ByteRover Memory Plugin for OpenClaw: Native Integration with Semantic Hierarchy

The ByteRover Memory Plugin is now available for OpenClaw, offering native integration for structured, long-term memory management through ClawHub. This plugin moves beyond vector databases to implement a semantic hierarchy approach.

Key Features

• Three-Layer Memory Architecture: Context Tree (structured knowledge base), Workspace Memory (core rules/preferences/guidelines), and Daily Memory (session notes)
• Git-like Stateful Memory: Organizes memory into a semantic hierarchy of human-readable, diffable, and git-friendly Markdown files
• Local-first but Fully Portable: Local-by-default, fully portable for multi-agent teams
• High Accuracy: Achieves 92.2% retrieval accuracy on both LoCoMo and LongMemEval benchmarks, maintaining 90% accuracy even with cheap & lightweight models

Technical Integration

The plugin builds on OpenClaw's recent changes. On March 21, 2026, OpenClaw merged PR #50848, which adds an optional prompt parameter to ContextEngine.assemble(), allowing retrieval-oriented engines to use the current user query when assembling context.

Setup Requirements

• OpenClaw v2026.3.22+ is required
• If upgrading from earlier versions: remove the plugins.allow field from your openclaw.json and restart the gateway

Installation

Complete automation loop installs via a single interactive script:

curl -fsSL https://byterover.dev/openclaw-setup.sh | sh

Or install the plugin only:

openclaw plugins install /byterover

The plugin is available on NPM at @byterover/byterover and has been submitted to ClawHub, where it's currently undergoing security review.
