monthly_report

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

There are no annotations, so the description must carry the behavioral disclosure burden. It does not state whether this is read-only, what format the report takes, what data is included, or whether it has side effects like file generation or email delivery.

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 one short, focused sentence with no filler or redundancy. It is front-loaded with the action and object, though it sacrifices useful detail for brevity.

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 a single optional parameter, no annotations, and multiple closely related sibling tools, this description is too thin. An agent cannot confidently decide when to call this versus summarize_expenses or export_expenses_csv, nor understand how 'months' shapes the report. The existence of an output schema helps, but not enough.

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 schema coverage is 0% and the description never mentions the 'months' parameter. The agent is left to infer that it controls the reporting period, and the default of 6 is only visible in the schema, not explained in context.

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 states a clear action and object: 'Generate a monthly expense report.' It is not vague or tautological, but it does not differentiate itself from sibling tools like summarize_expenses or export_expenses_csv, which could overlap in purpose.

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 given on when to use this tool versus alternatives such as summarize_expenses or list_expenses. The word 'monthly' implies a cadence, but there is no explicit context, prerequisites, or exclusion criteria.

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