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

No annotations are provided, so the description carries the full behavioral burden. It only states what the tool does and says nothing about read-only nature, permissions, rate limits, or what the comparison returns, leaving key behavioral traits 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 a single, front-loaded sentence with no redundant or filler content. It is as concise as possible for its limited scope.

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?

With no output schema and no annotations, the description should explain what the comparison returns (e.g., which attributes are compared) to help an agent invoke it correctly. It only states the basic purpose and parameter count range, leaving the return behavior unaddressed.

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%, so the description should compensate. It adds only 'by id' and the 2–5 range, both of which are already conveyed by the property name 'ids' and the schema's minItems/maxItems constraints. No id format or source is explained.

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 states a specific verb (comparison), resource (nursing homes), and scope (2–5 by id). It is clear what the tool does, but it does not explicitly differentiate itself from siblings like get_home or search_homes.

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?

Usage is implied: use it when a side-by-side comparison of multiple homes is needed. There is no explicit guidance on when to prefer this over get_home, search_homes, or list_cities, and no exclusions or prerequisites are mentioned.

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