10 Claude Code Skills That Replaced My Boilerplate Folders

I used to keep a folder of boilerplate code. Auth templates. Stripe integration files. Docker configs.

I do not do that anymore. Here are the 10 Claude Code skills that replaced them.

What Is a Claude Code Skill?

A skill is a markdown file Claude Code reads before writing code. It gives Claude full context about your preferences, patterns, and requirements — so the output is production-ready, not generic.

You invoke a skill with a slash command:

/auth → full authentication system
/pay  → Stripe billing setup

Claude reads the skill, asks clarifying questions, then outputs complete implementations.

The 10 Skills

1. /auth — Authentication System

Asks: OAuth providers? Session or JWT? Role-based access needed?

Outputs: Complete auth implementation with login, logout, session management, and route protection. Supports NextAuth, Supabase Auth, or custom JWT.

Time saved: ~6 hours

2. /pay — Stripe Billing

Asks: One-time or subscription? How many plans? Trial period?

Outputs: Stripe integration with checkout, webhook handler, subscription management, and customer portal link.

Time saved: ~4 hours

3. /deploy — Docker + CI/CD

Asks: Which cloud provider? Do you need staging environment? Auto-deploy on push?

Outputs: Dockerfile, docker-compose, GitHub Actions workflow, and cloud-specific deploy config.

Time saved: ~3 hours

4. /test — Test Generation

Asks: Unit tests, integration tests, or both? Which testing framework?

Outputs: Full test suite for any function or module you point it at. Covers happy path, edge cases, and error conditions.

Time saved: ~2 hours per module

5. /api — REST API Scaffolding

Asks: REST or GraphQL? Authentication required? Which database?

Outputs: Complete CRUD endpoints with validation, error handling, and OpenAPI spec.

Time saved: ~3 hours

6. /db — Database Schema

Asks: Describe your data model in plain English.

Outputs: Prisma schema (or SQLAlchemy models, Drizzle schema — your choice) with migrations, relationships, and indexes.

Time saved: ~2 hours

7. /email — Transactional Emails

Asks: Which email provider? What triggers emails?

Outputs: Email templates, send functions, and trigger hooks for welcome, password reset, subscription events.

Time saved: ~2 hours

8. /rate-limit — Rate Limiting

Asks: Per user or per IP? What limits? Redis or in-memory?

Outputs: Rate limiting middleware with configurable windows and automatic cleanup.

Time saved: ~1.5 hours

9. /analytics — Usage Tracking

Asks: What events matter? Do you need a dashboard?

Outputs: Event tracking hooks, aggregation queries, and a simple dashboard component.

Time saved: ~3 hours

10. /error-handling — Error Boundaries + Logging

Asks: Which logging service? Client errors too?

Outputs: Global error handler, structured logging setup, Sentry or similar integration, and user-facing error UI.

Time saved: ~2 hours

Total: 28+ Hours Saved Per Project

That is a conservative estimate. On a real project these overlap and compound.

More importantly, the code is consistent. No more guessing which auth pattern you used in the last project. The skill remembers.

Each skill is a plain markdown file. You own it. Modify it for your stack.

The Bigger Picture

Skills are the missing layer between raw Claude capability and production output.

Without a skill, Claude writes code that works. With a skill, Claude writes code that fits your stack, follows your patterns, and does not need three rounds of revision.
