fastapi-zero-to-hero
★ 1Complete FastAPI API development framework for Python. Provides comprehensive assistance for building APIs with routing, authentication (JWT, OAuth2, Better Auth), Pydantic models, database integration, and deployment using uv package manager. Use when users ask to build FastAPI applications, implement authentication, create API endpoints, or develop backend services in Python.
openai-api
★ 1Build with OpenAI's stateless APIs - Chat Completions (GPT-5, GPT-4o), Embeddings, Images (DALL-E 3), Audio (Whisper + TTS), and Moderation. Includes Node.js SDK and fetch-based approaches for Cloudflare Workers.Use when: implementing chat completions with GPT-5/GPT-4o, streaming responses with SSE, using function calling/tools, creating structured outputs with JSON schemas, generating embeddings for RAG (text-embedding-3-small/large), generating images with DALL-E 3, editing images with GPT-Image-1, transcribing audio with Whisper, synthesizing speech with TTS (11 voices), moderating content (11 safety categories), or troubleshooting rate limits (429), invalid API keys (401), function calling failures, streaming parse errors, embeddings dimension mismatches, or token limit exceeded.
stripe
This skill should be used when the user asks to "integrate Stripe", "add payments", "create subscriptions", "handle webhooks", "usage-based billing", "per-seat pricing", "tiered plans", "checkout session", "customer portal", "sync Stripe data", "Stripe Sync Engine", "payment processing", "MRR analytics", "revenue reporting", or mentions 'Stripe', 'subscription', 'billing', 'webhook', 'checkout', 'metered billing', 'payment intent', 'stripe schema'. Automatically triggers for payment, subscription, and billing analytics work.
