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

Annotations already declare readOnlyHint=true, so the safety profile is covered; the description adds useful substance by enumerating the resource attributes available (capacity, price, rate, floor, amenities) and the OfficeRnD endpoint. It does not discuss pagination semantics beyond what the schema's cursor params imply, but the added context is meaningful.

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?

Two tight sentences with the resource scope and purpose front-loaded and the downstream consumer linkage second. No 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?

For a 6-parameter, all-optional list tool whose schema is fully documented, the description covers purpose, scope and use case. With no output schema, a brief note on pagination or result shape would make it fully self-contained, but nothing essential is missing.

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 100%, including type enums and cursor semantics, so the schema carries the parameter burden. The description's enumeration of attributes refers to returned resource fields rather than input parameters, so it adds little parameter-level meaning.

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?

Specific verb (list) plus concrete resource scope (meeting rooms, desks, hot desks, private offices) and the attributes returned. It explicitly ties itself to officernd_create_booking as the consumer of the resource _ids, so an agent can place it against siblings without opening a schema.

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?

It gives a clear usage condition — fetch resource _ids before calling officernd_create_booking — which is genuine routing guidance. It doesn't state when not to use it or name an alternative list tool, so it falls short of a 5.

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