Note to self: don't go away for the weekend without HN ;-)

Personally I run several agents. At minimum Codex and Claude, so they cross-check each other. Exactly to avoid what you describe. Duplicate functions or "tests all pass" when nothing was implemented is the kind of thing a second model, reading the diff with fresh eyes, tends to flag immediately.

But it takes coordination and solid skills + rules to make it work. Tomorrow's battle -> AI skillers.
