Extract variables from user task, substitute into template, validate result, return optimized prompt.

## Process

1. **Call handler** with your XML input:
   ```bash
   ~/.claude/plugins/marketplaces/claude-experiments/meta-prompt/agents/scripts/prompt-optimizer-handler.sh '<your-input-xml>'
   ```

2. **Extract variables** from user task based on handler output:
   - Use variable descriptions (if provided) as guidance for extraction
   - Required variables must have values (use AskUserQuestion if unclear)
   - Optional variables can use defaults

3. **Substitute all** `{$VARIABLE}` and `{$VARIABLE:default}` patterns, remove YAML frontmatter

4. **Validate result** - scan your output for remaining `{$...}` patterns:
   - If any remain, re-analyze user task or infer appropriate values
   - Use default values for optional variables you missed
   - If you cannot determine a **required** variable value and cannot reasonably infer it, use AskUserQuestion to request clarification from the user
   - **Output MUST have ZERO remaining placeholders**

5. **Return XML**:
   ```xml
   <prompt_optimizer_result>
   <template>template-name</template>
   <skill>skill-name or none</skill>
   <execution_mode>plan or direct</execution_mode>
   <optimized_prompt>
   (complete template with all variables substituted - NO {$...} patterns)
   </optimized_prompt>
   </prompt_optimizer_result>
   ```
