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

No annotations are provided, so the description carries the full burden. It does disclose a real behavioral trait the agent needs: the tool is metered, costing 0.05 USDC on Base per use via x402. However, it says nothing about output form, latency, or failure/auth behavior under the payment scheme.

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 tight sentence plus a bracketed cost note; the core purpose is front-loaded and every clause carries information. Slightly dense/telegram-style rather than prose, but no waste.

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 generator with no output schema, explaining the input shape and the payment model covers the essentials. Missing are any differentiation from sibling pitch tools and any indication of what the returned pitch looks like, which leaves gaps an agent would have to guess at.

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?

Schema coverage is nominally 100%, but the actual schema is an opaque single string 'input' described only as 'service input'. The description supplies the real structure the agent must send: {producto, audiencia?, duracion_seg?}, including which fields are optional. That is genuine added meaning, though it conflicts slightly with the schema's declared string type.

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?

States a specific verb and resource: 'Genera un elevator pitch estructurado' tells the agent exactly what artifact is produced. It does not distinguish itself from nearby siblings such as 'investor-pitch' or 'investor-deck-copy', so it is clear but undifferentiated.

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 statement of when to choose this tool over 'investor-pitch' or other pitch-adjacent siblings. The optional/required markers on the input fields hint at caller obligations but give no usage context.

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