A3.5/5.0
Behavior2/5

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It labels the operation as 'Get' (implying a non-destructive read), but it does not mention behavior if the object does not exist, what coordinate space the values are returned in, or whether it reflects the current scene state. These are meaningful gaps for a Blender mutation-heavy environment.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded with the verb and resource, and every word contributes. There is no filler, repetition, or redundantly restating the title or inputs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter getter, the description gives the purpose, but the surrounding ecosystem (27 Blender tools including creating/deleting/translating/rotating objects) makes it valuable to say 'scene objects ' or point to a listing tool. Since an output schema is present, return-value documentation isn't required, so a 3 is appropriate: adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides only a bare string parameter 'name', so the description's 'by name' adds minimal semantics by tying the parameter to the object identifier. It still does not explain name format, uniqueness, or how to discover valid names, which is needed when schema coverage is 0%.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Get') and precisely names the resource ('Blender object') plus the exact data fields ('position, rotation, and scale'), and shows the input key ('by name'). This lets an agent distinguish it from siblings like blender_object_get_hierarchy or blender_scene_list_objects with no extra effort.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The intended use is clearly implied: call this tool when you need an object's transform values, using the object's name as input. However, there is no explicit 'when to use vs alternatives' or mention of how to obtain the required name (e.g., using blender_scene_list_objects), leaving some guidance gaps.

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