Memoria Memory System

Manages AI assistant long-term memory with layered storage for facts, events, skills, context, and fast indexing, including backup and integrity tools.

Memoria System

Overview

Memoria System is a comprehensive long-term memory management system designed for AI assistants. It implements a human-like cognitive memory architecture with distinct layers for different types of information.

Memory Architecture

The system organizes memory into five distinct types, mirroring human cognitive structures:

1. Semantic Memory (semantic/)

Stores factual knowledge, concepts, and general information.

• facts.md - Personal facts and key information
• concepts.md - Learned concepts and knowledge
• knowledge/ - Detailed knowledge entries

2. Episodic Memory (episodic/)

Records events, experiences, and conversations with timestamps.

• YYYY-MM-DD.md - Daily memory logs
• events/ - Specific event documentation

3. Procedural Memory (procedural/)

Contains skills, workflows, and learned procedures.

• skills.md - Acquired skills and capabilities
• workflows.md - Common procedures and workflows
• scripts/ - Automation and utility scripts

4. Working Memory (working/)

Holds current session context and active tasks.

• current.md - Active context and pending items
• session/ - Session-specific data

5. Index (index/)

Provides fast lookup and search capabilities.

• tags.json - Tag-based indexing
• timeline.json - Chronological event index
• search/ - Search indexes

Tools

memory-backup.sh

Creates incremental backups of the memory system.

Usage:

bash

./memory-backup.sh [options]

Options:

• --dry-run - Show what would be backed up without doing it
• --verbose - Show detailed output
• --path PATH - Override memory path
• --output PATH - Override backup destination

memory-migrate.sh

Initializes new memory structures or migrates existing ones.

Usage:

bash

./memory-migrate.sh {init|daily [DATE]|migrate [VERSION]}

Commands:

• init - Initialize memory structure
• daily [DATE] - Create daily memory file (default: today)
• migrate [VERSION] - Migrate from specified version

memory-rollback.sh

Restores memory from a previous backup.

Usage:

bash

./memory-rollback.sh {list|rollback BACKUP_NAME [--force]}

Commands:

• list - List available backups
• rollback BACKUP_NAME - Restore to specified backup

Options:

• --force - Skip confirmation prompt

memory-health-check.sh

Validates memory integrity and optionally repairs issues.

Usage:

bash

./memory-health-check.sh [options]

Options:

• --fix - Automatically fix detected issues
• --path PATH - Override memory path

Configuration

Edit config.json to customize behavior:

json

{
  "memory": {
    "base_path": "./memory",
    "structure": { ... }
  },
  "backup": {
    "enabled": true,
    "retention_days": 30,
    "schedule": "0 2 * * *"
  },
  "health_check": {
    "auto_fix": false,
    "check_interval_hours": 24
  }
}

Cron Setup

Add to crontab for automated maintenance:

bash

# Daily backup at 2 AM
0 2 * * * cd /path/to/memoria-system && ./memory-backup.sh

# Weekly health check on Sundays at 3 AM
0 3 * * 0 cd /path/to/memoria-system && ./memory-health-check.sh --fix

Installation

bash

openclaw skill install memoria-system

Requirements

• Bash 4.0+
• jq (for JSON processing)
• tar (for backup compression)
