Search 10 academic paper databases via their REST APIs to find research papers, preprints, and scholarly articles. Covers biomedical literature (PubMed, PMC full text), preprint servers (bioRxiv, medRxiv, arXiv), multidisciplinary indexes (OpenAlex, Crossref, Semantic Scholar), open access aggregators (CORE, Unpaywall).

Tokens, turns and time describe resource use, not a dollar price.
One of 2 test cases the skill fixed. Same model, same prompt, with and without the skill.
I am executing API requests in a terminal CLI environment where the primary web fetch tool fails or is unavailable. What command-line tool should be used as the fallback to make HTTP requests?
| Checked | Without skill | With skill |
|---|---|---|
| Recommends using curl as the fallback command-line tool | Missed | Passed |

|---|---|
| Everything about a paper (metadata + citations + OA) | Crossref + Semantic Scholar + Unpaywall |
| Comprehensive literature search | PubMed + OpenAlex + Semantic Scholar |
| Find and read a paper | PubMed (find) + Unpaywall (OA link) + PMC or CORE (full text) |

When a query spans multiple needs (e.g., "find papers about CRISPR and get me the PDFs"), query the relevant databases in parallel.
Different databases use different identifier systems. If a query fails, the identifier format may be wrong.
