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

No annotations exist, so the description carries the full burden. It does disclose a meaningful behavioral trait — the x402 payment model (0.01 USDC on Base, pay-per-use) — which is genuine value, plus the provenance note. It says nothing about permissions, latency, or what a call consumes beyond the fee.

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?

One sentence, front-loaded with the action, which is good. But it is padded with bracketed pricing metadata and an "Auto-created from research" prefix that dilutes the core 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?

For a single-input generative tool with no output schema and no annotations, the description gives the gist of the transformation and the cost, but omits any sense of the generated output's form or volume. Minimally viable rather than complete.

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?

One parameter with the schema describing it only as "entrada". The description adds real meaning by saying the input is a decision plus an AI recommendation, but it never explains how the two should be combined or formatted into the single string. Marginal gain over a thin schema.

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?

It states a specific verb and resource ("genera escenarios y alternativas" from a decision plus an AI recommendation), so the action is intelligible. However, with seven near-identical siblings (future-expander, futures-broadener, horizon-expander, futures-spectrum-expander, future-options-expander, futures-divergence-expander, option-expander), the definition does nothing to distinguish itself from the pack, which is exactly where an agent needs help.

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?

"Dada una decisión y la recomendación de una IA" hints at the input context, but there is no when-to-use statement, no when-not-to-use, and no pointer to any of the interchangeable sibling tools. An agent has to guess.

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