textokit_translate_es

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

With no annotations, the description carries the burden of disclosure and does deliver the critical operational facts: cost (0.003 USDC per call), payment rail (x402 on Base) and that it is charged from the caller's wallet. It does not describe the response shape or failure/refund behavior, so it stops short of full transparency.

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?

Three short clauses, front-loaded with the capability, then cost, then the free-sample escape hatch. Nothing is redundant or padded.

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 two-parameter, no-output-schema tool, the description covers purpose, dialect target, pricing model and a free alternative. Only the return format and input-handling edge cases are left unstated, which are minor at this complexity.

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?

Schema coverage is 100%, so both text and tone are already documented in structured fields; the description adds only the dialect nuance. Baseline 3 is appropriate since the schema does the heavy lifting.

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?

States a specific verb and resource ("translate to Spanish (Argentina)") plus a differentiating dialect constraint (rioplatense voseo) and scope (any source language). No sibling tool does translation, so an agent can select it unambiguously from the list.

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?

Usage is only implied: it names textokit_sample as a free trial path, which is a useful routing hint, but there is no explicit when-to-use vs when-not, nor guidance on picking a tone or handling unsupported inputs.

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