SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Before investing months into a research project, you need to know whether your method or idea has already been published. This Skill systematically checks a proposed research idea against recent literature so you avoid both false novelty claims and prematurely abandoning viable ideas. ## Core Features & Use Cases - Claim Extraction: Breaks a method description into 3-5 core technical claims that carry the claimed contribution. - Multi-Source Literature Search: Searches arXiv, Google Scholar, Semantic Scholar, and recent conference proceedings (ICLR, NeurIPS, ICML) with multiple query formulations per claim. - Cross-Model Verification: Sends a dossier of claims and candidate papers to a reviewer model via Codex MCP for an independent novelty judgment under calibrated verdict limits. - Structured Report: Produces a novelty report with closest prior work, a 1-10 score, and a PROCEED / PROCEED WITH CAUTION / ABANDON recommendation. - Use Case: You have an idea for a new attention mechanism. Run this Skill to find the closest 2024-2026 papers, verify each citation, and get a defensible positioning statement before writing any code. ## Quick Start Ask the assistant to run a novelty check on your research idea, for example by saying "check novelty of my method that combines sparse attention with curriculum learning for long-document summarization".

FAQPage Schema
How do I check if my research idea is novel?▼

Provide a description of your method or idea, and the Skill extracts 3-5 core technical claims, searches arXiv and recent conference proceedings for each claim, then produces a report with closest prior work and a novelty score from 1 to 10.

What literature sources does a novelty check cover?▼

The search covers arXiv, Google Scholar, and Semantic Scholar via web search, plus recent proceedings from ICLR 2025/2026, NeurIPS 2025, and ICML 2025/2026. It emphasizes the most recent six months of arXiv preprints since the field moves quickly.

How does the novelty verdict get decided?▼

A reviewer model called through Codex MCP evaluates a dossier of your claims and candidate papers under explicit verdict limits. ABANDON requires naming a specific published paper containing the result; crowded territory with a clear delta still yields PROCEED.

Can the novelty check hallucinate fake paper citations?▼

No. Every paper in the prior-work table must pass pre-search verification through a helper script that resolves entries against arXiv, CrossRef, and Semantic Scholar. Unverifiable entries are tagged [UNVERIFIED] rather than dropped or fabricated.

When should I not rely on a novelty check alone?▼

This check is an early triage gate, not a final judgment. A passing idea should still go through pilot experiments and external peer review, since literature search cannot guarantee that no concurrent or unpublished work exists.
