Diagnose and fix Rust borrow checker and lifetime errors. Paste compiler errors and code — get structured analysis and fixes.

Write Rust code with awareness of known AI pitfalls — ownership, lifetimes, async, module integration, idiomatic patterns. Use when writing new Rust code or implementing features.

Scaffold a new Rust project with correct structure, dependencies, and configuration. Handles workspace, library, and binary crate setup.

Review Rust code for correctness, safety, idiomatic patterns, and common AI-generated code smells. Use when reviewing Rust code quality or before merging.

Hyprland/Steam gaming launch-option workflow for this NixOS machine. Use whenever the user asks for best settings for a game, Steam/Proton launch options, gamescope, MangoHud/MangoApp, VRR/adaptive sync, fullscreen game focus/hover/cursor issues, Rocket League-like settings, or says to optimize a game such as Black Ops 3 on Hyprland.

Use when file search or content grep is needed in a git-indexed directory and the fff MCP server is available.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Rust coding skill for the teleport-rs project. MUST be used whenever writing, editing, or reviewing any Rust code (.rs files) in this workspace — including proc macros, the export binary, library code, tests, and Cargo.toml changes. Triggers on: Rust implementation, adding procedures, error types, Axum handlers, Specta types, inventory registration, macro expansion, Cargo dependency changes, or any discussion about how to write Rust code in this project.
