textokit_dolar_ar

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

With no annotations, the description must carry the full behavioral burden. It discloses cost (0.002 USDC per call via x402 on Base) and a free sample alternative, which is valuable. However, it omits important behavioral details such as which dollar rates are included (official, blue, etc.) and the return format.

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 highly concise and front-loaded with the core resource, followed by cost and a sample alternative. Every sentence is informative and there is no waste.

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 simplicity (no parameters, no output schema), the description covers the essentials of purpose and cost but lacks details about the specific data returned (e.g., whether it includes historical rates or multiple dollar types) and usage context, leaving gaps for an agent to infer.

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?

There are zero parameters, so the baseline is 4. The description does not need to explain parameter semantics, and it appropriately focuses on other aspects.

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 resource: 'Argentina dollar exchange rates'. While it lacks a verb like 'get' or 'retrieve', it clearly identifies the data provided and distinguishes itself from more general siblings like textokit_fx_rates by its Argentina-specific focus.

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 usage for Argentina dollar rates and points to a free sample alternative (textokit_sample), but it does not explicitly state when to use this tool versus alternatives like textokit_bcra_indicadores or textokit_fx_rates. There are no exclusions or conditions given.

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