| description | Maintain high code quality through formatting, linting, static analysis, and clean code principles. Use for rustfmt, clippy, cargo audit, code reviews, refactoring, and quality gates. |
Unified skill for Rust code quality and clean code development.
./scripts/code-quality.sh fmt # Format check
./scripts/code-quality.sh clippy --workspace # Lint with clippy
./scripts/code-quality.sh audit # Security audit
./scripts/code-quality.sh check # Run all quality gates
./scripts/quality-gates.sh # Full gates (coverage 90%)
| Check | Command | Target |
|---|---|---|
| Format | ./scripts/code-quality.sh fmt | 100% compliant |
| Lint | ./scripts/code-quality.sh clippy --workspace | Zero warnings |
| Audit | cargo audit | No known vulnerabilities |
| Coverage | cargo llvm-cov --html | >=90% |
| Docs | cargo doc --no-deps | All public APIs |
| Dimension | Focus |
|---|---|
| Structure | Files <500 LOC, clear modules |
| Error Handling | Custom Error, Result, ? operator (no unwrap) |
| Async | spawn_blocking for CPU work, no blocking in async |
| Testing | >=90% coverage, AAA pattern, cargo nextest + doctests |
| Security | Parameterized SQL, env vars, no hardcoded secrets |
SOLID: Single Responsibility, Open-Closed, Liskov Substitution, Interface Segregation, Dependency Inversion
DRY/KISS/YAGNI: Extract common code, simple solutions, build what's needed now
| Bad | Fix |
|---|---|
| Excessive clone | Use borrowing or Arc |
| Unnecessary unwrap | Use ? operator |
| Deep nesting | Extract methods |
| Large functions | Split (<50 LOC) |
| Deadlocks | Release locks before .await |
cargo tree -d | grep -cE "^[a-z]" # Count duplicates (target: <100)
cargo machete && cargo shear # Find unused deps
