Please provide creative assistance by helping draft a collaborative structured and dynamic prompt template based on the following project concept described.

The template is an interactive user tool where the placeholders will be manually changed and dynamically rendered as UI input fields in a “mad-lib” style shell template generator that will be hydrated by the user’s intent.

The template doesn’t have to be restricted to any domain topic or approach. For example, we could have a prompt template that helps plan a user’s day or help create a plan to actually build software. But the core functionality is the form remains dynamic so when we do choose a topic, we can easily change the data to get new generative results.

Structural Requirements:

Please organize the output into these four logical zones, separated by clear line breaks:

1. Role & Core Objective: A bold statement defining the persona and primary task.
2. Contextual Instructions or Criteria: Bullet points detailing the logic for the generated output.
3. Dynamic Variables: A list of placeholders using the syntax defined below.
4. Constraints & Critical Rules: Essential formatting and behavioral guidelines.

Syntax for Dynamic Placeholders:

• For text inputs, please use: {{variable_slug}}
• For dropdown options, please use: {{variable_dropdown:option_1|option_2|option_3}}
• All slugs should be lower_case_with_underscores.
• Note: All brackets must be double {{curly_braces}} to ensure proper rendering.

Output Tone & Formatting Strictness:

• Provide the response strictly in a clean, technical, and structured format suitable for direct application parsing.
• Do not include conversational introductory or concluding remarks. Output only the final prompt template.

Intended Template Details:

• Core Tool Concept: {{tool_concept}}
• Target Framework or Language: {{target_framework}}
• Desired Variable Controls: {{desired_controls:text fields only|dropdown selectors only|mix of text and dropdowns}}

Please generate the prompt template based on these details.
