get_charges_summary

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

No annotations provided, so the description carries full burden. It only states it 'gets' a summary without disclosing side effects, aggregation behavior, or any other behavioral traits. Minimal behavioral context.

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?

Description is one short sentence, which is under-specified rather than efficiently packed. It is not verbose but lacks necessary content.

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 simple tool with 2 params and an output schema, the description is too minimal. It doesn't explain what 'charges summary' contains or how it differs from other billing tools. Output schema exists, so return values are covered, but the description should provide more context.

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%. Description does not mention parameters at all. The schema provides titles 'Start Date' and 'End Date' which are self-explanatory, but no format or constraints are clarified. The description should add date format or context but fails.

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 clearly states verb 'Get' and resource 'monthly charges summary' with a date range constraint. It distinguishes from siblings like get_charges_breakdown by focusing on summary rather than breakdown, but does not explicitly differentiate.

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 on when to use this tool vs alternatives (e.g., get_charges_breakdown for detailed charges, get_invoice for invoices). No exclusions or when-not to use.

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