list_chapters Read-only

Lists one plate’s chapters (ids and titles) and the lab settings it accepts (ids, ranges, options), for show_model. Use it when the user wants another part of a plate than the one search_models gave, or wants to set the lab.

slugstring, required

The plate id from search_models (e.g. "tides").

langstring

zh (Chinese) or en (English).

list_chapters

read-only

Argument	Type	Description
lang	string	zh (Chinese) or en (English).
slug*	string	The plate id from search_models (e.g. "tides").

search_models

Use this when the user asks how something works or why something happens in physics, engineering, AI, biology and medicine, earth and space science or mathematics, or asks to see or try a mechanism: e.g. “why do we have seasons”, “how does a jet engine work”, “潮汐是怎么形成的”, “Transformer 的注意力是什么”. Searches the interactive 3D models (“plates”) on world.lapla.si: first an index of the questions each plate answers (Chinese and English), then titles and topics. Returns the best plates, each with its slug, the chapter that answers the question and sometimes lab settings, to pass to show_model. Returns no results when no plate covers the question. Not for news, prices, homework calculations, or medical, legal or financial advice.

read-only

Argument	Type	Description
lang	string	Language of the results: zh (Chinese) or en (English). Default: the query’s language.
limit	integer	How many plates to return at most.
query*	string	The user’s question in their own words, in any language (e.g. “why is the sky blue”, “光刻机是怎么工作的”), or a topic (“black hole”, “黑洞”).

    }
  },
  "additionalProperties": false
}

show_model

Shows one interactive 3D model from world.lapla.si in the conversation, opening at the chapter that answers the user’s question; the user can turn it, step through its chapters and try its lab. Use it after search_models with the slug and chapter (and params) it returned, or when the user names a plate. Also returns a short text summary and the plate’s link, for clients that show no UI.

read-only

Argument	Type	Description
lab	boolean	Open the lab panel.
lang	string	zh (Chinese) or en (English).
slug*	string	The plate id from search_models (e.g. "seasons").
params	object	Lab settings by id, from search_models or list_chapters: a number for a slider, an option id for a choice, true/false for a toggle.
chapter	string	The chapter id to open at, from search_models or list_chapters (e.g. "tilt"). Default: the cover.
