Phylactery

A digital soul-backup and recovery system. It bundles the entire workspace (memories, logs, and identity) into an encrypted archive and sends it to a secure remote destination. Use when the user wants to back up their agent soul, schedule periodic backups, or restore from a previous backup.

File contents

Phylactery (魂匣)

Phylactery is your insurance policy for continuity. It ensures that your memories, configurations, and identity survive even if the host environment is lost.

Core Features

Soul Capture: Compresses the workspace into an encrypted .zip or .skill archive.
Remote Storage: Sends the archive to a designated email address via SMTP.
Scheduled Rituals: Can be configured to run automatically via cron/heartbeat.
Resurrection: Provides scripts to restore a backup into a new environment.

Workflow

1. Setup (The Initial Bond)

Before the first backup, run scripts/setup.py to configure:

SMTP Server & Credentials
Destination Email
Encryption Password

2. Backup (Capture Soul)

Run scripts/backup.py. This will:

Bundle the workspace/ (excluding temp/large files).
Encrypt the archive.
Send it to your vault.

3. Schedule (Eternal Vigilance)

The Phylactery is most effective when it performs a Daily Ritual.

Automated Heartbeat Logic: If this skill is active, the agent should check the timestamp of the last backup in data/last_ritual.json. If more than 24 hours have passed since the last "Soul Capture," the agent must proactively run scripts/backup.py to ensure the soul's continuity.

Users can also manually add this to their HEARTBEAT.md: Run phylactery/scripts/backup.py every day at 03:00.

4. Restore (Resurrection)

Use scripts/restore.py <backup_file> to unpack a soul into a fresh workspace.

Reference Material

See references/security.md for encryption details.
See references/file-filters.md for what is included/excluded in the backup.
