get_room_grid

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint. The description adds useful content details (breakfast inclusion, cancellation terms, bed setups) beyond those annotations, but it doesn't disclose other behavioral traits like result variability or the effect of the logged_in flag on member rates. Some value is added, but not comprehensively.

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 that efficiently lists the key aspects without filler. It is concise and well-structured, earning a perfect score for brevity and clarity.

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?

Considering the presence of an output schema and strong annotations (read-only, open-world, idempotent), the description sufficiently covers the tool's purpose. The main gap is the lack of usage context, but that is captured under usage_guidelines. For a read-only inspection tool, it's fairly 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?

Schema coverage is 100%, with all parameters having descriptive text. The description doesn't add parameter-specific semantics beyond hinting at the data types inspected, but the schema already covers the parameters' meaning. The baseline of 3 is appropriate since the description adds no extra parameter insight.

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 specific resource (room grid) and the information it exposes (beds, dimensions, breakfast, cancellation). It is distinct from siblings like get_property_details, though it doesn't explicitly contrast itself with them, so it stops short of a 5.

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 given on when to use this tool versus alternatives such as get_property_details or compare_hotel_prices. It doesn't mention prerequisites, conditions, or scenarios where this tool is preferred, leaving the agent to infer usage.

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