At a glance
Validates that a research idea is genuinely novel vs. An agent skill from GRIND-Lab-Core/night_owl_research_agent.
- Works in 4 steps: Identify Key Claims → Search → Evaluate → …

- SKILL.md covers Constants, Phase 1: Identify Key Claims, Phase 2: Search and Phase 3: Evaluate, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Novelty Check is an agent skill from GRIND-Lab-Core/night_owl_research_agent. Validates that a research idea is genuinely novel vs. existing literature. Searches ArXiv, Semantic Scholar, and WebSearch for near-duplicate work. Produces a novelty verdict and evidence. Run on each idea from idea-discovery-pipeline before investing in experiments.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Academic paper search, Creative writing and fiction and Literature review. It works with arXiv, Semantic Scholar, OpenAI and Model Context Protocol. The repository describes itself as: Fully automatic AI research agent for Geoscientists, Remote Sensing researchers, and GIScientists. Features harness engineering, GeoBenchmark (OLS/GWR/MGWR), journal templates…
When your agent uses it
- Tasks that involve Academic paper search
- Tasks that involve Creative writing and fiction
- Tasks that involve Literature review
Example prompts
- “Use the novelty-check skill to validate that a research idea is genuinely novel vs. An agent skill from GRIND-Lab-Core/night_owl_research_agent”
- “/novelty-check”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Identify Key Claims
- Search
- Evaluate
- Novelty Report
What it can do on your machine
Read from SKILL.md and the folder at commit 5f7a246. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Novelty Check loads about 1k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 396 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 396 words (~1,004 tokens).
“You verify that a research idea,$ARGUMENTS , has not already been published in substantially equivalent form.”
