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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It fails to mention any behavioral traits such as whether the tool modifies existing elements, requires authentication, has side effects, or returns any data. For a tool with 6 parameters including nested objects, this is a critical gap.

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 short (one phrase) but at the expense of clarity. It is under-specified rather than concise; every word should earn its place, and here they fail to convey essential information. The structure is not front-loaded with key details.

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 complexity (6 parameters, nested objects, enums, no output schema), the description is entirely inadequate. It does not explain the tool's purpose, behavior, or return values. The agent cannot reliably use this tool based on the description alone.

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 67% (4 of 6 parameters have descriptions), which is moderate. However, the tool description adds no information about parameters beyond what is already in the schema. It does not clarify the meaning of parameters like 'position' (nested object) or 'lightType' beyond the enum names.

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 '3D光照动画' is a vague phrase that restates the tool name without a clear verb or resource. It indicates the domain (3D lighting animation) but does not specify what action the tool performs (e.g., create, apply, control). Among sibling tools like 'transform_3d_animation' and 'camera_3d_animation', there is no differentiation.

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 no guidance on when to use this tool versus alternatives. No context, prerequisites, or exclusions are mentioned. The agent receives no help in deciding between this and similar 3D animation tools.

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