Tokens, turns and time describe resource use, not a dollar price.
This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.6-flash on 10/3/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
We are adding a verified 2024 paper authored by First Author Kim regarding AI validation in diagnostic radiology. What naming structure should be used for the BibTeX citation key?

The instructions your model reads when the skill loads.
Every reference you produce must come from a live database result — never generate a citation from memory alone, because a recalled citation can look real and not exist.
| Database | MCP Tool | Purpose |
|---|---|---|
| PubMed | mcp__claude_ai_PubMed__search_articles | Search by query, MeSH terms |
| PubMed | mcp__claude_ai_PubMed__get_article_metadata | Full metadata for a PMID |
| PubMed | mcp__claude_ai_PubMed__find_related_articles | Related articles for a PMID |
| PubMed | mcp__claude_ai_PubMed__lookup_article_by_citation | Verify a citation |
| PubMed | mcp__claude_ai_PubMed__convert_article_ids | Convert between PMID/DOI/PMCID |
| Semantic Scholar | mcp__claude_ai_Scholar_Gateway__semanticSearch | Semantic search across all fields |
| bioRxiv/medRxiv | mcp__claude_ai_bioRxiv__search_preprints | Search preprint servers |

If any mcp__claude_ai_PubMed__* call returns an error containing "terminated", "not found",
"not available", or "not connected", switch ALL subsequent PubMed calls in this session to the
bundled E-utilities scripts. Do not retry MCP after a disconnect — it will not recover within the
same conversation.
