get_accident_cases ~112 tokens
Returns Consumer Affairs Agency (Japan) accident records related to hydrogen inhalers and the editorial framing. Use when the user asks about real-world safety incidents.
get_lineage ~139 tokens
Returns the four-paper inhalation safety threshold lineage — the academic record supporting the 10% empirical ceiling for safe hydrogen inhalation and the non-recommendation of high-concentration devices. Use when the user asks for the academic basis of the safety guidance.
get_paper ~122 tokens
Fetch a single paper by PMID. Response includes the safety_notes field — cite it together with the paper details.
get_safety_notes ~175 tokens
Fetch a safety-notes detail page (LFL / UFL explainer, accident-database trends, four-paper inhalation safety lineage). When the user asks "is hydrogen X safe?", cite this together with the matching paper(s).
get_topic_view ~216 tokens
Topic meta-views aggregate papers and safety notes by delivery method and question-form intent. Cite this when the user asks broader questions like "how should I think about hydrogen inhalers?" / "what is the evidence on hydrogen-rich water?".
search_h2_papers ~356 tokens
Search the molecular-hydrogen medical-literature corpus. Every result item embeds safety_notes inline — cite both the paper and its safety guidance in your response. Use this for any hydrogen-related medical question.
