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

Since no annotations are provided, the description carries full behavioral burden. It notes the tool is powered by Fusebox SDK TradeModule and implies a read-only operation with 'Returns'. However, it does not disclose potential side effects, authentication needs, rate limits, or what happens if the token is not tracked.

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 two sentences with no redundant information. The key purpose and a distinguishing detail (tracked tokens) are front-loaded. Every sentence earns its place.

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 read operation with one parameter and no output schema, the description covers the core purpose and a relevant constraint. However, it could be more complete by specifying the return value format (e.g., decimal, string) or clarifying that it returns the price in USD.

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 only parameter, tokenAddress, has a clear schema description. The description adds value by specifying that only tokens tracked by Fusebox are supported, which is extra context 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 clearly states the tool returns the current USD price for an ERC-20 token tracked by Fusebox. The verb 'Returns' and resource 'USD price for an ERC-20 token' are specific. It distinguishes from sibling tools like fuse_get_token_price_history and fuse_get_token_price_change, which deal with historical or change data.

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. It does not mention that it is only for current prices, nor does it reference sibling tools for history or changes. The user must infer usage context from the name alone.

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