# Reindex Skill

Rebuild the vector search index from all summary files in the knowledge base.

## Usage

```
/reindex [--force]
```

**Examples:**
```
/reindex
/reindex --force
```

## Parameters

| Parameter | Description |
|-----------|-------------|
| `--force` | Delete existing index and rebuild from scratch |

## When to Use

- **Incremental update (no flag):** After adding new videos, updates the index with new content while preserving existing embeddings
- **Force rebuild (`--force`):** When you want to regenerate all embeddings, fix corruption, or after modifying the chunking logic

## Instructions

### Step 1: Execute Indexer

Run the indexer from the project root:

```bash
cd /Users/ryankwong/high-powered-engineer && python3 vector-search/indexer.py [--force]
```

### Step 2: Report Results

The indexer outputs stats. Report to user:
- Total chunks indexed
- Chunks added (new)
- Chunks updated (modified)
- Chunks deleted (removed summaries)
- Final collection size

## Error Handling

| Error | Action |
|-------|--------|
| Dependencies missing | Tell user: `pip3 install -r vector-search/requirements.txt` |
| No summaries found | Verify `summaries/` directory exists and has `.md` files |
| Permission error | Check write permissions for `vector-search/db/` |

## Technical Notes

- Index stored at `vector-search/db/`
- Embedding model: `all-MiniLM-L6-v2` (~90MB, downloaded on first run)
- Incremental updates use chunk IDs to detect changes
- Full rebuild takes ~30 seconds for ~1000 chunks
