Feature Request: Allow/Deny Command Lists in Approval Workflow

[JamesR404v2]

Hi Codex CLI team,

Thanks for running such a useful tool. One pain point with the
approval system is that there’s no way to configure per-command
behavior. I often have to approve dozens of repetitive, low-risk
commands (e.g., git status, ls, cat file) and it becomes tedious to
babysit the session. On the flip side, if I select “allow everything,”
I lose any ability to keep an extra guardrail around sensitive
commands like rm -rf or git reset --hard.

A Configurable Allow/Deny List Could Help:

• Let me whitelist specific commands or patterns so they execute
  automatically even when the approval policy is otherwise strict.
• Let me blacklist commands or patterns so that, even in “allow
  everything” mode, they still prompt for approval (or are blocked
  entirely).

A simple configuration file (e.g., JSON/YAML) or CLI flags would
let users tailor the flow to their risk tolerance. Optional logging
when a rule is hit would make auditing easy. This keeps the default
behavior intact while improving UX for power users who need both speed
and safeguards.

Appreciate your consideration!
