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

Annotations only declare readOnlyHint=true, but the description goes further by disclosing the shape of the response (ask/mail/available) and the plan prerequisite ('available says whether the plan has ratings (Pro and higher)') — useful gating context not in the schema. It does not mention the mutating counterpart `set_rating_settings`, a minor omission for a settings reader.

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?

Roughly two sentences, front-loaded with the subject (whether customers are asked for a rating), and every clause carries information about a returned field or a sibling redirect. The nested parentheticals make it dense, but no sentence is 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 input parameters and no output schema, the description correctly shoulders the burden of explaining the returned fields and the plan condition, which it does. Nothing essential is missing for a correct call; only the link to `set_rating_settings` would make it airtight.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a parameterless tool applies. All descriptive effort is correctly spent on output semantics instead.

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 concretely defines the resource: the workspace's rating configuration, with the meaning of each returned flag (`ask`, `mail`, `available`). It explicitly separates itself from `get_ticket` (per-ticket stars) and `get_report` (totals), so an agent can tell which tool to reach for. The verb 'get/retrieve' is only implied by the title, which keeps it just short of a 5.

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?

It names the alternatives and the data they own ('A ticket's own stars are in get_ticket, and the totals in get_report'), which is real routing guidance rather than nothing. It lacks an explicit when-to-use trigger (e.g., 'call this before editing settings with set_rating_settings'), so it stops at 4.

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