market_coingecko_simple_price

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

No annotations are provided, so the description must carry the full burden. It only states a basic read operation with no disclosure about rate limits, return format, pagination, or authentication. This is minimal transparency for a tool with no structured behavioral hints.

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, focused sentence that clearly communicates the core function. No wasted words, front-loaded with action and resource, and the parenthetical adds a relevant tip ('most efficient for price lookup').

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 simple price lookup tool with a well-documented schema, the description is minimally adequate. However, it lacks context on when to use it among many similar market tools, and there is no output schema to clarify the return structure. The description could be more complete for an agent selecting among close alternatives.

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 100%, so the baseline is 3. The description adds no additional meaning beyond what the schema already provides for parameters like ids, vsCurrencies, and the include flags. It does not harm, but also does not enhance.

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 clearly states the tool gets current prices for multiple coins in multiple currencies, using a specific verb ('get') and resource ('current price of coins in multiple currencies'). It broadly differentiates from other market tools by emphasizing efficiency, though it does not explicitly name sibling tools or contrast with them.

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 phrase 'most efficient for price lookup' implies a use case, but the description does not specify when to prefer this tool over alternatives like market_coingecko_coins_markets or market_get_multiple_prices. No exclusions or scenarios are mentioned.

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