# openground nuke

> Delete data from OpenGround

Delete data from raw\_data and/or the LanceDB vector database. Use with caution.

<Warning>
  These commands permanently delete data and cannot be undone. Make sure you have backups or can re-extract the documentation.
</Warning>

## Commands

### all

Delete all files in both raw\_data and LanceDB directories.

```bash theme={null}
openground nuke all [OPTIONS]
```

#### Options

<ParamField path="--yes" type="boolean" default="false">
  Skip confirmation prompt.

  **Aliases:** `-y`
</ParamField>

#### Example

```bash theme={null}
openground nuke all
```

**Output:**

```
⚠ This will permanently delete ALL data:
  • Raw data: 5 libraries in /home/user/.openground/raw_data
  • Embeddings: 5 libraries in /home/user/.openground/lancedb

ℹ Tip: Run 'openground list-raw-libraries' and 'openground list-libraries' 
  to see what will be deleted.

Are you sure you want to delete ALL data? This cannot be undone! [y/N]: y

✓ Deleted raw data directory: /home/user/.openground/raw_data
✓ Deleted LanceDB directory: /home/user/.openground/lancedb

✓ Deleted all data (5 raw libraries, 5 embedded libraries).
```

### raw\_data

Delete all files in the raw\_data directory.

```bash theme={null}
openground nuke raw_data [OPTIONS]
```

#### Options

<ParamField path="--yes" type="boolean" default="false">
  Skip confirmation prompt.

  **Aliases:** `-y`
</ParamField>

#### Example

```bash theme={null}
openground nuke raw_data
```

**Output:**

```
⚠ This will permanently delete ALL raw data:
  • 5 libraries in /home/user/.openground/raw_data

ℹ Tip: Run 'openground list-raw-libraries' to see what will be deleted.

Are you sure you want to delete ALL raw data? This cannot be undone! [y/N]: y

✓ Deleted raw data directory: /home/user/.openground/raw_data

✓ Deleted 5 raw libraries.
```

### embeddings

Delete all files in the LanceDB directory.

```bash theme={null}
openground nuke embeddings [OPTIONS]
```

#### Options

<ParamField path="--yes" type="boolean" default="false">
  Skip confirmation prompt.

  **Aliases:** `-y`
</ParamField>

#### Example

```bash theme={null}
openground nuke embeddings
```

**Output:**

```
⚠ This will permanently delete ALL embeddings:
  • 5 libraries in /home/user/.openground/lancedb

ℹ Tip: Run 'openground list-libraries' to see what will be deleted.

Are you sure you want to delete ALL embeddings? This cannot be undone! [y/N]: y

✓ Deleted LanceDB directory: /home/user/.openground/lancedb

✓ Deleted 5 embedded libraries.
```

## Use Cases

### Complete Reset

Delete everything and start fresh:

```bash theme={null}
openground nuke all -y
```

### Free Disk Space (Keep Embeddings)

Delete raw data but keep embeddings:

```bash theme={null}
openground nuke raw_data -y
```

Raw data is only needed for re-embedding. Once embedded, you can safely delete it.

### Re-embed Everything

Delete embeddings but keep raw data:

```bash theme={null}
openground nuke embeddings -y
openground embed mylib  # Re-embed from raw data
```

### Before Changing Embedding Model

When switching embedding models, you must re-embed:

```bash theme={null}
# Change model
openground config set embeddings.embedding_backend fastembed
openground config set embeddings.model_name BAAI/bge-small-en-v1.5

# Delete old embeddings
openground nuke embeddings -y

# Re-embed from raw data
openground embed mylib
```

## Safety Features

### Confirmation Prompts

All commands show:

* Number of libraries to be deleted
* Directory paths
* Tips for checking what will be deleted

You must explicitly confirm unless using `--yes`.

### Count Before Delete

Before deleting, verify what exists:

```bash theme={null}
# Check raw libraries
openground list-raw-libraries

# Check embedded libraries
openground list-libraries

# Then delete
openground nuke all
```

### No Data = No Action

If directories are empty, commands report and exit:

```bash theme={null}
openground nuke all
```

**Output:**

```
No data found. Nothing to delete.
```

## What Gets Deleted

### `nuke all`

* **Raw data directory:** `~/.openground/raw_data/`
* **LanceDB directory:** `~/.openground/lancedb/`
* **Statistics:** Tool call statistics (reset to zero)
* **Query caches:** Internal query caches

### `nuke raw_data`

* **Raw data directory:** `~/.openground/raw_data/`
* All extracted JSON files

### `nuke embeddings`

* **LanceDB directory:** `~/.openground/lancedb/`
* All vector embeddings
* **Statistics:** Tool call statistics (reset to zero)
* **Query caches:** Internal query caches

## What Doesn't Get Deleted

* **Configuration file:** `~/.openground/config.json` (use `openground config reset`)
* **Sources file:** `~/.openground/sources.json`
* **MCP configurations:** Agent integration configs

## Recovery

After nuking, you can:

1. **Re-add libraries:**
   ```bash theme={null}
   openground add langchain -s https://python.langchain.com/sitemap.xml
   ```

2. **Re-embed from raw data (if available):**
   ```bash theme={null}
   openground embed mylib
   ```

3. **Restore from backup (if created):**
   ```bash theme={null}
   cp -r /backup/.openground ~/
   ```
