Smart Memory
Enhanced memory management for OpenClaw. Zero external dependencies. Inspired by Claude Code's memdir architecture.
Requirements
- Runtime: Python 3.10+ (standard library only), Bash 4.0+ (health/extract scripts only)
- OS: Linux, macOS
- Environment variables (all optional, with defaults):
OPENCLAW_WORKSPACE — Workspace root (default: ~/.openclaw/workspace)
OPENCLAW_SESSION_ID — Session identifier for temp cache (default: default)
Security
Sensitive Data Protection
All write commands (session_state.py, session_cache.py) automatically reject inputs matching:
- API keys/tokens (OpenAI
sk-*, GitHub ghp_*, ClawHub clh_*)
- Passwords (
password=, passwd:, etc.)
- Private keys (
-----BEGIN PRIVATE KEY-----)
This is a hard block at the script level — the agent cannot bypass it. The regex patterns are conservative (high precision, may miss exotic formats); the agent should additionally avoid extracting any credential-like text even if not matched.
Input Sanitization
- Control characters stripped from all inputs
- Session ID sanitized to alphanumeric/hyphen/underscore only (prevents path traversal)
- Python-based scripts eliminate shell injection risks
Data Isolation
- All data stays local — no network calls, no cloud uploads
- Session cache uses
/tmp/ with sanitized session ID filenames
- No external dependencies or third-party packages

WAL Protocol (Write-Ahead Log)
Critical rule: Write BEFORE responding.
When the user provides information that should be remembered:
- Write to SESSION-STATE.md (via
session_state.py)
- Then respond to the user
This prevents context loss if compaction, crash, or restart happens between response and write.
| User Action |
WAL Write |
| States a preference |
session_state.py context "pref" "value" |
| Makes a decision |
session_state.py decide "chose X" |
| Gives a deadline |
session_state.py context "deadline" "date" |
| Corrects agent |
session_state.py decide "correction: X not Y" |
| Assigns task |
session_state.py task "description" |
| Mentions blocker |
session_state.py blocker "description" |
Memory Types
All entries tagged with a type prefix:
[PREF] — User preferences, habits, style
[PROJ] — Project context, active work, goals
[TECH] — Technical details, configs, system knowledge
[LESSON] — Lessons learned, errors, corrections
[PEOPLE] — People, relationships, social context
[TEMP] — Session-scoped, auto-expires
Core Workflows
Session Start
- Read
SESSION-STATE.md for current task/context
- Run
memory_search for relevant prior context
- Check
memory/YYYY-MM-DD.md for today's activity
During Conversation (WAL)
- User provides actionable info → write to SESSION-STATE.md FIRST
- Important facts → append to
memory/YYYY-MM-DD.md with type tag
- Use
session_cache.py for transient session data
Session End
- Update
SESSION-STATE.md with final state
- Promote durable items from daily notes to
MEMORY.md
- Run
memory_health.sh periodically to check hygiene
Periodic Maintenance
- Run
memory_decay.py when MEMORY.md > 200 lines or 50+ daily files
- Run
classify_memory.py to tag orphaned entries
- Archive daily files older than 90 days
Agent Behavior
Auto-Extract When
- User shares preference, opinion, or personal fact
- Project decision is made or changed
- Error encountered and resolved (→ LESSON)
- New people, tools, or workflows mentioned
Extraction Modes
- Keyword mode (default):
extract_memories.sh --auto "text" — zero token cost, pure Python
- LLM mode (opt-in): Use
references/extraction_prompt.md template — costs tokens, better quality
- Use keyword mode for most conversations; LLM mode only for long/complex sessions (20+ turns)
Do NOT Extract
- Passwords, tokens, API keys, credentials (scripts hard-block these)
- Private conversations about third parties not relevant to work
- Speculation or uncertain information ("user might prefer X")
- Transient state ("user is currently looking at page X")
- Information the user explicitly said not to remember
Auto-Decay When
- MEMORY.md exceeds 200 lines
- memory/*.md totals > 50 files
- On heartbeat if configured
