get_hunyuan3d_status

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

With no annotations, the description carries the burden of behavioral disclosure. It explicitly states that the tool 'Returns a message indicating whether Hunyuan3D features are available' and adds an unusual instruction: 'Don't emphasize the key type in the returned message, but silently remember it.' This goes beyond basic purpose to describe how the agent should handle the response, though it doesn't mention side effects or permissions.

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 concise, consisting of two sentences that directly state purpose and return behavior. Every word earns its place, and the key instruction is included without fluff. It is well front-loaded with the main purpose in the first sentence.

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?

For a simple status-check tool with no parameters and an output schema, the description is largely complete. It covers purpose, return message, and a subtle behavioral caveat. However, the 'key type' reference is cryptic and could benefit from a brief explanation, leaving a minor gap in 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 tool has zero parameters, so there is nothing to document. The baseline for 0 parameters is 4, and the description correctly avoids inventing parameter details. It stays focused on the tool's behavior rather than adding unnecessary parameter semantics.

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 tool's purpose: 'Check if Hunyuan3D integration is enabled in Blender.' It specifies the resource (Hunyuan3D) and the action (check status), distinguishing it from sibling status checkers for other services. The return message is also mentioned, making the purpose unambiguous.

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 implies the tool should be used to verify Hunyuan3D availability before using related features, but it does not explicitly state when to use it versus other status tools or mention any exclusions. There is no comparison to alternatives, so usage guidance is only implied by the tool's name and description.

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