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

Annotations already cover readOnly/idempotent/non-open-world, so the description's added value is disclosing data provenance and content: prices sourced from official sites, plus duration and transport details in results. That is genuine context beyond the structured fields. It does not address result volume, staleness of prices, or whether a group plus query are combined, so it stops short of full disclosure.

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 sentence, front-loaded with the resource and scope, with the long parenthetical earning its place by defining coverage breadth. The trailing clause about prices, time allowances, and transport efficiently conveys output content. Slightly dense but no wasted wording.

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 zero-required-parameter, read-only browse tool with no output schema, the description covers what content exists but not how to call it: no explanation of the group enum's effect, no semantics for query, and no indication of how results are shaped or how many. Adequate for orientation, incomplete for correct invocation.

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 0%, so the description must carry parameter meaning, and it only partially does: the enumerated topics loosely mirror the group enum values (outdoors, culture, family, day-trips, free) but no parameter is named or explained. The purpose of 'query' — free-text keyword vs. destination narrowing — is left entirely undefined, and whether both parameters can be combined is 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 concretely (things to do in and around Miami) and enumerates the coverage areas — Everglades, Biscayne, beaches, Vizcaya, PAMM, Wynwood, Little Havana, zoo, Keys, free options — plus the data included (prices from official sites, time needed, transport). It is clearly a curated attractions guide rather than an events or booking tool, though no sibling is named to sharpen the boundary.

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: the topic list suggests it fits general sightseeing/planning requests, and the mention of 'free things' hints at a budget use case. There is no explicit when-to-use or when-not-to-use guidance versus siblings such as whats_on, best_nights, nightlife, or hotel_prices, so the agent must infer routing from the topic coverage alone.

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