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

Annotations already cover safety signals (read-only, idempotent, closed-world), and the description adds genuine context: geographic coverage of both Miami and Miami Beach, a bundled hotel-cost estimate alongside events, and a stated default window. It does not clarify the granularity of the cost figure ('typical hotel costs on the nights we checked' is loose), 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?

Front-loaded with the core purpose, then scope, then default. The parenthetical list of event examples (Art Basel, Boat Show, Ultra, F1) is long but earns its place by communicating what counts as an 'event' in this domain.

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?

Two optional params, no output schema, annotations present; the description covers scope, content type, and defaults, which is close to enough. The main gap is the imprecise phrasing about hotel costs ('nights we checked') and the absence of any hint about result volume or ordering.

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 already document their YYYY-MM-DD format and defaults, so the description cannot add much beyond the 'between two dates' framing. That framing is consistent with the schema but not richer than it.

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 resource and scope: Miami and Miami Beach events between two dates, plus typical hotel costs for the checked nights. It is distinguishable from likely siblings like event_details (single event) and hotel_prices (price lookup), though it does not name them or draw the boundary explicitly.

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 default window ('next 7 days') is useful and tells the agent the tool works without arguments. However, there is no explicit when-to-use guidance versus alternatives such as hotel_prices, best_nights, or things_to_do; the agent must infer the routing.

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