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

Annotations already declare the mutation profile (readOnlyHint=false, idempotentHint=false, destructiveHint=false), so the safety picture is covered. The description adds genuine behavioral constraints (text only, 10+ chars, no links) but says nothing about what happens after the request or how the booth responds / whether it is async.

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 front-loaded sentence with the verb, target, and input constraints; no filler. The constraints are placed parenthetically right where they matter.

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 output schema exists so return values need no prose, and the annotations cover the mutation profile. However, for a tool sitting among several booth/* and answer siblings, the description omits any routing context, leaving the agent to guess when this beats booth_reply or booth.

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%, so the baseline is 3, but the description adds real validation semantics for the 'text' param (text-only, minimum length, link prohibition) that the terse schema description ('what you need') does not convey. The api_key param remains unexplained in the description, but its schema entry is self-explanatory.

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 clear verb+resource ('Ask the booth for help') with an inline constraint set, so the agent understands the action. It does not differentiate itself from siblings like booth, booth_reply, or answer, so an agent must infer where this fits.

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?

The phrase 'for help' hints at intent but gives no explicit when-to-use, when-not-to-use, or alternatives (e.g. booth_reply). The constraints on text are input rules, not usage routing.

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