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

Annotations already establish readOnly/idempotent/non-destructive, so the bar is lower; the description still adds real value by disclosing that deletes remain recoverable for 14 days (implying restore_privacy_data) and by flagging 'Names people by email: PERSONAL DATA'. It says nothing about result size or pagination, which keeps it from a 5.

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 scope statement is front-loaded and every enumerated clause corresponds to a real returned category, so nothing is filler. It is one very long semicolon-chained sentence, which is dense but still scannable.

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 enumeration effectively serves as the return-value contract, and the PII warning plus the 14-day restore window give the agent the operational context it needs. The only missing piece is any notion of result volume or truncation for the audit log and deleted-people lists.

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 both parameters (site_id, user_goal) are fully documented in the schema, so the description's silence on parameters does not lose information. Baseline 3 is appropriate; nothing here adds meaning beyond the schema.

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 opens with a specific verb+resource ('The site's privacy operations') and then enumerates exactly what is returned: retention policy, intake settings, legal links, vendor counts, recoverable deletions, and the audit log. An agent can distinguish this from siblings like get_compliance_status or list_privacy_vendors because the enumerated scope makes the boundary clear.

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?

Usage is implied by the content enumeration — an agent can infer this is the overview call for a site's privacy posture — but the description never states when to prefer it over get_compliance_status, list_privacy_vendors, or the retention-cleanup tools. No exclusions or alternatives are named.

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