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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description adds only the code format example, contributing modest context beyond the structured fields.

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?

A single short fragment, front-loaded with no filler. It is efficient, though the terseness edges toward under-specification rather than tight conciseness.

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?

The tool is trivial (no params, output schema present, annotations covering safety), so little is strictly required. Still, it omits whether this is a complete static reference list and how the codes relate to sibling tools, leaving the agent to guess at practical use.

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?

There are zero parameters, so the baseline is 4. The '2210 Information Technology' example adds a small amount of meaning by showing the data shape the agent will receive.

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 the resource ('Occupational series codes') and gives a concrete example ('2210 Information Technology'), so an agent can infer it returns a lookup list. But it is a bare noun phrase with no verb and no differentiation from the otherwise identical siblings list_agencies and list_pay_grades.

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 when-to-use guidance, no indication of why to call this versus list_agencies/list_pay_grades, and no mention that the returned codes feed into other lookups (e.g. get_job). Usage is only implied by the tool name and the sample value.

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