get_forex_quote

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint. Description adds that it covers 'major currency pairs' and behavior when pairs empty. No contradictions, and adds value beyond annotations.

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?

Description is short, with first line summary, strategy tag, example, and parameter description. Every sentence is purposeful, well-structured, and efficient.

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?

With one optional parameter, rich annotations, and an output schema indicated, the description covers purpose, usage strategy, and parameter behavior. No missing critical information for selection and invocation.

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% description coverage. Description explains 'pairs: Currency pairs (optional; empty = all)' and includes example with format 'USD/CNY'. This adds meaning beyond schema type, though format specifics could be more detailed.

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?

Description clearly states 'Get forex quote for major currency pairs', with a specific verb and resource. Among siblings like get_quote, get_futures_quote, it distinguishes itself for forex/currency pairs, making selection unambiguous.

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?

Strategy tag and example provide explicit guidance: 'Leave pairs empty for all major pairs.' This tells when to omit the parameter. No explicit distinction from similar get_exchange_rate, but context is clear.

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