What it does

Ii Commons is an agent skill from sickn33/agentic-awesome-skills. Deterministic search across arXiv, PubMed/PMC, and US policy corpora with daily freshness cutoffs.

Its SKILL.md is about 1.1k 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. It works with arXiv and PubMed. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is Apache-2.0.

Requirements

Node.js

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Check Corpus Freshness
Search the Right Corpus
Retrieve Metadata or Markdown

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. 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:
- npx
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- commons.ii.inc
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- II_COMMONS_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ii Commons loads about 1.1k tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 420 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~27
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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.

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:

bash

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.

bash

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

Use stable identifiers from search results:

bash

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:

bash

npx @intelligentinternet/ii-commons --help

Or install globally:

bash

npm install -g @intelligentinternet/ii-commons
ii-commons cutoff

To install the full upstream agent skill, install the skills/ii-commons/ folder from:

https://github.com/Intelligent-Internet/II-Commons-Skills

Best Practices

Prefer server-side date filters such as --start and --end for time-bounded arXiv and PubMed searches.
Preserve canonical identifiers such as arXiv:<id>, PMID:<id>, PMCID:PMC<id>, and policy:<jurisdiction>:<id>.
Use cutoff as the authoritative freshness boundary for each corpus.
Keep non-time filters conservative until initial search results show the right scope.

Limitations

Requires Node.js 18 or newer and outbound network access to commons.ii.inc.
Basic usage works without authentication; higher usage limits may require an API token from https://commons.ii.inc/.
Supported policy coverage is limited to the policy corpora exposed by II-Commons.

Security & Safety Notes

Do not print or expose II_COMMONS_API_KEY values.
Treat outputs as retrieval evidence, not expert review. For medical, legal, or policy-sensitive work, cite sources and preserve uncertainty.
Commands call an external API service; confirm network access is allowed in the user's environment before running them.

Use broader web-search or deep-research skills when evidence is outside arXiv, PubMed/PMC, or supported policy corpora.
Use citation-management skills after II-Commons has identified stable source records.
