Raven Memory

Raven gives your OpenClaw agent persistent causal memory that survives across sessions, days, and weeks.

What it does

• Records every significant event as a node in a causal chain
• Loads relevant history at session start via semantic search
• Supports rollback, branching, and parallel task tracking
• Stores everything locally in ~/.raven/raven.db
• Encrypted at rest with SQLCipher (optional)

Tools exposed

• raven_start_session — load context at conversation start
• raven_record_event — write an event to the chain
• raven_end_session — close session with notes
• raven_search — semantic search over full history
• raven_rollback — undo N steps
• raven_get_status — health check

Setup

Install from PyPI:

pip install raven-memory

With semantic search (recommended):

pip install "raven-memory[vec]"

Then install this skill:

clawhub install raven-memory

Add to your OpenClaw system prompt:

At the start of every conversation, call raven_start_session with
the user's first message as search_query. Load the returned
summary/nodes into your context before responding. Record events with raven_record_event. End sessions with raven_end_session.
