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

No annotations are provided, so the description carries full burden. It does disclose real behavioral traits beyond structure: the pricing model (x402, 0.01 USDC on Base, pay-per-use). But it omits other relevant traits such as what the generated scenarios look like, any rate limits, or auth needs.

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 sentence is one run-on that is left grammatically unfinished ('que el usuario') and has payment metadata bolted on mid-flow in brackets. The 'Auto-created from research:' prefix is noise and the purpose is not cleanly front-loaded or terminated.

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 simple one-argument tool with no output schema, the description gives enough of a trigger and input hint to attempt a call. But the truncated sentence and the absence of any output framing or sibling differentiation leave the definition only minimally viable.

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 single parameter is named 'input' with the useless schema description 'entrada', so the schema itself does not do the heavy lifting. The description compensates by indicating the input should contain a dilemma plus a model's recommendation, which adds real meaning about what to pass. Coverage is nominal rather than substantive.

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 names a specific action (generates alternative scenarios and options) and a trigger (given a dilemma and a model's recommendation), so the resource is identifiable. However, the sentence is syntactically broken and truncated ('...opciones alternativas que el usuario'), and it is surrounded by near-identical siblings (future-expander, future-options-expander, futures-broadener, futures-spectrum-expander, future-widener, horizon-expander) with no signal to distinguish this one.

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?

It offers a partial trigger condition ('dado un dilema y la recomendacion de un modelo'), but never states when to use this tool versus the many sibling expanders/broadeners, nor any exclusions or prerequisites. An agent cannot route between this and future-expander/futures-spectrum-expander from the text.

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