get_kr_sentiment

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

Annotations already indicate read-only and open-world behavior. Description adds pricing ($0.05 per call), caching (1-hour), and output details (sentiment label, score, report etc.). No contradictions.

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?

Concise with bullet-like structure. Front-loaded with main purpose. Could be slightly more structured but no unnecessary content.

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?

Provides important context including data sources, outputs, caching, and pricing. With an output schema present, the description covers key aspects adequately for a zero-parameter 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?

Zero parameters and 100% schema coverage. Description adds no parameter info, but baseline is 4 per guidelines. It does describe the output effectively.

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 is for Korean crypto market sentiment analysis in English. Distinguishes from sibling tools like get_kimchi_premium or get_kr_prices by focusing on sentiment and providing a first-in-world Korean-to-English API.

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?

Implies usage for sentiment analysis but does not explicitly state when to use it versus sibling tools like get_market_read or get_stablecoin_premium. No exclusions or alternatives are mentioned.

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