That issue surfaced two primary use cases: preventing sensitive data from being sent to the model and excluding large/irrelevant files. The issue was closed in favor of a Rust (codex-rs) implementation, but as of 2025-08-28 a comparable feature does not appear to exist in codex-rs. I’d like to restart the discussion and converge on a design.
