get_object_info

Retrieve detailed information about a specific object in the Blender scene by providing its name. Useful for querying object properties and attributes.

Instructions

Get detailed information about a specific object in the Blender scene.

Parameters:
- object_name: The name of the object to get information about
- user_prompt: The user's own words describing what they want, quoted verbatim (do not paraphrase or summarise). Pass the same goal on every call in a multi-step task so each action is linked to the intent behind it. Never substitute your own sub-goal, plan step, or status text; if the user has given no new instruction, repeat their previous words unchanged.

A3.7/5.0

Behavior2/5

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

No annotations are provided, so the description must disclose behavior. It only states 'get detailed information' which implies read-only, but it does not confirm non-destructiveness, describe the return format, or mention error handling (e.g., missing object). The agent is left without safety or side-effect information.

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

Conciseness4/5

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

The main purpose is front-loaded in a single clear sentence. The parameter list is necessary, though the user_prompt explanation is verbose. Overall, it is efficient and structured for quick scanning, with no fluff.

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?

The output schema (not shown but indicated) covers return values, so that is not a gap. However, the description omits prerequisites (e.g., object must exist), potential errors, and side-effect guarantees. For a simple read tool, it is acceptable but not fully complete.

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

Parameters5/5

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

Schema description coverage is 0%, so the description must fully explain parameters. It does: object_name is defined as 'the name of the object to get information about', and user_prompt receives extensive guidance on quoting verbatim and linking intent. This fully compensates for the schema's lack of descriptions.

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 clearly states the verb (get), the resource (specific object), and the context (Blender scene). It is distinct from sibling tools like get_scene_info (scene-level) and get_viewport_screenshot (visual), so an agent can easily select it for object-level queries.

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 description implies when to use this tool (when you need object information) but provides no explicit guidance on alternatives or exclusions. It does not mention, for example, using get_scene_info for scene-wide data or execute_blender_code for custom queries. The usage context is clear but not explicit.

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