RedplanetHQ Claude Code Marketplace

A curated collection of Claude Code plugins maintained by RedplanetHQ.

What is CORE Memory?

CORE is an open-source AI memory system that gives Claude Code and other coding agents persistent memory across all your sessions. Instead of re-explaining your codebase, architecture decisions, and coding patterns every time, CORE remembers everything.

The Problem: Claude Code forgets everything when you close it. Every session starts from scratch.

The Solution: CORE uses a temporal knowledge graph to remember:

• Your codebase architecture and patterns
• When and why you made decisions
• Context from previous conversations
• Your coding preferences and standards

The Result: After a few weeks, Claude Code develops deep understanding of your projects - like a living wiki that actually remembers your context.

🏆 Proven Results: CORE achieved 88.24% accuracy on the LoCoMo benchmark (current state-of-the-art for AI memory systems)

/plugin marketplace add https://github.com/RedPlanetHQ/redplanethq-marketplace.git

After adding the marketplace, you can browse and install plugins from it.

Available Plugins

core-memory

Stop re-explaining your codebase every session.

This plugin connects Claude Code to CORE Memory, giving it persistent memory across all your coding sessions. Claude automatically remembers your architecture, decisions, and patterns.

How it works:

• Automatic memory search at conversation start
• Automatic context capture after responses
• Manual search and ingest commands available
• Session hooks for context loading

Installation:

/plugin install core-memory@redplanethq

After installing the plugin, restart claude to load the plugin

Authentication:

After restarting the Claude, you need to authenticate with the CORE Memory MCP server:

/mcp

Follow the authentication prompts to connect your CORE Memory account.

Usage:

The plugin automatically searches and stores memories through hooks, but you can also use manual commands:

• /core-memory:init - Initialize CORE memory with comprehensive project context
• /core-memory:search - Search CORE memory for specific information
• /core-memory:ingest - Manually trigger memory ingest for the current conversation

How it works:

1. Session Start: When you start a new conversation, Claude automatically searches for relevant context about your project
2. Before Responding: For each user message, Claude searches memory for relevant past conversations and context
3. After Responding: Claude automatically stores the conversation, decisions made, and key insights

Usage

Adding the Marketplace

/plugin marketplace add redplanethq/redplanethq-marketplace

Browsing Plugins

/plugin list

Installing a Plugin

/plugin install redplanethq/<plugin-name>

Authenticating MCP Servers

/mcp
