What Are Skills?

Skills are structured instruction sets that give AI assistants specialized capabilities. Each skill is a self-contained folder with:

• A SKILL.md file — the core instructions and decision logic
• Optional references/ — detailed frameworks, templates, and checklists
• Optional scripts/ — executable code for file manipulation, testing, or automation

Instead of writing long prompts every time, you point your AI to a skill and it instantly gains expert-level capability in that domain.

Quick Start

Option 1: AI Coding Editor (Recommended)

If your editor supports a skills/instructions folder (e.g., Claude Code, Antigravity, Cursor, etc):

1. Clone the repo

   git clone https://github.com/Agilkannan/skills.git

2. Point your editor to the skills folder

   • Set the cloned folder as your project workspace, or
   • Copy individual skill folders into your editor's designated skills directory

3. Start using skills — the AI will automatically detect and apply relevant skills based on your requests.

Option 2: Web-Based AI (ChatGPT, Gemini, etc.)

1. Open the skill's SKILL.md file on GitHub
2. Copy the contents and paste into your conversation as context
3. For referenced files — if the SKILL.md mentions files in references/, paste those too for full capability

Option 3: Cherry-Pick Individual Skills

Don't need all 17? Just copy the folders you want:

# Example: grab just the business skills
cp -r skills/market-researcher /your/workspace/
cp -r skills/business-strategist /your/workspace/

How Skills Work

Anatomy of a Skill

skill-name/
├── SKILL.md           # Core instructions (< 500 lines)
├── LICENSE.txt         # Apache 2.0 license
├── references/         # Deep-dive frameworks and templates
│   ├── framework-a.md
│   └── framework-b.md
├── scripts/            # Executable automation code

└── assets/             # Static resources (fonts, images, etc.)

Progressive Disclosure

Skills are designed to be token-efficient. The AI loads context in three levels:

Level	What Loads	When
1. Metadata	Skill name + description (from YAML frontmatter)	Always — used for skill matching
2. SKILL.md body	Core instructions, decision trees, process flows	When the skill is activated
3. References & Scripts	Detailed templates, frameworks, code	Only when specifically needed

This means the AI doesn't waste context on 500 lines of financial modeling templates unless you actually ask about financial projections.

Compatibility

Platform	Support Level	How to Use
Antigravity/VS Code	✅ Native	Skills auto-detected from workspace
Cursor / Windsurf	✅ Native	Place in project rules or instructions folder
ChatGPT	⚡ Manual	Paste SKILL.md content into conversation
Gemini	⚡ Manual	Paste SKILL.md content into conversation
Perplexity	⚡ Manual	Paste SKILL.md content into conversation
Any LLM	⚡ Manual	Skills are plain Markdown — works with anything

Creating Your Own

Use the built-in skill-creator skill to build new skills:

1. Describe what capability you want
2. The skill-creator walks you through: planning → structure → writing → packaging
3. Output: A complete skill folder ready to use

Key Principles

• SKILL.md under 500 lines — keep it focused; move details to references/
• Decision trees over paragraphs — help the AI pick the right approach fast
• Progressive disclosure — load heavy references only when needed
• Imperative form — write instructions as commands: "Analyze the market" not "You should analyze the market"
• Anti-patterns section — explicitly list what the skill should NOT do
