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

Beyond the readOnlyHint and openWorldHint annotations, the description discloses a 5-minute cache, payment requirements, and the return structure with English and Korean original fields for verification. Does not contradict 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?

Well-structured with clear sections for purpose, pricing, returns, and arguments. Includes a single-sentence usage rationale. No unnecessary fluff, though the emoji-prefixed payment details could be considered slightly promotional but still relevant.

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?

Covers purpose, cost, cache, return fields, and parameter constraints. The existing output schema and annotations fill in remaining details. Missing explicit error handling or date-time specifics, but for a simple read-only news tool it is sufficient.

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 only parameter 'limit' is fully described in the schema (1-10, default 5). The description repeats the same information without adding extra meaning beyond what the schema already provides.

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?

Clearly states it provides Korean semiconductor industry news aggregated from Naver and translated to English, listing specific topics. Distinguishes from siblings like get_kr_news_kpop (different industry) and get_kr_news_semiconductor_summary (likely summary variant).

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?

Gives context that Korean chip news leads global semiconductor supply-chain signals, implying when this data is valuable, but does not explicitly name alternatives or provide when/when-not guidance relative to the summary sibling.

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