Mema Brain

核心功能分两部分：SQLite文档元数据索引，可记录文件路径、标题、标签，支持索引添加与标签/时效性筛选搜索；Redis短期内存，存储临时键值对，默认6小时过期，支持设置与获取。适用于整理工作区知识路径、跨会话管理临时状态，通过Python脚本命令行操作，数据本地存储保障隐私。

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 <path> [--tag <tag>]

Searching Index

List indexed paths filtered by tag or recency.

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

Mental State (Redis)

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

Set: python3 $WORKSPACE/skills/mema/scripts/mema.py mental set <key> <value> [--ttl N]
Get: python3 $WORKSPACE/skills/mema/scripts/mema.py mental get <key>

Setup

Copy env.example.txt to .env.
Configure REDIS_HOST and REDIS_PORT (defaults: localhost:6379).
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.
