 ### Input Types
 
 - `string`: Default type. The parameter value is used as-is in template substitution
+- `number`: Numeric values. Desktop UI provides number input validation
+- `boolean`: True/false values. Desktop UI shows dropdown with "True"/"False" options
+- `date`: Date values. Currently renders as text input
 - `file`: The parameter value should be a file path. goose reads the file contents and substitutes the actual content (not the path) into the template
-
-When using `input_type: file`, this is useful for including file contents directly in your prompts or instructions.
+- `select`: Dropdown selection with predefined options. Requires `options` field
 
 **Example:**
 ```yaml
 parameters:
+  - key: max_files
+    input_type: number
+    requirement: optional
+    default: 10
+    description: "Maximum files to process"
+  
+  - key: output_format
+    input_type: select
+    requirement: required
+    description: "Choose output format"
+    options:
+      - json
+      - markdown
+      - csv
+  
+  - key: enable_debug
+    input_type: boolean
+    requirement: optional
+    default: false
+    description: "Enable debug mode"
+  
   - key: source_code
     input_type: file
     requirement: required
     description: "Path to the source code file to analyze"
 
-prompt: "Please review this code:\n\n{{ source_code }}"
+prompt: "Process {{ max_files }} files in {{ output_format }} format. Debug: {{ enable_debug }}. Code:\n\n{{ source_code }}"
 ```
 
-When you run this recipe with `source_code: /path/to/app.py`, goose will read the contents of `app.py` and substitute the actual code into the `{{ source_code }}` placeholder.
-
 :::important
 - Optional parameters MUST have a default value specified
 - Required parameters cannot have default values
 - File parameters cannot have default values regardless of requirement type to prevent unintended importing of sensitive files
+- Select parameters MUST have an `options` field with available choices
 - Parameter keys must match any template variables used in instructions, prompt, or activities
