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

Annotations indicate non-readonly, non-idempotent, destructive behavior. The description adds crucial context by stating 'Price: 3 USD' and 'Payment requires explicit wallet authorization,' which is not present in annotations. This discloses cost and payment side effects beyond the structured data.

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?

Two sentences, front-loaded with the core function and output components, followed by a critical cost/payment note. No wasted words or redundancy.

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?

While the description lists output components, it omits details about the return format, handling of result_expires, idempotency_key, and payment_signature parameters. Since there is no output schema, the description should compensate but leaves gaps on how results are delivered and how to manage the payment flow.

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 mentions 'business/service/location inputs' without explaining the purpose or format of individual parameters like tone, description, result_expires, idempotency_key, or payment_signature. The agent gets minimal help on how to fill these fields.

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 it generates a complete SEO-ready local landing page with specific components (title, meta, H1, sections, FAQs, CTA) from business/service/location inputs. This is a specific verb+resource and distinguishes it from sibling tools like homepage_copy or service_page_copy.

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 does not provide any guidance on when to use this tool versus similar page generators, nor does it mention alternatives or exclusions. It only states inputs and output, leaving the agent to infer when it is appropriate compared to siblings like landing_page_copy.

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