Novelty Check Skill

Check whether a proposed method/idea has already been done in the literature: $ARGUMENTS

Constants

• External cross-model verifier (Codex / mcp__codex__codex) is UNAVAILABLE in this environment — persistent 401 Unauthorized (no OpenAI bearer). Do not block on it and do not silently skip verification when it fails.
• EVALUATOR = Claude itself, acting as an impartial, adversarial referee (Phase C). If Codex ever comes back, it may serve as an optional second opinion only.
• Scoring is anchored to the calibration rubric in Phase D.0 to prevent the score inflation observed when the Codex backend was down (2026-05: several econfin ideas were rated "9" but on rigorous re-check were 5–7.5).

Instructions

Given a method description, systematically verify its novelty:
