Appwrite TypeScript SDK skill. Use when building browser-based JavaScript/TypeScript apps, React Native mobile apps, or server-side Node.js/Deno backends with Appwrite. Covers client-side auth (email, OAuth, anonymous), database queries, file uploads, real-time subscriptions, and server-side admin via API keys for user management, database administration, storage, and functions.
Use when designing databases for data-heavy applications, making schema decisions for performance, choosing between normalization and denormalization, selecting storage/indexing strategies, planning for scale, or evaluating OLTP vs OLAP trade-offs. Also use when encountering N+1 queries, ORM issues, or concurrency problems.
Use when writing server-side code with Supabase — Edge Functions, Hono apps, webhook handlers, or any backend that needs Supabase auth and client creation. Trigger whenever the user imports from `@supabase/server`, mentions `supabase/server`, Supabase Edge Functions, or needs server-side auth (JWT verification, API key validation, CORS handling) with Supabase. Also trigger when you see legacy patterns in existing code — `Deno.serve`, `createClient(Deno.env.get('SUPABASE_URL'))`, imports from `esm.sh/@supabase`, `deno.land/std` serve, or usage of `SUPABASE_ANON_KEY` / `SUPABASE_SERVICE_ROLE_KEY` — these indicate code that should be migrated to this package.
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.
Guidelines for building edge-first, high-performance APIs with Hono and TypeScript for Cloudflare Workers, Deno, Bun, and Node.js
Tiny and elegant HTTP client based on the Fetch API for modern browsers, Node.js, Bun, and Deno
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
Comprehensive Supabase development expert covering Edge Functions, database schema management, migrations, PostgreSQL functions, and RLS policies. Use for any Supabase development including TypeScript/Deno Edge Functions, declarative schema management, SQL formatting, migration creation, database function authoring with SECURITY INVOKER, and RLS policy implementation with auth.uid() and auth.jwt().
Look up metadata for any Injective token or denom. Resolves native tokens (INJ), Peggy ERC-20 bridged tokens (USDT, USDC, WETH), IBC assets (ATOM, OSMO), TokenFactory tokens, and EVM ERC-20s to their human-readable symbol, decimals, and type. Also supports sending tokens between addresses and depositing/withdrawing from trading subaccounts. Requires the Injective MCP server to be connected.
Dual Stacking enrollment operations on Stacks — earn BTC-denominated rewards (paid in sBTC) by holding sBTC. Check enrollment status and APR data, enroll with a single contract call (no lockup, minimum 10,000 sats sBTC), opt out, and query earned rewards by cycle. Write operations require an unlocked wallet.
Firebase gives you a complete backend in minutes - auth, database, storage, functions, hosting. But the ease of setup hides real complexity. Security rules are your last line of defense, and they're often wrong. Firestore queries are limited, and you learn this after you've designed your data model. This skill covers Firebase Authentication, Firestore, Realtime Database, Cloud Functions, Cloud Storage, and Firebase Hosting. Key insight: Firebase is optimized for read-heavy, denormalized data. I
