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

The description adds the site-scoping constraint, which is a small behavioral detail beyond the annotations. However, it does not disclose what is returned, error behavior, or dependencies; the read-only safety is already covered by readOnlyHint=true.

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 a single short sentence with no filler and the essential scope is front-loaded. It is appropriately minimal for such a simple tool definition.

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 one well-documented parameter and readOnly annotations, minimal information may be sufficient. However, there is no output schema and the term 'Cookie Solution' is ambiguous next to 'Privacy Cookie Policy', so the description would benefit from clarifying the return value and how it differs from similar getter tools.

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%, so site_id is already documented. The description's 'for a site' reinforces the parameter's role but adds no format, source, or validation details, so the baseline score of 3 is appropriate.

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 names a clear verb-resource pair ('Get' + 'Cookie Solution') and scopes it to a site, which distinguishes it from the create/update/delete siblings. However, it does not differentiate 'Cookie Solution' from the related sibling 'get_privacy_cookie_policy', leaving mild ambiguity.

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 provides no guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. The verb 'Get' weakly implies read-only retrieval, but no explicit usage context is given.

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