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

Annotations already declare this as a non-read-only, open-world, non-idempotent write operation, so the safety profile is partly covered. The description adds only that a live URL is produced, but says nothing about cost, whether repeated calls create duplicate sites (despite idempotentHint=false), what dry_run does, or what the truncated 'listed on...' clause implies about side effects.

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 sentence that is cut off with an ellipsis, so it is under-specified rather than concise. The important scoping detail is literally missing from the end of the string.

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 an 8-parameter creation tool with no output schema and no annotation detail about side effects, the description is far too thin. It omits what a created site includes, how the items/shop/template options shape the result, and what happens on failure or repeat invocation.

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% across 8 parameters, so the description must compensate and largely fails: it only implies the `prompt` input and hints that `name` maps to the URL. Eight parameters including `items`, `price`, `currency`, `payments`, `template` (the only enum), `contact`, and `dry_run` are left completely unexplained.

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 conveys that a natural-language prompt yields a generated live site at a predictable URL, which is a recognizable verb+resource. However, it is truncated mid-sentence ("listed on...") and never states how this differs from siblings like app_publish, site_publish, or site_list, so an agent must infer the distinction.

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 or when-not-to-use guidance and no mention of alternatives such as app_publish for updating an existing app. The only implied usage cue is 'describe the business in a sentence', with no prerequisites or follow-up steps described.

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