Quote domain restore

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

Annotations only declare the generic safety profile (readOnlyHint false, destructiveHint false, openWorldHint false). The description adds meaningful context the annotations lack: that the quote returns a final price before any payment and that paid domains:renew scope/caps are required for API keys, which is a real auth prerequisite an agent must satisfy.

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?

Three short sentences, each carrying distinct information (purpose, return behavior, auth requirement) with the identifying scope front-loaded and zero filler.

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?

With no output schema, the description usefully states that the final price is returned, and it covers the redemption pre-condition and scope requirement. It leaves the relationship to confirm_domain_restore implicit, but nothing essential for a correct call is missing.

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% and all three parameters (domain, domain_id, idempotencyKey) are documented in the schema itself, so the baseline is 3. The description adds only the implicit notion of an 'owned' domain and no format or mutual-exclusion guidance beyond what the schema already gives.

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 and resource ('Create a restore quote') plus the precise pre-condition ('for an owned domain in redemption'), which cleanly separates it from quote_domain_register, quote_domain_transfer and quote_domain_renew without needing to name them.

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?

Explains the context in which it applies (a domain already in redemption) and places it in the payment flow ('the final price is returned before payment'), implying it precedes confirm_domain_restore. It does not state explicit exclusions or name the confirmation sibling.

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