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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds only marginal behavioral context: that the result may be a renter or host inquiry and may include a 'promise'. It says nothing about not-found behavior or access requirements.

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 short sentence with the core subject front-loaded and no filler. The sentence-fragment phrasing ('One inquiry...') is slightly terse but efficient.

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 carries the burden of hinting at the return shape, and it does so only partially ('including its promise if one was made'). For a simple read-only, single-parameter tool whose safety profile is covered by annotations, this is minimally adequate but leaves the response contents underspecified.

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 0% and the description never mentions inquiry_id or its type/format expectations. With a single parameter named inquiry_id the meaning is mostly self-evident from the schema, but the description does nothing to compensate for the missing schema documentation.

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?

The description names a specific resource (a single inquiry) and its scope ('renter or host'), which distinguishes it from the sibling list_inquiries without opening either schema. It stops short of saying exactly what an inquiry object contains, so it's clear but not maximally specific.

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 guidance and no named alternative, even though list_inquiries and respond_inquiry/cancel_inquiry sit right next to it. An agent must infer that this is the single-record fetch rather than the list or mutation tools.

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