"""OpenViking memory plugin — full bidirectional MemoryProvider interface.
|
|
|
|
OpenViking (Volcengine/ByteDance) organizes agent knowledge into a viking://
|
|
filesystem hierarchy with tiered context (L0 abstract / L1 overview / L2 full),
|
|
automatic memory extraction on session commit, and semantic search.
|
|
|
|
Config comes from env vars (OPENVIKING_ENDPOINT / _API_KEY / _ACCOUNT / _USER /
|
|
_AGENT, profile-scoped via .env) or a linked OpenViking CLI config (ovcli.conf).
|
|
The interactive setup wizard lives in ``_setup.py``.
