create_world

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

The description discloses that the world is deterministic and empty, and mentions the color range 0-15, which adds some behavioral context. However, with no annotations, it fails to mention side effects such as overwriting an existing world, required setup, or the meaning of the background parameter, leaving significant gaps.

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

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

The description is a single, front-loaded sentence that efficiently conveys the core purpose without unnecessary fluff. While it is concise and well-structured, its brevity means it lacks important details, but the structure itself is good.

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

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

Even with an output schema present, the description is too sparse for a tool with four parameters and no annotations. It does not explain parameter usage, side effects, or prerequisites, making it incomplete for an AI agent to invoke correctly.

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

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

Schema description coverage is 0%, so the description must compensate by explaining parameters, but it does not. It only mentions raw ARC colors 0-15, which is not directly mapped to any specific parameter, leaving width, height, debug, and background unexplained.

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

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

The description clearly states the tool creates an empty deterministic world using ARC colors 0-15, with a specific verb and resource. This distinguishes it from sibling tools like load_static_map, which loads a static map rather than creating an empty world.

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

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

The description implies this tool is used to initialize a new world by stating it creates an empty world, but it provides no explicit guidance on when to use it versus alternatives or any prerequisites. The usage context is implied rather than stated.

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