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

Annotations already establish readOnlyHint and openWorldHint, so the safety profile is covered. The description adds genuinely useful operational context: the default date behavior and the publication window of today-3 to today+14, which tells an agent which requests will fail. It does not mention pagination or payload size, keeping 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?

Two tightly packed sentences, front-loaded with the core action and followed by the date constraint. The parenthetical field list is dense but earns its place by telling the agent what comes back. No filler or restated boilerplate.

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 an output schema present, the description need not explain return shape, yet it helpfully summarizes it. Annotations cover the read-only/open-world profile and the date window is spelled out. The only real gap is the unspecified 'meal' parameter, which an agent must infer from the enum.

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 67%. The description reinforces the date parameter's semantics (default today, valid window) and implies meal coverage, but the 'meal' enum has no schema description and receives no explanation in the description either, so one parameter remains undocumented across both surfaces.

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 and resource ('Get the menu of one dining hall') and enumerates the payload in useful detail (meals, stations, dishes, traits, allergens, nutrition). It implicitly separates itself from search_dishes/filter_dishes by scoping to a single hall, but never names an alternative, so it stops short of full sibling differentiation.

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?

Gives a clear context cue (single hall, date defaults to today) and a real constraint (menus exist only from today-3 to today+14), but offers no when-not guidance and never points to search_dishes or filter_dishes for cross-hall or criteria-based lookups. Usage is implied rather than prescribed.

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