BackendSlots

The BackendSlots dataclass holds the two backend references used by ChatObject at runtime for data I/O.

Description

BackendSlots is a simple dataclass that bundles an AbilityBackend and a MemoryBackend together so they can be passed as a single argument to ChatObject or AgentRuntime.

Fields

• ability (AbilityBackend): Backend responsible for loading tools, MCP clients, and presets
• memory (MemoryBackend): Backend responsible for loading and committing conversation memory

Usage

from amrita_core.base.backend import BackendSlots
from amrita_core.builtins.backends import LegacyBackend

bkd = LegacyBackend()
slot = BackendSlots(ability=bkd, memory=bkd)

# Pass to ChatObject
chat = ChatObject(
    train=train,
    user_input="Hello",
    session_id="my_session",
    backend=slot,
)

Default Behavior

When backend=None is passed to ChatObject or AgentRuntime, the default is:

bkd = LegacyBackend()
slot = BackendSlots(bkd, bkd)

This uses in-process global containers for both memory and ability storage.
