get_renewal_prices

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that it surfaces expiry status, but doesn't mention rate limits, caching, or whether the price is live/authoritative. Adequate but not rich beyond annotations.

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?

Two tightly-packed sentences: the first states the payload, the second the sequencing. Zero filler, front-loaded with the core purpose.

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 single-param read tool with an output schema, the description covers purpose, returned fields, and workflow placement. Minor gap: no note on failure cases (e.g., unknown domain) or price currency/freshness.

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 single 'hosting' param is fully documented in the schema as 'Domain name the hosting is attached to.' The description adds no syntax or format detail beyond this, so 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?

States specific verb (get) and resource (renewal price) plus names the exact sub-components returned (hosting, domain, options) and expiry status. Clearly distinguishable from siblings like list_hosting_prices or get_hosting, which don't scope to renewal pricing.

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?

Explicitly says 'Check it before renew_hosting,' giving both the trigger condition and the sequencing relative to a related action. This is actionable when-to-use guidance tied to a concrete workflow.

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