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

readOnlyHint=true already tells the agent this is a safe read. The description adds the date-range scoping behavior and the REST endpoint, but says nothing about pagination, result ordering, or what a rating record contains. Moderate added value on top of 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 short sentences, front-loaded with the resource, with zero filler. However, the brevity is under-specification rather than efficiency: the two most confusing filter parameters go completely unexplained.

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 tool with five parameters (two of them ambiguous boolean filters) and no output schema, the description should say what a rating record looks like and how the filters behave. Nothing about the return shape or the boolean filter semantics is provided, leaving real gaps.

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 only 20% – just team_id carries a description. The description does not explain the start_date/end_date format expectations or, more importantly, what the lower_ratings and higher_ratings booleans do (presumably filters, but direction and combinability are unstated).

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?

Names the resource (delivery ratings left by customers), the entity scope (team's stops), and the date-range constraint, so the agent knows exactly what is returned. It also cites the underlying endpoint GET /team/{teamId}/customer-ratings. No sibling covers ratings, so sibling differentiation is moot.

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?

Gives no when-to-use or when-not-to-use guidance and does not point at any alternative among the many list_* siblings. The date-range requirement is the only implied precondition, and that is only visible from the schema's required fields.

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