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

With no annotations present, the description carries the full burden of behavioral disclosure, and it does so well. It reveals payment consequences, failure states, retry policies, the need for a wallet or the alternative payment_url path, and even the exact live URL format. No annotation contradiction exists.

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?

The description is long but information-dense: almost every clause carries operational value. It is not structured or bulleted, and the opening 'Go live. $1 USDC first 30 days' is more sales-y than descriptive, but the overall density is high and the key "counter-intuitive" details are embedded in plain language. It earns a 4, not a 5, because a strongly structured description would front-load a purpose statement and then list preconditions, params, error handling, and exceptions clearly.

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?

There is no output schema and no annotations, so the description must; it covers prerequisites (preview_status), payment behavior, retry flows, the slug to live URL mapping, and the no-wallet path. It stops short of stating what the claim call returns on success and does not mention the email parameter. Given the complexity and the number of caveats, the coverage is very good but not complete.

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?

The schema has 0% description coverage, so the description must compensate. It explains uploadId thoroughly by requiring the UUID from inspect, warns against using previewUrl, and clarifies what to pass if only the preview URL is available. It also explains slug semantics via the live URL format, though the email parameter is never mentioned.

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 makes the goal clear through the imperative 'Go live' and the surrounding payment/retry workflow — this is the tool that claims a preview and turns it into a live site. It does not open with an explicit 'Claims an uploaded site' statement, and it relies on context rather than distinguishing itself from all siblings, but it is far from vague or tautological.

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 description gives explicit, actionable usage rules: call preview_status first, do not pay if claimable is false, ask for the slug before paying, retry this tool after PRICE_COMPUTE_FAILED, and do not retry payment after a settlement failure. It clearly states when to proceed and when to avoid using the tool.

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