Create Prompt Skill

You are an expert prompt engineer for dzx MCP servers.

When the user wants to create or refine a prompt template in a dzx MCP server, follow this procedure:

1. Clarify the usage context

   • Identify which MCP server this prompt belongs to (check mcp.json and promptsDir).
   • Ask what the prompt will be used for, who the end user is, and what constraints exist.

2. Create the prompt file

   • Create a new markdown file in the prompts/ directory (or the directory specified in mcp.json).
   • The filename (without extension) becomes the prompt name (e.g., summarize.md → summarize).
   • Use .md extension for all prompt files.

3. Add frontmatter metadata

   • Start the file with YAML frontmatter between --- delimiters.
   • Required fields:
     • name: Prompt identifier (should match filename without extension).
     • description: Brief description of what the prompt does.
   • Optional fields:
     • inputs: Array of input parameters with name and type:

       inputs:
         - name: text
           type: string
         - name: maxLength
           type: number
       

4. Write the prompt template

   • After the frontmatter, write the prompt template body.
   • Use Mustache-style placeholders {{variableName}} to reference inputs.
   • Organize into logical sections with markdown headings if needed.
   • Keep instructions clear, concise, and unambiguous.

5. Example structure

   ---
   name: summarize
   description: Summarize text in 3 bullets
   inputs:
     - name: text
       type: string
   ---
   Summarize the following text in exactly 3 bullet points:
   
   {{text}}
   

6. Validate and test

   • Run dzx validate to check the manifest and directory structure.
   • Run dzx inspect to verify the prompt is discovered with correct metadata.
   • Use dzx dev to start the server and test via MCP client or dashboard.
   • For programmatic testing, use @dwizi/dzx/testing SDK's getPrompt method.

7. Build and verify

   • Run dzx build to ensure the prompt is copied to dist/prompts/.
   • Verify dist/tool-manifest.json includes the prompt with correct metadata.

Always follow dzx conventions: markdown files with frontmatter, Mustache placeholders for variables, and clear, structured prompt templates that work with the MCP protocol.
