Raw names from tools/list. Only developers need these.

check_cannabis_testingCheck cannabis testing limits by US state, test category, and optional analyte. Use when the user asks for pesticide, heavy metal, microbial, solvent, mycotoxin, potency, moisture, or action-level requirements for cannabis products in a specific state. Do not use for controlled-substance scheduling, Health Canada product compliance, EU precursor checks, non-cannabis food pesticide MRLs, or broad keyword discovery. The response includes testing categories, analyte names, action levels, units, product classes, jurisdiction notes, and regulation references.
check_controlled_substanceCheck controlled-substance status by substance name or CAS number across UN, EU, and NPS sources. Use when the user asks whether cannabis, THC, morphine, pseudoephedrine, a precursor, or another substance is scheduled, controlled, monitored, or listed by INCB, EU precursor rules, or EMCDDA/EUDA. Do not use for state cannabis lab testing limits, product-class compliance summaries, food/pharma safety, or generic cannabis keyword searches. The response includes schedules, categories, synonyms, CAS numbers, source datasets, and regulatory notes.
check_cannabis_complianceCheck cannabis product compliance requirements for a US state or Health Canada jurisdiction. Use when the user asks what testing categories, product classes, analyte limits, or regulatory sections apply to flower, concentrates, edibles, topicals, extracts, oils, or dried cannabis. Do not use for individual controlled-substance scheduling, pesticide MRLs outside cannabis, broad keyword search, or a single analyte lookup without a jurisdiction. The response includes jurisdiction-specific product classes, required testing categories, analyte limits, units, and regulation sections.
search_cannabis_regulationsSearch cannabis and controlled-substance regulatory datasets by keyword. Use when the user needs broad discovery across US state testing limits, Health Canada rules, UN scheduling, EU precursors, or EMCDDA/EUDA novel psychoactive substances before selecting a precise compliance or scheduling tool. Do not use for known state testing lookups, exact controlled-substance status checks, or product-class compliance summaries when structured parameters are available. The response includes cross-source matches with dataset labels, jurisdictions, substance or analyte names, product classes, snippets, and regulatory references.
