## Tools (4)

- `find_competitions`: Upcoming BJJ and grappling competitions from an aggregated public calendar: BJJ Square collects the dates organizers publish on their own public listings (IBJJF, AJP, Smoothcomp, national federations and others). Search by country and date range. Returns at most 10 per call, each with the official organizer page (the source to register and to confirm details), plus the BJJ Square calendar page for the full list.
- `find_gyms`: Find Brazilian jiu-jitsu and grappling gyms by city, by country, or near a point. Give at least one of: city, country, or lat+lng. Returns at most 25 gyms per call (no pagination: narrow the area for more specific results). Each gym has a link to its public page on bjjsquare.com, where contacts and full details are shown. Use get_gym with the slug for the class schedule and what the gym offers.
- `get_gym`: Public details of one gym by its slug (from find_gyms): address, website, affiliation, what it offers, class schedule when the gym has published one, and when the schedule was last updated. Only known facts are returned: a missing field means unknown, not "no". Phone and email are on the gym page linked in the result.
- `list_places`: Countries covered by BJJ Square with gym counts, or, with a country code, the cities of that country with gym counts (largest 200). Use it to check coverage before find_gyms.
