Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Pywayne Cross Comm
pywayne.cross_comm.CrossCommService provides WebSocket-based real-time communication between Python and other languages, with built-in file transfer via Aliyun OSS.
Prerequisites
OSS Configuration (required for file/image/folder transfer): File transfers use Aliyun OSS. Set these environment variables: # .env file OSS_ENDPOINT=your-oss-endpoint OSS_BUCKET_NAME=your-bucket-name OSS_ACCESS_KEY_ID=your-access-key OSS_ACCESS_KEY_SECRET=your-access-secret For more OSS details, see pywayne-aliyun-oss skill.
Quick Start
import asyncio from pywayne.cross_comm import CrossCommService, CommMsgType # Server server = CrossCommService(role='server', ip='0.0.0.0', port=9898) await server.start_server() # Client client = CrossCommService(role='client', ip='localhost', port=9898, client_id='my_client') await client.login()
Initialize server
server = CrossCommService( role='server', ip='0.0.0.0', # Listen on all interfaces port=9898, heartbeat_interval=30, # Seconds between heartbeats heartbeat_timeout=60 # Seconds before marking offline )
Register message listeners
@server.message_listener(msg_type=CommMsgType.TEXT) async def handle_text(message): print(f"From {message.from_client_id}: {message.content}") @server.message_listener(msg_type=CommMsgType.FILE, download_directory="./downloads") async def handle_file(message): print(f"File downloaded: {message.content}")
Start server
await server.start_server() # Blocks until server stops
Get online clients
online_clients = server.get_online_clients() # Returns list of client IDs
Initialize client
client = CrossCommService( role='client', ip='localhost', # Server address port=9898, client_id='my_client', # Optional: auto-generated if omitted heartbeat_interval=30, heartbeat_timeout=60 )
Login and logout
success = await client.login() if success: print("Connected!") # ... communicate ... await client.logout()
Send messages
# Broadcast to all await client.send_message("Hello!", CommMsgType.TEXT) # Send to specific client await client.send_message("Private", CommMsgType.TEXT, to_client_id='target_id') # JSON message await client.send_message('{"key": "value"}', CommMsgType.JSON) # Dict message await client.send_message({"type": "data", "value": 123}, CommMsgType.DICT) # Bytes (auto base64 encoded) await client.send_message(b"binary", CommMsgType.BYTES) # File (auto uploads to OSS) await client.send_message("/path/to/file.txt", CommMsgType.FILE) # Image (auto uploads to OSS) await client.send_message("/path/to/image.jpg", CommMsgType.IMAGE) # Folder (auto uploads to OSS) await client.send_message("/path/to/folder", CommMsgType.FOLDER)
Get client list
# All clients (online + offline) all_clients = await client.list_clients(only_show_online=False) # Returns: {'clients': [...], 'total_count': N, 'only_show_online': False} # Online only online = await client.list_clients(only_show_online=True)
Message Types
CommMsgType enum (use these, not strings): TypeDescriptionCommMsgType.TEXTPlain textCommMsgType.JSONJSON stringCommMsgType.DICTPython dictCommMsgType.BYTESBinary dataCommMsgType.IMAGEImage fileCommMsgType.FILERegular fileCommMsgType.FOLDERFolder Internal types (auto-handled): HEARTBEAT, LOGIN, LOGOUT, LIST_CLIENTS, LIST_CLIENTS_RESPONSE, LOGIN_RESPONSE
Message Listener Decorator
# Listen to specific type @service.message_listener(msg_type=CommMsgType.TEXT) async def handler(message): pass # Listen from specific sender @service.message_listener(msg_type=CommMsgType.FILE, from_client_id='specific_client') async def handler(message): pass # Listen to all types @service.message_listener() async def handler(message): pass Note: Listeners automatically filter out messages sent by yourself.
File Download Control
File downloads are controlled via the listener's download_directory parameter: # Auto-download files to ./downloads @client.message_listener(msg_type=CommMsgType.FILE, download_directory="./downloads") async def handle_file(message): # message.content contains downloaded file path print(f"Downloaded: {message.content}") # No auto-download - saves bandwidth @client.message_listener(msg_type=CommMsgType.FILE, from_client_id='low_priority') async def handle_file(message): # message.content contains OSS key, not downloaded print(f"File available: {message.oss_key}") # Optionally: client.download_file_manually(message.oss_key, "./manual_downloads/")
Manual download
success = client.download_file_manually( oss_key="cross_comm/sender_id/123456_file.txt", save_directory="./downloads" )
Message Object
@dataclass class Message: msg_id: str # Unique message ID from_client_id: str # Sender ID to_client_id: str # 'all' or specific client ID msg_type: CommMsgType # Message type enum content: Any # Message content timestamp: float # Unix timestamp oss_key: Optional[str] # OSS key for file transfers def to_dict(self) -> Dict: # Convert to dict @classmethod def from_dict(cls, data) -> 'Message': # Create from dict
Client ID Generation
If client_id is not specified, it's auto-generated using MAC address + UUID: Format: {mac_address}_{uuid_suffix} Example: a1b2c3d4e5f6_abc12345
Command Line
# Run server python -m pywayne.cross_comm server # Run client python -m pywayne.cross_comm client
Important Notes
File transfer: Requires OSS environment variables; files auto-upload on send Async required: All operations are async; use asyncio.run() or await in async context Heartbeat: Auto-managed; adjust intervals for network conditions Message filtering: Use download_directory to control auto-downloads and save bandwidth State persistence: Server saves client status to cross_comm_clients.yaml Role-specific methods: Server has start_server(), get_online_clients(); client has login(), logout(), send_message(), list_clients()
