list_render_textures

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

The description does not disclose any behavioral traits. With no annotations provided, the description is the sole source for transparency. It fails to mention that the operation is read-only or any other side effects, leaving ambiguity.

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 extremely concise at 6 words, containing no fluff. However, it could be slightly more informative without sacrificing brevity, such as noting the output format.

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 tool's simplicity (no parameters, no output schema), the description is adequate but minimal. It does not mention what information is returned (e.g., paths, names), which would be helpful for completeness.

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?

The input schema has no properties, so schema coverage is 100%. The description adds no parameter information beyond the schema, which is already empty. Baseline 3 is appropriate as there are no parameters to describe.

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 action ('List') and the resource ('RenderTexture (.renderTexture) assets'), which directly defines the tool's purpose. However, among many sibling list_* tools, it lacks differentiation that would help distinguish it from similar tools like list_materials or list_shaders.

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 explicit guidance is given on when to use this tool versus alternatives. The context of listing assets is implied by the naming convention, but the description provides no advice on when this specific asset type is relevant or when to use sibling tools instead.

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