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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds genuinely new context: data provenance (capcenter.com), freshness (as-of dates), and the privacy scope of quotes (first name + last initial only).

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?

A single dense sentence with the substantive content (sources, figures, links, dates) front-loaded and the language trigger placed last. Slightly overloaded with parenthetical detail, but nothing is wasted.

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 optional parameter, no output schema, and full annotation coverage, the description supplies everything needed: what data comes back, where it comes from, how fresh it is, and how the Spanish variant behaves.

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 the single enum parameter is fully documented in the schema, so baseline 3 applies. The description only restates the Spanish behavior and adds Spanish trigger vocabulary (opiniones, calificaciones), which is mildly useful but not new semantics.

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 exact resource (CapCenter's public ratings from Zillow, Google, BBB) plus the supporting content (source links, as-of dates, published client quotes). No sibling tool covers reviews, and the description makes that scope unmistakable.

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 only implied — an agent can infer this is the tool for reputation/social-proof questions, but the description never states when to call it or when another tool (e.g. get_mortgage_quote) is the better fit. No exclusions or ordering guidance are given.

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