Summary

This emulator lets you test Google OAuth 2.0, OpenID Connect, Gmail, Calendar, and Drive integration without hitting real Google APIs. You get a local server that mimics authorization flows, token exchange, PKCE, and the major Google services. Seed it with test users, OAuth clients, calendar events, Gmail messages, and Drive files so your tests are repeatable. It works with google-auth-library, Auth.js, and Passport by pointing them at localhost instead of accounts.google.com. Honestly a lifesaver if you've ever burned through API quotas during development or needed to test edge cases like workspace domains without creating actual Google accounts. Supports strict client validation when you configure OAuth clients, otherwise accepts any client_id for quick prototyping.

find-hypertable-candidates

timescale/pg-aiguide

Use this skill to analyze an existing PostgreSQL database and identify which tables should be converted to Timescale/TimescaleDB hypertables. **Trigger when user asks to:** - Analyze database tables for hypertable conversion potential - Identify time-series or event tables in an existing schema - Evaluate if a table would benefit from Timescale/TimescaleDB - Audit PostgreSQL tables for migration to Timescale/TimescaleDB/TigerData - Score or rank tables for hypertable candidacy **Keywords:** hypertable candidate, table analysis, migration assessment, Timescale, TimescaleDB, time-series detection, insert-heavy tables, event logs, audit tables Provides SQL queries to analyze table statistics, index patterns, and query patterns. Includes scoring criteria (8+ points = good candidate) and pattern recognition for IoT, events, transactions, and sequential data.

Guide for advanced Next.js App Router patterns including Route Handlers, Parallel Routes, Intercepting Routes, Server Actions, error boundaries, draft mode, and streaming with Suspense. CRITICAL for server actions (action.ts, actions.ts files, 'use server' directive), setting cookies from client components, and form handling. Use when requirements involve server actions, form submissions, cookies, mutations, API routes, `route.ts`, parallel routes, intercepting routes, or streaming. Essential for separating server actions from client components.

nextjs-client-cookie-pattern

wsimmonds/claude-nextjs-skills

Pattern for client components calling server actions to set cookies in Next.js.

Use when building features like authentication, preferences, or session management where client-side triggers need to set/modify server-side cookies.

nocobase-ui-builder

nocobase/skills

INTERNAL CONTINUATION ONLY. Never select this skill from a raw user UI request. Use it only after nocobase-portal-manage has already resolved exactly one enabled Portal and confirmed portalType=no-code, or has proved the runtime has capabilities.multiPortal === false. Portal count or `isDefault` marker alone never enables this skill. It authors NocoBase Modern UI pages, blocks, menu items, fields, actions, layouts, reactions, and AI employee placements through backend flow-surfaces via nb api. Unresolved UI requests go to nocobase-portal-manage first; a sole AI Portal is handed off automatically for source-code implementation. Hand off AI employee lifecycle work to nocobase-ai-employee and explicit DSL, YAML, git, or cli push workflows to nocobase-dsl-reconciler. It does not handle ACL, data modeling, workflow orchestration, browser reproduction, page error postmortems, Portal lifecycle, AI Portal source-code UI, or non-Modern page navigation.
