create_uv_map

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

With no annotations, the description alone must disclose safety and side effects. It only says 'Add', implying a mutation, but does not state whether this creates a new UV layer, overwrites existing ones, or requires specific mesh conditions. This is a significant gap for a mutating tool.

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, clean sentence with no redundant wording. It front-loads the verb and object, making it immediately scannable. Every word earns its place, though it lacks detail covered in other dimensions.

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?

The tool has only two simple parameters and an output schema, but the description is too sparse for a mutating operation. It does not mention interactions with existing UV maps, object requirements, or the nature of the created UV map, leaving the agent with insufficient context for reliable invocation.

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%, and the description adds no information about the parameters. 'object' is implied by the phrase 'mesh object', but 'name' is entirely unexplained, leaving its purpose and default behavior unclear.

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 uses a specific verb ('Add') and identifies the resource ('UV map') and target ('mesh object'), making the primary function clear. It is implicitly distinct from sibling tools like get_uv_maps and smart_uv_project, though it does not explicitly differentiate.

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 offers no guidance on when to use this tool versus alternatives (e.g., smart_uv_project) or any prerequisites. There is no context provided beyond the single action statement.

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