Source Routing

数据源路由

See Source Tiers & Reliability for the complete reliability classification and fallback routing rules. The T1→T2→T3 fallback chain is the standard execution order across all workflows.

Pre-flight Check

预检查

bash
python scripts/preflight.py
Run before batch operations to verify API endpoints are reachable.
bash
python scripts/preflight.py
批量操作前运行该脚本，验证API端点是否可达。

Format Converter Dependencies

格式转换器依赖

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.
格式转换器（
scripts/format-converter.py
）仅使用Python标准库——无需额外依赖。运行
python scripts/format-converter.py --test
验证转换流程。

Error Handling

错误处理

  • 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.
  • MCP工具不可用：报告具体失败信息，继续使用剩余工具。
  • 无检索结果：扩大检索词范围，尝试替代数据源，建议用户优化查询词。
  • 脚本连续失败2次：从MCP获取的元数据中手动生成结果。

Limitations

局限性

  • 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).
  • Google Scholar和Semantic Scholar为抓取数据（非API支持）——结果可能存在差异。
  • 中文文献（CNKI / 万方）未被CrossRef或PubMed收录。
  • 引用次数可能存在延迟（CrossRef每月更新一次）。
