# Google Developer Knowledge

Use this skill to search and retrieve content from Google's public developer documentation corpus using the Developer Knowledge API.

This skill uses simple bash scripts with curl (no dependencies required).

## Prerequisites

2.  **Create an API Key**:
    -   Go to the [Credentials page](https://console.cloud.google.com/apis/credentials)
    -   Click **Create credentials** → **API key**
    -   Restrict the key to **Developer Knowledge API** only

3.  **Set Environment Variable**:
    -   `DEVELOPERKNOWLEDGE_API_KEY`: Your Developer Knowledge API key

## Searchable Corpus

The API searches these domains:
-   `ai.google.dev`
-   `developer.android.com`
-   `developer.chrome.com`
-   `developers.google.com`
-   `docs.cloud.google.com`
-   `firebase.google.com`
