Use this skill when building real-time data pipelines, stream processing jobs, or change data capture systems. Triggers on tasks involving Apache Kafka (producers, consumers, topics, partitions, consumer groups, Connect, Streams), Apache Flink (DataStream API, windowing, checkpointing, stateful processing), event sourcing implementations, CDC with Debezium, stream processing patterns (windowing, watermarks, exactly-once semantics), and any pipeline that processes unbounded data in motion rather than data at rest.
Build Airflow 3.1+ plugins that embed FastAPI apps, custom UI pages, React components, middleware, macros, and operator links directly into the Airflow UI. Use this skill whenever the user wants to create an Airflow plugin, add a custom UI page or nav entry to Airflow, build FastAPI-backed endpoints inside Airflow, serve static assets from a plugin, embed a React app in the Airflow UI, add middleware to the Airflow API server, create custom operator extra links, or call the Airflow REST API from inside a plugin. Also trigger when the user mentions AirflowPlugin, fastapi_apps, external_views, react_apps, plugin registration, or embedding a web app in Airflow 3.1+. If someone is building anything custom inside Airflow 3.1+ that involves Python and a browser-facing interface, this skill almost certainly applies.
Control which data each viewer sees in an embedded Domo dashboard/card via server-side programmatic filters and dataset switching. Covers the OAuth → embed token flow, standard filters, SQL filters (OR/BETWEEN/LIKE), per-dataset targeting, datasetRedirects for multi-tenant architectures, and token size limits. Use for any per-viewer, per-role, or per-tenant data restrictions at embed time. Not for client-side JS API filtering (use cap-de-jsapi-filters).
Implements and customize Syncfusion .NET MAUI Calendar (SfCalendar) control. Use when implementing calendar functionality, date selection (single, multiple, range), or calendar views (month, year, decade, century). Covers date restrictions (min/max dates, EnablePastDates, SelectableDayPredicate), calendar customization, events (ViewChanged, SelectionChanged, Tapped), and header/footer customization.
Learn to implement and configure the Syncfusion WPF NumericUpdown (UpDown) control for numeric value input. Use when creating numeric input fields with spin buttons, value restrictions, number formatting, and cultural support. Includes guidance for getting started, managing values, formatting numbers, styling, and advanced configurations.
Implements the Syncfusion WPF DatePicker (SfDatePicker) control for touch-friendly date selection. Use this when adding date input controls, customizing date picker appearance, formatting date displays, or restricting date ranges in WPF applications. Covers installation, date formatting, styling, customization, value management, and event handling.
Inspect and configure NocoBase roles, system permissions, route permissions, table global permissions, table independent permissions, field permissions, and row scopes via MCP. Use when users want to grant, restrict, debug, or audit ACL behavior in a NocoBase app.
Implement masked text input controls in WinForms applications. Use this skill whenever the user needs to create input fields with format masks (phone numbers, IP addresses, dates, currency), validate formatted input, restrict data entry to specific patterns, or configure how user input behaves with mask constraints.
NestJS framework best practices and production patterns. Use whenever working with NestJS — creating modules, controllers, services, DTOs, guards, interceptors, pipes, middleware, or building REST/GraphQL/microservice APIs. Also use when setting up authentication, authorization, validation, queues, health checks, WebSockets, caching, or any @nestjs/* package. Even for simple NestJS tasks, this skill ensures correct import paths, proper decorator usage, and production-ready patterns. Covers NestJS v11 with Express v5, native JWT auth, Zod validation, Keyv caching, and Suites testing.
Use when connecting a REST API to an MCP client, setting up mcp-openapi-proxy, exposing an OpenAPI-backed navigator/executor MCP server, or authenticating with OIDC/static tokens for API proxying.
Use this skill whenever the user wants Claude to directly interact with their Obsidian vault — reading a note or daily note, writing or appending content, searching vault contents, counting or listing notes, managing tasks, moving or renaming files, finding orphaned notes or broken links. Without this skill, Claude has no way to access vault data or execute vault operations. Treat any request that implies "go into my vault and do X" as a trigger — the user is asking Claude to act, not to explain. Also trigger for vault automation, CLI scripting, or cron-based workflows involving Obsidian, managing sync history, querying Bases, restoring file versions via history, managing bookmarks, or running JavaScript against the Obsidian API. Skip for pure conceptual questions: how Obsidian's GUI works, navigating settings menus, theme or plugin installation via the UI, iCloud/third-party sync conflicts, general Dataview query syntax, keyboard shortcuts, or parsing vault files with external scripts — anything where the user needs an explanation rather than Claude performing a vault operation.
Implements Syncfusion WinUI TimePicker (SfTimePicker) control for time input and selection in desktop applications. Use this when building time input controls, time selection interfaces, or dropdown time spinners. This skill covers time restrictions, time formatting, dropdown spinner customization, and time selection for scheduling and appointment scenarios in WinUI applications.
