cmc_quotes

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

The annotations already declare read-only, open-world, idempotent, and non-destructive behavior, so the safety profile is clear. The description adds only the CoinMarketCap source context; it does not describe authentication needs, rate limits, return shape, or how multiple symbols are handled.

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 definition is a single front-loaded sentence with no filler. It is appropriately concise for a simple quote-fetching tool, though its brevity contributes to the missing usage and parameter context elsewhere.

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?

With four undocumented parameters, 0% schema coverage, and no output schema, the description should carry more detail than it does. It does not explain how to call the tool, what combination of id/symbol/convert is valid, or what a caller should expect back.

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 0%, and the description does not explain any of the four parameters. It does not clarify id versus symbol, what convert does, or how api_key should be supplied, so it fails to compensate for the absent schema documentation.

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 states a clear verb and resource: get cryptocurrency quotes from CoinMarketCap. It is understandable on its own, but it does not differentiate this tool from sibling crypto tools such as cmc_listings, cmc_info, or crypto_price, nor does it clarify whether quotes are for one coin or many.

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?

There is no guidance on when to use this tool versus alternatives. The description does not mention when cmc_quotes is preferable to cmc_listings, cmc_info, cmc_trending, or crypto_price, and it provides no prerequisites or exclusions.

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