TDQS

A3.9/5.0
Behavior4/5

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

Annotations provide readOnlyHint and openWorldHint, covering safety and open-world assumptions. The description adds the key behavioral rule: if no exchange rate exists for the exact date, the closest available date before is used. This is a useful disclosure beyond the annotations. No contradiction found.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences with no fluff. The first sentence states the primary purpose, and the second adds a critical fallback rule. Information is front-loaded and every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description does not explain the return format (e.g., whether it returns the converted amount as a number or an object). It also doesn't address edge cases like when no historical rate exists at all. The fallback rule is covered, but the missing output details and potential error scenarios leave gaps for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All four parameters have schema descriptions (100% coverage), so the schema carries the parameter documentation. The description does not add extra meaning beyond what the schema provides (e.g., it mentions 'specific date' but the schema already defines the format). Baseline 3 is appropriate given full schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear action: 'Convert an amount from one currency to another using the exchange rates for a specific date.' It specifies the resource (currency conversion), the scope (specific date), and the fallback behavior (closest available date before). This differentiates it from convert_currency_latest and other siblings without needing to inspect schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for date-specific conversions but does not explicitly contrast with alternatives like convert_currency_latest or get_historical_exchange_rates. It lacks explicit 'when to use' or 'when not to use' guidance, though the specific-date scope is clear. This is implied rather than stated.

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