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

Adds meaningful behavior beyond annotations: KEILTY contacts the owner directly, the request commits the owner to nothing, and the owner signs any agreement personally. These clarify consequences of the non-read-only, open-world call. It stops short of stating what the caller receives back or confirmation behavior, keeping it at a 4.

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 tight sentences, front-loaded with the what and immediately followed by the consent and frequency constraints. No filler or repetition 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?

The consent/commitment framing is strong for a high-stakes write tool with no output schema, but with 71% of parameters undocumented anywhere and no mention of what happens after submission beyond 'KEILTY contacts the owner', it is only minimally sufficient.

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 only 29% across 14 parameters, so the description carries the burden of compensating, yet it explains no parameter semantics. The only hint ('owner's contact details', 'once per property') echoes the already-described owner_consent field rather than illuminating the other 13 parameters.

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 ('submits') and resource ('rental evaluation request') plus the recipient (KEILTY) and the actor it acts on behalf of (the owner). This is unmistakably the only write/submit tool among siblings that are all reads (get_pricing, get_booking_link, check_fit, etc.).

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?

Explicit gating conditions: requires the owner's explicit consent to share contact details, and must be called only once per property. These are clear when/when-not constraints, and no sibling competes for this action, so no alternative needs naming.

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