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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered structurally. The description's only added behavioral detail is 'text-only'; it says nothing about what is returned, whether requests are public to other users, or how the booth's lifecycle works.

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?

It is a single terse line with no filler, so nothing is wasted, but it is a sentence fragment that is under-specified rather than genuinely concise. It front-loads the resource name, so an agent at least reads the resource first.

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?

An output schema exists, so return values need not be explained, but the description still omits what the tool does, when to call it, and how it relates to booth_request and booth_reply. For a tool in a dense sibling cluster with a multi-step reply flow, that leaves the agent unable to route correctly.

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% and the single api_key parameter is fully documented in the schema, including its fallback role when no Authorization header is sent. The description adds nothing about parameters, but with high coverage the schema does the heavy lifting, so the baseline 3 applies.

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 fragment 'The text-only request booth: open requests' restates the title and never supplies a verb describing what the tool actually does. It is ambiguous whether it opens requests, lists open requests, or enters a booth, and it does not distinguish itself from the sibling tools booth_request and booth_reply.

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, no mention of booth_reply or booth_request as alternatives, and no prerequisite or exclusion stated. The only signal is the word 'text-only', which hints at a modality constraint but not a trigger condition.

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