SFomo: Bay Area events

Search events

search_events

Read-onlyIdempotent

Search every upcoming Bay Area event by words, dates, price, topic or place: dance, AI, music, arts, food, sports, comedy, exercise, volunteering, dating, business and professional networking. Use it whenever the question has search words, a date range ("this weekend": from/to), free-only, a town or an area; for a day-by-day overview of the next few days with no search words use list_upcoming, for one act by name find_performer. Words in query match the title, venue, performers, organizer or tags at the start of a word, singular or plural, with common synonyms (standup = stand-up, kids = children); by default all of them must match, with match "any" (or | / commas between them) any one does. A word that matches nothing is read as the closest word the events use, and search in the result says how the query was read. Dates are local (America/Los_Angeles), YYYY-MM-DD. Results come earliest first, at most limit; count says how many matched in total, so narrow the search rather than paging. get_city lists valid neighborhood, town, category and topic values. No sign-in; each client gets 30 calls a minute and 2,500 event rows an hour.

Input Schema

Name	Required	Description
`to`	No	Latest date (default: none)
`city`	No	City, e.g. 'San Francisco' or another town in the Bay Area (case-insensitive)
`free`	No	Only free events (a listed free price, or an unpriced listing from a source whose events are free)
`from`	No	Earliest date (default: today)
`near`	No	Events within radius_km of a place: a neighborhood, a town, a venue name, or "lat,lon". Results get distance_km, nearest first within each day. Use this for "near X"; use neighborhood for "in X". Unmapped venues are left out (counted in place.unplaced_events).
`limit`	No	Max results (default 25, max 100)
`match`	No	all (default): every word in query must match; any: at least one word or \|-separated phrase does (results with more matches are no different in order: earliest first); semantic: by meaning ("something romantic", "chill music outdoors"), from an embedding of query
`query`	No	Free text, e.g. 'salsa', 'hackathon', 'street fair'. Separate alternatives with \| or commas ('salsa \| bachata', 'comedy, improv'); keep a phrase together with quotes. A neighborhood or town after 'in'/'near' ('art openings in SoMa') becomes the place filter.
`scope`	No	Geography: one region (sf = SF, peninsula = Peninsula, south_bay = South Bay, east_bay = East Bay, north_bay = North Bay, santa_cruz = Santa Cruz, beyond = Farther), bay_area (sf, peninsula, south_bay, east_bay, north_bay), or any (default)
`topic`	No	Topic (the site's Arts, Food, Learn, Sports tabs: e.g. comedy, film, food_drink, sports, talks, classes, markets, outdoors; business = chamber mixers, referral groups, small-business workshops, trade shows, career fairs; ai = AI events (the site's AI button); tech = developer, data, security, crypto, UX and tech-community events (the Tech button also includes ai and category ai))
`season`	No	Seasonal series tag, e.g. 'techweek27' (only when the site lists one)
`sector`	No	Industry a work event is for (only events with a work topic carry one; general networking has none): e.g. senior_care, healthcare, real_estate, finance_insurance, legal, tech
`audience`	No	Who the event is only for: kids, teens, seniors (older adults: senior-center programs, 55+ groups), or general (none of those). Default: no filter. Caregiver/aging talks for families and professionals are general.
`category`	No	Scored category (the site's AI, Dance, Fun, Gym, Music, Singles, Volunteer tabs)
`radius_km`	No	Distance for near (default 1.5, max 50), or how far neighborhood reaches past its boundary (default 0)
`biz_format`	No	Kind of work event: referral_group (BNI etc.), chamber, mixer, breakfast_lunch, workshop_training, conference_expo, career_fair, ce_credits, pitch_demo, committee_meeting
`neighborhood`	No	Only events in this San Francisco neighborhood (or town): Bayview, Bernal Heights, Castro, Chinatown, Excelsior, FiDi / South Beach, Glen Park, Golden Gate Park, Haight, Hayes Valley, Ingleside / Oceanview, Inner Richmond, Inner Sunset, Japantown, Lakeshore, Lincoln Park, Lone Mountain / USF, Marina, McLaren Park, Mission, Mission Bay, Nob Hill, Noe Valley, North Beach, Outer Mission, Outer Richmond, Pacific Heights, Portola, Potrero Hill, Presidio, Presidio Heights, Russian Hill, Seacliff, SoMa, Sunset / Parkside, Tenderloin, Treasure Island, Twin Peaks, Visitacion Valley, West of Twin Peaks, Western Addition. Sub-neighborhood and common names work too. Add radius_km to also take events within that distance of its centre. Events whose venue isn't mapped can't be placed and are left out; the response's place.unplaced_events counts them.
`changed_since`	No	Only events added or changed (title, date or time, venue, link, price, sold out, status) at or after this moment: YYYY-MM-DD (local) or an ISO date-time. To follow up later, pass the previous result's changes.synced_at; changes.removed then lists events taken down since.

Output Schema

Name	Required	Description
`count`	Yes	Events that matched in total
`place`	No
`shown`	Yes	Events returned (at most limit)
`events`	Yes
`search`	No	How the query was read
`changes`	No	Only with changed_since
`coverage`	No	Coverage and accuracy page
`attribution`	No
`briefing_url`	No	The dated weekly briefing for this week or next (counts plus picks per kind of event, #lane when the filters match one); null further out. Cite it for "what's on this week"
`data_generated`	No	When this city's data was last published

A4.8/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare it a safe read (readOnlyHint, idempotentHint, destructiveHint=false), and the description still adds substantial operational context: prefix/singular-plural/synonym word matching, all-vs-any semantics, a fuzzy fallback whose interpretation is echoed in the result's `search` field, local America/Los_Angeles dates, earliest-first ordering, and rate limits (30 calls/minute, 2,500 rows/hour) with no sign-in. The count-vs-limit guidance ('narrow the search rather than paging') is a non-obvious pagination constraint stated up front.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The essential framing — what it searches, when to use it, which siblings to prefer — is front-loaded in the first two sentences. The remainder is a dense run-on covering matching rules, ordering, paging and rate limits; almost all of it is useful, but the single unbroken block makes it harder to scan than it needs to be.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For an 18-parameter, zero-required search tool with an output schema, the description covers what the schema cannot: matching semantics, timezone, result ordering, how to avoid paging, rate ceilings, and the pointer to get_city for enum values. An agent has everything needed to call it correctly and interpret the count/search fields.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description earns more by explaining the default all-words-must-match behavior, the `|`/comma alternative syntax, and the near-vs-neighborhood distinction for 'near X' vs 'in X'. It slightly duplicates what the `query` and `near` schema descriptions already say, which keeps it off a 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource — 'Search every upcoming Bay Area event' — and immediately enumerates the facets it searches across (words, dates, price, topic, place). It explicitly names the sibling tools it is not: list_upcoming for day-by-day overviews and find_performer for a single act, so an agent can route without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit trigger condition ('whenever the question has search words, a date range, free-only, a town or an area') and names two concrete alternatives with the conditions that select them (list_upcoming, find_performer). It also points to get_city as the source for valid neighborhood, town, category and topic values, closing the value-discovery loop.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
