  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 6 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by syncfusion on GitHub. Read the source before you install it.

Installation

Install the Syncfusion Maui Masked Entry AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/syncfusion/maui-ui-components-skills/tree/master/skills/syncfusion-maui-masked-entry
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/syncfusion/maui-ui-components-skills.git /tmp/maui-ui-components-skills
mkdir -p .claude/skills
cp -r /tmp/maui-ui-components-skills/skills/syncfusion-maui-masked-entry .claude/skills/syncfusion-maui-masked-entry
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Syncfusion Maui Masked Entry in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Syncfusion Maui Masked Entry on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Syncfusion Maui Masked Entry is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Implementing .NET MAUI Masked Entry

The Syncfusion .NET MAUI Masked Entry (SfMaskedEntry) is an advanced input control that restricts and formats user input using customizable mask patterns. It provides automatic validation, formatting, and visual feedback for structured data entry like phone numbers, dates, emails, product keys, and more.

When to Use This Skill

Use this skill when users need to:

  • Formatted Input Fields: Phone numbers, dates, times, SSN, credit cards, ZIP codes, product keys
  • Restricted Character Entry: Only accept specific characters (digits, letters, alphanumeric)
  • Pattern Validation: Validate input against fixed or variable-length patterns
  • Automatic Formatting: Apply separators, delimiters, and formatting as user types
  • Culture-Specific Input: Handle currency symbols, date/time separators, decimal formats
  • Password Fields with Masking: Show/hide characters with customizable delay
  • Email and URL Validation: Use RegEx patterns for complex validation
  • Data Entry Forms: Improve UX with guided input and instant feedback
  • Accessibility Requirements: Provide clear input expectations with prompts and validation

Component Overview

Key Capabilities:

  • Two mask types: Simple (fixed patterns) and RegEx (flexible patterns)
  • Customizable prompt characters showing expected input positions
  • Flexible value formatting (include/exclude prompts and literals)
  • Real-time validation with multiple validation modes
  • Rich event system for monitoring and controlling input
  • Extensive customization (colors, fonts, borders, clear button)
  • Culture support for international formats
  • Password masking with visibility control
  • Modern Liquid Glass effect integration
  • Full accessibility and automation support

Frequently asked questions

What does the Syncfusion Maui Masked Entry AI skill do?

Implements Syncfusion .NET MAUI Masked Entry (SfMaskedEntry) control for restricted, formatted text input with mask patterns. Use when working with masked input, text masks, formatted entry, phone number input, date input with format, or validation with masks. Covers Simple masks, RegEx masks, prompt characters, and automatic formatting with validation.

Why use Syncfusion Maui Masked Entry on TypingMind?

Because you install it once and use it with any model. Syncfusion Maui Masked Entry is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Syncfusion Maui Masked Entry in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/syncfusion/maui-ui-components-skills/tree/master/skills/syncfusion-maui-masked-entry. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Syncfusion Maui Masked Entry?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Syncfusion Maui Masked Entry?

As many as you like. As long as a model supports skills, you can use Syncfusion Maui Masked Entry with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Syncfusion Maui Masked Entry AI skill free?

It is published on GitHub by syncfusion. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
