Code Cleaning Skills

Language and framework-specific patterns for writing clean, idiomatic code. Load the appropriate skill BEFORE working on code in that language.

Available Skills

Skill	Extension	Use When
@typescript	.ts, .tsx	Pure functional TypeScript - discriminated unions, branded types, composition
@rust	.rs	Rust idioms - ownership, Option combinators, error handling, trait patterns
@tokio	.rs + async	Async Rust - spawning, channels, structured concurrency
@svelte	.svelte	Svelte 5 runes + SvelteKit 2 - reactivity, load functions, form actions

Auto-Detection

Detect language from file extensions and load skills:

.rs          → @rust (+ @tokio if async)
.ts, .tsx    → @typescript
.svelte      → @svelte + @typescript

Usage

With code-cleaner agent

The agent identifies the language and loads relevant skills automatically:

@code-cleaner Review the changes in src/

With code review

Load language skills to enhance review depth:

/codex-review  # Reviews against principles
@rust          # Load Rust idioms for deeper review

Standalone

Reference skills directly for language-specific guidance:

How should I structure this TypeScript module? @typescript

Skill Layering

When cleaning code, load in order:

1. Quality principles (@principles) — Universal design rules
2. Language skill (@rust, @typescript) — Language-specific idioms
3. Framework skill (@tokio, @svelte) — Runtime-specific patterns

Each layer adds more specific patterns on top of general principles.
