Editing .rs files or Cargo.toml - Writing new Rust functions, structs, enums, or impl blocks - Reviewing Rust code before committing - Debugging Rust errors (borrow checker, Option/Result, lifetimes) - Working with: unwrap, expect, ?, Option, Result, Path, PathBuf - File I/O operations in Rust (read, write, atomic writes) - CLI development with clap - Error handling patterns - Functions returning Option or Result that might fail silently - Path operations (canonicalize, file_name, parent, extension) - Deserializing JSON/YAML/TOML from external sources Key rules to apply: - Rule 35: Log before returning None (prevent silent failures) - Rule 36: Return Err for invalid input, not empty collections - Rule 37: Canonicalize paths at system boundaries - Rule 39: Every public method needs tests - Rule 40: Validate untrusted data at point of use - Rule 41: Audit ergonomic error suppressors (.

Run cargo audit and triage advisories by crate scope. Use whenever bumping dependencies, editing Cargo.toml or Cargo.lock, or investigating a RUSTSEC advisory. Also triggers on user phrases like "audit deps", "check CVEs", "are our dependencies safe".

Analyzes the variety and depth of assertions across test suites in any supported language. Use when the user asks to evaluate assertion quality, find shallow testing, identify tests with only trivial assertions, measure assertion diversity, or audit whether tests verify different facets of correctness. Produces metrics and actionable recommendations. Supports Rust and .NET (MSTest, xUnit, NUnit, TUnit). Also detects implicit assertions, panic/exception testing, mock verification, and framework-specific patterns. DO NOT USE FOR: writing new tests, detecting general anti-patterns, or fixing existing assertions — help the user directly with those.

Run cargo check after Rust file modifications to catch compile errors early
