Tool 1: Anthropic Academy

What it is

Anthropic built and maintains a free course library at anthropic.skilljar.com. These are structured courses, not loose YouTube videos. You get progress tracking, quizzes, and completion certificates.

Who it’s for

Three types of people get the most out of this: complete beginners who want to understand how to use Claude for everyday work, developers who want to build on the API or connect Claude to external tools with MCP, and educators or team leads who want to roll out AI training for their organization.

Courses worth starting with

• Claude 101 — core features, everyday tasks, where to go next
• Claude Code 101 — getting Claude into your actual dev workflow
• Building with the Claude API — the full picture for developers
• Introduction to Model Context Protocol — how to connect Claude to external services using Python
• Introduction to subagents — how to delegate tasks and manage context in Claude Code

How to use it

Go to anthropic.skilljar.com, create a free account, and pick the track that matches where you are right now. If you have no idea where to start, Claude 101 takes maybe an hour and gives you the right mental model for everything else.

Tool 2: Anthropic’s Official Skills Library

What it is

The anthropics/skills GitHub repo is the official collection of Claude Code Skills. A Skill is a folder of markdown instructions and resources that Claude Code loads automatically when it’s relevant to the task you’re running.

What skills actually do

Think of them as permanent behavior upgrades for Claude Code. Instead of re-explaining your workflow every session, you drop a Skill into your project and Claude just knows how to handle that category of task. That might mean writing docs in your company’s format, running a specific type of code review, or following a particular analysis process.

Who it’s for

This one is squarely for people already using Claude Code. If you’re just getting started with Claude the chat product, bookmark this and come back once you’re running Claude Code regularly.

How to use it

1. Browse the skills/ folder in the repo to see what’s available
2. Clone or download the relevant Skill folder
3. Drop it into your project directory
4. Claude Code picks it up and applies it to matching tasks automatically

The repo also includes a template/ folder and a spec if you want to write your own Skills from scratch.

Tool 3: Awesome Claude Code Subagents

What it is

VoltAgent/awesome-claude-code-subagents is a community-maintained collection of over 100 Claude Code subagents. Each subagent is a specialized assistant scoped to a specific development task, things like code review, security auditing, writing tests, documentation, and more.

Skills vs. subagents — the difference

Skills modify how Claude behaves across a session. Subagents are separate focused agents you spawn to handle a specific job, then hand results back to your main conversation. The benefit is that you keep your main context clean while a dedicated agent does the heavy lifting on something narrow.

Who it’s for

Developers using Claude Code who want to stop burning context on repetitive or specialized tasks. Instead of asking your main Claude session to also be a security auditor, you delegate that to a subagent built specifically for it.

How to use it

The repo includes an install-agents.sh script that handles setup. From there, you browse by category or use the subagent catalog in tools/subagent-catalog/ to find what fits your workflow.

# Clone the repo
git clone https://github.com/voltagent/awesome-claude-code-subagents

# Run the install script
cd awesome-claude-code-subagents
bash install-agents.sh

The .claude/ folder in the repo shows you exactly how the agents are structured if you want to build or customize your own.

These three resources cover the full stack: learn how Claude works, extend it with Skills for your specific projects, and delegate specialized work to subagents without cluttering your main workflow. None of them cost anything. The only real cost is the time to set them up, and the Anthropic Academy courses make that time shorter than it would be otherwise.
