Criar saudação

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

No annotations are present, so the description carries the full burden. It indicates the action is creating a greeting, but does not disclose side effects, persistence, authentication, or determinism. For a simple generation action this is acceptable but not fully transparent.

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?

The description is a single, concise sentence with the key information front-loaded. No filler, redundancy, or structure issues.

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 simple one-parameter greeting tool, the description plus schema and output schema provide enough to call it correctly. It does not mention edge cases or return details, but none are essential here.

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?

Input schema coverage is 100%, so the baseline is 3. The description only restates the person target that the 'nome' parameter already documents, adding little extra meaning.

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 uses a specific verb ('Cria') and names the exact resource ('uma mensagem de saudação') plus the target ('para uma pessoa'). It clearly distinguishes the tool's single purpose despite having no sibling tools.

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 intended use is directly inferable: generate a greeting message for a given person. It does not explicitly discuss alternatives or exclusions, but with no sibling tools and a single parameter, contextual guidance is clear.

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