Mema Brain (Centralized Memory)

Standardized memory system providing a Metadata Index (SQLite) and Short-Term Context (Redis).

Core Components

1. Document Index (SQLite)

Primary Path: ~/.openclaw/memory/main.sqlite

Capability: Stores file paths, titles, and tags.

Note: This is a Metadata Index only. It does not ingest or provide full-text search of file contents.

2. Short-Term Memory (Redis)

Key Prefix: mema:mental:*

Purpose: Ephemeral state management and cross-session context passing.

TTL: Default 6 hours (21600 seconds).

Core Workflows

Indexing Knowledge

Record a file's location and tags in the local database.

Usage: python3 $WORKSPACE/skills/mema/scripts/mema.py index [--tag ]

Searching Index

List indexed paths filtered by tag or recency.

Usage: python3 $WORKSPACE/skills/mema/scripts/mema.py list [--tag ]

Mental State (Redis)

Manage key-value pairs in the mema:mental namespace.

Set: python3 $WORKSPACE/skills/mema/scripts/mema.py mental set [--ttl N]

Get: python3 $WORKSPACE/skills/mema/scripts/mema.py mental get

Setup

1. Copy env.example.txt to .env. 2. Configure REDIS_HOST and REDIS_PORT (defaults: localhost:6379). 3. Initialize the SQLite schema: python3 $WORKSPACE/skills/mema/scripts/mema.py init

Reliability & Security

Data Privacy: All data is stored locally.

Network Safety: Only point REDIS_HOST to trusted instances.

Path Isolation: Database operations are confined to the ~/.openclaw/memory directory.
