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

With no annotations, the description carries the full burden and does so well: it discloses that the data is unmistakably fake, that nothing is written, and that nobody is contacted. It also specifies how the output should be presented, including card order, score, and the plain-English 'why' line.

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 front-loaded with the core purpose and usage trigger, then adds only operationally useful display instructions and safety notes. Every sentence contributes something an agent needs.

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 no-annotation, no-output-schema tool, the description is complete: it explains what the sample contains, how fake the data is, how to present the results, and what side effects do not occur. An agent has enough context to call and present it correctly.

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?

There is only one parameter, n, and the schema already documents its range and default with 100% coverage. The description adds no parameter-specific meaning beyond the schema, so the baseline 3 applies.

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 specific verb and resource: showing a sample of Nuvidian P1's 'Today's 10' deck. It also scopes the content as fictional Florida agents deliberately built as a pre-signup demo, which implicitly distinguishes it from real-practice siblings like p2_practice_today.

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 gives explicit trigger phrases: call it when someone asks 'what is P1?' or 'show me'. It does not name alternatives such as describe_product or p2_practice_today, so the when-not/alternative routing is implied rather than stated.

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