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

With readOnlyHint already declaring this a safe read, the description adds the return content (recipes with nutrition) and pagination behavior via limit/offset. However, it omits notable constraints like the premium-subscriber-only access and the max-10 limit, which the agent would need spelled out elsewhere.

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?

Three tight sentences with the core purpose front-loaded, followed by the return content and pagination guidance. No redundancy, though the pagination sentence is slightly verbose.

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?

Adequate for a read-only list tool with a fully documented schema, but it leaves out meaningful behavioral details (premium subscriber gating, max 10 results, no-result behavior) that affect correct invocation, and there is no output schema to absorb them.

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 all four parameters fully including defaults, ranges, and premium-only notes. The description adds pagination intent but no syntax or format detail beyond the schema; 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+resource ('Get a list of recipes') and the retrieval keys (recipe name or ingredients), and notes return content (nutrition information). It is clear what it does, though it doesn't explicitly distinguish itself from similarly named siblings like getNutrition or getNutritionItem.

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?

It explains how to access more results via pagination, which is actionable usage guidance, but it gives no explicit when-to-use vs alternatives (e.g., vs getNutritionItem or searchCocktails). Usage is implied rather than contrasted with siblings.

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