# OpenClaw Memory System

Three components for agent memory:

1. **ALMA** — Evolves memory designs through mutation + evaluation (offline)
2. **Observer** — Extracts structured facts from conversations via LLM API (requires API key)
3. **Indexer** — Full-text search over workspace Markdown files (offline)

## Environment Variables

Observer requires one of:
- `OPENAI_API_KEY`
- `ANTHROPIC_API_KEY`
- Or pass `apiKey` in config

ALMA and Indexer require no keys or network access.

## How It Works

### ALMA (Algorithm Learning via Meta-learning Agents)
Proposes memory system designs, evaluates them, keeps the best. Uses gaussian mutation and simulated annealing to explore the design space.

```
alma.propose() → design
alma.evaluate(design.id, metrics) → score  
alma.best() → top design
alma.top(5) → leaderboard
```

### Observer
Sends conversation history to an LLM, gets back structured facts:
- Kind: world fact / biographical / opinion / observation
- Priority: high / medium / low
- Entities: mentioned people/places
- Confidence: 0.0–1.0 for opinions

Fails gracefully — returns empty array if LLM is unavailable.

### Indexer
Chunks workspace Markdown files and indexes them for search:
- `MEMORY.md` — core facts
- `memory/YYYY-MM-DD.md` — daily logs
- `bank/entities/*.md` — entity summaries
- `bank/opinions.md` — beliefs with confidence

```
indexer.index() → count of chunks indexed
indexer.search('query') → ranked results
indexer.rebuild() → re-index from scratch
```

## Install

```bash
npm install @artale/openclaw-memory
```

## Limitations

- Indexer uses an in-memory mock database, not real SQLite FTS5. Search works but ranking is simplified.
- Observer calls remote APIs — not offline. Only ALMA and Indexer work without network.
- No dashboard — removed in v2 for simplicity.

# openclaw-memory

Memory system for OpenClaw agents. Three components:

- **ALMA** — meta-learning optimizer that evolves memory designs
- **Observer** — extracts structured facts from conversations via LLM (OpenAI/Anthropic/Gemini)
- **Indexer** — full-text search over workspace Markdown files

## Install

```bash
npm install @artale/openclaw-memory
```

## Usage

```typescript
import { ALMAAgent, ObserverAgent, MemoryIndexer } from '@artale/openclaw-memory';

// ALMA: evolve memory designs
const alma = new ALMAAgent({
  constraints: { chunkSize: { min: 100, max: 1000, type: 'number' } }
});
const design = alma.propose();
alma.evaluate(design.id, { accuracy: 0.9, speed: 0.8 });
console.log(alma.best());

// Observer: extract facts (requires LLM API key)
const observer = new ObserverAgent({
  provider: 'anthropic',  // or 'openai' or 'gemini'
  apiKey: process.env.ANTHROPIC_API_KEY,
});
const facts = await observer.extract([
  { role: 'user', content: 'Alice prefers TypeScript over Python' }
]);

// Indexer: search workspace files
const indexer = new MemoryIndexer({ workspace: './my-workspace' });
indexer.index();
const results = indexer.search('TypeScript');
```

## Environment Variables

Observer requires an LLM API key (one of):
- `OPENAI_API_KEY` — for OpenAI provider
- `ANTHROPIC_API_KEY` — for Anthropic provider

ALMA and Indexer work fully offline with zero dependencies.

## OpenClaw Skill

Drop into your workspace to use as a skill:
```bash
cd ~/.openclaw/workspace/skills
git clone https://github.com/arosstale/openclaw-memory
```

## Architecture

- **5 source files, 578 lines, 0 runtime dependencies**
- In-memory database (no native modules, works everywhere)
- Observer calls remote LLM APIs when configured — not offline
- ALMA and Indexer are fully offline
