## What is Rust Skills?

**Rust Skills** is a Claude Code plugin that transforms how AI assists with Rust development. Instead of giving surface-level answers, it traces through cognitive layers to provide **domain-correct architectural solutions**.

### The Problem

Traditional AI assistance for Rust:
```
User: "My trading system reports E0382"
AI: "Use .clone()"  ← Surface fix, ignores domain constraints
```

### The Solution

Rust Skills with meta-cognition:
```
User: "My trading system reports E0382"

AI (with Rust Skills):
├── Layer 1: E0382 = ownership error → Why is this data needed?
│       ↑
├── Layer 3: Trade records are immutable audit data → Should share, not copy
│       ↓
├── Layer 2: Use Arc<TradeRecord> as shared immutable value
│       ↓
└── Recommendation: Redesign as Arc<T>, not clone()
```

## Features

- **Meta-Cognition Framework**: Three-layer cognitive model (Domain → Design → Mechanics)
- **Real-time Information**: Fetch latest Rust versions and crate info via background agents
- **Dynamic Skills**: Auto-generate skills from your Cargo.toml dependencies
- **Domain Extensions**: FinTech, ML, Cloud-Native, IoT, Embedded, Web, CLI support
- **Coding Guidelines**: Complete Rust coding conventions and best practices

## Installation

### Method 1: Marketplace (Recommended)

Install from Claude Code Plugin Marketplace in two steps:

```bash
# Step 1: Add the marketplace
/plugin marketplace add ZhangHanDong/rust-skills

# Step 2: Install the plugin
/plugin install rust-skills@rust-skills
```

> **Note**: Step 1 only adds the marketplace (plugin source). Step 2 actually installs the rust-skills plugin with all features enabled.

### Method 2: NPX

Install using npx:

```bash
npx skills add ZhangHanDong/rust-skills
```

> ⚠️ **Note**: NPX installs skills only. Rust-skills is a **plugin architecture** that relies on agents, commands, and hooks for full functionality. For the complete experience, use Method 1 (Marketplace) or Method 3 (Full Plugin).

### Method 3: Full Plugin

This method enables **all features including hooks** for automatic meta-cognition triggering.

```bash
# Clone the repository
git clone https://github.com/ZhangHanDong/rust-skills.git

# Launch with plugin directory
claude --plugin-dir /path/to/rust-skills
```

### Method 4: Skills Only

This method only installs skills without hooks. You need to manually invoke skills.

```bash
# Clone and copy skills
git clone https://github.com/ZhangHanDong/rust-skills.git
cp -r rust-skills/skills/* ~/.claude/skills/
```

> ⚠️ **Note**: Without hooks, meta-cognition won't trigger automatically. You must manually call `/rust-router` or specific skills.

### Feature Comparison

| Feature | Marketplace | NPX | Full Plugin | Skills Only |
|---------|-------------|-----|-------------|-------------|
| All 31 Skills | ✅ | ✅ | ✅ | ✅ |
| Auto meta-cognition trigger | ✅ | ✅ | ✅ | ❌ |
| Hook-based routing | ✅ | ✅ | ✅ | ❌ |
| Background agents | ✅ | ✅ | ✅ | ✅ |
| Easy updates | ✅ | ✅ | ❌ | ❌ |

### Permission Configuration

Background agents require permission to run `agent-browser`. Configure in your project:

```bash
# Copy example config
cp /path/to/rust-skills/.claude/settings.example.json .claude/settings.local.json
```

Or create manually:

```bash
mkdir -p .claude
cat > .claude/settings.local.json << 'EOF'
{
  "permissions": {
    "allow": [
      "Bash(agent-browser *)"
    ]
  }
}
EOF
```

See [.claude/settings.example.json](.claude/settings.example.json) for reference.

### Other Platforms

- **OpenCode**: See [.opencode/INSTALL.md](.opencode/INSTALL.md)
- **Codex**: See [.codex/INSTALL.md](.codex/INSTALL.md)

## Dependent Skills

Rust Skills relies on these external tools for full functionality:

| Tool | Description | GitHub |
|------|-------------|--------|
| **actionbook** | MCP server for website action manuals. Used by agents to fetch structured web content (Rust releases, crate info, documentation). | [actionbook/actionbook](https://github.com/actionbook/actionbook) |
| **agent-browser** | Browser automation tool for fetching real-time web data. Fallback when actionbook is unavailable. | [vercel-labs/agent-browser](https://github.com/vercel-labs/agent-browser) |

## Meta-Cognition Framework

### Core Concept

**Don't answer directly. Trace through cognitive layers first.**

```
Layer 3: Domain Constraints (WHY)
├── Domain rules determine design choices
└── Example: Financial systems require immutable, auditable data

Layer 2: Design Choices (WHAT)
├── Design patterns and architectural decisions
└── Example: Use Arc<T> for shared immutable data

Layer 1: Language Mechanics (HOW)
├── Rust language features and compiler rules
└── Example: E0382 is a symptom of ownership design issues
```

### Routing Rules

| User Signal | Entry Layer | Trace Direction | Primary Skill |
|-------------|-------------|-----------------|---------------|
| E0xxx errors | Layer 1 | Trace UP ↑ | m01-m07 |
| "How to design..." | Layer 2 | Bidirectional | m09-m15 |
| "[Domain] app development" | Layer 3 | Trace DOWN ↓ | domain-* |
| Performance issues | Layer 1→2 | Up then Down | m10-performance |

## Skills Overview

### Core Skills
- `rust-router` - Master router for all Rust questions (invoked first)
- `rust-learner` - Fetch latest Rust/crate version info
- `coding-guidelines` - Coding conventions lookup

### Layer 1: Language Mechanics (m01-m07)

| Skill | Core Question | Triggers |
|-------|---------------|----------|
| m01-ownership | Who should own this data? | E0382, E0597, move, borrow |
| m02-resource | What ownership pattern fits? | Box, Rc, Arc, RefCell |
| m03-mutability | Why does this data need to change? | mut, Cell, E0596, E0499 |
| m04-zero-cost | Compile-time or runtime polymorphism? | generic, trait, E0277 |
| m05-type-driven | How can types prevent invalid states? | newtype, PhantomData |
| m06-error-handling | Expected failure or bug? | Result, Error, panic, ? |
| m07-concurrency | CPU-bound or I/O-bound? | async, Send, Sync, thread |

### Layer 2: Design Choices (m09-m15)

| Skill | Core Question | Triggers |
|-------|---------------|----------|

| m10-performance | Where's the bottleneck? | benchmark, profiling |
| m11-ecosystem | Which crate fits this task? | crate selection, dependencies |
| m12-lifecycle | When to create, use, cleanup? | RAII, Drop, lazy init |
| m13-domain-error | Who handles this error? | retry, circuit breaker |
| m14-mental-model | How to think about this correctly? | learning Rust, why |
| m15-anti-pattern | Does this pattern hide design issues? | code smell, common mistakes |

### Layer 3: Domain Constraints (domain-*)

| Skill | Domain | Core Constraints |
|-------|--------|------------------|
| domain-fintech | FinTech | Audit trail, precision, consistency |
| domain-ml | Machine Learning | Memory efficiency, GPU acceleration |
| domain-cloud-native | Cloud Native | 12-Factor, observability, graceful shutdown |
| domain-iot | IoT | Offline-first, power management, security |
| domain-web | Web Services | Stateless, latency SLA, concurrency |
| domain-cli | CLI | UX, config precedence, exit codes |
| domain-embedded | Embedded | No heap, no_std, real-time |

## Commands

| Command | Description |
|---------|-------------|
| `/rust-features [version]` | Get Rust version features |
| `/crate-info <crate>` | Get crate information |
| `/docs <crate> [item]` | Get API documentation |
| `/sync-crate-skills` | Sync skills from Cargo.toml dependencies |
| `/update-crate-skill <crate>` | Update specific crate skill |

## Dynamic Skills

Generate skills on-demand from your project dependencies:

```bash
# Enter your Rust project
cd my-rust-project

# Sync all dependencies
/sync-crate-skills

# Skills are created at ~/.claude/skills/{crate}/
```

### Features
- **On-demand generation**: Created from Cargo.toml dependencies
- **Local storage**: `~/.claude/skills/`
- **Version tracking**: Each skill records crate version
- **Workspace support**: Parses all workspace members
