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

No annotations are provided, so the description carries the full burden. It explicitly states the operation is retrieval ('가져온다') and lists the specific information returned (introduction, category, official site, operational status, reviews), adding useful behavioral context about the return content. It does not mention error cases or side effects, but for a read tool this is adequate.

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 a single, front-loaded sentence that clearly states the action and the information scope. Every word earns its place with no redundancy.

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 tool with one parameter and no output schema, the description lists the return categories, which is sufficient to set expectations. It does not detail error responses or exact structure, but that is not critical for such a straightforward get operation.

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% and the parameter description ('search_korean_saas 가 반환한 slug') already explains the parameter meaning. The tool description adds no additional parameter semantics, so the baseline score of 3 applies.

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 clearly states what the tool does: it retrieves detailed information (introduction, category, official site, operational status, reviews) about a specific Korean SaaS. The verb '가져온다' (retrieves) and the resource '특정 한국 SaaS' are specific, and the tool is distinct from siblings like search, compare, and list.

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 usage after identifying a specific SaaS, but it does not explicitly state when to use it versus siblings. The parameter schema hints that the slug comes from search_korean_saas, but this is not in the description. There is no mention of alternatives or exclusions.

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