Custom Python Adapter - Charm Docs

Use the custom adapter when your agent is a plain Python function or class.

Manifest

runtime:
  adapter:
    type: "custom"
    entry_point: "src.main:agent"

Supported Shape

The entry point can be an object with an invoke method:

class Agent:
    def invoke(self, inputs: dict, **kwargs) -> dict:
        return {"output": "Hello"}

agent = Agent()

Or a callable function, depending on the template and runtime wrapper.

Input and Output

Inputs come from interface.input and are passed as a dictionary. Return a JSON-serializable dictionary so the Store can render the result.

Best For

Lightweight agents.
API wrappers.
Text transformation.
Existing Python code you want to publish quickly.
