Key Commands

Command	Description
`openclaw-mem search "query"`	Semantic search over memory
`openclaw-mem index --all`	Index all markdown files
`openclaw-mem index --changed`	Incremental index (changed files only)
`openclaw-mem observe "text" --tag learning`	Record a structured observation
`openclaw-mem auto-capture --since 6h`	Extract observations from session transcripts
`openclaw-mem auto-capture --since 6h --route-to-brain`	Auto-route observations to Brain files
`openclaw-mem brain-check`	Check Brain files for injection patterns
`openclaw-mem brain-check --fix`	Auto-fix injection patterns
`openclaw-mem archive --execute`	Archive old memory (3-Layer: Hot/Warm/Cold)

Brain Directories

Per-project persistent context stored in memory/projects/{name}.md:

# Create a project Brain
echo "# My Project Brain\n\n## Architecture\n- Stack: Python + FastAPI\n" > memory/projects/my-project.md

# Index it
openclaw-mem index memory/projects/my-project.md

# Search across all Brains
openclaw-mem search "project architecture"

# Verify integrity
openclaw-mem brain-check

Progressive Disclosure (2-Step Search)

Reduces token usage by returning summaries first, then full content on demand:

# Step 1: Get summaries (index view)
openclaw-mem search "deployment" --index
# Returns: chunk IDs + one-line summaries

# Step 2: Get full content for a specific chunk
openclaw-mem search --detail "chunk:0:abc123"
# Returns: full chunk text

Observation Tags

Tag observations for structured knowledge capture:

openclaw-mem observe "Redis cache TTL should be 1h" --tag decision
openclaw-mem observe "Always test with --dry-run first" --tag learning
openclaw-mem observe "Forgot to check edge case" --tag mistake
openclaw-mem observe "Service mesh pattern works well" --tag architecture
openclaw-mem observe "User prefers dark mode" --tag preference
openclaw-mem observe "Next: add WebSocket support" --tag next

Security

Injection Defense: Brain files are scanned for prompt injection patterns
Sanitizer: All indexed content passes through the injection sanitizer
Local-first: No data leaves your machine — embeddings run locally
