execute_blender_code

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

No annotations are provided, so the description must disclose behavioral traits. It mentions executing arbitrary code but does not disclose potential side effects (e.g., crashing Blender, modifying scene permanently), security implications, or return values. The step-by-step advice is a usage tip, not a behavioral disclosure.

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 only two sentences, concise and front-loaded. However, it could be slightly more structured by separating the purpose from the guidance. It earns high marks for brevity without missing essential elements.

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 has one parameter and no output schema, the description provides the core purpose. However, it lacks information on error recovery, return type, or how the code interacts with Blender state. The step-by-step advice partially offsets this by suggesting safe usage patterns.

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 coverage is 0%, so the description must compensate. It only rephrases the parameter name ('code: The Python code to execute') without adding format, length, or constraint details. No examples or additional context are given.

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 verb 'execute' and the resource 'arbitrary Python code in Blender'. It distinguishes this tool from all sibling tools, which are focused on downloading, generating, or querying assets, none of which involve arbitrary code execution.

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 usage for running Python code in Blender but provides no explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. The step-by-step hint is procedural but not a replacement for when-to-use context.

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