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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds real behavioral value beyond that by disclosing the three possible status outcomes and defining what 'live' means (the person signed in and claimed the page), plus the fact that embed code comes back on success. It stops short of explaining what 'gone' means or whether repeated polling is expected.

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 tight sentence with no filler; every clause carries information (origin, states, embed code). The one weakness is that the leading 'Whether…' construction delays the actionable framing slightly compared with a verb-first opening.

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?

For a one-parameter read tool with no output schema, the description covers the essentials: where the argument comes from, what states can be returned, and what accompanies a live page. Details like polling expectations or the semantics of 'gone' are the only notable omissions.

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% and the schema already documents that the single parameter is the stp_… setup key returned by set_up_booking_page. The description only restates that provenance, adding no format or validation detail beyond the schema, 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 description names the resource (a booking page created by set_up_booking_page) and enumerates the outcome states it reports — live, waiting, or gone — plus the embed code. That is specific enough to distinguish it from the sibling setup tool, though it phrases the purpose as a noun clause ('Whether…') rather than stating a verb like 'check' up front.

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?

Usage is implied by the reference to set_up_booking_page and its returned key, so an agent can infer this is the follow-up call after setup. However, there is no explicit statement of when to call it (e.g., polling after setup, after the person has had time to sign in), no when-not-to-use guidance, and no named alternative.

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