Tools: capitolguide_prep overview find_room route_between accessible_route check_access nearby prohibited_items plan_day
capitolguide_prep | Pre-flight readiness check. Run before any other tool. Verifies secrets, KV, DB connectivity, and KB version + freshness. Returns a structured readiness report. params: none |
overview | Operational snapshot for the caller's tenant: KB version + freshness, queue depths (itineraries / draft meetings / active nudges), and the recent tool-invocation tail. Read-only. params: none |
find_room | Find a Capitol office by ROOM CODE (e.g. 'SH-217', '2310 Rayburn', '167 Russell', 'H-232'), by MEMBER NAME (e.g. 'Cornyn', 'Ted Cruz', 'Womack'), or by COMMITTEE ('Senate Judiciary', 'Ways and Means', 'House Armed Services'). A room code returns the decoded location plus who currently holds it; a name returns that member's current office; a committee returns its office / principal hearing room. Me params: query* |
route_between | Turn-by-turn directions between two points in the Capitol complex. Each point can be a room code, a building name, OR a Metro station / landmark (e.g. 'Capitol South Metro' → '2412 Rayburn', 'Union Station' → '517 Hart', or to the 'Supreme Court' / 'Library of Congress'). Returns an ordered step list with mode (walk/tunnel/subway), minutes, and a flag wherever you re-clear security. Set accessible params: from*, to*, accessible |
accessible_route | Step-free / accessible directions between two points in the Capitol complex by mobility profile (wheelchair, limited_mobility, stroller, low_vision). Routes over elevators/ramps only, avoids stairs, and surfaces OCAS accommodation contacts. Use this instead of route_between when step-free matters. params: from*, to*, mobility_profile |
check_access | What access a visitor needs for a zone of the Capitol complex: (visitor_type × zone) → allowed?, credential, escort, lead time, required docs, security entrance, and the granting authority. INFORMS, never grants — final authority is the member office / Capitol Police / Secret Service. Rules are volatile and live-source-stamped. params: visitor_type*, zone* |
nearby | Nearest restroom, exit, and food for a specific point — a room code (floor-specific, e.g. the exact nearest bathroom to SH-217), a building name, or GPS coordinates {lat, lon}. Returns specific named venues ranked by distance. params: location, lat, lon |
prohibited_items | What you cannot bring into an area of the Capitol complex (security screening). zone: 'capitol_cvc' (the Capitol + Visitor Center — strictest, no food/water), 'gallery' (House/Senate galleries — no phones/cameras), or 'office_building' (the 6 office buildings — food & drink allowed). Always returns the universal weapon/hazard bans too. Volatile — live-source-stamped; confirm at visitthecapitol.gov params: zone* |
plan_day | Optimize a multi-meeting Hill day. Give a list of meetings (each a member name or room code, with an optional time like '10:30a'). Returns a sequenced itinerary: batched by chamber side to minimize cross-campus crossings, the route + minutes between each stop, the cross-campus window flagged, 'leave-by' times when meetings are timed, and warnings for connections too tight to make. params: meetings*, accessible |
