## Overview

The `improve_component` tool generates code suggestions for a specific code component that has changed in the PR.
it can be invoked manually by commenting on any PR:

```
/improve_component component_name
```

To get a list of the components that changed in the PR and choose the relevant component interactively, use the [`analyze`](./analyze.md) tool.

## Example usage

Invoke the tool manually by commenting `/improve_component` on any PR:

![improve_component1](https://codium.ai/images/pr_agent/improve_component1.png){width=768}

The tool will generate code suggestions for the selected component (if no component is stated, it will generate code suggestions for the largest component):

![improve_component2](https://codium.ai/images/pr_agent/improve_component2.png){width=768}
