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

Annotations are absent, so the description must carry behavioral disclosure. It reveals a payment requirement ('pago x402 $1.2 USDC') and the pandas implementation, which are useful. However, it does not state whether the operation is read-only, what it returns, or any data-handling constraints.

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 a single front-loaded sentence with no filler. The core action and resource appear first, and the payment detail is appended compactly.

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 with no annotations or output schema, the description should specify what 'input' should contain and what result to expect. It only provides the action and cost, leaving critical invocation details missing.

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 undocumented 'input' parameter with 0% coverage, and the description only loosely suggests the input is a 'dataset'. It does not clarify whether input is a file path, CSV content, an ID, or something else, so the agent is left guessing about the required string format.

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 action ('Analizar') and resource ('un dataset con pandas'), so an agent can tell this is a data-analysis tool. It does not explicitly differentiate it from siblings like resumen or extraccion_datos, but the pandas/dataset framing makes its purpose reasonably distinct.

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 on when to use this tool versus alternatives such as resumen, grafico, or reporte. The description implies general dataset analysis but gives no conditions, exclusions, or routing hints.

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