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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It states the tool retrieves data but omits details about rate limits, data freshness, error handling, or any side effects. The minimal description fails to convey important behavioral traits for an agent.

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 sentence that is front-loaded and efficient. However, it sacrifices detail for brevity, missing essential information. It earns its place but could be improved without adding much length.

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?

The tool has 5 parameters, no output schema, and moderate complexity. The description is too brief to guide an agent effectively; it does not explain default currencies, the structure of returned market data, or how boolean flags affect output. The agent would need additional knowledge to use this tool correctly.

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 description coverage is only 20% (only tokenId has a brief description). The tool description does not elaborate on parameters like vsCurrency, include24hChange, include24hVolume, or includeMarketCap. With low coverage, the description should compensate, but it adds no extra meaning beyond the schema.

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 'Get token price and market data from CoinGecko' clearly specifies the verb (get), the resource (token price and market data), and the source (CoinGecko). It distinguishes from sibling tools like coingecko_getOHLCV, which focuses on OHLCV data, and coingecko_getTokenInfo, which retrieves broader token 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 no guidance on when to use this tool versus alternatives such as coingecko_getTrending or coingecko_getTopGainersLosers. There is no mention of prerequisites, typical use cases, or scenarios where this tool is inappropriate.

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