Claude Memory Plugin

Institutional memory system for Claude Code. Captures and retrieves lessons learned, architectural decisions, and common issues.

Developed by the Transport Systems & Logistics Laboratory at Imperial College London.

Installation

/plugin marketplace add tsl-imperial/tsl-claude-plugins
/plugin install memory-system@tsl-claude-plugins

Then initialize the memory system in your project:

/memory-init

Components

Component	Description
Hook	Reminds to check memory before every task
/memory-init	Initializes _memory/ directory structure
/documentmemory	Creates new memory documents
memory-search agent	Searches memory for relevant solutions

How It Works

1. Hook fires on every message, reminding to check _memory/TOC.md
2. Search memory for existing solutions before investigating
3. Document new solutions with /documentmemory after solving issues

CLAUDE.md Integration

The /memory-init command automatically adds a Mandatory Memory Check Protocol section to your project's CLAUDE.md file. This ensures Claude Code always checks memory before investigating issues or implementing features.

The protocol is customizable - adjust the language to match your project's domain (web apps, mobile apps, libraries, etc.).

Multi-Directory Support

When working with multiple directories in a Claude Code session:

• Check for memory in added directories: External directories may have their own _memory/ systems
• Cross-reference: Solutions from one project may apply to another
• Respect boundaries: Each project's memory is scoped to that project
