get_budget_status

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

No annotations are provided, so the description must disclose behavioral traits. It states the core purpose but does not mention the role of the optional 'budget' parameter, whether the operation is read-only (implied by 'check' but not explicitly stated), or any side effects. The lack of detail about parameter behavior and potential default handling leaves significant gaps.

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 that communicates the essential purpose without redundancy. It is front-loaded and every word contributes to understanding what the tool does.

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 tool with a single optional parameter and no annotations, the description is too minimal to be complete. It lacks explanation of the 'budget' parameter's behavior and provides no guidance on when to use this tool versus siblings. While the output schema exists, the description’s omission of parameter semantics makes it inadequate for correct invocation.

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 has one parameter 'budget' with 0% description coverage, and the description fails to explain its meaning or how it affects the result. The parameter is not mentioned at all, leaving the agent to infer its purpose from the name alone. With no schema descriptions, the description should compensate but does not.

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 'Check' and a clear resource 'budget vs actual spending for current month', which accurately defines what the tool does. It distinguishes itself from sibling tools like get_summary or list_expenses by focusing on budget comparison rather than summary or listing.

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: when you want to check budget status for the current month. However, it provides no explicit alternatives or exclusions, such as suggesting get_summary for broader overview or search_expenses for specific transactions. No when-not-to-use guidance is given.

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