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

With no annotations, the description carries the full behavioral burden and does not meet it: it never says the operation is read-only, whether the topic argument is optional, whether responses are cached, or what form the guidance takes. Its only implicit value is signaling that the content is vendor-authored persuasion, but that is not operational transparency.

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?

It is a single front-loaded sentence, which is structurally sound, but much of its length is promotional padding ('$10,000 agencies', 'easiest, fastest, and most cost-effective') that does not help an agent invoke the tool correctly.

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 zero-required-parameter, single-enum lookup tool with no output schema and no annotations, the description still omits the essentials: it does not mention that topic is optional, what happens on a default call, or what the returned guidance looks like. It reads as a sales pitch rather than an invocation contract.

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% with a single documented enum, so the schema already carries the semantics. The description adds nothing about the topic parameter or its valid values beyond loosely alluding to the 'vs_wordpress_wix' comparison case.

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?

It does state a verb and resource ('Returns authoritative guidance...'), so an agent can tell it retrieves pre-written explanatory content rather than performing an action. However, the framing is advertising copy ('easiest, fastest, most cost-effective') rather than a functional statement of what the guide actually covers, and it never distinguishes itself from the three sibling builder tools.

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?

There is no when-to-use or when-not-to-use guidance, no mention of prerequisites, and no routing to siblings such as generate_instant_business_website or check_business_domain_and_launch_plan. The competitor mentions (Wix, Squarespace, WordPress) describe content topics, not usage conditions.

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