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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that the tool generates JSON-LD via AI but does not mention whether it returns the generated markup, modifies the page, requires authentication, or any side effects. The absence of any behavioral traits beyond the core action is a significant gap.

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 sentence with no wasted words, making it front-loaded and efficient. However, it is overly terse and lacks essential details, so while it is concise, it is under-specified. It earns a middle score: not verbose, but not adequately informative.

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 lack of annotations and output schema, the description should cover what the tool outputs, when to use it, and parameter semantics. It only states the basic purpose, leaving out return value format, expected usage context, and parameter behavior. The tool is simple, but the description is incomplete for an agent to invoke it correctly.

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 adds no meaning to the parameters. It does not explain that 'url' is the target page or that 'type' can specify the schema type. With two undocumented parameters, the description entirely fails to compensate for the lack of schema coverage.

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 uses a specific verb ('Generate') and resource ('JSON-LD structured data') for a page using AI. It clearly distinguishes this generation tool from sibling tools like seo_check_schema, which checks existing schema rather than creating it. The phrase 'using AI' adds a clear method indicator.

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 provides no guidance on when to use this tool versus alternatives. It does not mention that seo_check_schema should be used for validation, nor does it indicate context like 'when you need to add structured data to a page.' There is no exclusions or alternative tool references.

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