What it does

When explicitly asked for a Judgment Day or dual/adversarial review of a concrete target, the agent builds a fixed snapshot of that target and has two independent, read-only reviewer sub-agents examine it in parallel using the same criteria. It merges their findings into a shared ledger, asks before fixing, and only corrects issues that both reviewers confirm as severe. It then re-checks just those fixes, allowing at most two fix-and-recheck rounds before ending in either APPROVED or ESCALATED for a human decision. It does not grant any permission to commit, push, open PRs, or release.

Great for

  • Developers who want a second, independent-style review of a specific change or file before relying on it
  • Teams experimenting with multi-agent review workflows that need a bounded, auditable process

Skip it if

  • Routine everyday code review, since it spawns multiple sub-agents and is heavier than ordinary review; the skill itself says not to combine it with the standard review method for the same target
  • Anything expecting the review to authorize delivery: the skill explicitly issues no receipt and satisfies no commit, push, PR, or release gate

Try asking

  • “Run judgment day on the authentication changes in src/auth before we merge”
  • “Do a dual adversarial review of this migration script”
  • “Juzgar the new payment module”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Name a concrete target (file, diff, or module) so the agent does not stop to ask a scope question.
  • Expect a confirmation prompt before any fixes are applied; answer it deliberately.
  • Treat ESCALATED results as a required human decision, not a failure to retry.
