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

No annotations are provided, so the description must bear the full burden. It accurately states that the tool creates an empty asset and requires plugin activation, and that further editing is needed. It does not disclose potential side effects like overwriting existing assets, but given the non-destructive nature (creating a new asset), this is acceptable.

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 concise with two sentences. The first sentence front-loads the main purpose and prerequisite. The second sentence adds necessary context about subsequent steps. No unnecessary words.

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 simplicity (2 parameters, no output schema, no annotations), the description should still cover what the tool returns (e.g., success status, asset path) and potential errors. It only mentions the creation and requirement, leaving the agent uncertain about the outcome.

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%, meaning the description does not explain the parameters. The input schema only provides names and defaults (name: 'MS_Source', package_path: '/Game/Audio') without any additional meaning. The description fails to add value, leaving the agent to infer parameter roles from the name alone.

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 'crea' (creates) and the resource 'asset MetaSound Source vuoto' (empty MetaSound Source asset). It also specifies the prerequisite active MetaSound plugin. This is specific and distinguishes from sibling tools, which do not create MetaSound assets.

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 mentions a prerequisite (active MetaSound plugin) and notes that the graph must be populated later, implying after creation. However, it does not explicitly state when to use this tool versus alternatives, nor does it provide exclusions. The guidance is implied but not explicit.

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