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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is covered. The description adds nothing beyond that — no note on what a supplemental-rent period represents, whether results are scoped to an active lease version, ordering, or response shape.

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 first two sentences are identical duplicates, and the third is internal metadata (operation ID) plus a pointer to another tool. There is almost no content, yet it is still padded by repetition rather than front-loading useful information.

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?

No output schema exists, so the description should say what a list of supplemental-rent periods contains and how the nested path (lease → supplemental-rent → periods) resolves. With two undocumented path params and no return-value guidance, an agent cannot confidently distinguish this call from neighboring period/schedule endpoints.

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% across both required path parameters, so the description must compensate. The path template at least shows leaseId = lease and id = supplemental-rent record, but there is no explanation of what those identifiers resolve to or what the free-form 'query' object accepts.

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 the endpoint path repeated verbatim twice, which is already the title and largely restates the tool name. An agent can infer 'GET the periods of a supplemental-rent record for a lease' from the path, but the description itself adds no articulation of what a 'period' is or how it differs from the many sibling supplemental_rent endpoints.

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?

No when-to-use / when-not-to-use guidance and no comparison against the ~12 sibling supplemental_rent tools. The only routing hint is 'describe_operation provides native request schemas', which points at a helper tool rather than describing appropriate caller scenarios.

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