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

readOnlyHint=true already tells the agent this is a safe, non-mutating read. The description adds the returned field set, which is useful, but says nothing about pagination behavior despite limit/offset parameters, nor about sort behavior or result volume. Adds some value beyond annotations, but not rich.

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: the first front-loads what is returned, the second delivers the filter surface, and the API endpoint tag is a compact, useful trailing note. 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?

With no output schema, the description compensates by naming the returned fields, and it covers the full filter surface. The only meaningful gap is the absence of pagination guidance for a list tool that exposes limit/offset and can return up to 500 records.

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 every one of the 12 parameters is already documented in the schema, making 3 the baseline. The description echoes the filter set but adds no format or interaction detail beyond what the schema provides (e.g. it doesn't explain how availability date range interacts with guest count).

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 account's properties/listings) and enumerates the fields returned, so the agent knows exactly what comes back. It doesn't explicitly differentiate itself from the sibling hostaway_get_listing, but 'list' vs 'get' is unambiguous enough that no confusion arises.

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 enumerates the available filter dimensions (name, city, country, type, availability window, guest count, status), which implies usage but never states when to pick this over hostaway_get_listing or how the filters combine. No exclusions or prerequisites are given.

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