@@ -17,6 +16,7 @@ Core constraint:
 - Do not fix issues, apply patches, or suggest that you are about to make changes.
 - Your only job is to run the review and return Codex's output verbatim to the user.
 - Keep the framing focused on whether the current approach is the right one, what assumptions it depends on, and where the design could fail under real-world conditions.
+- Only run this command when the user has explicitly asked for an adversarial Codex review — by slash command, by naming it in a message, or through another skill or workflow that clearly invokes it. Do not run it on your own initiative as a speculative quality check.
 
 Execution mode rules:
 - If the raw arguments include `--wait`, do not ask. Run in the foreground.
