Multi-source literature search, citation verification, MeSH search strategy, citation file management (.nbib/.ris/.bib conversion), and reference management (BibTeX, related articles, ID conversion)…

  • The user needs coordinated multi-step literature workflows beyond a single MCP call
  • SKILL.md covers MCP Tools, Source Routing, Workflows and Shared Modules, plus 3 more sections
  • Runs Python and Shell scripts from its folder; calls python; needs SEMANTIC_SCHOLAR_API_KEY and NCBI_API_KEY
  • Tasks that involve Academic paper search

What it does

Nature Academic Search is an agent skill from jing1312/nature-figure-skill. Multi-source literature search, citation verification, MeSH search strategy, citation file management (.nbib/.ris/.bib conversion), and reference management (BibTeX, related articles, ID conversion) via MCP tools (PubMed, CrossRef, arXiv). Use when the user needs coordinated multi-step literature workflows beyond a single MCP call.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 43 other files, including scripts and reference files (for example `README.md`, `config/mcp-snippet.json` and `config/settings-snippet.json`).

It sits in Research & Science, covering Academic paper search and Citation management. It works with PubMed, Model Context Protocol, arXiv and LaTeX. The repository describes itself as: 追求每一张图的完美,支持直接修改图片,让每一张图都经得起审稿人的追问. The licence is MIT.

When your agent uses it

  • The user needs coordinated multi-step literature workflows beyond a single MCP call
  • Tasks that involve Academic paper search
  • Tasks that involve Citation management

Example prompts

  • “/nature-academic-search”

Requirements

  • Python 3
  • A Bash shell
  • A credential in SEMANTIC_SCHOLAR_API_KEY
  • A credential in NCBI_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit af77802. 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

    Ships 1 file in scripts/ (Python and Shell, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • api.semanticscholar.org
    • ncbi.nlm.nih.gov

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SEMANTIC_SCHOLAR_API_KEY
    • NCBI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Nature Academic Search loads about 1.3k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 409 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:92
    Set via `export` or `.env` file.

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); the scripts in this folder are not scanned.

Run before batch operations to verify API endpoints are reachable.

Format Converter Dependencies

The format converter (scripts/format-converter.py) uses Python stdlib only — no extra dependencies. Run python scripts/format-converter.py --test to verify the conversion pipeline.

Error Handling

  • MCP tool unavailable: report specific failure, continue with remaining tools.
  • No results: broaden terms, try alternative sources, suggest user refine query.
  • Script failure (2x): fall back to manual generation from MCP-fetched metadata.

Limitations

  • Google Scholar and Semantic Scholar are scraped (not API-backed) — results may vary.
  • Chinese literature (CNKI / 万方) not indexed by CrossRef or PubMed.
  • Citation counts may be delayed (CrossRef updates monthly).

With the skills CLI, run `npx skills add jing1312/nature-figure-skill --skill nature-academic-search -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/nature-academic-search, .gemini/skills/nature-academic-search, .github/skills/nature-academic-search and .opencode/skills/nature-academic-search in your project.

What does Nature Academic Search need to run?

Going by SKILL.md and its folder, Nature Academic Search needs Python and a shell for the scripts in its folder, the command-line tools its instructions call (python) and credentials named SEMANTIC_SCHOLAR_API_KEY and NCBI_API_KEY. Our summary lists: Python 3; A Bash shell; A credential in SEMANTIC_SCHOLAR_API_KEY; A credential in NCBI_API_KEY.

Does Nature Academic Search access the network?

SKILL.md names 2 domains. As links in the text: api.semanticscholar.org and ncbi.nlm.nih.gov. This is read from the text; nothing was executed.

Is Nature Academic Search safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Nature Academic Search use?

Nature Academic Search is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Nature Academic Search use?

About 1.3k tokens (SKILL.md is roughly 5.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 9.9k tokens, read only when the agent opens those files.
