soma

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

No annotations were provided, so the description carries full burden. It states the operation (addition) but does not disclose edge cases, return type, or behavior for non-number inputs. For a simple arithmetic tool, this is minimally acceptable.

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 extremely concise (3 words). While it is efficient, it could be slightly more informative without sacrificing brevity. The front-loading is fine: the purpose is stated immediately.

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 the tool's simplicity (adding two numbers), the description is nearly complete. However, it does not explain the return value or handle edge cases like large numbers. The presence of an output schema partially compensates, but it is not shown 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?

Schema description coverage is 0%, and the description does not add any meaning beyond the parameter names (a and b). It fails to describe what each parameter represents or any constraints. Baseline should be higher due to low coverage, but description provides no compensation.

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 'Soma dois numeros' (Adds two numbers) clearly states the verb and resource. It is specific and distinguishes the tool from sibling tools like ping or buscar_jurisprudencia, which have different purposes.

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?

No explicit guidance on when to use or alternatives. However, the tool's purpose is straightforward (summing numbers), so usage is implied. No exclusions or when-not-to-use advice is provided.

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