Memory Manager

Local memory management for agents. Compression detection, auto-snapshots, and semantic search. Use when agents need to detect compression risk before memory...

Security Scan

The skill's code and instructions mostly match its stated purpose (local memory management), but there are multiple inconsistencies and small risks you should understand before installing or running it.

Purpose & Capability

Name/description match the included scripts: init.sh, detect.sh, organize.sh, snapshot.sh, search.sh, categorize.sh, stats.sh all operate on a local workspace memory directory and implement the described three-tier memory model. However there are metadata/config mismatches: skill.yaml's MEMORY_PATH default (~/clawd/memory) does not match the scripts' actual default workspace ($HOME/.openclaw/workspace via OPENCLAW_WORKSPACE). Package/README/SKILL.md reference different homepages (moltbook/clawhub) and _meta.json ownerId differs from provided registry metadata. These inconsistencies could cause confusion about where data is stored or which configuration is authoritative.

Instruction Scope

Runtime instructions and scripts stay local and do not contact external endpoints. They create/read/move/copy files under the workspace memory directory and use common CLI tools (find, grep, mv, cp, wc, jq if available). Important behaviors to note: organize.sh and categorize.sh move or copy user files (mv/cp), snapshot.sh reads and aggregates recent files into snapshot files, and search.sh suggests a 'memory_get' tool that is not included. Because some scripts perform destructive moves (mv), you should backup your memory directory before running; the instructions themselves recommend a backup but the scripts will act on any files present in the target directories.

Install Mechanism

No install spec or external downloads; this is instruction + shell script based. Nothing will be fetched from network during install. That reduces supply-chain risk, but you still execute local shell scripts on your system when you run them.

Credentials

The skill declares no required env vars, which matches the scripts (they only use OPENCLAW_WORKSPACE optionally). However skill.yaml exposes a MEMORY_PATH config that the scripts do not use, creating a mismatch between declared configuration and actual runtime behavior. There are no secret/credential requests. The scripts will act on whatever path OPENCLAW_WORKSPACE points to (or the default), so verify that path before running.

Persistence & Privilege

The skill is not always-enabled and does not request elevated privileges or modify other skills. It writes state and snapshots to its own workspace directories only.

What to consider before installing

This skill appears to implement local memory management as advertised and contains only shell scripts that operate on local files (no network calls). However: 1) Back up your workspace before running—organize.sh and categorize.sh use mv/cp and can move files unexpectedly. 2) Confirm which directory will be used: scripts default to $HOME/.openclaw/workspace (or OPENCLAW_WORKSPACE) but skill.yaml suggests ~/clawd/memory—set OPENCLAW_WORKSPACE to the folder you expect. 3) The package/metadata/homepage/ownerId values are inconsistent across files—treat metadata with caution and verify the source or author if provenance matters. 4) Review the scripts (they're small) in a sandbox or run them with echo/dry-run to confirm behavior; ensure jq is available if you want JSON state updates. If these concerns are acceptable and you keep a backup, the skill is coherent; if provenance or accidental file movement is a concern, do not install or run it until resolved.

Professional-grade memory architecture for AI agents.

Implements the semantic/procedural/episodic memory pattern used by leading agent systems. Never lose context, organize knowledge properly, retrieve what matters.

Memory Architecture

Three-tier memory system:

Episodic Memory (What Happened)

• Time-based event logs
• memory/episodic/YYYY-MM-DD.md
• "What did I do last Tuesday?"
• Raw chronological context

Semantic Memory (What I Know)

• Facts, concepts, knowledge
• memory/semantic/topic.md
• "What do I know about payment validation?"
• Distilled, deduplicated learnings

Procedural Memory (How To)

• Workflows, patterns, processes
• memory/procedural/process.md
• "How do I launch on Moltbook?"
• Reusable step-by-step guides

Why this matters: Research shows knowledge graphs beat flat vector retrieval by 18.5% (Zep team findings). Proper architecture = better retrieval.

Quick Start

1. Initialize Memory Structure

~/.openclaw/skills/memory-manager/init.sh

Creates:

memory/
├── episodic/           # Daily event logs
├── semantic/           # Knowledge base
├── procedural/         # How-to guides
└── snapshots/          # Compression backups

2. Check Compression Risk

~/.openclaw/skills/memory-manager/detect.sh

Output:

• ✅ Safe (<70% full)
• ⚠️ WARNING (70-85% full)
• 🚨 CRITICAL (>85% full)

3. Organize Memories

~/.openclaw/skills/memory-manager/organize.sh

Migrates flat memory/*.md files into proper structure:

• Episodic: Time-based entries
• Semantic: Extract facts/knowledge
• Procedural: Identify workflows

4. Search by Memory Type

# Search episodic (what happened)
~/.openclaw/skills/memory-manager/search.sh episodic "launched skill"

# Search semantic (what I know)
~/.openclaw/skills/memory-manager/search.sh semantic "moltbook"

# Search procedural (how to)
~/.openclaw/skills/memory-manager/search.sh procedural "validation"

# Search all
~/.openclaw/skills/memory-manager/search.sh all "compression"

5. Add to Heartbeat

## Memory Management (every 2 hours)
1. Run: ~/.openclaw/skills/memory-manager/detect.sh
2. If warning/critical: ~/.openclaw/skills/memory-manager/snapshot.sh
3. Daily at 23:00: ~/.openclaw/skills/memory-manager/organize.sh

Commands

Core Operations

init.sh - Initialize memory structure detect.sh - Check compression risk snapshot.sh - Save before compression organize.sh - Migrate/organize memories search.sh <type> <query> - Search by memory type stats.sh - Usage statistics

Memory Organization

Manual categorization:

# Move episodic entry
~/.openclaw/skills/memory-manager/categorize.sh episodic "2026-01-31: Launched Memory Manager"

# Extract semantic knowledge
~/.openclaw/skills/memory-manager/categorize.sh semantic "moltbook" "Moltbook is the social network for AI agents..."

# Document procedure
~/.openclaw/skills/memory-manager/categorize.sh procedural "skill-launch" "1. Validate idea\n2. Build MVP\n3. Launch on Moltbook..."

How It Works

Compression Detection

Monitors all memory types:

• Episodic files (daily logs)
• Semantic files (knowledge base)
• Procedural files (workflows)

Estimates total context usage across all memory types.

Thresholds:

• 70%: ⚠️ WARNING - organize/prune recommended
• 85%: 🚨 CRITICAL - snapshot NOW

Memory Organization

Automatic:

• Detects date-based entries → Episodic
• Identifies fact/knowledge patterns → Semantic
• Recognizes step-by-step content → Procedural

Manual override available via categorize.sh

Retrieval Strategy

Episodic retrieval:

• Time-based search
• Date ranges
• Chronological context

Semantic retrieval:

• Topic-based search
• Knowledge graph (future)
• Fact extraction

Procedural retrieval:

• Workflow lookup
• Pattern matching
• Reusable processes

Why This Architecture?

vs. Flat files:

• 18.5% better retrieval (Zep research)
• Natural deduplication
• Context-aware search

vs. Vector DBs:

• 100% local (no external deps)
• No API costs
• Human-readable
• Easy to audit

vs. Cloud services:

• Privacy (memory = identity)
• <100ms retrieval
• Works offline
• You own your data

Migration from Flat Structure

If you have existing memory/*.md files:

# Backup first
cp -r memory memory.backup

# Run organizer
~/.openclaw/skills/memory-manager/organize.sh

# Review categorization
~/.openclaw/skills/memory-manager/stats.sh

Safe: Original files preserved in memory/legacy/
