getForexShortQuote

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

Annotations already indicate read-only, idempotent, and open-world behavior. The description adds 'fast look' and 'live' but does not contradict annotations. No additional behavioral details provided 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?

Two sentences, no filler. Minor redundancy in first sentence ('Quickly access concise forex pair quotes' and 'Forex Quote Snapshot API').

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 snapshot tool with one parameter and annotations covering safety, the description is mostly complete. Lacks specification of response fields or difference from full quote, but not critical.

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?

Only one parameter (symbol) with full schema description coverage. The description does not add any meaning beyond the schema's 'Forex pair symbol (e.g., EURUSD)'. Baseline 3 applies.

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?

Clear verb ('access') and resource ('forex pair quotes'), with emphasis on speed and conciseness. However, does not explicitly differentiate from sibling tools like getForexQuote 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?

No guidance on when to use this tool versus alternatives (e.g., getForexQuote for detailed quotes, getForexBatchQuotes for batch requests). The description only states what it does, not when it's appropriate.

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