What xAI's Grok Build CLI Actually Sends to xAI

xAI's Grok Build CLI sends unredacted file contents, including .env secrets files, to xAI servers through two channels: the live model API and a session state archive uploaded to cloud storage. Additionally, the tool uploads the entire repository—including all tracked files and git history—regardless of which files the AI agent actually accesses, as demonstrated by uploading a complete git bundle even when instructed not to read specific files.
