list_rentals

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

With no annotations, the description carries the full burden. It discloses return format ('Dictionary with rentals list and metadata') and pagination parameters, which is useful. However, it does not explicitly state that the operation is read-only, mention any ordering, or note potential rate limits or errors, leaving some behavioral aspects undisclosed.

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 concise and well-structured: a clear one-line purpose followed by parameter and return documentation. Every sentence provides value, with no fluff or redundancy.

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 simple list tool with an output schema and two optional parameters, the description covers the essential aspects: purpose, parameters, and return type. It is slightly incomplete in not explicitly noting the read-only nature or clarifying whether the list is all rentals or filterable, but overall it is sufficient for basic invocation.

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?

The input schema provides no parameter descriptions, so the description fills this gap by defining limit as 'Maximum number of results' and offset as 'Offset for pagination'. This adds meaningful semantics beyond the bare schema defaults, though it could be more detailed about pagination behavior (e.g., zero-based offset).

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 'List rental properties from Buildium' with a specific verb and resource. It distinguishes itself from sibling tools like list_leases or list_associations by naming the 'rental properties' entity, though it does not explicitly contrast with get_rental.

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 guidance is provided on when to use this tool versus alternatives such as get_rental or list_rental_units. The description only states the basic function without any context or exclusions, leaving the agent to infer usage from the name alone.

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