使用示例
基本检索
from agent import AcademicLiteratureSearchSkill
import asyncio
async def main():
skill = AcademicLiteratureSearchSkill()
params = {
"query": "deep learning in medical imaging",
"databases": ["semantic_scholar"],
"max_results": 10
}
result = await skill.execute(params)
print(result["results"])
asyncio.run(main())
高级检索
params = {
"query": "attention mechanism AND transformer",
"databases": ["semantic_scholar", "crossref"],
"year_range": "2020-2024",
"max_results": 100,
"sort_by": "citations",
"min_citations": 50,
"open_access_only": True,
"output_format": "markdown"
}
作为库使用
from agent import LiteratureSearchEngine
async def search():
async with LiteratureSearchEngine() as engine:
papers = await engine.search(
query="reinforcement learning",
databases=["semantic_scholar", "arxiv"],
max_results=20
)
for paper in papers:
print(f"{paper.title} - {paper.citation_count} citations")

安全与隐私
数据流向
- 检索查询会发送到第三方API:Semantic Scholar、Crossref、PubMed、arXiv
- 搜索关键词和论文元数据会被发送到这些服务
建议
- 使用虚拟环境运行:
python -m venv venv && source venv/bin/activate - 设置自己的 API 密钥以使用您的凭证
- 默认使用 [email protected] 作为 Crossref 邮箱
- 缓存目录:~/.cache/openclaw/literature
隐私
- 如需高隐私保护,避免使用默认凭证
- 可在代码中审查网络请求目的地
Usage Guidance
This skill appears consistent with its stated purpose. Before installing: (1) review the full agent.py (the provided snippet is long—ensure no hidden endpoints or unexpected behavior), (2) run it in a virtualenv and install dependencies from requirements.txt, (3) set your own API keys (avoid default email/credentials), (4) verify the repository/homepage and version (skill.json lists version 2.0.0 while registry metadata shows 0.1.3), and (5) be aware it will contact third-party academic APIs and store cache/log files under your home directory. If you need higher assurance, inspect the entire agent.py for any network calls beyond the documented APIs and run tests in an isolated environment.
Capability Analysis
Type: OpenClaw Skill
Name: academic-literature-search
Version: 0.1.3
The skill bundle is a legitimate academic literature search tool that integrates with Semantic Scholar, Crossref, PubMed, and arXiv. The code in `agent.py` follows standard practices for asynchronous API requests and data processing, with no evidence of malicious intent, data exfiltration, or unauthorized command execution. All requested permissions and behaviors, such as network access to academic databases and local file writing for caching/results, are consistent with the tool's stated purpose.
Capability Assessment
Purpose & Capability
Name/description claim integration with Semantic Scholar, Crossref, PubMed, arXiv; the code (agent.py), SKILL.md, README, and skill.json implement HTTP clients, caching, output formatting, and configuration. Required network and file-write permissions match the stated purpose. Optional API keys are appropriate for the listed providers.
Instruction Scope
SKILL.md instructs the agent to send search queries to the documented third-party APIs, use a config file and cache directory, and optionally set API keys. It does not instruct reading unrelated system files, harvesting credentials, or calling hidden endpoints. It recommends reviewing network destinations and using your own API keys.
Install Mechanism
There is no explicit install spec (instruction-only), but the package includes code and a requirements.txt. That is not inherently malicious, but users must ensure dependencies (aiohttp, requests, pandas, pyyaml, aiofiles) are installed in a controlled environment (virtualenv). The lack of an install step means the runtime may fail if deps aren't present—this is an operational note rather than a security issue.
Credentials
Environment variables mentioned (SEMANTIC_SCHOLAR_API_KEY, CROSSREF_API_EMAIL, PUBMED_API_KEY) are optional and appropriate for the APIs used. No unrelated credentials or high-privilege env vars are requested. The code uses a cache directory under the user's home—expected for caching.
Persistence & Privilege
The skill does not request always:true and does not modify other skills or global agent settings. It writes to a local cache directory and may create log files as configured—these are reasonable for the function.
How to Use

/install academic-literature-search - After installation, invoke the skill by name or use
/academic-literature-search - Provide required inputs per the skill's parameter spec and get structured output
