SceneF — California, Florida and Hawaii Movie Showtimes

Suggest a movie night

scenef_plan_movie_night

Read-onlyIdempotent

Suggests 2-4 movie-night options on one board from a window and a taste profile — film + specific showtime + theater + why it fits — plus one wildcard: the highest-ranked film outside the stated genres, or the next film down when no genre is stated. time_after/time_before are hard bounds; genres and formats only tilt the ranking, and when one matches nothing in the window the answer opens with a warning (also in warnings[]) saying so. It books, reserves and saves nothing; each option carries ticket and calendar links for the person to follow. Ranking uses only the stated preferences; no theater or film pays for placement. Read-only: the call itself records nothing. SceneF does not sell, hold or book tickets. Ticket links are https://scenef.com/go/{id} redirects to the theater's own site or the ticket seller it uses (a link to a showtime that is gone lands back on SceneF); whoever follows one, a person or a client, is logged once anonymously (time, the screening with its film and theater, client type, browser family, referring site, link source tag, and whether the showtime was gone; no IP address, cookie or account) and forwarded. Every emitted showtime carries confidence, source tier, reporting sources and verified_at.

Input Schema

TableJSON Schema

Name	Required	Description
`when`	No	When to look: "tonight" (default), "tomorrow", "weekend" (Fri/Sat/Sun of the current week), or a YYYY-MM-DD date.
`region`	No	Which regional board to read: a board id such as "sf", "oahu" or "miami", not a city name ("Honolulu" or "Chicago" is rejected). Omitted means "sf" (San Francisco); it is never inferred from where you are. For a city, ZIP or neighborhood call scenef_resolve_board first; scenef_now with no region lists every id. An unknown region is an error, not a fallback.
`party_size`	No	How many people are going (1-20). It labels the plan; it does not change which shows are picked.
`preferences`	No	Bring-your-own taste profile. Everything here tilts the ranking and degrades gracefully EXCEPT time_after/time_before, which are hard bounds.
`response_format`	No	Output size. "concise" (default) is tight text plus a structured summary. In whats_playing, each film has the total showtime_count, next_showtime, and a showtimes array containing only that next screening; "detailed" adds showtime rows with ids, ticket urls and accuracy metadata, about 200 across the answer. film_details and search_showtimes return the 40 nearest showtimes in "concise" and up to 200 in "detailed". showtime_count is always the total and showtimes_complete says whether the array is all of it; narrow by date or theater for the rest.

Previous value: -"Output size: \"concise\" (default) for tight text lines, \"detailed\" to add ids, per-showtime ticket urls, and extra metadata."New value: +"Output size. \"concise\" (default) is tight text plus a structured summary — on list-shaped tools each film carries showtime_count and next_showtime, but NOT the full showtimes array. \"detailed\" adds the per-showtime rows with ids, ticket urls, and accuracy metadata. Concise measures ~10KB where detailed measures ~69KB, so ask for detailed when you need the rows and scenef_search_showtimes when you need them for one film or theatre."

A4.3/5.0

Behavior5/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, openWorld), yet the description adds substantial non-obvious behavior: it books/reserves/saves nothing, ranking is preference-only with no paid placement, unmatched genres/formats surface a warning in warnings[], and every ticket link is an https://scenef.com/go/{id} redirect that anonymously logs a follow and forwards to the theater. The confidence/source-tier/verified_at metadata disclosure is also beyond anything the schema states.

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

Conciseness3/5

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

The purpose and constraints are front-loaded well, but the body is dense and runs long, with the ticket-link/logging paragraph expanding into tangential detail (client type, browser family, referring site, cookie/IP disclaimers) that is only loosely tied to calling the tool. Several em-dash-joined clauses are run-on and could be tightened without losing meaning.

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?

An output schema exists, so return structure needn't be explained, yet the description still covers what an agent needs: the 2-4 option shape, the wildcard, the warning channel, the no-booking guarantee, ranking ethics, and link behavior. Combined with a fully documented 5-parameter schema, nothing required to call it correctly is missing.

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 description coverage is 100%, so the baseline is 3, but the description adds genuine meaning on top: it explains the wildcard rule (highest-ranked film outside the stated genres, or next film down when no genre is given), reinforces that genres/formats tilt rather than filter, and states that time bounds do not degrade. These clarify how the preferences object actually behaves beyond the per-field text.

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?

Opens with a specific verb+resource+scope: 'Suggests 2-4 movie-night options on one board from a window and a taste profile', then enumerates exactly what each option contains (film, showtime, theater, rationale, wildcard). This is clearly distinct from sibling list/search tools like scenef_now, scenef_whats_playing and scenef_search_showtimes, which return raw listings rather than a curated plan.

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

Usage Guidelines3/5

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

Usage is implied by the purpose and by the hard-vs-soft semantics ('time_after/time_before are hard bounds; genres and formats only tilt the ranking'), which tells the agent when a preference will fail loudly vs degrade. However, there is no explicit when-to-use-this-vs-alternatives guidance against siblings such as search_showtimes or whats_playing, and the routing advice for cities (call scenef_resolve_board first) lives only in the region schema field.

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