create_map

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

With no annotations, the description bears the full burden for behavioral disclosure. It explains the optional tile generation and the V2 generator behavior, but omits important details such as whether the map is saved to the project, the return value (e.g., map ID), prerequisites (e.g., tileset must exist), or side effects.

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 two sentences long, which is generally concise. However, the first sentence mentions optional tile generation, and the second elaborates on the same point, causing slight redundancy. Still, it is mostly efficient.

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?

Given the absence of an output schema and the presence of 8 parameters, the description covers the core functionality but fails to explain what happens when no theme is provided (e.g., empty map), what the tool returns, and how it relates to other map creation tools in the sibling list.

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 100%, so parameters are already documented. The description adds no new parameter-specific information beyond what the schema provides, as the mention of tilesetId and theme together is already reflected in the schema's theme enum description.

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 a new map with dimensions and properties, and optionally generates a tile layout by theme. It mentions the enhanced V2 generator, which helps distinguish from other map tools like generate_map_batch and generate_map_v3, but could be more explicit about the differences.

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 provides usage context by noting that the enhanced generator is used when a tilesetId is provided with a theme. However, it does not give explicit guidance on when to use this tool versus alternative map creation tools (e.g., generate_map_v3, fill_map_layer) or when not to use it.

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