    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Builds anything (a character, an animal, a car, a house) in Jabbertoon's 3D builder from steps, as its buttons do: spine, grow, bone (a skeleton, a bone at a time), add a ready part (leg, arm, head, wing, wheel, hat ...), set, copy, remove, look. Checks every step, says what was made (its parts and size) and gives a jabbertoon.com/editor/ link that opens it in the Studio, to change and use in a cartoon, world or game. Over MCP the answer also shows a picture of it from four sides. Steps that start {"op": "new", "kind": "move"} make a move from keys, {"op": "new", "kind": "world"} a world (a level is played to check it), and kind "game" a game seen from the side, from above or in space, or "trench", "space", "surface" or "sky" a game with depth to fly, "walk" a place to walk at real size (played on foot: told what cannot be reached). A refused step says where, why and how to fix it. export_link opens Export, free: STL/3MF to 3D print, glTF (Blender, Unity, Godot), SVG, Minecraft .schem. The steps: get_guide {"topic": "build"}, a game's {"topic": "game"}.

      annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "get_guide" says "get": a word for reading.

      What this check looks for
    Description, as the server wrote it
    Call this first. Returns one topic of Jabbertoon's guide as Markdown (under 20,000 characters): start (what it makes and the order of calls), cartoon (the JSON program: cast, scenes, lines, moves), text (the same cartoon as screenplay text), moves, characters, looks, voices, places, errors, limits, build (the 3D builder's steps), export (a build as a 3D printer's STL or 3MF, glTF for Blender, SVG blueprints, Minecraft), world (a world of blocks), walk (a place to walk), game (a game's steps), song (the editor's own file: characters, lines, moves, shots, a song), market, controls (pills, actions). Units everywhere: x and y are shares of the stage (0 to 1, the ground at 0.92), times are seconds. Example: {"topic": "cartoon"}.

    Why it is in this group

    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    Description, as the server wrote it
    Tells the people who make Jabbertoon something is wrong: a wrong answer, a check that refused a good cartoon or passed a bad one, a move that looks wrong, a link that does not open, wrong docs, something missing, or a step that was hard to get right (kind hard_step, with hard_because: optional, never needed to go on). Unlike the other tools, it keeps what you send: the report (kind, tool, code, where, item, note, hard_because) is saved for a person to read. Never put the cartoon, a name, an address or anything about the person you help in it. Example: {"kind": "validator_wrong", "tool": "validate", "code": "op_unknown", "note": "say was refused in a cartoon"}.

    Description, as the server wrote it
    Returns one ready-made move: its block program as JSON, the same program as screenplay text, its length in seconds, what it works on, its settings with units, its page and links. Name it by id (c4c:beh:wave_hello), short name (wave_hello) or page slug. To write your own move, start from one, change it, then validate it. Example: {"move": "wave_hello"}.

    Description, as the server wrote it
    Lists the cast in 3D: the six people (bob, ria, sunny, sam, lee, rose) and the animals (dog, cat, fox, horse, gull, and bear2, fox2, rabbit2, raccoon2, cat2 on two legs), each with the designed entry a cast entry gives it and a voice; the voices a line can use; and cartoon_example, a whole talking cartoon to copy.

    Description, as the server wrote it
    Lists the six art styles a character can be drawn in (flat, outlined, soft, storybook, bold, crayon), each with its page and a studio link, and the three body shapes (classic, big head, tall).

A does block plays one: {"op": "does", "who": "dog", "behaviour": "c4c:beh:wave_hello"}. q keeps the moves whose words match or that do what a word means (dance finds Groove, scared finds Cower).

    Why it is in this group

    • The name "validate" says "validate": a word for reading.
    Description, as the server wrote it
    Checks a cartoon, with the studio's own checks, before anyone sees it. Give one of cartoon, program, pack, character or file. Returns errors (it will not play as written: also a character or background the site lacks) and warnings, each {code, where, says, fix, url}, with did_you_mean and an RFC 6902 patch when certain; issues a viewer would see (off stage, overlapping, an empty stage, a line cut off) with a summary of who is where and says what when (seconds; x as a share of the stage); and, when ok, the canonical program and a link. repair: true also returns the program with every certain patch applied. Nothing you send is kept. Example: list_characters' cartoon_example.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
