Lily Memory
Persistent memory plugin for OpenClaw agents. Gives your agent long-term memory that survives session resets, compaction, and restarts.
What It Does
- Auto-recall: Injects relevant memories as context before each LLM turn
- Auto-capture: Extracts facts from conversations and stores them automatically
- Hybrid search: SQLite FTS5 keyword search + Ollama vector cosine similarity
- Stuck detection: Detects topic repetition and nudges the agent to break loops
- Memory consolidation: Deduplicates entries on startup
- Dynamic entities: Config-driven allowlist + runtime tool to add entities
- Graceful degradation: Works without Ollama (keyword-only mode)
- Zero npm dependencies: Uses sqlite3 CLI + native fetch
Requirements
- Node.js 18+ (for native
fetch) - SQLite 3.33+ with FTS5 (ships with macOS;
apt install sqlite3on Linux) - Optional: Ollama with
nomic-embed-textmodel for semantic search
Quick Start
- Install the plugin to your extensions directory
- Add to your
openclaw.json:
{
"plugins": {
"slots": { "memory": "lily-memory" },
"entries": {
"lily-memory": {
"enabled": true,
"config": {
"dbPath": "~/.openclaw/memory/decisions.db",
"entities": ["config", "system"]
}
}
}
}
}
- Restart the gateway:
openclaw gateway restart

Architecture
Recall flow: Extract keywords from message -> FTS5 + vector search -> merge and deduplicate -> inject as context
Capture flow: Regex scan for entity: key = value patterns -> validate entity against allowlist -> store to SQLite -> async embed via Ollama
Stuck detection: Track top 5 content words per response -> Jaccard similarity -> if 3+ consecutive >60% overlap, inject Reflexion nudge
