research

research is a skill for Claude Code from MikkoParkkola/nab. It costs 119 tokens per session (3,439 once invoked), scanned A, original, MIT.

An academic research helper that chooses among free databases of papers, authors, books, and research organisations, using paid search only when needed.

In plain words
What is it for?
Use it to find recent papers, prior work, citation information, author publications, and other academic literature.
Why use it?
It removes the guesswork of choosing where to search and helps avoid wasting paid searches when free sources may be enough.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

research 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 8d 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.

research is a skill published in the GitHub repository MikkoParkkola/nab (12 stars, last pushed yesterday), licensed MIT. It adds 119 tokens to every session and 3,439 once invoked, about $0.0006 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 2026-08-30.
