create_image_texture

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

The annotations indicate readOnlyHint=false and destructiveHint=true, but the description adds no context about side effects such as overwriting existing datablocks or permission requirements. It does not contradict the annotations but provides no additional behavioral insight.

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 sentence with no redundancy, front-loading the core purpose. However, it is under-specified for a tool with four parameters, so it sacrifices completeness for brevity.

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 simplicity of the tool, the description is too thin. It lacks information on parameter ranges, color format, or what 'procedural' means in this context. The presence of an output schema does not compensate for missing usage guidance.

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 does not explain any parameters. Properties like name, color, width, and height are only defined by their names and defaults, leaving the agent to guess their meaning and valid ranges.

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 'Buat datablock gambar prosedural' clearly states a create operation on a procedural image datablock, distinguishing it from sibling 'assign_image_texture' which assigns an existing texture. It uses a specific verb and resource, but does not elaborate on what 'procedural' entails.

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?

No guidance is provided on when to use this tool versus alternatives like 'assign_image_texture' or 'create_material'. There are no prerequisites, exclusions, or contextual hints to help the agent decide when to invoke it.

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