ii-commons

ii-commons is a skill for Claude Code, Codex from fabioc-aloha/Alex_Skill_Mall. It costs 29 tokens per session (891 once invoked), scanned A, original, MIT.

A search tool for research agents covering arXiv, PubMed and PMC, and selected United States policy documents. arXiv is a repository of research preprints, while PubMed and PMC index biomedical research and full-text articles.

In plain words
What is it for?
Use it to search scientific papers and policy documents, check how current a searchable collection is, retrieve paper details or full text in Markdown, and compare research evidence with policy sources.
Why use it?
It makes searches repeatable and provides stable metadata, document text, and freshness information when recent evidence matters.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ii-commons scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 exactly this command shape:

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

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

Use stable identifiers from search results:

npx @intelligentinternet/ii-commons meta "arXiv:2402.03578"
npx @intelligentinternet/ii-commons markdown "PMCID:PMC11152602"

Build summaries from search results first, then request Markdown when detailed inspection or full-document grounding is needed.

Installation

Run the CLI with npx:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ii-commons is a skill published in the GitHub repository fabioc-aloha/Alex_Skill_Mall (4 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 891 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
