get_kr_news_kpop

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

Annotations include readOnlyHint and openWorldHint, and the description adds behavioral details: '5-min cache,' payment info ($0.01 per call, x402 micropayment), and return structure. No contradiction with annotations.

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 moderately concise, with first sentence stating main purpose, then additional context (caching, payment, docs). Could be slightly more concise but effective overall.

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?

Given the tool is simple with one parameter and an output schema exists, the description explains return fields and caching. Payment details are included. No major gaps for a read-only news tool.

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?

Only one parameter 'limit' with schema description 'Number of articles to return (1-10)' covering 100%. The description adds no further semantics beyond the schema, so baseline score is appropriate.

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 it retrieves Korean K-pop news aggregated from Naver, translated to English, with AI relevance classification, and specifies the types of news (artists, groups, etc.). It distinguishes from sibling tools like get_kr_news_semiconductor and get_kr_news_kpop_summary.

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 usage context: 'Korean entertainment news often moves global fan markets before English coverage,' implying when to use for early K-pop news. However, it does not explicitly state when not to use or compare with alternatives like get_kr_news_kpop_summary.

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