Development
Implements the Syncfusion .NET MAUI Navigation Drawer (SfNavigationDrawer) component. Use for navigation drawers, sliding drawers, side menus, hamburger menus, or drawer panels in .NET MAUI apps. Covers drawer positioning (left/right/top/bottom), animations (SlideOnTop/Push/Reveal), content management, swipe gestures, and events.
Implements the Syncfusion .NET MAUI Numeric Entry control. Use for numeric input with validation, formatting (currency, percentage, decimal), value increment/decrement buttons, or range restrictions. Ideal for price inputs, quantity selectors, percentage calculators, or numeric data entry with custom formats.
Implements Syncfusion® .NET MAUI Polar Charts (SfPolarChart) for visualizing data in polar coordinates. Use when working with polar charts, radar charts, spider charts, web charts, or circular data visualization. Ideal for displaying data in terms of values and angles, creating line or area series in polar layouts, or comparing multiple data series radially.
Implements Syncfusion® .NET MAUI Pyramid Chart (SfPyramidChart) for visually representing hierarchical, proportional, and parts-to-whole data using pyramid-shaped segments. Use this for pyramid charts, hierarchical data visualization, proportional data display, or segment-based charts. This skill covers installation, data binding, legends, tooltips, data labels, appearance customization, and gradients.
Themes and styles Syncfusion .NET MAUI components. Use with SyncfusionThemeResourceDictionary, MaterialLight, MaterialDark, CupertinoLight, CupertinoDark, visual themes, or theme switching. Covers theme customization, color overrides, theme keys, dark mode, light mode, and branding.
Persists task and asset state across retries and DAG runs using Airflow 3.3's AIP-103 key/value stores (`task_state_store`, `asset_state_store`) and the crash-safe `ResumableJobMixin`. Use when the user asks about task state store, checkpointing in tasks, persisting state across retries, job IDs surviving worker crashes, watermarks, asset metadata, resumable tasks, crash-safe operators, or "what's new in Airflow 3.3". Also use proactively when reading a DAG that uses Variables or XCom for intra-task coordination state (flag the anti-pattern), or when reviewing any DAG that submits a job to an external system (Databricks, Snowflake, BigQuery, Redshift, Spark, dbt Cloud, EMR, AWS Batch, etc.) and waits for it to finish, whether as one submit-and-wait operator or split into submit + sensor/polling tasks; covers `wait_for_termination`, `deferrable`, `durable`, and hand-rolled polling sensors. State-persistence pieces require Airflow 3.3+; submit+poll architecture guidance applies on any version.
Route protection with beforeLoad, redirect()/throw redirect(), isRedirect helper, authenticated layout routes (_authenticated), non-redirect auth (inline login), RBAC with roles and permissions, auth provider integration (Auth0, Clerk, Supabase), router context for auth state.
Expert knowledge for Azure Service Bus development, including troubleshooting, best practices, decision-making, architecture and design patterns, limits and quotas, security, configuration, integrations and coding patterns, and deployment. Use when securing with Entra/SAS, configuring queues/topics, using sessions/forwarding, JMS/AMQP integration, or geo-DR, and for other Azure Service Bus-related development tasks. Not for Azure Event Hubs (use azure-event-hubs), Azure Queue Storage (use azure-queue-storage), Azure Notification Hubs (use azure-notification-hubs), or Azure Relay (use azure-relay)
Guides developers building Datadog Apps with TypeScript, React, and the @datadog/apps scaffolder and CLI. Use when a user wants to scaffold, run, debug, upgrade, build, upload, or publish a Datadog App, set up CI/CD, use OAuth or API/application key auth, trigger or poll Workflow Automation from a backend function, choose DDSQL or Action Catalog for backend data access, or query app datastores with DDSQL, including backend function troubleshooting.
Use when the user or project explicitly adopts hexagonal (ports and adapters) architecture—a README, CLAUDE.md, or ADR that says so is the opt-in. Once a project has opted in, load this for every code change in it, not only architecture work—a new feature, a transport or SDK swap, a bug fix, or a small business-rule change to a function that still calls an SDK directly; load it alongside tdd, never instead of it, and follow its Before You Write Code section before editing. Implements TypeScript ports, driving/driven adapters, dependency inversion, and domain isolation. Do NOT infer hexagonal architecture from a generic adapter, interface, test seam, or isolation request in a project that has not opted in.
Guides shipping a web app to the Meta VR and Horizon OS Store as a PWA/TWA — both 2D windowed panels and immersive WebXR/VR. Covers building the web app (IWSDK for WebXR, any responsive PWA for 2D), Vercel deploy, web app manifest + icons, the WebXR-only auto-enter-session step, choosing 2D vs immersive mode in @meta-quest/bubblewrap-cli, keystore/Digital-Asset-Links, and ovr-platform-util Store upload. Use before any IWSDK/WebXR build, PWA packaging, bubblewrap, or Horizon Store upload work.
Use when you want to expose an n8n workflow as a tool the coding agent can call. Two cases. (1) Wrap n8n API capabilities the MCP doesn''t natively expose: folder CRUD, tag rename/delete, instance metadata, credential creation. (2) Expose a general-purpose workflow as an agent tool: a workflow that calls a third-party API, runs business logic, or does any task you want the agent to invoke. Triggers on "expose as MCP tool", "build a tool for my agent", "I need to know X" where X isn''t an MCP tool, "create folder", "rename tag", or any capability gap.
Core Regle form validation in Vue 3 — setup with `useRegle`, the reactive `r$` object, validation properties, displaying errors, and modifiers. Use when adding or editing Regle forms, binding `v-model` to `r$.$value`, or reading `$error`/`$errors`/`$invalid`/`$validate`/`$reset`. For validation rules see regle-rules; for advanced patterns see regle-advanced.
Audit a page's rendering strategy and JavaScript dependency — diff raw HTML against the rendered DOM to measure how much primary content, links, headings, and JSON-LD exist only after JS executes; classify CSR-only / SSR / SSG / ISR, and emit framework-specific guidance. Module M4. Feeds both the Search SEO and AI Visibility scores
Implements and configure Syncfusion .NET MAUI Autocomplete (SfAutocomplete) control for intelligent text input with suggestions. Use when implementing autocomplete, autosuggest, type-ahead search, smart search, or filtered dropdowns in .NET MAUI applications. Covers data binding, filtering modes, custom search logic, AI-powered search, multi-selection with tokens, and UI customization.
Implements Syncfusion® .NET MAUI Chat (SfChat) control in .NET MAUI applications. Use when working with chat interfaces, messaging UI, conversational interfaces, chat bubbles, or message threads. Covers message types (text, image, calendar, card), data binding, events, suggestions, typing indicators, time breaks, and swiping actions.
Sets up and configures Syncfusion .NET MAUI components. Use when setting up, configuring, installing, or licensing Syncfusion .NET MAUI applications. Covers installation (NuGet, installers), licensing (generation, registration, errors), themes (Material, Cupertino, customization), AI service integration (Azure OpenAI, Claude, Gemini, DeepSeek, Groq), and package upgrades.
Implements Syncfusion® .NET MAUI Radial Gauge (SfRadialGauge) components. Use when working with radial gauges, circular gauges, speedometers, temperature monitors, meter gauges, or circular data visualization in .NET MAUI applications. This skill covers installation, axis configuration, ranges, pointer types (needle, shape, content, range), annotations, and animation.
Implements Syncfusion .NET MAUI Rich Text Editor (SfRichTextEditor) for WYSIWYG text editing with formatting, images, tables, hyperlinks, and code blocks. Use when building rich text editors, document editors, email composers, blog post editors, or messaging apps with formatting. Covers text styling, toolbar formatting, toolbar grouping with IsGrouped overlay menus, text transformation (UPPERCASE/lowercase), block-schema binding (TValue="Schema"), images, tables, hyperlinks, code blocks, HTML output, and the public GetText() method for plain-text extraction.
Create and configure a Twilio account from scratch. Covers free trial signup, trial limitations, getting credentials (Account SID and Auth Token), buying a phone number, verifying recipient numbers for trial use, SDK installation, first API call, subaccount management (creation, inheritance, credential isolation, limits), and enabling specific products (AI Assistants, Conversations, Verify, ConversationRelay, WhatsApp). Use this skill before any other Twilio skill if you do not yet have a Twilio account or need to enable a product. For Organization-level governance (SSO, SCIM, multi-team), see `twilio-organizations-setup`.
Handle rate limits, retries, and failures when building on Twilio at scale. Covers 429 exponential backoff with jitter, per-number throughput limits, StatusCallback resilience, thin-receiver pattern, and fallback chains. Use this skill whenever sending messages or making calls at volume, or when building production-grade Twilio integrations.
Implements agent-readiness on public sites and docs from Mintlify Agent Score, AFDocs, Is Agentic, Is It Agent Ready, or url-discovery-bench reports, or from server logs of agents 404ing on guessed URLs. Use when asked to "make our site agent-ready", "improve Agent Score", "fix llms.txt coverage", "agents keep 404ing on our docs", or when a pasted scorecard is the brief.
Two-pass audit and cleanup for a codebase that has started to congeal — spaghetti code, or "koshary code," where the layers have collapsed: business logic lives in the controller, the same validation sits in five files, and nobody wants to open the 800-line one. Pass 1 reports layer collapse, duplication that will drift, functions nobody reads, and dead code as a prioritized list and changes nothing; Pass 2 fixes in a safe order once the user approves. Security holes and vulnerable dependencies are covered too, as a later section rather than the headline. Use this whenever the user asks to audit, review, or clean up a codebase — and also when they say "this codebase is a mess," "spaghetti code," "technical debt," "this is unmaintainable," "duplicated logic," "dead code," "what's wrong with my code," or ask for a security review. Trigger it even when they never use the word "audit."
Generates paste-ready Power Apps Canvas App YAML. Invoke when the user wants to replicate a UI mockup, improve an existing Canvas app screen, or build a new screen from a text description. Also invoke when the user asks to “improve”, “redesign”, or “generate YAML” for a Canvas app screen.
This skill should be used when working with Convex actions, HTTP endpoints, validators, schemas, environment variables, scheduling, file storage, and TypeScript patterns. It provides comprehensive guidelines for function definitions, API design, database limits, and advanced Convex features.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
