idea-quality

microsoft/ResearchStudio/ResearchStudio-Idea/evaluation/idea_quality/SKILL.md

Score the QUALITY of a research idea at the idea stage — given a Markdown file with Title / Motivation / Method sections (no experiments needed), produce a per-axis quality assessment with cited evidence and an overall 0–100 score plus a verdict; or, given two such idea files, a blind head-to-head comparison. TRIGGER when the user asks "how good is this idea", "rate / score / grade this research idea or proposal", "review my idea .md before I write it up", "is this contribution strong enough to pursue", "which of these two idea files is stronger", or hands over an idea Markdown file (Title/Motivation/Method) and wants a quality judgment. Use this even when the user does not say the word "score" but clearly wants an assessment of how strong an idea is. DO NOT trigger for prior-art / overlap / "is this novel vs existing work" checks (that is a literature-collision task), for full reviews of finished papers that already have results, or for generating the idea itself.

idea-spark

microsoft/ResearchStudio/ResearchStudio-Idea/skills/idea_spark/SKILL.md

Generate ONE reviewer-defensible, implementable research idea with a concrete method and falsification plan from a stated research direction.

scoop-check

microsoft/ResearchStudio/ResearchStudio-Idea/skills/scoop_check/SKILL.md

Check whether a proposed research novelty (given a problem statement and claimed idea/novelty) overlaps with existing published work. TRIGGER when the user asks to verify research novelty, check if an idea is new, compare a proposed contribution to prior art, do a literature/prior-art search for a specific claim, or assess whether a paper idea has been scooped. DO NOT TRIGGER for general literature reviews unrelated to a specific novelty claim, or for writing related-work sections of an already-validated idea.

CLAUDE.md vs AGENTS.md

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
