💡 What This Is & Why It Matters

Modern API development presents a challenge for AI coding agents: they often generate code based on outdated training data, leading to subtle but critical bugs. Awesome API Skills solves this problem.

The Problem

When AI agents like Claude Code, Cursor, or Gemini CLI write code for contemporary APIs without proper context, they frequently make mistakes:

❌ Outdated SDK Methods - Using deprecated API signatures from old training data
❌ Security Vulnerabilities - Parsing webhook payloads before signature verification
❌ Authentication Failures - Implementing deprecated middleware patterns
❌ Rate Limiting Errors - Making unbatched API calls in loops
❌ Type Safety Issues - Missing critical type definitions and schema validations

The Solution

Awesome API Skills provides 101 curated, schema-validated SKILL.md context files that teach AI agents:

• ✅ Current API Signatures - Latest SDK methods and endpoints
• ✅ Best Practices - Security, performance, and reliability patterns
• ✅ Common Pitfalls - What to avoid and how to handle edge cases
• ✅ Production Patterns - Real-world tested implementations
• ✅ Error Handling - How to gracefully handle failures

Simply copy a skill file into your agent's skill directory (.claude/skills/, .cursor/skills/, etc.), and your AI coding partner will generate production-ready code.

⚡ The Difference A Skill Makes

🔒 Stripe Webhook Verification

🔐 Clerk Auth Middleware

📧 Resend Batch Emailing

🚀 Quick Start

Installation Methods

Option 1: Copy Into Your Project (Simplest)

The easiest way to get started - no installation required:

# 1. Clone the repository (lightweight)
git clone --depth 1 https://github.com/ashish7802/awesome-api-skills.git

# 2. Copy the skill you need to your agent's skill directory

# For Claude Code
cp -r awesome-api-skills/skills/stripe ~/.claude/skills/
cp -r awesome-api-skills/skills/clerk ~/.claude/skills/

# For Cursor
cp -r awesome-api-skills/skills/stripe ~/.cursor/skills/
cp -r awesome-api-skills/skills/postgresql ~/.cursor/skills/

# For generic AI agent workspace
cp -r awesome-api-skills/skills/redis ~/agent-workspace/skills/

Then instruct your AI agent:

"Use the SKILL.md files in .claude/skills/ for all Stripe payment integration code"

Option 2: Monorepo & Local CLI Setup

How It Works

1. Skills are Organized - Each skill lives in skills/<skill-name>/
2. Metadata Defined - metadata.json describes relationships, versions, and categories
3. SKILL.md Documented - Comprehensive teaching files for AI agents
4. Validated Automatically - CI/CD ensures all skills match schema
5. Indexed for Search - Registry builds relationship graph
6. Served to Agents - Copy into agent skill directories as needed

🎯 Verification & Quality Standards

Every claim in this repository is backed by automated verification:

✅ Schema Validation

All 101 skills pass strict structural checks via packages/validator

✅ Automated Unit Tests

31+ assertions covering all core packages run in CI via Vitest

✅ Last Verified Metadata

Each skill includes a lastVerified timestamp documenting when SDK signatures were validated against vendor documentation

✅ Relationship Scoring

Skill connections use a transparent hybrid scoring model:

• Explicit declared edges (high confidence)
• Category matching
• Ecosystem compatibility
• Deployment platform alignment
• Semantic similarity (Jaccard index)

✅ CI/CD Pipeline

GitHub Actions automatically:

• Validates all skill schemas on push
• Runs test suite
• Builds documentation
• Updates search index
• Checks for outdated SDK signatures
