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

Annotations only declare readOnlyHint=true, so the description earns credit for adding the return shape (name, address, type, bedrooms, active flag, pricing/availability settings), which matters because there is no output schema, plus the cursor-pagination model and the underlying API route. It still omits auth/permission needs and default page size.

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?

Three short sentences, front-loaded with the resource and returned fields, then pagination and the API mapping. The endpoint citation is mildly redundant but cheap and locates the tool in Hostfully's API surface.

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 description usefully compensates by enumerating returned fields and flagging cursor pagination, and the schema covers defaults for agency_uid. Missing details such as default page size and behavior when updated_since is combined with cursor are minor.

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%, so the schema already documents limit, cursor, agency_uid and updated_since with formats and defaults. The description adds no parameter-level syntax or constraints beyond what the schema provides, making the baseline 3 appropriate.

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 and resource ('List an agency's properties (rentals)') and enumerates the returned fields, and the plural vs. the singular hostfully_get_property sibling is self-evident. It never names a sibling explicitly, so it falls short of the top band, but an agent can tell what it does at a glance.

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?

There is no when-to-use or when-not guidance and no mention of alternatives such as hostfully_get_property for a single property. The agent must infer that this is the bulk-listing counterpart to the get-one tool. Only the endpoint reference hints at context.

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