unity_setup_expression_parameters

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

No annotations are provided, so the description carries the full burden. It states the tool generates a file but does not disclose potential side effects (e.g., overwriting existing files), permission requirements, or error handling for malformed JSON. Minimal behavioral context.

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 relatively concise with a clear structure: one-line summary followed by parameter list and example JSON. However, the example takes up space and could be more compact.

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 that there is an output schema (not shown) and 3 parameters with no descriptions, the description should provide more context. It does not explain the format or purpose of the output .asset file, nor how the JSON blueprint maps to VRC parameters. Feels incomplete for a file generation tool.

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 add meaning. It lists parameters with a JSON format example for parameters_json, which adds value by showing structure and allowed valueTypes. However, it does not explain the meaning of each field beyond the example, and output_path default is missing.

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?

Clearly states the action: generate VRCExpressionParameters .asset file from JSON blueprint. The verb 'Generate' and resource 'VRCExpressionParameters .asset file' are specific, and the description distinguishes it from sibling tools like unity_setup_expression_menu by focusing on parameters.

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?

No explicit guidance on when to use this tool versus alternatives (e.g., unity_setup_expression_menu). The description does not mention prerequisites, conditions, or exclusions, leaving the agent to infer usage context.

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