Unity Execute Menu Item

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

With no annotations, the description must fully disclose behavior but only states the basic action. It does not explain what happens if the menu path is invalid, whether the operation is synchronous, or what the return value indicates. The timeout parameter suggests possible blocking, but this is not explicitly stated.

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 a single, well-structured sentence that immediately conveys the tool's purpose. There is no redundant information or unnecessary detail, achieving maximum conciseness.

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 tool with two parameters and no output schema, the description adequately covers what the tool does. However, it lacks details on error handling, success/failure feedback, or behavioral constraints beyond the timeout. The description is minimally complete but not thorough.

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 100%, so the baseline is 3. The description adds no new meaning beyond the schema's explanations: it repeats 'path' and 'timeout' without additional context or usage examples. The example paths are helpful but already implied by schema.

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', the resource 'Unity Editor menu item', and the method 'by its path'. The example 'File/Save', 'Assets/Refresh' makes it concrete. It is distinct from sibling tools which target game objects, components, or other engine-specific operations.

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 guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, typical use cases, or situations where other tools should be preferred. For instance, it does not advise that menu items not covered by specific tool APIs can be triggered here.

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