Advanced Features

Take your prompts to the next level with variables, prompt references, markdown formatting, and MCP integration.

Variables​

Variables make prompts flexible by creating placeholders for dynamic content that changes each time you use the prompt.

Basic Syntax​

Wrap variable names in double curly braces:

{{variable_name}}

Variable Examples​

Content Creation

Write a {{content_type}} about {{topic}} for {{audience}}.

The content should be {{tone}} and approximately {{word_count}} words long.

Key points to cover:
- {{point_1}}
- {{point_2}}
- {{point_3}}

Code Review

Review this {{language}} code for:
- Performance issues
- Security vulnerabilities
- Best practices
- Code style

Code:
{{code_snippet}}

Email Template

Write a professional {{email_type}} to {{recipient}} regarding {{subject}}.

Context: {{background_info}}
Objective: {{desired_outcome}}
Tone: {{tone}}

Variable Naming Best Practices​

Use descriptive, lowercase names with underscores:

✅ {{target_audience}}
✅ {{word_count}}
✅ {{email_type}}

❌ {{var1}}
❌ {{TA}}
❌ {{Type-Of-Content}}

Make names self-explanatory:

✅ {{customer_support_issue}}
❌ {{issue}}

✅ {{blog_post_title}}
❌ {{title}}

Group related variables:

{{seo_title}}
{{seo_description}}
{{seo_keywords}}

Avoid special characters except underscores:

✅ {{primary_cta}}
❌ {{primary-cta}}
❌ {{primary.cta}}
❌ {{primary cta}}

Variable Limitations​

No nested variables: Variables cannot contain other variables

❌ {{var_{{other_var}}}}

No default values: Variables don't currently support default values (feature planned)

Document expected formats in your prompt:

Write about {{topic}}.

Format: {{output_format}}
(options: blog-post, social-media, email, documentation)

Prompt References​

Build modular, composable prompts by referencing existing ones using the @ syntax.

How to Reference Prompts​

  1. In the prompt editor, type @
  2. A list of available prompts appears
  3. Select a prompt to insert its reference
  4. The syntax is: @prompt-slug

Example Use Case​

Base Instructions Prompt (slug: base-instructions)

You are a professional technical writer.
Follow these guidelines:
- Use clear, concise language
- Structure content with headings
- Include code examples where relevant
- Write for a developer audience

Blog Post Prompt (references base instructions)

@base-instructions

Write a technical blog post about {{topic}}.

Target audience: {{audience}}
Length: {{word_count}} words
Include: {{key_points}}

When you use the Blog Post prompt, it automatically includes the content from base-instructions.

Benefits of Prompt References​

DRY Principle (Don't Repeat Yourself) Write common instructions once and reuse everywhere. Update the base prompt and all references update automatically.

Layered Complexity Combine simple prompts into sophisticated workflows:

@company-tone-guidelines

@blog-structure

Write about {{topic}} following the above guidelines.

Team Standards Share base prompts to ensure everyone follows the same guidelines:

@coding-standards

@security-checklist

Review the code in {{file_path}}.

Best Practices for References​

Create Base Prompts for Common Patterns

  • Company voice and tone
  • Formatting standards
  • Security guidelines
  • Code style rules

Keep Base Prompts Focused Each base prompt should cover one aspect. Combine multiple references rather than creating one massive base prompt.

Document Dependencies In the prompt description, note which prompts it references. This helps prevent broken references.

Test Before Deleting Before deleting a prompt, search your library for @prompt-slug to find all references.

Markdown Formatting​

The prompt editor supports markdown for rich text formatting.

Supported Markdown Syntax​

Bold text

**bold text** or __bold text__

Italic text

*italic text* or _italic text_

Code snippets

Inline `code` or blocks:

code block

Headings

# Heading 1
## Heading 2
### Heading 3

Lists

- Bullet point
- Another point

1. Numbered item
2. Another item

Links

[Link text](https://example.com)

Blockquotes

> This is a quote

Formatting Best Practices​

Use structure to improve clarity:

Write a product description with:

## Introduction
Brief overview highlighting the main benefit

## Key Features
- Feature 1: {{feature_1}}
- Feature 2: {{feature_2}}
- Feature 3: {{feature_3}}

## Technical Specifications
{{specs}}

## Call to Action
End with a compelling reason to {{desired_action}}

Emphasize important instructions:

Write a blog post about {{topic}}.

**IMPORTANT**: Use a {{tone}} tone and avoid technical jargon.

*Note*: Include at least 3 real-world examples.

Create clear sections:

# Task
Write a product comparison

## Requirements
- Compare {{product_1}} vs {{product_2}}
- Focus on {{comparison_criteria}}
- Length: {{word_count}} words

## Format
Use a table with these columns:
- Feature
- {{product_1}}
- {{product_2}}
- Winner

MCP Integration​

Make your prompts accessible directly from AI tools through the Model Context Protocol.

What is MCP?​

MCP (Model Context Protocol) is a standard that allows AI applications to access external resources. VibeXP's MCP server lets you use your prompts in:

  • Claude Code CLI
  • Cursor IDE
  • VS Code with Claude extension
  • Other MCP-compatible tools

Enabling MCP Access​

  1. Edit your prompt
  2. In the Settings panel, check Available in MCP
  3. Save the prompt (Published status recommended)

Using MCP-Enabled Prompts​

Once enabled, your prompts become available in connected applications. The exact usage depends on the tool:

Claude Code

# List available prompts
claude-code mcp prompts list

# Use a prompt
claude-code use prompt blog-post-template

Cursor / VS Code Prompts appear in the MCP resources panel and can be inserted directly into your editor.

MCP Configuration​

To connect VibeXP's MCP server to your tools, see the MCP Server Integration guide for complete setup instructions.

MCP API Capabilities​

Connected applications can:

  • List all your published MCP-enabled prompts
  • Fetch full prompt content
  • Resolve variable placeholders
  • Execute prompts with parameters
  • Access prompt metadata

Best Practices for MCP Prompts​

Publish MCP-enabled prompts While drafts can be MCP-enabled, published prompts are more stable for tool integration.

Use clear, unique names Tool users will see prompt names in selection lists. Make them descriptive and distinguishable.

Document variables in the description Help tool users understand what variables the prompt expects.

Test in your target tools Verify the prompt works as expected in the applications where it will be used.

Combining Features​

The most powerful prompts combine multiple features:

@company-voice

@content-structure

Write a {{content_type}} about {{topic}}.

**Target Audience:** {{audience}}
**Word Count:** {{word_count}}
**Tone:** {{tone}}

## Required Sections
- Introduction
- {{section_1}}
- {{section_2}}
- {{section_3}}
- Conclusion

*Include real-world examples for each section.*

This prompt:

  • References two base prompts for consistency
  • Uses variables for flexibility
  • Applies markdown for structure
  • Can be MCP-enabled for tool integration
