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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully carried by structured data. The description adds nothing beyond the path — no note on pagination, filtering scope, or what the config list contains. With the burden lifted by annotations, this is only mildly deficient rather than harmful.

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?

Very short, but not efficient: the endpoint line is duplicated verbatim and the operation ID is a machine identifier with no decision value for an agent. Front-loading is absent because there is essentially no substance to front-load.

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 read tool with two opaque free-form parameters, no output schema, and no documented response shape, the description should explain what the configs are and how to narrow them. Instead it defers entirely to describe_operation, leaving the agent unable to call this correctly without a second round trip.

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 both parameters (a free-form 'query' object with additionalProperties and an empty 'params' object) are undocumented. The description offers no field names, no accepted filter keys, and no format hints, so an agent cannot construct a query from it. Its one useful contribution is pointing at describe_operation as the source for the native request schema, which is a genuine but partial mitigation.

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 is a verbatim echo of the title and the raw HTTP path, repeated twice. It identifies the resource (payment-portal payout configs) only implicitly through the URL slug, with no plain-language statement of what the operation returns or why an agent would call it. It is closer to tautology than to a stated purpose, though the path does disambiguate it from other payment-portal siblings.

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 guidance and no mention of alternatives such as get_payment_portal_stripe_config or get_leases_by_id_payout_config, which cover adjacent concepts. The only routing hint is 'describe_operation provides native request schemas', which tells the agent about a companion tool, not about when this tool itself applies.

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