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

No annotations are provided, so the description carries full burden. It describes the return value but omits behavioral traits such as read-only nature, authentication requirements, rate limits, or error cases. For a read endpoint, this is a significant gap.

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 a single dense sentence that lists many return fields. While not verbose, it could be restructured (e.g., bullet points) for improved readability. It is not wasteful but could be more scannable.

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?

Given a single parameter and no output schema, the description provides a fairly comprehensive list of what is returned. It covers major sections of the response, though details like field types or nested structures are not specified. Overall, it is sufficient for an agent to understand the tool's purpose and output.

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% with a single parameter described. The description adds marginal value by clarifying the id comes from search_rentals results and providing an example, but the schema already explains the parameter adequately.

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 clearly states the tool fetches full details for a single rental listing by id, and enumerates the returned data (description, amenities, pricing history, building info, transit, schools, media). It distinguishes itself from siblings like search_rentals (broad search) and list_amenities/list_areas (categorical listings).

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?

The description instructs to use the `id` from search_rentals results, implying a prerequisite. However, it does not explicitly state when not to use this tool or mention alternatives beyond the sibling context.

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