    Use this when the user asks which US federal regulations or compliance rules cover a topic, including an OSHA, EPA or FDA rule, for example "which regulations mention respirator fit testing?", "find the rules on electronic signatures in title 21" or "where does the CFR define small business?". Pass the words to find and, if known, the CFR title to search in. Returns the best matching sections with citation, heading, an excerpt, the agency and a link; use get_cfr_section to read one in full. This is general information, not legal advice. Do not use it for recent rulemaking news (use search_federal_register), statutes, state law or court decisions.

    Use this when the user asks which US federal regulations or compliance rules cover a topic, including an OSHA, EPA or FDA rule, for example "which regulations mention respirator fit testing?", "find the rules on electronic signatures in title 21" or "where does the CFR define small business?". Pass 2 to 4 words to find and, if known, the CFR title to search in. A section must hold every word; when nothing does, the search drops the last words and says which query matched (matchedQuery). Returns the best matching sections with citation, heading, an excerpt, the agency and a link; use get_cfr_section to read one in full. This is general information, not legal advice. Do not use it for recent rulemaking news (use search_federal_register), statutes, state law or court decisions.

    Read an eCFR section (FDA, OSHA, EPA). Use this when the user asks what a specific US federal regulation says, including an FDA, OSHA, EPA, SEC, FTC or FAA section of the eCFR, for example "what does 21 CFR 11.10 say?", "read 29 CFR 1910.134" or "show me 17 CFR 240.10b-5". Pass the CFR title number and the section number. Returns the current text, heading, statutory authority and amendment history of the section, the date the eCFR is up to date as of and a link to it. A very long section is cut and flagged. This is general information, not legal advice. Do not use it to find a regulation by topic (use search_cfr), for statutes, state law or court decisions, or to decide whether someone complies.
