Senpi Getting Started Guide

Design and deploy multi-canister dapps. Covers inter-canister calls, canister factory pattern, async messaging pitfalls, bounded vs unbounded wait, and 2MB payload limits. Use when splitting an app across canisters, making inter-canister or cross-canister calls, or designing canister-to-canister communication. Do NOT use for single-canister apps.

Brad Frost's Atomic Design methodology for UI component hierarchies: atoms (indivisible elements), molecules (small groups of atoms), organisms (complex sections of molecules), and templates (page layouts). Enforces bottom-up composition (never skip levels), presentational components (data via props, events via callbacks, no data fetching), design tokens for all visual properties, and composition over inheritance. Use when building user interfaces, creating component libraries, organizing frontend code, designing form systems, or structuring any UI. Triggers on: "build a component", "component hierarchy", "design tokens", "presentational components", "composition over inheritance", "React/Vue/SwiftUI components", "atomic design". Applies to any UI framework.

Use this skill for processing and analyzing large tabular datasets (billions of rows) that exceed available RAM. Vaex excels at out-of-core DataFrame operations, lazy evaluation, fast aggregations, efficient visualization of big data, and machine learning on large datasets. Apply when users need to work with large CSV/HDF5/Arrow/Parquet files, perform fast statistics on massive datasets, create visualizations of big data, or build ML pipelines that don't fit in memory.

Generate dynamic social preview images using Next.js file conventions and the next/og library. Server-rendered JSX images cached at build time.

**Opt-in DSL path** for NocoBase app building. Use ONLY when the user explicitly asks for YAML / DSL / committed-to-git / `cli push` / spec files — e.g. "use the DSL reconciler", "I want YAML I can commit", "build this as a workspaces/ project". For any other UI authoring request (new page, new block, tweak an existing screen), default to `nocobase-ui-builder` instead — this reconciler is still in active development and has rough edges that the live-UI path avoids. When the user opts in: produces/changes files under `workspaces/<project>/`, supports new pages, menus, modules, whole systems, collections, tables, sub-tables, popups, dashboards, approval workflows, recordActions, and deploys them via `cli push`.

nginx C module performance optimization and reliability guidelines based on the official nginx development guide. This skill should be used when optimizing nginx C modules for throughput, latency, memory efficiency, and operational resilience. Triggers on tasks involving buffer optimization, connection tuning, shared memory contention, error recovery, timeout strategy, caching implementation, worker process tuning, or logging performance in nginx C modules.
