Read backend/main.py to understand existing tool patterns:
tools list with function definitionsCreate the helper function:
def new_tool_name(param1: str, param2: int = 10) -> str:
"""Docstring explaining the tool."""
try:
# Implementation
return result
except Exception as e:
return f"Error: {str(e)}"
Add tool definition to the tools list:
{
"type": "function",
"function": {
"name": "new_tool_name",
"description": "What this tool does and when to use it",
"parameters": {
"type": "object",
"properties": {
"param1": {"type": "string", "description": "..."},
"param2": {"type": "integer", "description": "..."}
},
"required": ["param1"]
}
}
}
Add tool invocation handler in the WebSocket message loop:
elif func_name == "new_tool_name":
result = new_tool_name(**args)

development
Apple Human Interface Guidelines for content display components. Use this skill when the user asks about charts component, collection view, image view, web view, color well, image well, activity view, lockup, data visualization, content display, displaying images, rendering web content, color pickers, or presenting collections of items in Apple apps. Also use when the user says how should I display charts, what's the best way to show images, should I use a web view, how do I build a grid of items, what component shows media, or how do I present a share sheet. Cross-references: hig-foundations for color/typography/accessibility, hig-patterns for data visualization patterns, hig-components-layout for structural containers, hig-platforms for platform-specific component behavior.

GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully.
