getForexQuotes

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

Annotations already declare this as a read-only, idempotent, open-world operation. The description adds that it returns 'real-time price changes and updates', which is consistent. However, it does not disclose potential limitations such as rate limits, the number of pairs allowed, or data freshness beyond 'real-time'. It does not contradict 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?

The description is two sentences long and front-loaded: it immediately states the core action and resource. Every sentence adds value without redundancy. No wasted words.

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?

Given the lack of an output schema, the description should hint at return fields (e.g., bid, ask, price, change). It mentions 'price changes and updates' but is vague. The single parameter 'short' is not explained in the description. For a low-complexity tool, it is functional but could better prepare the agent for response handling.

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 input schema has one parameter ('short') with a description in the schema itself, achieving 100% coverage. The tool description does not add any additional meaning or context about the parameter (e.g., what 'short format' means or how it affects output). Baseline 3 is appropriate as schema already documents it.

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 it retrieves real-time quotes for multiple forex pairs in a single batch request. It uses specific verbs and resources ('Retrieve real-time quotes') and distinguishes from siblings like getForexQuote (single pair) by emphasizing 'multiple' and 'batch'. However, it could be more precise about what fields are returned (e.g., bid, ask, price).

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 batch usage but does not explicitly state when to use this tool versus alternatives like getForexQuote or getForexBatchQuotes. No when-to-use or when-not-to-use guidance is provided, and no alternative tools are mentioned despite many available (e.g., getForexQuote, getForexShortQuote).

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