What it does
Lit Review is an agent skill from GRIND-Lab-Core/night_owl_research_agent. Retrieves papers from local folder or ArXiv and Semantic Scholar using domain-aware keyword expansion, builds synthesis matrix, identifies gaps. Calls tools/arxivfetch.py and tools/semanticscholarfetch.py. Writes to output/paper-cache/ and output/LITREVIEWREPORT.md.
Its SKILL.md is about 3.2k 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. It works with arXiv, Semantic Scholar, Obsidian and Zotero. 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…

- “Use the lit-review skill to retrieve papers from local folder or ArXiv and Semantic Scholar using domain-aware keyword expansion, builds synthesis…”
- “/lit-review”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Search (external)

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
Shell commands in SKILL.md call:
python3
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
Lit Review loads about 3.2k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 1,436 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 1,436 words (~3,222 tokens).
“You perform a targeted literature review for $ARGUMENTS. Your outputs feed idea discovery and paper writing. This skill checks multiple sources in priority order. All are optional — if a source is not configured or not requested, skip it silently.”
