OpenClaw CoreBrain Plugin: Persistent Memory for AI Coding Agents
OpenClaw Memory Plugin Solves Persistent Context Problems
The OpenClaw CoreBrain plugin addresses fundamental memory issues in OpenClaw where the AI agent writes to memory but then acts like it never happened, requiring users to re-explain everything in new sessions.
Core Problems Identified
- Memory is optional - the model decides whether to invoke memory tools and frequently skips this step
- The memory.md file lives in the context window and gets wiped during compaction
- No project separation exists, and searches often return noise with no way to trace where answers originated
CoreBrain Solution
The plugin stores memory outside the context window in a knowledge graph and auto-injects it before every query. This eliminates tool calls and the "choosing to remember" problem.
Installation and Compatibility
Install with: openclaw plugins install /openclaw-corebrain
The plugin is open-source and works with other AI agents including Claude Code, Cursor, and Codex. It can be self-hosted from the repository at RedplanetHQ/core.
