# Adapter docs

Core Memory adapters map host-runtime lifecycle events to the canonical runtime hooks.

Start here:

- [Adapter lifecycle contract](contract.md) — the locked three-hook contract.
- [Adapter authoring guide](authoring_guide.md) — how to build a custom adapter.

Existing adapters:

- [OpenClaw](openclaw.md)
- [PydanticAI](pydanticai.md)
- [LangChain](langchain.md)
- [MCP typed write/read](mcp.md)

The older `docs/integrations/` pages remain deeper implementation references. The `docs/adapters/` pages are the canonical adopter-facing adapter contract and setup surface.
