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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered; the description adds the important behavioral boundary that results are static catalog facts, not live availability. It does not discuss permissions, rate limits, or refresh/caching of the static data, so it stops short of full disclosure.

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 sentences: the first front-loads the payload, the second front-loads the scope limit and the redirect. No filler or redundant restatement of the title.

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 small, bounded, read-only catalog tool with no output schema, the description supplies the returned fields, the dataset size, and the critical limitation versus live availability. Nothing an agent needs in order to call it correctly 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 coverage is 100% and the single optional roomtype filter is fully documented in the schema, so the baseline applies. The description mentions room types only as a returned field, adding no filtering semantics such as behavior when roomtype is omitted or invalid.

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 plus the exact payload: the twelve New Leaf properties with name, address, phone, room types sold online, rates and booking URL. An agent can distinguish this inventory listing from the availability/rate siblings without opening the 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?

Explicitly bounds the scope ('static facts only — it says nothing about whether a room is free tonight') and names the alternative, find_rooms, for that need. When-to-use and when-not-to-use are both stated outright.

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