name: check description: Check Rust code compilation and lint with clippy. Use when checking if code compiles, running clippy, validating changes, or before building. allowed-tools: Bash(just --list:), Bash(just check:), Bash(just check-rs:), Bash(just check-crate:), Bash(just clippy:), Bash(just clippy-crate:)

Code Check and Lint Skill

Check Rust code compilation and run clippy linter.

Commands

Check all Rust code compiles:

Copyjust check-rs

Alias: just check

Check specific crate:

Copyjust check-crate <crate-name>

Lint all Rust code:

Copyjust clippy

Lint specific crate:

Copyjust clippy-crate <crate-name>

Checking with Features

Many crates have optional features (like ffi for FFI bindings) that should be checked.

Check with FFI feature:

Copyjust check-rs --features ffi
just clippy --features ffi

Check with all features:

Copyjust check-rs --all-features
just clippy --all-features

Per-crate feature checks:

Copyjust check-crate <crate-name> --features ffi
just clippy-crate <crate-name> --all-features

Workflow

1. Format code → /format
2. Check crate compilation → just check-crate <crate-name>
3. Lint crate with clippy → just clippy-crate <crate-name>
4. Fix all warnings, repeat 2-3 until crate is clean
5. Check whole project → just check-rs
6. Lint whole project → just clippy
7. Fix any remaining warnings
8. Check with FFI features → just check-rs --features ffi and just clippy --features ffi
9. Check with all features → just check-rs --all-features and just clippy --all-features
10. Fix any feature-specific warnings

Error Handling

• Compilation errors → Fix reported issues, format, re-check
• Clippy warnings → Fix all warnings (mandatory), format, re-run

Critical Rules

• NEVER use cargo check or cargo clippy directly - use just commands
• FIX ALL WARNINGS - warnings are not acceptable
• Format before checking - run /format first
