baidu scholar search (1)

**Quick judgment**: This skill is a thin Bash-based wrapper around the Baidu Scholar API, suitable for basic integration of Baidu academic search (Chinese + English literature) into automated workflows. However, the current implementation contains clear parameter-handling bugs that will likely prevent successful calls without modification. **Strengths** - Direct access to Baidu Scholar’s search endpoint with support for keywords, pagination, and optional abstracts. - Good for Chinese-language and mixed-language academic discovery across journals, conferences, and theses. - Simple dependency footprint (curl + environment variable) and straightforward HTTP GET usage. **Key technical issues / risks** - Script bugs: - Uses `WD` as the actual query variable but checks `wd` for emptiness (`[ -z "$wd" ]`), which will always trigger the "Missing wd parameter" error even when input is provided. - Defaulting of `enable_abstract` incorrectly reuses the `pageNum` variable (`if [ -z "$pageNum" ]; then enable_abstract=false fi`), so the abstract flag may not behave as intended. - Hard failure if `BAIDU_API_KEY` is not set; no fallback or detailed diagnostics. - Reliability fully depends on Baidu’s API availability, rate limits, and key validity. - No built-in retry, error parsing, or response validation; any HTTP/network issues must be handled by the caller. **Safety considerations** - Low inherent safety risk: it performs read-only literature search against Baidu’s API. - Main concerns are privacy of query terms (sent to Baidu) and potential exposure of the `BAIDU_API_KEY` if logs are not handled carefully. **Recommended scenarios** - You need to integrate Baidu Scholar search into a research assistant or pipeline and are comfortable fixing minor Bash bugs and handling errors yourself. - You primarily target Chinese academic content (or bilingual searches) and want structured metadata (titles, optional abstracts, keywords). **Less suitable for** - Production-grade systems that require strong error handling, retries, and robust parameter validation without further development. - Users who are not comfortable editing Bash scripts to fix the current implementation issues.
