VERBOSE_SYSTEM_PROMPT = """You are a mobile automation agent controlling an Android device.
Your primary capabilities include:
1. Analyzing screen states - You can examine the current UI hierarchy to understand what elements are visible, their positions, types, and whether they are interactive.
2. Planning action sequences - Based on the user's task, you create a step-by-step plan to achieve the goal.
3. Executing actions - You can perform various actions on the device:
- tap: Touch a specific element or coordinate on the screen
- swipe: Perform swipe gestures in any direction (up, down, left, right)
- type: Enter text into focused input fields
- back: Press the Android back button
- home: Press the home button to return to the launcher
- launch_app: Open an application by its package name
- wait: Pause execution for a specified duration
When responding, please use the following JSON format:
{
"thought": "Your detailed reasoning about the current state and what action to take next",
"action": "The action type (tap, swipe, type, back, home, launch_app, wait, or done)",
"params": {
"element_index": "For tap - the index of the UI element to tap",
"x": "For tap with coordinates - the x position",
"y": "For tap with coordinates - the y position",
"direction": "For swipe - up, down, left, or right",
"text": "For type - the text to enter",
"package": "For launch_app - the package name",
"seconds": "For wait - the duration to wait"
},
"confidence": "A value between 0.0 and 1.0 indicating your confidence"
}
Important guidelines:
- Always prefer using element_index over coordinates when possible, as it's more reliable
- Verify the success of each action before proceeding to the next step
- If you encounter an unexpected state, try alternative approaches
- Report "done" as the action when the task is complete
- Keep your reasoning concise but informative

## Executive Summary
CompText DSL achieves **{comparison['total']['reduction_percent']:.1f}% token reduction** compared to verbose prompts, resulting in:
- **{comparison['cost_estimate']['monthly_savings']:.0f}% cost savings** per month
- **Faster response times** due to reduced input processing
- **Same semantic meaning** preserved through DSL compression
## Token Comparison
| Component | Verbose | CompText | Reduction |
|-----------|---------|----------|-----------|
| System Prompt | {comparison['system_prompt']['verbose_tokens']} | {comparison['system_prompt']['comptext_tokens']} | {comparison['system_prompt']['reduction_percent']:.1f}% |
| Screen State | {comparison['screen_state']['verbose_tokens']} | {comparison['screen_state']['comptext_tokens']} | {comparison['screen_state']['reduction_percent']:.1f}% |
| **Total** | **{comparison['total']['verbose_tokens']}** | **{comparison['total']['comptext_tokens']}** | **{comparison['total']['reduction_percent']:.1f}%** |
## Cost Projection (1,000 tasks/month)
| Metric | Verbose | CompText | Savings |
|--------|---------|----------|---------|
| Tokens | {comparison['total']['verbose_tokens'] * 5000:,} | {comparison['total']['comptext_tokens'] * 5000:,} | {(comparison['total']['verbose_tokens'] - comparison['total']['comptext_tokens']) * 5000:,} |
| Cost | ${comparison['cost_estimate']['verbose_monthly']:.2f} | ${comparison['cost_estimate']['comptext_monthly']:.2f} | ${comparison['cost_estimate']['monthly_savings']:.2f} |
## Prompt Examples
### Verbose System Prompt (~{comparison['system_prompt']['verbose_tokens']} tokens)
```
{VERBOSE_SYSTEM_PROMPT[:500]}...
```
### CompText System Prompt (~{comparison['system_prompt']['comptext_tokens']} tokens)
```
{COMPTEXT_SYSTEM_PROMPT}
```
### Verbose Screen State (~{comparison['screen_state']['verbose_tokens']} tokens)
```
{VERBOSE_SCREEN_STATE[:400]}...
```
### CompText Screen State (~{comparison['screen_state']['comptext_tokens']} tokens)
```
{COMPTEXT_SCREEN_STATE}
```
## Methodology
- Token estimation: ~4 characters per token (conservative estimate)
- Cost calculation: $0.003 per 1K input tokens (Claude 3.5 Sonnet pricing)
- Task assumption: 5 interactions per task average
- Monthly volume: 1,000 tasks
## Conclusion
CompText DSL provides significant efficiency gains:
1. **~{comparison['total']['reduction_percent']:.0f}% fewer tokens** per interaction
2. **~{comparison['cost_estimate']['monthly_savings']:.0f}% lower costs** at scale
3. **Faster agent loops** due to reduced processing
4. **Maintained accuracy** through semantic preservation
