Get Cryptocurrency Price

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

With no annotations, the description carries the full burden of behavioral disclosure. It only reveals that this is a read-only price lookup from CoinGecko; it does not mention potential external API latency, rate limits, error behavior, freshness, or return format.

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, well-structured sentence with no filler. Every word contributes: it names the action, the object, the tense ('current'), and the data source.

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 two-parameter read operation the description states the core purpose and source, and the return value ('price') is implied. Still, without an output schema or any parameter documentation, the agent must guess at ID conventions and the response shape, leaving the overview incomplete.

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 coverage is 0% and the description does not explain either parameter. 'cryptocurrency' hints at crypto_id, but the `currency` parameter is never mentioned and no formats, examples, or allowed values are given, so the description fails to compensate for the schema gap.

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 identifies the operation ('Get'), the target ('current price of a cryptocurrency'), and the source ('from CoinGecko'). It is specific and unambiguous, but there are no sibling tools to differentiate against, so it does not reach the top tier that requires distinction from 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?

The phrasing 'current price' implies the tool is appropriate when a current, CoinGecko-sourced price is needed. However, it never states explicit when-to-use conditions, prerequisites, or situations where an alternative approach should be chosen.

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