get_budget_comparative_report

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

No annotations are present, so the description bears full responsibility for disclosing behavioral traits. It only says 'Returns budget comparative report' without mentioning whether it is read-only, requires authentication, handles large data sets, or has any side effects. For a likely read-only report, the lack of explicit safety indication is a gap.

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 overly brief (one short sentence) to the point of under-specification. While conciseness is valued, this lacks essential structure and context, making it incomplete rather than efficient.

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 complexity of the input schema (10 parameters, nested objects), no output schema, and no annotations, the description fails to provide sufficient context. An agent cannot determine what the report contains, how to interpret the output, or how to properly use the filters, making the tool hard to invoke correctly.

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 provides no additional meaning for any of the 10 parameters, including the nested 'properties' object. Parameters like 'period_from' and 'level_of_detail' have no explanation of format or allowed values, leaving the agent to guess.

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?

Description states 'Returns budget comparative report for the given filters.' This clearly identifies the tool's action and resource. However, among over 45 sibling report tools, there is no differentiation from other budget reports like 'get_annual_budget_comparative_report', so it's not fully distinguishing.

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 guidance is provided on when to use this tool versus alternatives. There are multiple budget-related reports in sibling tools (e.g., get_annual_budget_comparative_report, get_annual_budget_forecast_report), but the description does not explain the differences or appropriate contexts.

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