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

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

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
