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 reveals nothing about what the tool actually does, whether it's a rewrite, a scoring pass, or a transformation, or what the output looks like. 'Improve' is undefined behavior.

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 short front-loaded sentence with the tool name and purpose. No padding, though it's arguably too terse given the complexity of the underlying ambiguity.

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 tool whose entire value proposition (what 'optimize' means, how text and prompt interact, what is returned with no output schema) is unexplained, the description is inadequate. An agent cannot call this correctly without guessing.

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 100% but the only two parameter descriptions are 'Text to process' and 'Prompt to process' – near-vacuous labels that don't explain which parameter is the prompt to be optimized versus supplementary text. The description adds nothing to disambiguate these two overlapping params (both optional, zero required).

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 verb+resource ('Improve your AI prompts') which is clear in isolation, but among hundreds of AI-prefixed siblings (ai-rewrite, ai-grammar, ai-summarize, prompt-templates) it gives no signal about what 'optimize' means or how it differs. An agent cannot reliably distinguish it from sibling AI-text tools.

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?

No when-to-use context, no alternatives named, no exclusion criteria. With ~500 siblings the routing burden is high and the description offers no help in selecting this tool over x402-ai-rewrite or x402-prompt-templates.

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