nature-academic-search

nature-academic-search is a skill for Claude Code, Codex from hamzabellouch/agent-skills. It costs 211 tokens per session (1,119 once invoked), scanned A, a copy of nature-academic-search, MIT.

A research assistant for finding academic papers, checking citations, analysing who cites an article, planning MeSH searches, and converting citation files such as BibTeX, RIS, and NBIB. MeSH is the controlled vocabulary used to index biomedical literature.

In plain words
What is it for?
Use it to search across academic sources, audit citations, build citation-metric tables, extract citation context, design PubMed search strategies, and organise reference-library files.
Why use it?
It brings several literature-search and reference-management tasks into one workflow and helps verify whether citations and citation relationships are correct.

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

nature-academic-search 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.

The scan reads SKILL.md. This mod also ships 21 executable files (install.sh, mcp-server/academic_search_server.py, mcp-server/sources/__init__.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Academic Search — Router

This skill is split into two layers:

  • A static layer under static/ that holds versioned, reusable content fragments (the MCP tool inventory and shared modules, and source routing plus operational rules).
  • A dynamic layer (this file plus manifest.yaml) that detects which workflow the user needs and loads that workflow, reaching for shared modules and scripts only when a step needs them.

Do not try to apply the search logic from memory or from this router. Always load fragments from disk as described below.

Routing protocol

Follow these five steps every time the skill is invoked.

1. Load the manifest and the core layer

Read manifest.yaml. It declares the workflow axis, the allowed values, and the file paths each value maps to.

Also read every file listed under always_load:

  • static/core/tools.md — the MCP tool inventory (core search, extended search, PubMed utilities) and the shared-module map.
  • static/core/routing-and-ops.md — the T1→T2→T3 source routing quick guide, environment setup, error handling, and limitations.

2. Detect the workflow

Map the user's need to one or more workflow values:

  • multi-source-search — find literature across sources.
  • citation-verification — verify citations extracted from a document.
  • mesh-strategy — build a MeSH/PubMed search strategy.
  • citation-file-mgmt — convert/manage .nbib/.ris/.bib files.
  • reference-mgmt — BibTeX, related-article discovery, ID conversion.
  • strict-other-citation-impact-audit — determine strict independent other-citations, build article-level citation metric tables, identify high-profile citers (academy members, presidents/deans, talent-award holders, fellows, field leaders), and extract how they cited the target paper.

A combined request (for example search then export) may need more than one. State the detected workflow(s) in one short line before proceeding.

3. Load the matching workflow fragment(s)

Changes

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.
