================================================================================
KEY FEATURES
================================================================================

ZERO-CONTEXT EXECUTION
- Scripts work from any directory (scripts/, .claude/, project root)
- Automatic project root detection by searching for .git, pyproject.toml, .moai
- sys.path automatically setup for adb_auto_player imports

UNIFIED CLI INTERFACE
- All 29 scripts will have identical --device/-d, --toon, --verbose/-v options
- No inconsistent CLI flags across scripts
- User-friendly help text for all options

CONSISTENT ERROR HANDLING
- Base ADBError class with specific subclasses
- Proper exit codes for all error scenarios
- Meaningful error messages for debugging

RICH OUTPUT FORMATTING
- Color-coded console output (green/red/yellow/blue)
- Unicode symbols for visual feedback (✓ ✗ ⚠ ℹ)
- Rich tables for structured output
- YAML/TOON format for script integration

DEVICE DISCOVERY & VERIFICATION
- Auto-select first device or use explicit device_id
- Verify device is online with timeout
- List all connected devices
- Parse device output (pm list packages)

ENGLISH-ONLY CODE
- All functions, docstrings, comments in English
- Follows Python best practices
- Full type hints on all functions
- IndieDevDan 9-section docstring format

================================================================================
CODE QUALITY METRICS

USAGE EXAMPLE: MINIMAL SCRIPT
================================================================================

#!/usr/bin/env python3
import click
from common import (
    setup_adbautoplayer_path,
    device_option,
    get_default_device,
    print_success,
    ADBError,
)

setup_adbautoplayer_path()

@click.command()
@device_option
def main(device):
    try:
        device = get_default_device(device)
        print_success(f"Using device: {device}")

================================================================================
INTEGRATION CHECKLIST (Phase 6.1)
================================================================================

[ ] Use path_utils.setup_adbautoplayer_path() at script start
[ ] Use adb_utils functions for device operations
[ ] Add @device_option, @toon_output_option, @verbose_option decorators
[ ] Use cli_utils print_* functions for output
[ ] Use error_handlers exceptions for error handling
[ ] Replace all duplicate device code with adb_utils calls
[ ] Replace all custom CLI option parsing with decorators
[ ] Replace all custom output formatting with cli_utils functions
[ ] Replace all custom error handling with error_handlers

TARGET: 70% code duplication reduction across 29 scripts
