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

- `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
