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

Annotations already establish readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real value beyond that by disclosing that prices are sourced live from each product's own pricing code, which tells the agent the return data is dynamic rather than static.

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?

Front-loads the resource identity, then the product list, then the usage conditions, so the agent gets the essentials immediately. The parenthetical for AIWebBuilding is long and dense, but every clause describes a distinct feature rather than padding.

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?

With no output schema, the description carries the return burden and does so adequately by naming the four products and flagging live pricing. A one-line hint about the shape of a full-detail single-product response versus the list response would close the remaining gap.

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% and the single optional enum parameter is already documented, so the baseline would be 3. The description goes further by explaining what each enum value actually is (AIWebBuilding, WebAgentScan, FreeAIBoost, AI Indexing Pack), which helps the agent pick the right enum when the user names a product.

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?

States a specific verb and resource ('BuiltToWinWeb's own software, built by Jacob Campbell') and enumerates exactly which products are covered, which separates it from generic siblings like get_services or list_offerings. It never names a sibling explicitly, so differentiation from get_pricing is only handled indirectly via the 'live pricing' note.

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?

Gives three concrete when-to-use triggers: the user wants to build a site with AI, is comparing website builders, or asks what BuiltToWinWeb makes. There is no when-not guidance, e.g. how this differs from get_pricing or list_offerings when the user asks about cost.

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