get_commodity_price

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

No annotations provided, so description carries full burden. Only states 'Get' indicating a read operation, but no details on side effects, authentication, rate limits, or return behavior. Minimal behavioral disclosure.

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?

Single concise sentence with examples. No filler or redundancy. Front-loaded with verb and resource.

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?

Despite simplicity, the description lacks any explanation of what is returned (e.g., current price, change, etc.). No output schema and no annotations, so description should cover more. Incomplete for an agent to understand full behavior.

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 has 0% coverage, but description gives three example values (GC=F, SI=F, CL=F) which adds meaning. However, it doesn't explain the default, accepted values, or format. Partially compensates for schema gap but not fully.

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 'Get commodity price' with specific examples (Gold, Silver, Crude) and tickers, making the purpose unambiguous. It effectively distinguishes from siblings like 'get_spot_price' by focusing on these specific commodities.

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 explicit when-to-use vs alternatives. However, the examples imply usage for those specific commodities, and the tool is simple. Lacks guidance on when not to use or relation to other price tools.

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