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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. Beyond that the description adds essentially nothing behavioral: it does not say what the five modes actually change, what the optimized output looks like, or any latency/limit characteristics.

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?

A single front-loaded sentence with no filler or repetition. It is efficient, though the triple list 'rough ideas, drafts, and concepts' is mildly redundant and could be tighter.

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?

There is no output schema, so the description carries the burden of describing what comes back; it never does, nor does it explain the mode options that materially change behavior. For a tool whose entire value is a transformed prompt, an agent is left guessing about the return shape.

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% and there are only 2 parameters, so the schema already documents both. The description adds no meaning to 'mode' (its five enum values remain unexplained) or to the required 'prompt' field, 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 gives a concrete verb ('Transforms') and a clear input/output framing (rough ideas, drafts, concepts -> production-ready AI prompts), so the purpose is unambiguous. However, it never differentiates itself from the sibling generatePrompt, so an agent cannot tell which of the two to pick from the text alone.

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 when-to-use guidance, no prerequisites, and no mention of the sibling generatePrompt as an alternative. The phrase 'creative and technical workflows' gestures at domains but does not tell the agent when this tool is the right choice versus generatePrompt.

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