Tool Format

Nen returns standard JSON Schema from GET /tools. Convert to Anthropic’s format by mapping parameters → input_schema: 
tools = httpx.get(f"{NEN_URL}/tools").json()

anthropic_tools = [
    {"name": t["name"], "description": t["description"], "input_schema": t["parameters"]}
    for t in tools
]

​
