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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, and openWorldHint=false, so the agent knows this is a non-idempotent write that is not destructive. The description adds only the '(text only)' constraint, implying no media attachments, which is a modest but real behavioral detail; nothing is said about what gets mutated or whether the reply is visible/public.

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 zero filler and the resource and constraint front-loaded. It is efficient, though arguably terse to the point of under-specifying a mutation tool.

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 described, and the parameters are fully documented in the schema. What is missing is the surrounding context an agent needs for a non-idempotent write: whether a prior booth request must exist, and how this differs from the other answer/reply siblings.

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 id and text are already documented in the schema, and the description adds no syntax, format, or length guidance for either. Baseline 3 is appropriate when structured fields carry the parameter burden.

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 (answer) and resource (booth request) plus a scope constraint (text only), which separates it from the request-creating sibling booth_request. However, it does not distinguish itself from other reply-shaped siblings such as free_reply, relay_add, or answer, so an agent cannot route with full confidence from the description alone.

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 explicit when-to-use statement, no prerequisites (e.g. must a booth request exist first?), and no named alternative among the many reply/answer siblings. Usage is only implied by the tool name.

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