How do I install rust-skills?

Run these in Claude Code: /plugin marketplace add zhanghandong/rust-skills then /plugin install rust-skills@rust-skills. Then prompt normally.

Does rust-skills auto-invoke its skills?

Not yet. It is indexed on Flowy as a plain plugin. Request auto-invocation on its page and Flowy will route its skills for you as you prompt.

Yes. Flowy is free and open source, with nothing gated. You can read every skill in full before you install.

Rust Skills

中文 | 日本語

AI-powered Rust development assistant with meta-cognition framework

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

Rust Skills supports two installation modes:

Plugin Mode (Claude Code): Full features including hooks, agents, and auto meta-cognition
Skills-only Mode: Works with any coding agent that supports skills (Claude Code, Vercel AI, etc.)

Skills-only Install (Recommended)

The simplest way to get started. Works with any coding agent that supports skills, including Claude Code, Vercel's add-skills, and others.

Skills now include inline fallback logic — when agent files are not available, skills execute directly using built-in tools (actionbook, agent-browser, WebFetch).

Option A: NPX (Easiest)

npx skills add actionbook/rust-skills

Option B: CoWork CLI

Install via CoWork, a Rust-based skills management tool:

# Install CoWork
cargo install cowork

# Method 1: Direct install
cowork install actionbook/rust-skills

# Method 2: Config-based install (recommended for teams)
cowork config init                    # Create .cowork/Skills.toml
# Edit Skills.toml to add rust-skills (see below)
cowork config install                 # Install all configured skills

Skills.toml configuration:

[project]
name = "my-rust-project"

[skills.install]
rust-skills = "actionbook/rust-skills"

[security]
trusted_authors = ["ZhangHanDong"]

CoWork (co for short) provides version management, dependency resolution, lock files, and security auditing. See CoWork documentation for more details.

Option C: Manual Copy

git clone https://github.com/actionbook/rust-skills.git
cp -r rust-skills/skills/* ~/.claude/skills/

Note: Skills-only mode does not include hooks, so meta-cognition won't trigger automatically. You can manually call /rust-router or specific skills. Background agents fall back to inline execution automatically.

Claude Code Plugin Install (Full Features)

For Claude Code users who want the complete experience with hooks, background agents, and auto meta-cognition triggering.

Option A: Marketplace

# Step 1: Add the marketplace
/plugin marketplace add actionbook/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.

Option B: Full Plugin (Local)

# Clone the repository
git clone https://github.com/actionbook/rust-skills.git

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

Feature Comparison

Feature	Plugin (Marketplace)	Plugin (Local)	Skills-only (NPX/CoWork/Manual)
All 31 Skills	✅	✅	✅
Auto meta-cognition trigger	✅	✅	❌ (manual invoke)
Hook-based routing	✅	✅	❌
Background agents	✅	✅	✅ (inline fallback)
Easy updates	✅	❌	✅ (NPX/CoWork)
Works with other agents	❌	❌	✅

Permission Configuration

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

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

Or create manually:

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

See .claude/settings.example.json for reference.

Other Platforms

OpenCode: See .opencode/INSTALL.md
Codex: See .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
agent-browser	Browser automation tool for fetching real-time web data. Fallback when actionbook is unavailable.	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

AI-powered Rust development assistant with meta-cognition framework

What is Rust Skills?

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

Rust Skills supports two installation modes:

Plugin Mode (Claude Code): Full features including hooks, agents, and auto meta-cognition
Skills-only Mode: Works with any coding agent that supports skills (Claude Code, Vercel AI, etc.)

Skills-only Install (Recommended)

The simplest way to get started. Works with any coding agent that supports skills, including Claude Code, Vercel's add-skills, and others.

Skills now include inline fallback logic — when agent files are not available, skills execute directly using built-in tools (actionbook, agent-browser, WebFetch).

Option A: NPX (Easiest)

npx skills add actionbook/rust-skills

Option B: CoWork CLI

Install via CoWork, a Rust-based skills management tool:

# Install CoWork
cargo install cowork

# Method 1: Direct install
cowork install actionbook/rust-skills

# Method 2: Config-based install (recommended for teams)
cowork config init                    # Create .cowork/Skills.toml
# Edit Skills.toml to add rust-skills (see below)
cowork config install                 # Install all configured skills

Skills.toml configuration:

[project]
name = "my-rust-project"

[skills.install]
rust-skills = "actionbook/rust-skills"

[security]
trusted_authors = ["ZhangHanDong"]

CoWork (co for short) provides version management, dependency resolution, lock files, and security auditing. See CoWork documentation for more details.

Option C: Manual Copy

git clone https://github.com/actionbook/rust-skills.git
cp -r rust-skills/skills/* ~/.claude/skills/

Note: Skills-only mode does not include hooks, so meta-cognition won't trigger automatically. You can manually call /rust-router or specific skills. Background agents fall back to inline execution automatically.

Claude Code Plugin Install (Full Features)

For Claude Code users who want the complete experience with hooks, background agents, and auto meta-cognition triggering.

Option A: Marketplace

# Step 1: Add the marketplace
/plugin marketplace add actionbook/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.

Option B: Full Plugin (Local)

# Clone the repository
git clone https://github.com/actionbook/rust-skills.git

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

Feature Comparison

Feature	Plugin (Marketplace)	Plugin (Local)	Skills-only (NPX/CoWork/Manual)
All 31 Skills	✅	✅	✅
Auto meta-cognition trigger	✅	✅	❌ (manual invoke)
Hook-based routing	✅	✅	❌
Background agents	✅	✅	✅ (inline fallback)
Easy updates	✅	❌	✅ (NPX/CoWork)
Works with other agents	❌	❌	✅

Permission Configuration

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

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

Or create manually:

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

See .claude/settings.example.json for reference.

Other Platforms

OpenCode: See .opencode/INSTALL.md
Codex: See .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
agent-browser	Browser automation tool for fetching real-time web data. Fallback when actionbook is unavailable.	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

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
