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

There are no annotations, so the description carries the burden. It does disclose that the operation creates/updates and adds a valuable warning that the redirect signing secret is returned only once. However, it does not explain what happens to existing fields on update, prerequisites, or error cases, leaving significant behavioral gaps.

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 short and front-loads the main action before adding the one-time-secret warning. The bilingual duplication uses two sentences but remains compact; no filler.

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?

Despite 15 optional-looking parameters and no output schema, the description does not state prerequisites, what the API returns beyond the secret, or how partial updates behave. It is enough to understand the tool's role but not enough to invoke it reliably.

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 only 7%, so the description must compensate for 15 parameters. It groups some fields into broad concepts (shop name, identity, receiving account) but does not map them to actual parameter names and leaves merchant_id, terminal_id, locale, hotline, support_email, and others unexplained.

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 the verb and resource clearly: creates or updates the hosted-checkout payment profile, naming the shop name, identity, and default receiving account. The phrase 'before creating checkout' also separates it from checkout creation, though it does not explicitly name sibling 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?

Explicitly says this happens 'before creating checkout', giving the agent a clear timing/context for when to call it. It does not mention alternatives or exclusions such as using get_payment_profile for reads, but the stated precondition is clear.

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