tool_get_daily_values

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

No annotations are provided, so the description carries the full burden. It clearly indicates a read-only operation ('anzeigen') with no side effects. While it does not disclose specifics like data caching or update frequency, the tool's simplicity (no inputs, static data) makes this sufficient.

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 concise sentences, front-loaded with the primary purpose. Every word earns its place. No redundancy.

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?

Given zero parameters and no output schema, the description is largely complete. It specifies the audience (adults) and the data source (FDA). However, it could be improved by noting that the output is a list or table of nutrients with values, but this is minor.

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?

There are no parameters, so the description does not need to add meaning beyond the schema. Baseline of 4 is appropriate because the schema coverage is 100% and the tool has zero parameters.

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?

The description explicitly states the tool shows daily recommended nutrient intake (DRI) for adults, specifically FDA Daily Values. This distinguishes it from sibling tools like tool_get_nutrient_info, which likely provides general nutrient data. The verb 'anzeigen' (display) is specific and matches the tool's function.

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 for retrieving adult DRI values but does not provide explicit guidance on when to use this tool over alternatives like tool_get_nutrient_info or context-specific exclusions. For a zero-parameter tool, the intended use is clear, but alternatives are not addressed.

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