Tools as reported by the server

• search_legislation
  Search FULL BILL TEXT -- not just known-bill-number lookup. `q` is matched against titles, descriptions, AND ingested document text via Postgres websearch_to_tsquery (supports "quoted phrases", OR, and -exclusion, same syntax as a search engine), with a fuzzy pg_trgm title-similarity fallback when t
• get_bill_record
  Fetch the full record for one bill: metadata, sponsors, subjects, actions, versions, and vote-event summaries. Look up by canonical bill_id (UUID), or by jurisdiction + identifier (+ optional session to disambiguate). For a human bill number like HB 123, use jurisdiction="NC", identifier="HB 123"; b
• compare_bill_versions
  Deterministic diff (unified + structured) between two versions of a bill's extracted text. Defaults to earliest vs. latest texted version if version ids are omitted. Errors if fewer than 2 versions have extracted text. Result is labeled 'derived' (computed by Bill Commons, not an official document).
• find_similar_bills
  Find bills with similar titles via deterministic trigram similarity, across jurisdictions. Labeled 'derived' -- not an official cross-reference or companion-bill designation.
• get_vote_details
  Fetch vote event(s) with member-level (yes/no/other/absent) vote records. Provide vote_event_id for one vote, or bill_id for all recorded votes on that bill.
• trace_legislative_history
  Full chronological legislative history for a bill: merged timeline of actions, version publications, and votes, plus related-bill links.
• build_legislative_evidence_packet
  Compile a citation-ready evidence packet for a bill: full official record, legislative history timeline, votes with member-level detail, and hearings -- each explicitly labeled official vs. derived with source URLs. Returns a `how_to_cite` block with a one-line `cite_as` sentence, a human `permalink
• get_jurisdiction_coverage
  Return the jurisdiction_coverage state-machine status for one state (abbreviation or name), or the full stored coverage matrix if state is omitted. Public-registry and unlisted row counts are explicit. Includes bounded retained official-source observation health and evidence links. Coverage status m
• get_active_sessions
  List legislative sessions currently flagged active, optionally filtered by jurisdiction (two-letter state code or name).
• list_topics
  List Bill Commons' curated cross-state topic trackers (e.g. artificial intelligence, youth online safety, platform accountability, cybersecurity, cryptocurrency, data privacy, local government & preemption) -- the entry point for "what subjects does Bill Commons track across all 50 states + DC" and
