get_benefit_detail

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The description adds no operational traits such as permissions, rate limits, or error behavior beyond the annotated safety profile; it mainly enumerates returned content, which the output schema likely covers.

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 short and front-loaded: the purpose and returned field list come first, followed by a clear Args section. The field enumeration is somewhat long but informative and not padded with filler.

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 one-parameter, read-only detail tool with an output schema and safety annotations, the definition is nearly complete: it identifies the resource, lists the detail content, and tells where to obtain service_id. It could be improved by explicitly routing eligibility questions to check_eligibility, but nothing essential for calling it is missing.

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%, so the description must compensate. It does add meaningful semantics for the single required parameter by specifying that service_id should be taken from find_benefits/search_benefits results. It does not define the ID's format or constraints, keeping it below a 5.

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?

States the resource ('혜택 상세') and enumerates the specific detail fields returned (지원대상, 선정기준 원문, 지원내용, 신청방법, 구비서류, 문의처, 온라인 신청 링크, 코드화된 자격조건). This clearly separates it from search/list siblings, though it does not explicitly name an alternative.

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 Args line says service_id comes from find_benefits or search_benefits results, which implies use after a search step. However, it does not explicitly state when to use this tool versus check_eligibility or other siblings, nor does it include exclusions.

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