Get Meal Plan For Date

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds nothing beyond that — no note on empty-day behavior, ordering, or how much data is returned (the output schema exists but the description offers no framing).

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 front-loaded sentence with zero redundancy. It is efficient but so terse that the brevity costs the usage and behavioral information an agent would want.

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 single-optional-parameter read tool with an output schema and full annotations, the definition is minimally sufficient to call correctly. It omits the 'today default' nuance and any hint about result shape, which the schema covers but the description could reinforce.

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% and the 'day' parameter is fully documented in-schema ('YYYY-MM-DD. Default: today (server date); pass the user's local date when known'). The description adds no format or defaulting meaning beyond that, so baseline 3 applies.

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 (Get) and resource (meal plan entries) with a clear scope qualifier ('for one day'), which separates it from the entry-creating siblings. It does not explicitly name or contrast with list_meal_plans, which is the nearest ambiguous alternative.

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?

There is no explicit when-to-use or when-not-to-use guidance and no named alternative. An agent must infer the distinction between this and list_meal_plans, and there is no mention of whether ranges or past/future days are supported.

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