World-class database schema design - data modeling, migrations, relationships, and the battle scars from scaling databases that store billions of rowsUse when "database schema, data model, migration, prisma schema, drizzle schema, create table, add column, foreign key, primary key, uuid, auto increment, soft delete, normalization, denormalization, one to many, many to many, junction table, polymorphic, enum type, index strategy, database, schema, migration, data-model, prisma, drizzle, typeorm, postgresql, mysql, sqlite" mentioned.
Securely execute untrusted Python, Node.js, Bun, Deno, and Bash code in sandboxed Docker containers.
Complete Convex development mastery — functions (queries, mutations, actions, HTTP actions), schema design, index optimization, argument/return validation, authentication, security patterns, error handling, file storage, scheduling, crons, aggregates, OCC handling, denormalization, TypeScript best practices, and production-ready code organization. The definitive Convex skill. Use when building any Convex backend: writing functions, designing schemas, optimizing queries, handling auth, adding real-time features, setting up webhooks, scheduling jobs, managing file uploads, or reviewing/fixing Convex code. Triggers on: convex, query, mutation, action, ctx.db, defineSchema, defineTable, v.id, v.string, v.object, withIndex, ConvexError, internalMutation, httpAction, ctx.scheduler, ctx.storage, OCC, convex best practices, convex functions, convex schema, convex performance, "how do I do X in Convex".
Fastify high-performance Node.js framework. Covers routing, plugins, validation, and serialization. Use when building fast Node.js APIs. USE WHEN: user mentions "Fastify", "fastify", "TypeBox", "schema validation", asks about "fast Node.js framework", "high-throughput API", "JSON schema validation", "performance-critical backend", "plugin-based architecture" DO NOT USE FOR: Enterprise DI patterns - use `nestjs` instead, Minimalist approach - use `express` instead, Edge runtimes - use `hono` instead, Deno - use `oak` or `fresh` instead
ASR (Automatic Speech Recognition) — enhanced speech-to-text built on Doubao large model, with audio preprocessing, denoising, and extended analysis capabilities. Async API. Choose this skill when: - Input is a video file (mp4/mov/mkv) — auto-extracts audio track - Audio needs denoising before recognition - File exceeds 512MB or 5 hours (no size limit) - Audio source is a TOS internal path (tos://bucket/key) - Need structured JSON output with timestamped utterances and metadata - Need speaker diarization, emotion/gender detection, speech rate, or sensitive word filtering Supports 99 languages, multiple formats (wav/mp3/m4a/aac/flac/ogg/mp4/mov/mkv), and auto language detection.
Add security protection to a server-side route or endpoint — rate limiting, bot detection, email validation, and abuse prevention. Works across frameworks including Next.js, Express, Fastify, SvelteKit, Remix, Bun, Deno, NestJS, and Python (Django/Flask). Use this skill when the user wants to protect an API route, form handler, auth endpoint, or webhook from abuse, even if they describe it as "add rate limiting," "block bots," "prevent brute force," or "secure my endpoint" without mentioning Arcjet specifically. Uses the Arcjet CLI (`npx @arcjet/cli` or `brew install arcjet`) for authentication, site/key setup, remote rule management, and traffic verification.
Guideline for designing, implementing, and verifying secure TypeScript and JavaScript applications following OWASP Top 10 best practices. Use when the user wants to: (1) review TypeScript or JavaScript code for security vulnerabilities, (2) design a secure Node.js, Deno, or browser application architecture, (3) implement security features (authentication, authorization, cryptography, input validation), (4) audit npm/yarn/pnpm dependencies for known vulnerabilities, (5) create security checklists or verification plans, (6) fix security bugs or harden existing TypeScript or JavaScript code, (7) set up security testing and static analysis (ESLint security plugins, Semgrep, Snyk), or (8) handle any TypeScript/JavaScript security concern including injection prevention, prototype pollution, XSS protection, SSRF prevention, secrets management, and secure deployment.
Build type-safe APIs with Hono for Cloudflare Workers, Deno, Bun, Node.js. Routing, middleware, validation (Zod/Valibot), RPC, streaming (SSE), WebSocket, security (CSRF, secureHeaders). Use when: building Hono APIs, streaming SSE, WebSocket, validation, RPC. Troubleshoot: validation hooks, RPC types, middleware chains, JWT verify algorithm required (v4.11.4+), body consumed errors.
Video processing toolkit. Use when user wants to: - Download videos from YouTube or other sites - Remove silence from videos - Trim, cut, or extract segments from videos - Extract audio from video files - Enhance or denoise audio - Replace audio track in a video - Change video playback speed - Concatenate multiple videos - Generate transcripts/captions (VTT) - Generate video descriptions, timestamps, or context cards - Upload videos to YouTube or Bunny.net CDN - Post social updates to X (Twitter) or LinkedIn - Get video metadata (duration, resolution, codec)
Deployment patterns from Kubernetes to serverless and edge functions. Use when deploying applications, setting up CI/CD, or managing infrastructure. Covers Kubernetes (Helm, ArgoCD), serverless (Vercel, Lambda), edge (Cloudflare Workers, Deno), IaC (Pulumi, OpenTofu, SST), and GitOps patterns.
AI Video Enhancement - Upscale video resolution, improve quality, denoise, sharpen, enhance low-quality videos to HD/4K. Supports local video files, remote URLs (YouTube, Bilibili), auto-download, real-time progress tracking.
Use this skill when deploying edge functions, writing Cloudflare Workers, configuring CDN cache logic, optimizing latency with edge-side processing, or building serverless-at-the-edge architectures. Triggers on edge functions, CDN rules, Cloudflare Workers, Deno Deploy, Vercel Edge Functions, Lambda@Edge, cache headers, geo-routing, and any task requiring computation close to the user.
