• •OpenAI Codex documentation remains devoid of a native 'exclude' function for sensitive directories or file types, according to the official GitHub repository issue #2847.
• •Developers on Hacker News noted that the absence of .gitignore-like functionality for AI training/indexing creates significant compliance and security friction.
• •It remains unconfirmed whether OpenAI plans to implement file-level filtering or if the product's architecture will continue to require external pre-processing to ensure data safety.

The GitHub issue tracker for OpenAI Codex highlights an ongoing technical limitation where users cannot natively exclude sensitive files from being indexed or processed. While many modern development tools integrate standard exclusion patterns like .gitignore to protect secrets, Codex currently lacks an analogous safeguard. Users are reportedly forced to manage sensitive data manually outside the tool, creating significant security overhead for enterprise-scale deployments. Whether OpenAI will prioritize this feature remains unclear, but its absence effectively limits the tool's adoption in environments where data privacy compliance is non-negotiable.
