Remove the OpenAI API key from build arguments—it's only needed at runtime.

The API key is passed as a build ARG and then set as an ENV, but it's never actually consumed during the build process. Embeddings are generated at runtime in src/embeddings.js, not during Docker image build. The build-time ARG is unnecessary and could expose the key in build history.

Recommendation: Remove lines 33-34 and rely only on the API key being provided at container runtime (which is how it's already reset in the prod stage on line 54).

🤖 Prompt for AI Agents 
In Dockerfile around lines 33-34, remove the build ARG and ENV for
_APP_ASSISTANT_OPENAI_API_KEY because the key is not used during image build and
should only be provided at runtime; delete the two lines declaring ARG
_APP_ASSISTANT_OPENAI_API_KEY and ENV
_APP_ASSISTANT_OPENAI_API_KEY=${_APP_ASSISTANT_OPENAI_API_KEY} so the secret is
not leaked into build history and rely on the existing runtime provision (as
done in the prod stage at line 54).

## Installation

Make sure you have [pnpm](https://pnpm.io/) installed.
Make sure you have [Bun](https://bun.sh) installed.

To install, run the following command.

```bash
pnpm i
bun install
```

Next, fetch the Appwrite-specific sources used by the assistant. This will download the sources from the Appwrite documentation and store them in the `./sources` directory.

```bash
pnpm run fetch-sources
bun run fetch-sources
```

The scripts will pull the latest documentation from the `main` branch of the [website repository](https://github.com/appwrite/website), and the latest API reference from live [Appwrite documentation](https://appwrite.io/docs).
The scripts will pull the latest documentation from the `main` branch of the [website repository](https://github.com/appwrite/website), and the latest API reference from live [Appwrite documentation](https://appwrite.io/docs).

If you want to pull from a different branch or repository, you can set the `_BUILD_GIT_URL` and `_BUILD_WEBSITE_URL` environment variables.

## Usage

First, retrieve an API key from OpenAI. You can sign up for an API key at [OpenAI](https://beta.openai.com/signup/). Once you have an API key, set it as the `_APP_ASSISTANT_OPENAI_API_KEY` environment variable.

To run the server, execute the `dev` command. By default, the server will be available at `http://localhost:3003`

The server exposes a POST endpoint at `/`. The endpoint expects a raw text body containing the query for the assistant. The answer to the query will be streamed back to the client as raw text.
