Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (6)

`get_accident_cases`read-only	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`read-only	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`read-only	Fetch a single paper by PMID. Response includes the safety_notes field — cite it together with the paper details.
`get_safety_notes`read-only	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`read-only	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`read-only	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.
