## Tools (as reported by the server, not verified)

- `find\_evidence`: Use this when someone asks what a supplement, nutrient, drug, food compound or plant does in the body, or whether it affects something specific \(for example "does magnesium help sleep?", "what is creatine shown to do?", "omega-3 and triglycerides"\). Pass the substance \(or an outcome such as "sleep"\)
- `search\_nodes`: Search the Catalyst evidence graph by name or synonym \(for example "magnesium", "vitamin D", "sleep", "creatine"\). Returns node ids to pass to get\_findings or get\_relations. Each hit says how many findings it has, and hits with findings come first, so the first hit with findings above 0 is usually t
- `get\_findings`: The curated study findings for one node: for a compound, organism or material, what it has been shown to affect; for an outcome, which compounds have been studied against it. summary lists everything the node has findings about, one row each, across ALL its findings and not only the rows returned. U
- `get\_finding`: One finding by its id \(the last part of a permalink, /e/\{id\}\): the claim, its evidence strength and what that level means, the verbatim quote, the study design and the paper, and evidence\_strength\_reasons: each rule that set the level, in order, and what the assessment does not weigh. Use it to expl
- `get\_relations`: What public reference databases \(Reactome, UniProt, Rhea, ChEBI and others\) record about a node: transporters, enzymes, pathways, expression. Every row is assertion\_class 'inferred': a hypothesis about how a compound could act, not a result anyone measured in people. Present these as possible mechan
- `get\_reactions`: Biochemical reactions from Rhea and Human-GEM that a compound is a substrate or product of, or that a protein catalyses or transports. Every row is assertion\_class 'inferred': a reaction two public databases record, not a result anyone measured in a person. Present these as known biochemistry, never
- `reach`: Breadth-first reachability through the reactions two public databases \(Rhea, Human-GEM\) record: what a compound could become, and through which reactions and enzymes, within up to 3 steps. Every route is assertion\_class 'inferred': a hypothesis drawn from reference databases, never a measured or rep
