execute_blender_code

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

No annotations provided, so the description must disclose behavioral traits. It only states that arbitrary code is executed, without mentioning side effects, security implications, potential crashes, or whether the code runs in a sandbox. This is insufficient for a potentially destructive tool.

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 very short, using two sentences. The first defines the tool, the second gives advice. It could be considered concise, but it might benefit from slightly more detail without being verbose.

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 (executing arbitrary code), the description lacks essential details: no mention of error handling, return behavior, Blender environment specifics, or limitations. This makes it dangerously incomplete for an agent to use safely.

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 schema has 0% coverage (description does not repeat schema). The parameter description 'The Python code to execute' merely restates the schema's type and name, adding no meaningful semantics about formatting, constraints, or execution context.

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 'Execute arbitrary Python code in Blender', which is a specific verb-resource pair. It distinguishes itself from sibling tools that perform specific Blender operations, as this is a generic code execution tool.

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 advises breaking code into smaller chunks and doing it step-by-step, implying it should be used for complex scripting. However, it does not explicitly state when to use or not use this tool versus alternatives, leaving the context implied.

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