II-Commons
Overview
II-Commons provides deterministic retrieval for research agents across arXiv, PubMed/PMC, and supported US policy corpora. Use it when a task needs reproducible search, metadata lookup, full-document Markdown retrieval, or a freshness check before answering with recent evidence.
The upstream project publishes a Node.js CLI as @intelligentinternet/ii-commons and a full agent skill at skills/ii-commons/.
When to Use This Skill
- Use when searching arXiv, PubMed/PMC, or supported US policy corpora for evidence.
- Use when the user asks for latest or recent research and corpus freshness matters.
- Use when you need stable identifiers, metadata, or full-document Markdown for downstream analysis.
- Use when comparing evidence across scientific literature and policy documents.
How It Works
Step 1: Check Corpus Freshness
Run cutoff before freshness-sensitive searches:
npx @intelligentinternet/ii-commons cutoff
Report the relevant cutoff date before interpreting recent results.
Step 2: Search the Right Corpus
Use this argv shape. Literal examples can be typed as shown, but when the query
comes from a user prompt, pass it as an argument array through the runner API
instead of interpolating it into a shell string. Double quotes do not protect
against command substitution in generated shell commands.
npx @intelligentinternet/ii-commons search arxiv "large language model inference" --max-results 10
npx @intelligentinternet/ii-commons search pubmed "type 2 diabetes review" --start 20240000 --max-results 10
npx @intelligentinternet/ii-commons search policy "state overtime rule for agricultural workers" --jurisdictions US-CA --max-results 10
spawnSync("npx", [
"@intelligentinternet/ii-commons",
"search",
"arxiv",
userQuery,
"--max-results",
"10",
]);
Choose arxiv for preprints and technical research, pubmed for biomedical and clinical literature, and policy for supported US policy corpora.
Step 3: Retrieve Metadata or Markdown
