calc_currency_estimate

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

No annotations are provided, so the description must be self-sufficient. It discloses 'rough rate' but fails to explain the source, reliability, or any side effects. The behavioral impact is minimal, but details are missing.

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?

A single, succinct sentence of 8 words. Every word is necessary and there is no superfluous content. It is efficiently front-loaded.

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 estimation tool, the description covers the basic purpose but omits important context like return format, data freshness, or whether it uses live rates. Given no output schema, these details would be beneficial.

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 schema has 0% description coverage, and the description adds no parameter explanations. While parameter names ('amount', 'from', 'to') are self-explanatory, the description does not compensate for the lack of schema documentation.

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 estimates currency conversion using a rough rate. The verb 'estimate' and phrase 'rough rate' distinguish it from precise converters like exchangerate_convert.

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 use for rough estimates but lacks explicit when-to-use or when-not instructions. Context from sibling names suggests alternatives, but the description itself does not guide selection.

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