# Cremote MCP Tools - Performance & Best Practices

This document provides performance optimization guidelines and best practices for using the cremote MCP tools effectively in production environments.

## 🚀 Performance Optimization

### 1. Batch Operations for Maximum Efficiency

#### ✅ **10x Form Efficiency**
**Instead of this (10+ API calls):**
```yaml
web_interact_cremotemcp:
  action: "fill"
  selector: "#field1"
  value: "value1"

web_interact_cremotemcp:
  action: "fill"
  selector: "#field2"
  value: "value2"

# ... 8 more individual calls
```

**Use this (1-2 API calls):**
```yaml
web_form_fill_bulk_cremotemcp:
  form_selector: "#form"
  fields:
    field1: "value1"
    field2: "value2"
    field3: "value3"
    # ... all fields in one call
```

#### ✅ **Batch Data Extraction**
**Instead of this (multiple calls):**
```yaml
web_extract_cremotemcp:
  type: "element"
  selector: "h1"

web_extract_cremotemcp:
  type: "element"
  selector: ".price"

web_extract_cremotemcp:
  type: "element"
  selector: ".description"
```

**Use this (single call):**
```yaml
web_extract_multiple_cremotemcp:
  selectors:
    title: "h1"
    price: ".price"
    description: ".description"
```

### 2. Smart Element Checking

#### ✅ **Prevent Timing Issues**
**Always check before acting:**
```yaml
# 1. Check if element exists and is ready
web_element_check_cremotemcp:
  selector: "#submit-button"
  check_type: "all"

# 2. Only proceed if element is ready
web_interact_cremotemcp:
  action: "click"
  selector: "#submit-button"
```

#### ✅ **Form Intelligence**
**Analyze before filling:**
```yaml
# 1. Understand form structure first
web_form_analyze_cremotemcp:
  selector: "#registration-form"

# 2. Fill based on analysis results
web_form_fill_bulk_cremotemcp:
  form_selector: "#registration-form"
  fields:
    # Fields based on analysis
```

### 3. Efficient File Operations

#### ✅ **Bulk File Transfers**
**Instead of individual uploads:**
```yaml
file_operations_bulk_cremotemcp:
  operation: "upload"
  files:
    - local_path: "/file1.pdf"
      container_path: "/tmp/file1.pdf"
    - local_path: "/file2.pdf"
      container_path: "/tmp/file2.pdf"
    # Multiple files in one operation
```

#### ✅ **Automated Cleanup**
```yaml
file_management_cremotemcp:
  operation: "cleanup"
  pattern: "/tmp/cremote-*"
  max_age: "24"  # Clean files older than 24 hours
```

## 🎯 Best Practices for LLM Agents

### 1. **Error Prevention Strategies**

#### ✅ **Always Check Element State**
```yaml
# Check before every interaction
web_element_check_cremotemcp:
  selector: "#target-element"
  check_type: "exists"

# Only proceed if element exists
```

#### ✅ **Verify Page Loading State**
```yaml
# Check if page is fully loaded
web_content_check_cremotemcp:
  type: "scripts"

# Check if images are loaded
web_content_check_cremotemcp:
  type: "images"
```

#### ✅ **Monitor JavaScript Errors**
```yaml
# Check for console errors
console_logs_cremotemcp:
  clear: false

# Look for error patterns in logs
```

### 2. **Timeout Management**

#### ✅ **Appropriate Timeout Values**
- **Navigation**: 10-15 seconds for complex pages
- **Element interactions**: 5-10 seconds
- **Form operations**: 10-15 seconds for complex forms
- **File operations**: 30-60 seconds for large files

```yaml
web_navigate_cremotemcp:
  url: "https://complex-app.com"
  timeout: 15  # Longer for complex pages

web_form_fill_bulk_cremotemcp:
  form_selector: "#complex-form"
  fields: {...}
  timeout: 15  # Longer for complex forms
```

### 3. **Resource Management**

#### ✅ **Tab Management**
```yaml
# Open new tab for parallel operations
web_manage_tabs_cremotemcp:
  action: "open"

# Close tabs when done
web_manage_tabs_cremotemcp:
  action: "close"
  tab: "tab-id"
```

#### ✅ **Memory Management**
```yaml
# Monitor performance impact
web_performance_metrics_cremotemcp: {}

# Clean up files regularly
file_management_cremotemcp:
  operation: "cleanup"
  pattern: "/tmp/*"
  max_age: "1"
```

## 📊 Performance Monitoring

### 1. **Page Performance Tracking**

```yaml
# Get baseline performance
web_performance_metrics_cremotemcp: {}

# Perform operations...

# Check performance impact
web_performance_metrics_cremotemcp: {}
```

**Key Metrics to Monitor:**
- `load_time`: Page load duration
- `dom_content_loaded`: DOM ready time
- `resource_count`: Number of resources loaded
- `js_heap_size_used`: Memory usage

### 2. **Viewport Optimization**

```yaml
# Check viewport for responsive testing
web_viewport_info_cremotemcp: {}

# Adjust operations based on viewport size
```

## 🛠 Debugging Best Practices

### 1. **Enhanced Screenshots for Debugging**

#### ✅ **Element-Specific Screenshots**
```yaml
# Screenshot specific problematic elements
web_screenshot_element_cremotemcp:
  selector: "#problematic-element"
  output: "/tmp/debug-element.png"
```

#### ✅ **Enhanced Screenshots with Metadata**
```yaml
# Full context screenshots
web_screenshot_enhanced_cremotemcp:
  output: "/tmp/debug-full-context.png"
  full_page: true
```

### 2. **Console Debugging**

```yaml
# Check for JavaScript errors
console_logs_cremotemcp:
  clear: false

# Execute debug commands
console_command_cremotemcp:
  command: "console.log(document.readyState)"
```

### 3. **Page State Analysis**

```yaml
# Get comprehensive page information
web_page_info_cremotemcp: {}

# Check content loading state
web_content_check_cremotemcp:
  type: "scripts"
```

## 🎯 Production Deployment Guidelines

### 1. **Environment Configuration**

```bash
# Optimal environment variables
export CREMOTE_HOST=localhost
export CREMOTE_PORT=8989
export CREMOTE_TIMEOUT=30
```

### 2. **Resource Limits**

- **Concurrent Operations**: Limit to 3-5 parallel browser tabs
- **File Operations**: Monitor disk space for temporary files
- **Memory Usage**: Monitor JavaScript heap size

### 3. **Error Handling Patterns**

```yaml
# Always include error checking
web_element_check_cremotemcp:
  selector: "#target"
  check_type: "exists"

# Implement retry logic for critical operations
# (handled by LLM agent logic)
```

### 4. **Monitoring and Logging**

- Monitor `web_performance_metrics_cremotemcp` results
- Track `console_logs_cremotemcp` for errors
- Use enhanced screenshots for debugging
- Implement automated cleanup with `file_management_cremotemcp`

## 🚀 Advanced Optimization Techniques

### 1. **Parallel Operations**

Use multiple tabs for parallel data collection:
```yaml
# Open multiple tabs for parallel processing
web_manage_tabs_cremotemcp:
  action: "open"

# Process different pages simultaneously
```

### 2. **Intelligent Caching**

- Cache form analysis results for similar forms
- Reuse element attribute data when possible
- Store performance baselines for comparison

### 3. **Conditional Workflows**

Use element checking to create smart, adaptive workflows:
```yaml
# Adapt workflow based on page state
web_element_check_cremotemcp:
  selector: "#login-required"
  check_type: "exists"

# LLM decides next steps based on result
```
