# Kling AI Skill Pack

30 production-ready skills for [Kling AI](https://klingai.com/) -- the leading AI video generation platform by Kuaishou Technology. Covers the full API surface: text-to-video, image-to-video, video extension, lip sync, effects, camera control, motion brush, virtual try-on, and Kolors image generation.

**API Base URL:** `https://api.klingai.com/v1`
**Auth:** JWT tokens from Access Key (AK) + Secret Key (SK), 30-minute expiry, HS256 signing.

## One-Pager

### The Problem

Kling AI's API uses JWT authentication (not simple API keys), has async task-based generation (submit, poll, download), temporary CDN URLs that expire, mutually exclusive feature sets for image-to-video, and model versions with different capability matrices. Getting all of this right requires reading across fragmented docs and multiple community examples.

### The Solution

30 Claude Code skills with real Kling AI API endpoints, real request/response shapes, real Python and Node.js code, real error codes, and real cost calculations. Every skill uses the actual `https://api.klingai.com/v1` base URL and actual JWT authentication patterns. No placeholder code.

### What's Included

| Category | Skills | Coverage |
|----------|--------|----------|
| **Onboarding** | 6 | Auth setup, hello world, model catalog, SDK patterns, T2V basics, pricing |
| **Operations** | 6 | Error diagnosis, debug logging, rate limits, job monitoring, prod checklist, version migration |
| **CI/CD & Pipelines** | 6 | Webhooks, batch processing, async workflows, cloud storage, CI/CD, reference architecture |
| **Enterprise** | 6 | Team access, cost controls, usage analytics, content policy, audit logging, compliance review |
| **Advanced** | 6 | Image-to-video, video extension, camera control, style/effects, performance tuning, pitfalls |

### Stack

| Component | Technology |
|-----------|-----------|
| API | REST over HTTPS, JWT auth (HS256) |
| Models | kling-v1 through kling-v2-6, Kolors v1.5-v2.1 |
| Languages | Python 3.8+ (PyJWT, requests), Node.js 18+ (jsonwebtoken) |
| Features | T2V, I2V, video extend, lip sync, effects, camera control, motion brush, virtual try-on |
| Pricing | Credit-based: 10 credits/5s standard, 35 credits/5s professional |

### Key Differentiators

- **Real JWT auth code** -- not "set your API key" placeholder, but actual `jwt.encode()` with correct headers, payload, and auto-refresh
- **Actual API endpoints** -- every skill uses `https://api.klingai.com/v1/videos/text2video`, `/image2video`, `/video-extend`, `/effects`, `/lip-sync`
- **Complete task lifecycle** -- submit, poll with adaptive backoff, handle succeed/failed states, download, store
- **Cost-aware** -- credit calculations for every model/mode/duration combo including the 5x audio multiplier
- **Production patterns** -- connection pooling, rate limiting, budget guards, batch queues, webhook fallback
