tax_summary

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

Only 'read-only' is declared. No other behavioral traits like compute source, aggregation, or performance implications. With no annotations, the description should provide more detail.

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?

Extremely concise (3 words) but under-specified. Fails to convey necessary information beyond the title-level summary.

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?

Despite having an output schema, the description omits critical context on parameter usage and result interpretation. For a financial tool, more detail is essential.

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 has two parameters (to_date, from_date) with no descriptions in schema or description. Agent cannot infer their purpose, format, or effect. Schema description coverage is 0% and description does not compensate.

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 the tool provides a tax summary snapshot and is read-only. It distinguishes from sibling financial reports, but lacks specifics on what the snapshot contains.

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 versus alternatives like profit_and_loss or balance_sheet. No mention of date range usage or other context.

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