Gitea Bot
----------

This repository contains a Python-based Gitea bot that listens for pull request events and posts an automated review when the bot account is requested as a reviewer. The bot uses a configurable Google AI Studio / Gemini REST endpoint to generate review text.

Files added:
- [gitea_bot/main.py](gitea_bot/main.py#L1) - FastAPI webhook server
- [gitea_bot/gitea_client.py](gitea_bot/gitea_client.py#L1) - minimal Gitea API helper
- [gitea_bot/gemini_client.py](gitea_bot/gemini_client.py#L1) - wrapper for Google AI Studio REST endpoint
- [Dockerfile](Dockerfile) - container image
- [requirements.txt](requirements.txt) - Python deps

Quick setup

1. Build the Docker image:

```bash
docker build -t gitea-bot:latest .
```

2. Run the container (example):

```bash
docker run -e GITEA_API_URL="https://gitea.example.com/api/v1" \
  -e GITEA_TOKEN="${GITEA_TOKEN}" \
  -e BOT_USERNAME="your-bot-username" \
  -e GOOGLE_AI_ENDPOINT="https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-flash:generateContent" \
  -e GOOGLE_API_KEY="YOUR_KEY" \
  -p 8000:8000 gitea-bot:latest
```

3. Configure a webhook in your Gitea repository pointing to `http://<host>:8000/webhook` and enable the `pull_request` event. When you request a review from the bot account the service will fetch the PR diff and post a review comment.

Notes & configuration
- Set `GITEA_API_URL` to your Gitea API base (usually `https://gitea.example.com/api/v1`).
- The bot posts a single comment on the PR; for per-line review comments the Gitea API endpoint may differ and needs adjustment in `gitea_client.py`.
- Configure `GOOGLE_AI_ENDPOINT` and `GOOGLE_API_KEY` to point to your Generative AI Studio model endpoint.

Security
- Keep `GITEA_TOKEN` and `GOOGLE_API_KEY` secret and prefer injecting via environment or secret manager.
