Postgres performance optimization and best practices from Supabase. Use this skill when writing, reviewing, or optimizing Postgres queries, schema designs, or database configurations.
Use when doing ANY task involving Supabase. Triggers: Supabase products (Database, Auth, Edge Functions, Realtime, Storage, Vectors, Cron, Queues); client libraries and SSR integrations (supabase-js, @supabase/ssr) in Next.js, React, SvelteKit, Astro, Remix; auth issues (login, logout, sessions, JWT, cookies, getSession, getUser, getClaims, RLS); Supabase CLI or MCP server; schema changes, migrations, security audits, Postgres extensions (pg_graphql, pg_cron, pg_vector).
Build and deploy Firebase Data Connect backends with PostgreSQL. Use for schema design, GraphQL queries/mutations, authorization, and SDK generation for web, Android, iOS, and Flutter apps.
Initialize a new Convex backend from scratch with schema, auth, and basic CRUD operations. Use when starting a new project or adding Convex to an existing app.
Audit and optimize Convex application performance, covering hot path reads, write contention, subscription cost, and function limits. Use when a Convex feature is slow, reads too much data, writes too often, has OCC conflicts, or needs performance investigation.
Set up Convex authentication with proper user management, identity mapping, and access control patterns. Use when implementing auth flows.
Plan and execute Convex schema migrations safely, including adding fields, creating tables, and data transformations. Use when schema changes affect existing data.
Design and build Convex components with clear boundaries, isolated state, and app-facing wrappers. Use when creating a new Convex component, extracting reusable backend logic into one, or packaging Convex functionality for reuse across apps.
Skill for integrating Better Auth - the comprehensive TypeScript authentication framework.
Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".
Sets up, manages, and executes queries against Cloud Firestore database instances. You MUST unconditionally activate this skill if you plan to use Firestore in any way. Use when listing or creating Firestore databases, configuring security rules, designing data models, writing client SDK queries, or checking indexes.
Routing skill for Convex work in this repo. Use when the user explicitly invokes the `convex` skill, asks which Convex workflow or skill to use, or says they are working on a Convex app without naming a specific task yet. Do not prefer this skill when the request is clearly about setting up Convex, authentication, components, migrations, or performance.
