Welcome to the Ultimate AI Skill Library. We analyzed over 1,200+ raw skills from top official repositories across the globe (Vercel, Anthropic, HashiCorp, Microsoft, OpenAI, Letta, Composio, Stripe, Supabase) and compressed them into a perfectly engineered, hyper-specialized vault of 17 Mega-Skills and 8 Master Roles.

This library gives your AI agents extreme precision, bypassing general hallucinations entirely, and enforcing industry-standard architecture straight into their context windows.

Quickstart: The Smart CLI

Our interactive CLI module gives you absolute control over what skills are deployed and auto-configures your IDE.

npx @harshitj183/ai-skills <command>

Available Commands:

1. init – Installs the full library quietly by default (perfect for letting your AI agent select skills dynamically).
   • npx @harshitj183/ai-skills init -i (Interactive picker)
   • npx @harshitj183/ai-skills init -r frontend_expert.md -s react_best_practices.md (CLI filtering)
2. configure – Auto-detects and writes the rules file for your specific IDE (.cursorrules, .windsurfrules, CLAUDE.md, etc.).
3. update – Safely pulls the newest official skills from the registry without overwriting your custom skills.
4. create <skill_name> – Scaffolds a new highly-optimized custom Mega-Skill inside smart-instructions/custom/.

Architecture: What is Included?

graph TD;
    A[SKILL.md - Master Rulebook] --> B[Roles Directory];
    A --> C[Mega-Skills Directory];
    B --> D(Backend Expert);
    B --> E(Frontend Expert);
    B --> F(System Engineer);
    C --> G(Supabase Architecture);
    C --> H(Cloudflare Edge Deploy);
    C --> I(OpenAI Strict Models);

1. The Core Engine (SKILL.md)

The central controller. This file dictates how the AI behaves: commanding aggressive accuracy, strictly typed JSON generation, minimal boilerplate, and routing prompts automatically to the correct roles.

2. The 8 Master Roles (roles/)

Eliminate the need for extensive prompting. Just tag a role file.

• backend_expert.md, frontend_expert.md, gpt5_core.md, product_manager.md, security_auditor.md, technical_writer.md, ui_ux_designer.md, wisdom_extractor.md

3. The 17 Mega-Skills (skills/)

Give your AI absolute technical dominance over specific frameworks.

| Category | Skills Included | Example Technologies | | :--- | :--- | :--- | | Infrastructure | mcp_master.md, hashicorp_terraform.md, azure_graph_integrator.md, antigravity_mastery.md | Terraform, Azure AD, MCP Servers | | Frontend & Apps | react_best_practices.md, react_native_performance.md, playwright_testing.md | React 19, Expo, Playwright | | Backend & APIs | supabase_architect.md, stripe_integration.md, openai_structured_outputs.md | PostgreSQL, Stripe, OpenAI | | Orchestration | composio_integrator.md, sanity_architecture.md, vercel_cloudflare_deploy.md, github_automation.md | Next.js, Cloudflare, Sanity CMS | | AI Reasoning | prompt_reasoning_trees.md, letta_agent_memory.md, anthropic_documents.md | Claude, ReAct, Memory Persistence |

🏛️ AI History Tracking (New!)

Version 2.2.5 introduces a built-in History tracking system. When you initialize the library, it creates a private history/ folder in your project that allows AI agents to maintain a timeline of their actions, achievements, and technical decisions.

• ai_activity_log.md: Tracks every task performed by AI.
• project_timeline.md: High-level roadmap achievements.
• milestones.md: Key technical breakthroughs.

Usage Across AI Platforms

Run the installer once in your project root, then configure your preferred AI tool:

npx @harshitj183/ai-skills init

This places all files inside smart-instructions/ in your project. Your .gitignore is automatically updated.

1. Cursor IDE

Rename smart-instructions/SKILL.md to .cursorrules at your project root. Every Cursor chat will automatically follow the rules.

mv smart-instructions/SKILL.md .cursorrules

Or reference individual skills surgically:

"@react_best_practices.md implement a new dashboard."

2. Claude Code (CLI)

Claude Code auto-reads CLAUDE.md from your root. Copy the contents:

cp smart-instructions/SKILL.md CLAUDE.md

Or tell Claude directly: "Read smart-instructions/SKILL.md as your core directive."

3. ChatGPT (Web / Custom GPT)

Option A — Custom Instructions:

• Go to Settings → Custom Instructions → paste contents of SKILL.md

Option B — Project Knowledge (ChatGPT Plus):

• Create a new Project → Upload SKILL.md and any skill files you need

Option C — Chat Upload:

• Attach SKILL.md directly to your conversation as a file

4. GitHub Copilot (VS Code)

Copy instructions to the Copilot-specific file:

cp smart-instructions/SKILL.md .github/copilot-instructions.md

Or reference in chat: "#file:smart-instructions/react_best_practices.md refactor this component."

5. Gemini / Antigravity (Google)

Tell Antigravity: "Read smart-instructions/SKILL.md and act according to the Roles inside." Antigravity automatically detects skill files in your workspace.

6. Windsurf IDE (Codeium)

Windsurf supports .windsurfrules file:

cp smart-instructions/SKILL.md .windsurfrules

7. Zed Editor

Add to Zed's AI assistant context:

• Settings → Assistant → System Prompt → paste SKILL.md contents

8. Cline / Continue.dev (VS Code Extensions)

Place the skill files in .clinerules or .continuerules:

cp smart-instructions/SKILL.md .clinerules

For Continue.dev, add to config.json under systemMessage.

9. Aider (Terminal AI)

aider --read smart-instructions/SKILL.md

10. Any LLM API (OpenAI, Groq, Mistral, Llama)

Paste SKILL.md content as your system message in the API call:

{ role: "system", content: fs.readFileSync("smart-instructions/SKILL.md", "utf8") }
