getForexShortQuote

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

The annotations already establish read-only, idempotent, and open-world behavior, so the description does not need to repeat safety details. It adds some useful context by saying the data is live/real-time and includes price changes and volume, but it does not mention data freshness constraints, rate limits, authentication needs, or market-hour behavior.

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 short and front-loaded, quickly establishing the purpose and returned data categories. It has some redundancy between 'Quickly access' and 'fast look' and includes the API product name, but it remains efficient overall.

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 single-parameter quote tool with full schema coverage and helpful annotations, the description provides enough context to call it correctly. It also compensates for the lack of an output schema by naming the main returned data categories: exchange rates, price changes, and volume.

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 description coverage is 100%, and the single required parameter is already documented with the expected forex pair format example. The description does not add syntax, case-sensitivity, or symbol-validation details beyond what the schema provides, so the baseline score of 3 is appropriate.

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 a specific action and resource: accessing concise forex pair quotes with live exchange rates, price changes, and volume. It is clear enough to understand the tool's basic function, but it does not explicitly distinguish it from siblings like getForexQuote, getForexQuotes, or getForexBatchQuotes.

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 implies a quick or snapshot use case through phrases like 'Quickly access' and 'fast look,' but it gives no explicit when-to-use guidance, prerequisites, or alternatives. It does not tell an agent when to choose this tool over getForexQuote, getForexQuotes, or getForexBatchQuotes.

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