# Memory Wiki & Vector RAG Store

> Local persistent knowledge bases for long-term agent memory search.

Hiroshi features a file-backed Memory Wiki system that chunks local markdown manuals, generates vector embeddings, and performs fast mathematical cosine similarity lookups.

### ⚙️ 1. Configurations Setup

To enable Memory Wiki search, update settings inside `config.toml`:

```toml theme={null}
[wiki]
enabled = true
wiki_dir = "~/.hiroshi/workspace/wiki"
similarity_threshold = 0.75
```

### 🛠️ 2. Execution Primitives

#### `<wiki_store>`

Index or re-index the markdown knowledge base:

```xml theme={null}
<wiki_store>/path/to/custom/wiki</wiki_store>
```

* Slices markdown blocks at paragraph boundaries (`\n\n`).
* Caches generated vector embeddings in-memory.

#### `<wiki_search>`

Search semantic vector databases using cosine dot-product similarity:

```xml theme={null}
<wiki_search>how to deploy on digitalocean</wiki_search>
```

* Generates query embedding vectors.
* Performs dot-product calculation matching chunks with scores exceeding `similarity_threshold`.
