# Note for reviewers The bulk of this PR is in in the new file, `parse_command.rs`. This file is designed to be written TDD and implemented with Codex. Do not worry about reviewing the code, just review the unit tests (if you want). If any cases are missing, we'll add more tests and have Codex fix them. I think the best approach will be to land and iterate. I have some follow-ups I want to do after this lands. The next PR after this will let us merge (and dedupe) multiple sequential cells of the same such as multiple read commands. The deduping will also be important because the model often reads the same file multiple times in a row in chunks === This PR formats common commands like reading, formatting, testing, etc more nicely: It tries to extract things like file names, tests and falls back to the cmd if it doesn't. It also only shows stdout/err if the command failed. <img width="770" height="238" alt="CleanShot 2025-08-09 at 16 05 15" src="https://github.com/user-attachments/assets/0ead179a-8910-486b-aa3d-7d26264d751e" /> <img width="348" height="158" alt="CleanShot 2025-08-09 at 16 05 32" src="https://github.com/user-attachments/assets/4302681b-5e87-4ff3-85b4-0252c6c485a9" /> <img width="834" height="324" alt="CleanShot 2025-08-09 at 16 05 56 2" src="https://github.com/user-attachments/assets/09fb3517-7bd6-40f6-a126-4172106b700f" /> Part 2: https://github.com/openai/codex/pull/2097 Part 3: https://github.com/openai/codex/pull/2110
