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

With no annotations provided, the description must fully disclose behavioral traits. It partially does by listing the data categories returned, but it does not mention return format, response size, potential latency, rate limits, or implications of the boolean toggles. The description adds little beyond what the tool name suggests.

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 concise sentence that front-loads the key information (verb and resource) and lists the data categories without wasted words. It earns every word and is easy to scan.

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?

For a tool with seven parameters and no output schema, the description gives a useful overview of the response contents but lacks guidance on use cases, trade-offs, or how it relates to alternative endpoints. It is minimally adequate but leaves the agent without advice on when to choose this over more specific CoinGecko tools.

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 schema has 100% description coverage for all seven parameters, so the description does not need to add much. It does provide a high-level grouping of data categories that maps to the boolean parameters, but it does not add new meaning beyond the schema. Baseline 3 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 uses a specific verb 'Get' with a clear resource 'detailed coin data' and enumerates the included categories (description, links, market data, community data, developer stats). This distinguishes it from more specialized CoinGecko tools like simple price or chart endpoints, though it does not explicitly name any sibling alternatives.

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?

No guidance is provided on when to use this tool versus other CoinGecko tools such as market_coingecko_simple_price, market_coingecko_coin_history, or market_get_coin_by_id. The description lacks context for when a comprehensive data pull is preferred over more targeted queries.

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