Hack Review-A code review tool like coderabbit (github.com)

Hack Review is an open-source GitHub App that automatically analyzes pull requests by constructing a prompt from the PR title, body and file diffs, sending that prompt to Hack Club’s AI API, and posting the resulting review as a comment on the PR. The app hooks into GitHub webhooks: when a PR opens, it fetches the changed files, builds the prompt, calls the AI, and returns feedback on potential bugs, style issues, and other problems. The AI’s behavior is controlled by a modifiable System_Prompt.md, so teams can tune tone, rules, and checks. Significance for AI/ML practitioners and engineering teams is practical: it embeds AI-assisted code review directly into CI workflows, reducing manual review load and surfacing quick feedback on correctness and style. Technically, you deploy it as a GitHub App (create an app, set webhook URL and secret, grant Pull requests read/write, install on repos), store credentials in .env (WEBHOOK_SECRET, APP_ID, API_KEY, MODEL, BOT_NAME), and save the app private key as hack-review.pem. The repo runs as a Python service (python app.py) and is forkable for customization. Considerations include protecting API keys/private keys, configuring permissions, and carefully tuning the system prompt to avoid noisy or incorrect suggestions.
