get_rental_unit

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only states 'Get', which implies a read operation, but does not mention handling of non-existent IDs, authorization requirements, or any side effects. This adds little beyond the tool name.

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, concise sentence that front-loads the action word 'Get'. Every word is necessary, with no redundancy or 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?

The tool is simple with one parameter and an output schema that likely defines the return shape. The description, while minimal, adequately covers the core purpose. However, the lack of any explicit usage guidance and minimal parameter semantics leave small gaps, making it not perfectly complete.

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 has no description for 'unit_id' (0% coverage). The description's 'by ID' clarifies that unit_id is the identifier for the rental unit, adding minimal meaning. It does not explain expected format or prerequisites beyond the integer type in the schema.

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 uses a specific verb 'Get', names the resource 'rental unit', and specifies 'by ID', making the tool's purpose unmistakable. It distinguishes itself from list operations (e.g., list_rental_units) and other get tools targeting different resources (e.g., 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?

The phrase 'specific ... by ID' implies this tool is for retrieving a single unit by its identifier, not for listing. However, no explicit guidance is provided about when to use this tool versus sibling tools, nor are any alternatives mentioned.

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