search_drugs_by_name

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It usefully adds that '이름이 유사한 의약품 여러개가 나올 수 있습니다' (multiple drugs with similar names may appear), which is important behavioral context about fuzzy matching. However, it doesn't disclose other behavioral traits like rate limits, authentication needs, error conditions, or what '대략적인 정보' (approximate information) specifically entails.

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 appropriately concise with two sentences that each serve a clear purpose: the first states the tool's function, and the second provides important behavioral context and alternative guidance. It's front-loaded with the core purpose and wastes no words, though it could be slightly more structured.

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 single-parameter search tool with no annotations and no output schema, the description provides adequate but incomplete context. It covers the purpose, behavioral nuance about fuzzy matching, and alternative tool, but doesn't explain what information is returned or any limitations. Given the complexity is low (one parameter), it's minimally viable but could better address output expectations.

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?

The schema description coverage is 100%, with the single parameter 'drugname' well-documented in the schema as '검색할 의약품의 이름 (영문 또는 한글)' (drug name to search, English or Korean). The description doesn't add any parameter-specific information beyond what the schema provides, so it meets the baseline of 3 for high schema coverage.

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 the tool's purpose: '약학정보원에서 의약품 이름으로 대략적인 정보들을 가져옵니다' (retrieves approximate drug information by name from the Pharmaceutical Information Center). It specifies the action (retrieve), resource (drug information), and source (Pharmaceutical Information Center). However, it doesn't explicitly differentiate from its sibling tool beyond mentioning it as an alternative for detailed information.

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 provides clear context for usage: it's for approximate information retrieval by drug name, with the note that similar-named drugs may appear. It explicitly mentions the alternative tool 'get_drug_detail_by_id()' for detailed information, giving good guidance on when to use each. However, it doesn't specify when NOT to use this tool or any prerequisites.

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