Documentation reference for using Browser Use Cloud — the hosted API and SDK for browser automation. Use this skill whenever the user needs help with the Cloud REST API (v2 or v3), browser-use-sdk (Python or TypeScript), X-Browser-Use-API-Key authentication, cloud sessions, browser profiles, profile sync, CDP WebSocket connections, stealth browsers, residential proxies, CAPTCHA handling, webhooks, workspaces, skills marketplace, liveUrl streaming, pricing, or integration patterns (chat UI, subagent, adding browser tools to existing agents). Also trigger for questions about n8n/Make/Zapier integration, Playwright/ Puppeteer/Selenium on cloud infrastructure, or 1Password vault integration. Do NOT use this for the open-source Python library (Agent, Browser, Tools config) — use the open-source skill instead.
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.
Guide to using the Syncfusion WPF CalendarEdit control for date selection and navigation. Use this skill whenever the user needs to implement calendar functionality, select dates, restrict date ranges, customize calendar appearance, or work with multi-date selection. Essential for building date picker interfaces, booking systems, scheduling applications, and any WPF project requiring calendar controls.
Turbo pipeline operations reference — lifecycle commands (pause, resume, restart, delete), pipeline states, checkpoint behavior, streaming vs job-mode differences, CLI syntax for `inspect`/`logs`, TUI shortcuts, and error pattern lookup. Triggers on: 'how do I pause/restart/delete', 'will deleting lose my data', 'what does this error mean', 'inspect TUI shortcuts'. For interactive diagnosis of a broken pipeline, use /turbo-doctor.
Install, configure, and operate the Firebase CLI (firebase-tools) for all Firebase services. Use when you need to deploy to Firebase Hosting, Cloud Functions, Firestore, Realtime Database, Cloud Storage, Extensions, App Hosting, or run the Firebase Emulator Suite. Triggers on: firebase deploy, firebase init, firebase emulators, firebase hosting, firebase functions, firebase firestore, firebase database, firebase auth import, firebase remote config, firebase app distribution, firebase extensions, firebase apphosting, firebase cli, firebase-tools, deploy firebase, firebase preview channel, firebase login, firebase serve.
Mailgun (Sinch) platform help — developer-first transactional email API and SMTP relay with inbound routing, webhooks, and Mailgun Optimize deliverability tools. Use when sending transactional email via Mailgun API or SMTP, configuring domains or DNS (DKIM/SPF), setting up inbound email routing, managing webhooks or templates, using Mailgun Optimize for inbox placement testing, or working with the Mailgun REST API. Do NOT use for general email deliverability strategy (use /sales-deliverability), cross-platform email marketing (use /sales-email-marketing), or email open/click tracking strategy (use /sales-email-tracking).
Trigger: Call this skill when the problem is complex, has multiple conflicting factors, unclear priorities, or you don't know what to solve first; common signals include trade-off, bottleneck, unknown root cause, unclear priority order, and mutual restraint between multiple problems. Trigger when a problem contains competing forces, unclear priorities, or no obvious entry point. Use this skill to identify contradictions, isolate the principal contradiction, classify its nature, and choose the right response.
[Pragmatic DDD Architecture] Guide for Server and Client components in Next.js App Router. Use when creating any .tsx file under presentation/components/, pages, or layouts — also when deciding whether to add "use client" to an existing component, passing data from a Server Component to a Client Component, composing Server content inside a Client slot, handling the VO serialization boundary, creating Compound Components, separating logic for Mobile/Desktop screens, or styling with `cva` and `cn`. Covers: Server vs Client decision, async Server Component patterns, creating getSession callbacks for Use Cases, Client Component restrictions, toBranded() boundary pattern, children slot composition, and props interface rules. Depends on 'use-cases' and 'server-actions'.
Umbrella skill for agent work discipline across development, analysis, and documentation: inspect the repo before restructuring, keep durable truth in repo artifacts instead of chat memory, co-evolve specs/design/steering/user docs with code, apply sound coding patterns, verify work honestly, avoid shortcuts, work efficiently with subagents without hallucinating, and keep moving through the next concrete work item when the human is away. References cover coding patterns, AI-authored code review, and artifact co-evolution. Trigger when the user asks for workflow discipline, coding patterns, doc/artifact maintenance, code review of AI-authored code, project hygiene, execution guardrails, repo normalization, or when a task risks drifting across architecture, storage, specs, continuity, or tooling boundaries.
MUST activate before editing ANY file under uiBundles/*/src/ for visual or UI changes to an EXISTING app — pages, components, sections, layout, styling, colors, fonts, navigation, animations, or any look-and-feel change. Use this skill when modifying pages, components, layout, styling, or navigation in an existing UI bundle app. Activate when the project contains appLayout.tsx, routes.tsx, src/pages/, src/components/, or global.css. This skill contains critical project-specific conventions (appLayout.tsx shell, shadcn/ui components, Tailwind CSS, Salesforce base-path routing, module restrictions) that override general knowledge. Without this skill, generated code will use wrong imports, break routing, or ignore project structure. Do NOT use when creating a new app from scratch (use building-ui-bundle-app instead).
Follow this sub-process for code optimization — handle tasks where 'behavior remains unchanged but structure changes' (structure / performance / readability). Shift single-module internal optimization from 'AI random refactoring' to 'first scan to generate a checklist, confirm each item with the user, execute step by step according to the method library, and obtain manual approval for each step'. Trigger scenarios: When the user mentions phrases like 'optimize / refactor / rewrite / split / poor performance / too long code' without any accompanying behavior changes. Do not handle new requirements (route to feature), bugs (route to issue), or cross-module architecture restructuring (route to architecture + decisions).
· Design/review HTTP APIs for FastAPI, Express, NestJS: REST, OpenAPI, pagination, OAuth/JWT. Triggers: 'fastapi', 'express', 'nestjs', 'openapi', 'pagination', 'idempotency'. Not for schemas (use databases).
