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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds value by disclosing what data comes back, but says nothing about behavior on an unknown slug, whether results are cached, or rate limits.

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?

One front-loaded sentence, no filler. The field list is dense but each item tells the agent what to expect back, which is useful given there is no output schema.

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, the enumerated return fields do real work in telling the agent what to expect, and the single-parameter schema is self-documenting. The main remaining gap is error behavior for an invalid or unknown property slug.

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 single 'property' parameter is fully documented in the schema (100% coverage, including the slug pattern and example format), so the schema carries the burden. The description adds no additional meaning about the identifier beyond what the schema already states.

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?

States clearly that it returns the full record for a single property, and the field enumeration (beds, amenities, house rules, prices, photos) makes the scope concrete. It does not name siblings like list_properties or search_stays, but the singular 'one property' framing implicitly separates it from those list tools.

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 when-to-use statement, no prerequisites, and no alternatives named. An agent has to infer that this is the follow-up call after search_stays or list_properties yields a slug; nothing in the description says that.

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