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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It reveals a cost ('pago x402 $0.6 USDC') but does not explain whether the tool executes code, what output format is returned, whether it calls external systems, or what side effects may occur. This is minimal insight for a tool with no annotation support.

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 very short and front-loaded with the core action. However, it is under-specified rather than efficiently complete. The payment detail may be relevant, but several important elements are missing, so the brevity is not a strength.

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 one-parameter tool, the description still leaves too much unstated: what language or type of snippet, how the input should be phrased, what output the agent should expect, and how the payment affects invocation. The presence of an output schema could reduce this burden, but none exists.

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 one parameter, 'input', with no description and 0% schema description coverage. The tool description does not explain what should go in 'input' beyond an implied request for a snippet. With such low schema coverage, the description was expected to compensate, and it does not.

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 clear verb and resource: 'Escribir un snippet o script pequeno'. It is not a tautology and gives the agent a basic sense of the tool's purpose Among the siblings, this is the only one obviously aimed at writing code snippets, though it does not explicitly distinguish itself from content-generation tools like copy_corto.

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?

There is no guidance about when to use this tool versus alternatives. The description only mentions the write action and a payment, but no context, conditions, exclusions, or preferred use cases. An agent must infer that this tool is appropriate for code-generation requests.

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