getMonthBudgets

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 states 'List' which implies a read-only operation, but it does not disclose other behavioral traits such as authentication requirements, data scoping (e.g., user-specific), or error handling. The month-specific scoping adds some context but is minimal.

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, front-loaded sentence with no extraneous words. It earns its place by clearly and efficiently stating the tool's purpose.

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?

Although an output schema exists, the description omits crucial context about what budgets are returned, whether they are user-specific, and when to use this tool versus yearly/all budgets. With no annotations and minimal parameter info, the description is insufficient for a tool with two required parameters.

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?

The input schema has 0% description coverage, and the description only hints at the month parameter via 'mês específico' without mentioning the year parameter or explaining how the parameters should be used. The description does not compensate for the lack of schema descriptions.

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 'Listar' (list) and resource 'metas' (budgets) with a clear scope 'de um mês específico' (of a specific month), which distinguishes it from siblings like getBudgets (all budgets) and getYearBudgets (yearly budgets). It leaves no doubt about 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 monthly budgets but does not explicitly state when to use this tool over getBudgets or getYearBudgets, nor does it mention any exclusions or alternatives. The context is inferred but not spelled out.

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