What are Claude Code Skills?

Claude Code Skills are reusable prompt templates stored as markdown files in your project's .claude/skills/ directory. They let you codify best practices and common workflows into slash commands that Claude follows consistently.

How do I create a Claude Code Skill?

Create a markdown file in .claude/skills/ with instructions for Claude. The filename becomes the command name — for example, .claude/skills/code-review.md can be invoked with /code-review during a Claude Code session.

Can I share skills with my team?

Yes. Skills stored in .claude/skills/ can be committed to version control so every team member has access to the same standardized workflows. You can also organize skills into subdirectories by category.

What is the difference between project and global skills?

Project skills (.claude/skills/) are specific to the current project and are committed to git. Global skills (~/.claude/skills/) are personal skills available across all your projects.

Overview

A collection of Agent Skills for several scopes in software development, computer science and engineering.

Skills are specialized instruction sets that extend the capabilities of coding agents for specific tasks, automatically activating when needed.

Available skills

Simulink Creator

Name: simulink-creator

Description: Simulink Creator is a tool that allows users to create and edit Simulink models programmatically using MATLAB code. It provides a set of functions and APIs that enable users to build Simulink models, add blocks, connect them, and configure their properties through code. This skill is useful for automating the creation of Simulink models, generating models from data or specifications, and integrating Simulink with other tools and workflows.

Prompt Example:

code

Build a Simulink model that simulates a cruise control system. The vehicle dynamics are modeled as a transfer function 10 / (s^2 + 3s). Use a PID controller with P=2, I=0.5, D=0.1. Include a Step reference at t=1s with amplitude 25 (target speed in m/s), log the output to workspace, and display both the reference and output on the same Scope.

Installation & Usage

Claude Code (CLI)

Recommended: Install all agent skills using the plugin marketplace:

bash

# (Step 1) Add the marketplace to Claude Code
/plugin marketplace add hariseldon86/skills

# (Step 2) Install all Agent Skills
/plugin install hariseldon86-skills@hariseldon86-skills

This installs all the skills in one command. Skills automatically activate when Claude detects relevant tasks.

Manual installation

Agent Skills are supported by Claude Code, Claude.ai, Cursor, VS Code, GitHub Copilot, Gemini CLI, Antigravity, OpenAI Codex, and many more.

Integration and connection may vary by plan and platform. Generally you should:

bash

# Clone the repository
git clone https://github.com/HariSeldon86/skills.git

# Copy all skills to your skills directory (claude, vscode, antigravity, etc.)
cp -r skills/skills/* YOUR_PROJECT/.claude/skills/
cp -r skills/skills/* YOUR_PROJECT/.github/skills/
cp -r skills/skills/* YOUR_PROJECT/.agent/skills/

# Or copy one specific skill only
cp -r skills/skills/simulink-creator YOUR_PROJECT/.claude/skills/simulink-creator
cp -r skills/skills/simulink-creator YOUR_PROJECT/.github/skills/simulink-creator
cp -r skills/skills/simulink-creator YOUR_PROJECT/.agent/skills/simulink-creator

Install & Usage
