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

Annotations already establish the safe-read profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint=false), so the description only needs to add context — and it does: it discloses that results carry price, seats-left status, and a ticket link, and that sold-out dinners have a waitlist. It does not mention any rate limits or default result ordering, hence not 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 purpose and filter axes, then result contents; every sentence carries information. The city enumeration partially duplicates the schema enum, which slightly dilutes conciseness, but the 'coming soon' note earns it partially back.

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?

An output schema exists, so the description needn't explain return shape, yet it still names the key fields helpfully. With all parameters documented in the schema and 0 required params, an agent has everything needed; only ordering/pagination semantics are left unstated.

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%, so the schema already documents city, limit, start_date, end_date and include_sold_out, making 3 the baseline. The description only marginally adds by flagging that San Francisco is 'coming soon', which contextualizes one enum value.

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 (Find) and resource (upcoming The Dinner Table Club dinner parties), plus the filtering axes (city and date range). This clearly distinguishes it from siblings get_dinner_details (single event) and list_cities (city enumeration).

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 implies usage through 'upcoming ... filtered by city and date range' and notes which cities exist, but never states when to prefer this over get_dinner_details or list_cities, nor any prerequisite or exclusion. Usage is inferable rather than explicit.

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