Jabbertoon cartoon studio

Read Jabbertoon's guide for writing a cartoon

get_guide
Read-only

Call this first, except for make_cartoon. One topic of Jabbertoon's guide as Markdown (under 20,000 characters): start (what it makes, the order of calls, every other topic), cartoon (the JSON program), text (a cartoon as screenplay text), song (the editor's film file: lines, moves, shots, choreography, words on the picture), build (the 3D builder), export (STL, 3MF, glTF, SVG, Minecraft), minecraft (seven houses to start from, and a build taken into Minecraft), world (a 3D world built from inside, as in Minecraft), game, motion (movement written as words, jabbertoon.com/motion/). x and y are shares of the stage (0 to 1, ground 0.92); times are seconds. Example: {"topic": "cartoon"}.

TDQS

A4.6/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds useful behavioral context: Markdown output format, a 20,000-character limit, default topic behavior, and an example. It does not cover error cases, but for a static read-only guide tool that is a minor gap.

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 call-first instruction is front-loaded and most content is information-rich. However, the topic list is a long run-on sentence with dense parentheticals, and some domain details such as x/y and timing conventions are only loosely relevant to invoking this specific tool.

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?

With one optional parameter, no output schema, and full schema coverage, the description supplies the missing return-format details, size cap, default behavior, topic overview, and example. It gives an agent enough to invoke the tool correctly.

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 schema already documents the optional topic enum and default. The description adds meaning for many enum values and explains stage coordinate and timing conventions, though it does not individually explain every one of the 27 topics.

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: retrieves one topic of Jabbertoon's guide as Markdown. It also distinguishes itself from make_cartoon with an explicit call-first exception.

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?

The description explicitly says 'Call this first, except for make_cartoon' and notes that omitting topic defaults to start. This gives clear invocation order, an exception, and a default.

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