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

No annotations are provided, so the description carries the full burden, yet it discloses nothing about the report format, what sections it contains, whether it is deterministic, or how the two inputs are consumed. 'Generate a text report' tells the agent nothing operationally useful.

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?

It is a single short sentence and front-loaded, so there is no padding, but the brevity stems from under-specification rather than efficient communication. A tight sentence still has to convey purpose, and this one barely does.

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 two-parameter tool with no annotations and no output schema, the description should explain behavior, expected input shape, and output format. It does none of these, leaving the agent unable to predict what the call will return.

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 description coverage is 100%, so per the rules the baseline is 3. However, the schema's own descriptions ('Text to process', 'Input to process') are near-meaningless, and the description adds no clarification of how 'text' differs from 'input' or which one is expected.

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 largely restates the tool name: 'Text Report: Generate a text report from data.' It does contain a verb ('Generate') and a resource ('text report'), but 'report' and 'data' are generic, and nothing distinguishes it from siblings like x402-report, x402-number-report, or x402-text-stats.

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, when not to, or which siblings (x402-report, x402-text-stats, x402-summarize) it replaces. An agent gets no selection criteria whatsoever.

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