OpenClaw Memory Curator

A session-first memory system for OpenClaw.

It exists for one reason: important knowledge must survive session compaction without bloating the context window.


TL;DR (for humans)

  • Session memory = temporary (RAM)
  • Disk = source of truth
  • Decisions & preferences → MEMORY.md
  • Daily work → memory/YYYY-MM-DD.md
  • This skill saves durable knowledge before compaction
  • Retrieval always happens via memory_searchmemory_get

If something matters later, write it to disk.


⚠️ CRITICAL REQUIREMENT

Session memory indexing must be enabled.

Enable Session Memory

CLI bash clawdbot config set agents.defaults.memorySearch.experimental.sessionMemory true

JSON json { "agents": { "defaults": { "memorySearch": { "experimental": { "sessionMemory": true }, "sources": ["memory", "sessions"] } } } }


Mental Model (read this once)

OpenClaw memory has three layers. Confusion usually comes from mixing them up.

1. Session Memory (RAM)

  • Lives in the current conversation
  • Automatically compacted
  • Indexed for retrieval
  • Never reliable long-term

👉 Treat as short-term thinking space.


2. Daily Logs (memory/YYYY-MM-DD.md)

  • Append-only
  • What happened today
  • Commands, edits, short-lived issues

👉 Treat as a work log, not a knowledge base.


3. Long-Term Memory (MEMORY.md)

  • Curated
  • Small
  • High-signal only
  • Indexed and retrievable

👉 Treat as facts the agent must not forget.


When to Write Memory (simple rules)

Write to MEMORY.md if it would still be true next week.

Examples: - Decisions - Preferences - Invariants - Policies

Write to daily logs if it helps understand today.

Examples: - Refactors - Experiments - Temporary blockers

If unsure: write to daily log first, promote later.


Pre-Compaction Flush (why this exists)

Before OpenClaw compacts the session, it triggers a silent reminder.

This skill uses that moment as a Save Game checkpoint.

What happens:

  1. Durable knowledge is extracted
  2. Daily notes are written to today’s log
  3. Durable items are promoted to MEMORY.md
  4. Agent replies NO_REPLY (user never sees this)

This prevents knowledge loss without interrupting you.


Durable Memory Format (MEMORY.md)

Use IDs and tags so search works reliably.

## DEC-2026-02-04-01
type: decision
area: memory

Decision:
Session memory is retrieval-only. Disk is the source of truth.

Reason:
Session compaction is lossy. Disk memory is stable.

ID prefixes

  • DEC – Decisions
  • PREF – Preferences
  • FACT – Durable facts
  • POLICY – Rules / invariants

Retrieval Strategy (how agents should recall)

  1. Use memory_search (max ~6 results)
  2. Pick the best 1–2 hits
  3. Use memory_get with line ranges
  4. Inject the minimum text required

This keeps context small and precise.


Agent Playbook (rules for agents)

  • Prefer disk over RAM
  • Prefer MEMORY.md over daily logs for facts
  • Use search before asking the user again
  • Never copy raw chat into memory
  • Write memory explicitly, do not assume it sticks

Anti-Patterns (do not do these)

  • ❌ Copy chat transcripts into memory
  • ❌ Store secrets or credentials
  • ❌ Treat daily logs as long-term memory
  • ❌ Overwrite memory files instead of appending
  • ❌ Store speculation as fact

Privacy Rules

  • Never store secrets (API keys, tokens, passwords)
  • Ignore anything inside <private>...</private>
  • If sensitive info exists: store only that it exists, not the value

Retention & Cleanup

Default: no deletion

  • Disk is cheap
  • Recall quality is expensive

Optional: - Move old daily logs to memory/archive/YYYY-MM/ - Only prune after durable knowledge is verified


Usage (human-friendly)

Examples that work well: - “Store this as a durable decision.” - “This is a preference, remember it.” - “Write this to today’s log.”


Design Philosophy

  • Disk is truth
  • RAM is convenience
  • Retrieval beats retention
  • Fewer tokens > more tokens
  • Memory should earn its place
