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

Annotations already establish read-only, idempotent, non-destructive, closed-world behavior, so the description need not repeat safety. It adds meaningful context: amounts are current and gross, include validity date and official source, and grade can optionally limit results to one group. Error handling and pagination are not discussed, but an output schema exists, reducing that burden.

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?

Two sentences, front-loaded with what data is returned, followed by the optional filter. There is no filler or redundant wording.

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 simple two-parameter read-only tool with an output schema and full schema descriptions, the definition is complete enough: it states scope, returned data context, and the optional group filter. The required scheme choices are fully enumerated in the schema.

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 coverage is 100%, so the baseline is 3. The description adds that grade is optional and limits results to a single group, with examples matching the schema, providing useful semantic clarification beyond the schema field descriptions.

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 names a specific verb and resource (get pay table) and states the returned content: current gross monthly amounts per group and step, with validity date and official source. It is clearly distinct from generic siblings like fetch/search by domain, but it does not explicitly name or contrast alternative tools.

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 use for retrieving current pay table amounts and explains that grade can optionally narrow results to one group. However, it gives no explicit when-to-use versus when-not guidance or alternatives among sibling tools.

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