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

No annotations are provided, so the description carries the full burden. It usefully discloses error behavior (status not_found with a hint) and that review dates are content dates, which is genuine behavioral context, but it omits read-only/reversibility, whether results are cached, or rate limits, and the 'separate current native verification projection' phrasing is opaque jargon.

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?

Four sentences that are mostly front-loaded, but the middle clauses about 'native verification projection' and 'guide review dates are content dates' are dense and add ambiguity without clear payoff. Some sentences do not earn their space for an agent trying to act.

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 and no annotations, the description must cover returns and it does: it names the instruction payload, the verification projection, and the not_found status with a hint. For a single-parameter lookup this is largely complete, though the two return components could be described more plainly.

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 description coverage is 100%, and the single param is already documented as 'Guide slug, domain, alias, or a URL on the broker's site.' The description only restates the same accepted forms and adds one concrete example ('spokeo'), so it does not meaningfully enrich beyond the schema. Baseline 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?

States a specific verb+resource ('step-by-step opt-out instructions') scoped to 'one people-search or data-broker site', which implicitly distinguishes it from the plural list_opt_out_guides sibling. However, it never names list_opt_out_guides or get_removal_route to make the singular-vs-list and instructions-vs-route distinction explicit.

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 tells you what input it accepts (slug, domain, alias, or URL) and that a missing guide returns not_found with a hint, so the 'when it applies' is implied. But there is no explicit when-to-use-this-vs-alternative guidance against the many sibling lookup tools, leaving the agent to infer.

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