execute_hscript

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It does not mention any side effects, such as whether the command can modify the scene, require authentication, or how errors are handled. The description only states that it executes a command, offering minimal insight into its behavior.

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 extremely concise, with only two short sentences. It is front-loaded with the core purpose and provides a parameter description. There is no fluff, but perhaps it is too brief to be helpful.

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?

Despite the tool having only one parameter and no output schema, the description lacks essential context. There is no mention of use cases, potential risks, or examples, making it hard for an agent to know how to use it effectively, especially given the large number of sibling tools with overlapping capabilities.

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 description coverage is 0%, and the description only provides a one-line summary of the 'command' parameter ('HScript command string to execute.'). This duplicates the schema's property name and type, adding no extra meaning about expected format, syntax, or examples. The agent receives no guidance on how to construct a valid HScript command.

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 states it executes an HScript command in Houdini, which is a clear verb-resource pair. However, it does not differentiate from sibling tools like execute_python or evaluate_expression, which may be used for similar scripting purposes. The purpose is clear but not distinct enough.

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 lacks any guidance on when to use this tool versus alternatives like execute_python or evaluate_expression. There is no mention of typical use cases or reasons to prefer HScript over other scripting options, leaving the agent to infer the context.

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