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

Annotations only declare readOnlyHint=true, so the safety profile is already known. The description adds value by disclosing the returned field set (contact details, commission rate, permissions) and the optional filtering behavior — meaningful context beyond the annotation. However it says nothing about pagination, result limits, or whether agency_uid scoping constrains results.

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?

A single front-loaded sentence covers purpose, returned fields and the optional filter; the trailing endpoint reference is compact and useful. Slightly dense but no wasted sentences.

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 read-only list tool with a 100%-covered 2-param schema and no output schema, the description is nearly sufficient — it names the returned fields, which the absent output schema would otherwise leave unknown. Missing only pagination/limit behavior and explicit sibling routing to be fully 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% and both parameters are fully documented in the schema, including the agency_uid default and the cross-reference to list_agencies. The description restates the optional search filter but adds no syntax or format detail beyond the schema, so the baseline of 3 applies.

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 a specific verb (List) and resource (the agency's property owners) and enumerates the returned fields — contact details, business name, commission rate, permissions — which distinguishes it from list_guests, list_properties and other list siblings. The name, title and description all align without redundancy.

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 description mentions the optional search-string filter, implying when to use it, but gives no explicit when-to-use vs alternatives or exclusions. With 19 sibling list/get tools, an agent gets no routing guidance (e.g. use this rather than search-style tools).

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