What is FastAgent?

FastAgent is a curated collection of professional plugins for Claude Code that extend your AI coding assistant with specialized agents, skills, and commands. Our approach is simple: pick only what you need, avoid token bloat, and get better results.

Why FastAgent?

• 🎯 Focused & Efficient: Each plugin is laser-focused on specific technologies or roles
• 💰 Token-Conscious: Only load what you need - save tokens, save costs
• 🔧 Modular Design: Mix and match plugins based on your workflow
• 📦 Easy Installation: One command to add capabilities
• 🚀 Production-Ready: Battle-tested patterns and best practices

Our Plugin Philosophy

We organize plugins into three tiers to make it easy to choose what you need:

🌟 Essential Tier

Broad-spectrum plugins that benefit most developers. These cover fundamental workflows like code review, debugging, and refactoring.

Who should use: Everyone

👤 Role Tier

Role-based plugins combining multiple technologies and workflows for specific job functions.

Who should use: Developers in specialized roles

🔧 Tech Tier

Technology-specific plugins for deep expertise in particular tools and frameworks. Choose the ones matching your stack.

Who should use: Developers working with specific technologies

Quick Start

1. Install Claude Code

Make sure you have Claude Code installed.

2. Add the FastAgent Marketplace

# In Claude Code, run:
/plugin marketplace add armanzeroeight/agents-skills

3. Browse and Install Plugins

# Open the plugin browser
/plugin

# Or install directly
/plugin install <plugin-name>@fastagent-marketplace

4. Start Using

Once installed, agents and skills activate automatically based on your work context. Commands are available via slash commands.

Available Plugins

🌟 Essential Tier (6 plugins)

🔧 Tech Tier (18 plugins)

👤 Role Tier (4 plugins)

How It Works

Agents = Strategy

Agents make high-level architectural decisions and choose the right approach. They focus on the "what" and "why".

Example: The Code Reviewer agent decides review scope, prioritizes issues, and determines severity levels.

Skills = Tactics

Skills handle specific operations with focused, step-by-step instructions. They focus on the "how".

Example: The Code Review Practices skill provides detailed guidance on conducting effective reviews.

Commands = Quick Actions

Commands are user-invoked shortcuts for frequently-used prompts.

Example: /quick-review triggers a fast code review of specific files.

The Magic: Automatic Delegation

Agents automatically delegate to skills when needed. You get strategic thinking at the top level and tactical execution when required - all without manual intervention.

Team Configuration (Optional)

For automatic plugin installation across your team, add to your project's .claude/settings.json:

{
  "extraKnownMarketplaces": {
    "fastagent-marketplace": {
      "source": {
        "source": "github",
        "repo": "armanzeroeight/agents-skills"
      }
    }
  },
  "enabledPlugins": [
    "developer-toolkit@fastagent-marketplace",
    "terraform-toolkit@fastagent-marketplace"
  ]
}

When team members trust the repository, plugins install automatically.

Usage Examples

Using Agents

Agents activate automatically based on context:

# Code review
> Review my recent changes

# Debugging
> Help me debug this error

# Infrastructure design
> Design a Terraform module for our VPC

Or invoke explicitly:

> Use the code-reviewer agent to check my PR
> Ask the iac-architect agent about module design

Using Skills

Skills are invoked automatically by agents or Claude when relevant:

# Triggers terraform-module-scaffolder skill
> Create a new Terraform module for S3 buckets

# Triggers code-review-practices skill
> What should I look for in this code review?

Using Commands

Commands are user-invoked with slash syntax:

# Quick code review
/quick-review

# Debug trace
/debug-trace

Managing Plugins

View Installed Plugins

/plugin

Enable/Disable Plugins

# Disable without uninstalling
/plugin disable <plugin-name>@fastagent-marketplace

# Re-enable
/plugin enable <plugin-name>@fastagent-marketplace

Uninstall Plugins

/plugin uninstall <plugin-name>@fastagent-marketplace

Update Marketplace

/plugin marketplace update fastagent-marketplace

Token Efficiency

One of FastAgent's core principles is token efficiency. Here's how we help you save:

Only Load What You Need

Instead of one massive plugin with everything, choose specific plugins:

# ❌ Don't load everything
# One giant plugin with all technologies

# ✅ Load only what you use
/plugin install terraform-toolkit@fastagent-marketplace  # Only if you use Terraform
/plugin install kubernetes-toolkit@fastagent-marketplace  # Only if you use K8s

Progressive Disclosure

Skills use progressive disclosure - detailed documentation is loaded only when needed:

skill/
├── SKILL.md          # Loaded always (concise)
└── references/       # Loaded only when needed (detailed)

Focused Skills

Each skill does one thing well, keeping context lean:

• ✅ terraform-state-manager - State operations only
• ✅ terraform-cost-estimator - Cost analysis only
• ❌ terraform-everything - Too broad, wastes tokens
