Integrate the alpha markstream-angular renderer into Angular 20+ standalone apps, covering signals, streaming state, custom tags, and safe HTML defaults.

This skill enables developers to override Markstream node renderers and add trusted custom tags across Vue, React, Svelte, and Angular. It allows scoped or renderer-local mappings without replacing the parser. Useful for customizing built-in elements or rendering specific tags like thinking. It emphasizes security by treating custom tags as trusted input and maintaining safe HTML policies.

Integrate markstream-vue into Nuxt 3 or 4 with SSR-safe client boundaries, renderer modes, explicit CSS, and browser-only optional peers for streaming Markdown.

Integrate the beta markstream-svelte renderer into Svelte 5 or SvelteKit apps with runes, explicit CSS, smooth streaming, workers, and SSR-safe boundaries.

Integrate the markstream-vue renderer into plain Vue 3 apps: pick renderer modes (chat, docs, minimal), fenced-code rendering, smooth streaming state and cursor handling, long-message virtualization, scoped components, and safe HTML/Mermaid policies.

Integrate markstream-vue2 into Vue CLI or Webpack 4 projects with export-map-safe CSS, CDN worker fallbacks, and safe streaming markdown rendering defaults.

Integrate markstream-vue2 into a Vue 2 plus Vite project with bundled worker imports, CSS layer ordering, Composition API compatibility, and safe streaming markdown defaults for chat or history rendering.

Provides cross-language patterns for developing memory-safe systems code. This skill covers crucial concepts like RAII, ownership models, smart pointers, and robust resource management. It is essential for preventing common vulnerabilities such as use-after-free, memory leaks, and ensuring reliable resource handling across complex systems.

This skill analyzes data warehouses to identify stale, unused, or redundant tables that increase storage costs. It classifies waste patterns, computes safety tiers, and provides actionable cleanup recommendations. Supports Snowflake, BigQuery, Redshift, and Databricks. Ideal for reducing cloud infrastructure expenses and optimizing data governance.

This skill guides users on writing Python code within n8n Code nodes, focusing on standard library usage. It details critical limitations regarding external packages, offering workarounds for HTTP requests and data analysis. Users learn when to prefer Python over JavaScript and how to handle specific syntax requirements safely within the n8n environment.

Safely select and switch between multiple n8n MCP instances (production, staging, etc.) before performing operations. Prevents silent misrouting by verifying the target instance, especially for credential writes. Ensures correct environment targeting for workflow automation tasks.

This guide provides expert patterns for implementing secure, full-stack authentication in Next.js using Supabase. It covers essential architectural components, including setting up separate browser and server clients, utilizing middleware for route protection and session refreshing, handling OAuth callbacks, and implementing auth operations safely via Server Actions and Server Components. Essential knowledge for building secure, modern web applications.
