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 fails entirely: it does not say whether the tool mutates data, requires authentication, returns a specific format, or has any side effects. The only disclosed fact is a payment rate, which is not a behavioral trait of the tool's operation.

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 short but not concise in a helpful sense. It wastes the single sentence on meta-information (creation origin and pricing) instead of the tool's purpose. It is under-specified, not efficient, and lacks any front-loaded functional statement.

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?

Despite having only one parameter and no output schema, the description is completely inadequate. Even for a simple tool, an agent needs to know what the tool does, how to phrase the input, and what kind of output to expect. This description provides none of that, making the tool effectively unusable without external knowledge.

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 description coverage is 100% but only because the parameter 'input' is described as 'entrada', which is a tautological synonym. The description adds zero semantic value about the expected format, content, or constraints of the input. For a tool that presumably rewrites text, the agent has no clue what kind of input is acceptable.

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 does not state what the tool does. It only mentions that it was auto-created from demand and its pricing, which is irrelevant to its function. The name 'reescribir-formal' hints at rewriting text formally, but the description itself gives no indication of the tool's purpose, leaving the agent to guess.

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. The description does not mention any context, prerequisites, or distinctions from sibling tools like 'corregir' or 'traducir'. An agent would have no idea whether to pick this over other rewriting or correction tools.

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