ai-store

A curated collection of Agent Skills for Claude Code and compatible AI coding agents, organized by technology stack.

Each skill is a self-contained SKILL.md file that teaches the agent a specific workflow or set of best practices — from implementing .NET features and reviewing Angular code to writing Gherkin scenarios and refactoring safely. Skills are loaded automatically when relevant, or can be invoked explicitly by name.

The repository currently contains 36 skills in five categories:

Category	Skills	Focus
Angular	11	Angular 17+ development, testing, reviews, libraries
.NET	11	.NET/C# development, ASP.NET Core, EF Core, NuGet
General	8	Language-agnostic workflows: reviews, refactoring, BDD, docs
Java	4	Spring Boot, JUnit 5, Javadoc
TypeScript	2	Jest, RxJS

Installation

Skills are installed with the Skills CLI (npx skills). It requires Node.js and works with Claude Code, Codex, Cursor, OpenCode, and many other agents.

Use -g to install user-scoped (e.g. ~/.claude/skills/ for Claude Code, available in all projects). Without -g, skills are installed project-scoped into the current repository (e.g. .claude/skills/).

Install all skills

# User-scoped, for Claude Code, no prompts
npx skills add CreativeCodersTeam/ai-store -g -a claude-code -s '*' -y

# Interactive: pick skills and target agents from a list
npx skills add CreativeCodersTeam/ai-store

Install a single skill

npx skills add CreativeCodersTeam/ai-store -g -a claude-code -s dotnet-dev

Install a whole category

Point the CLI at a subfolder to install everything in it with one command:

# All 11 .NET skills
npx skills add CreativeCodersTeam/ai-store/skills/dotnet -g -a claude-code -s '*' -y

# All 11 Angular skills
npx skills add CreativeCodersTeam/ai-store/skills/angular -g -a claude-code -s '*' -y

The shorthand always resolves to the repository's default branch (main). To install from another branch, use the full URL form instead:

npx skills add https://github.com/CreativeCodersTeam/ai-store/tree/<branch>/skills/dotnet -g -a claude-code -s '*' -y

Useful flags

Flag	Description
-g, --global	Install user-scoped instead of into the current project
-a, --agent <agents...>	Target specific agents (e.g. claude-code, codex)
-s, --skill <names...>	Install specific skills by name; '*' installs all
-l, --list	List the skills a source offers without installing
--copy	Copy files instead of symlinking
-y, --yes	Skip all confirmation prompts

To preview what a source contains before installing:

npx skills add CreativeCodersTeam/ai-store --list

Manual installation

Skills are plain directories — you can also clone the repository and copy or symlink individual skills yourself:

git clone https://github.com/CreativeCodersTeam/ai-store.git

# User-scoped (all projects)
cp -R ai-store/skills/dotnet/dotnet-dev ~/.claude/skills/

# Or symlink, so `git pull` keeps the skill up to date
ln -s "$(pwd)/ai-store/skills/general/refactoring" ~/.claude/skills/refactoring

# Project-scoped (current repository only)
cp -R ai-store/skills/typescript/jest .claude/skills/

Restart Claude Code afterwards and run /skills to confirm the skills are loaded.

Every skill lives in skills/<category>/<skill-name>/SKILL.md. Some skills ship additional reference files or scripts alongside their SKILL.md.

Contributing

To add a new skill:

1. Create skills/<category>/<skill-name>/SKILL.md (add a new category folder if none fits).

2. Start the file with YAML frontmatter containing name and description:

   ---
   name: my-skill
   description: Use when ... — a precise trigger description so agents load the skill at the right moment.
   ---

3. Keep the skill self-contained; put larger reference material in files next to the SKILL.md.

4. Open a pull request.
