name	rust-development
description	Build and review Rust applications, libraries, CLIs, and systems code. Use for ownership, lifetimes, async, error handling, unsafe review, performance, and FFI.

Rust Development

Purpose

Support Rust engineering with attention to correctness, API design, safe concurrency, and explicit unsafe boundaries.

Workflow

1. Identify toolchain, edition, crate layout, and target platform.
2. Keep public APIs small and errors meaningful.
3. Prefer safe abstractions; isolate and document unsafe.
4. Check ownership and lifetime complexity against actual requirements.
5. Verify with cargo test, cargo clippy, cargo fmt, and benchmarks where useful.

Checklist

• Result and error context.
• Trait bounds, generics, and public API stability.
• Async runtime boundaries and blocking calls.
• Send/Sync, Arc/Mutex/RwLock usage, and deadlocks.
• FFI, unsafe invariants, alignment, and aliasing.
• Feature flags and dependency surface.

Output

Return:

• API and ownership summary.
• Safety and concurrency risks.
• Verification commands.
• Compatibility notes.
