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

No annotations provided, so description alone must disclose behavior. It mentions return fields (rate, change, etc.), cost, and example. However, it does not discuss auth requirements, rate limits, or error handling, which are relevant for a read tool.

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?

Very concise with clear sections (purpose, when to use, returns, cost, example). Every sentence provides value, no redundancy.

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 one-parameter tool with no output schema, the description fully covers purpose, usage, return structure, and cost. It is complete for the complexity level.

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?

Input schema is 100% covered with good description. The tool description adds context: 'No arguments returns all major pairs; pass a pair code for a single rate.' This reinforces schema meaning.

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 states 'Get current foreign exchange rates' with clear verb and resource, and distinguishes from siblings by focusing on FX market data. It specifies scope: all major pairs vs single pair.

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?

Explicitly says 'WHEN TO USE: For currency exchange rates and FX market data.' Includes example and cost. While it doesn't explicitly exclude alternatives, the context is clear among financial data siblings.

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