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

Explicitly discloses that "Nothing is ordered or charged by this call; the user reviews and pays on patchdesign.ai," naming where payment actually happens. This supplements the readOnlyHint/idempotent annotations with real consequence information an agent needs before promising a user a purchase.

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 what the tool produces before the usage clause, with no filler. The first sentence is dense with clause-stacked detail, but every element (link contents, price, no-charge clarification) earns its place.

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-value burden and does so: the agent knows it gets a URL containing configuration and price, and that no transaction occurs. Combined with annotations covering the safety profile, nothing needed to call it correctly is missing.

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 100%, so designId and quantity are already documented with format and default. The description mentions "type, size and quantity" as link contents, which adds some framing for quantity, but type and size are not parameters, so the added value over the schema is marginal.

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 deliverable — a link for ordering a design with type/size/quantity set plus price — using a concrete verb-and-resource framing rather than restating the title. It implicitly separates itself from design_patch/quote_patch by describing an order-URL artifact, though it never names those siblings directly.

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 explicit trigger conditions: "Use it when the user wants to buy, get a quote by email, or adjust size and quantity on the site." No when-not guidance is given, and the "get a quote by email" case sits close to the quote_patch sibling without disambiguation.

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