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

No annotations are present, and the description does not disclose return format, side effects, error behavior, or whether inputs are actually ignored. Several parameters are described as 'discarded', but the overall behavior remains opaque.

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 text is short, but it omits essential structure and includes a confusing 'Prompt discarded' fragment. Brevity is not used to clarify the tool's contract.

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?

With no output schema, no annotations, 9 ambiguous parameters, and no usage context, the description is far too incomplete for an agent to invoke 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?

The schema has 9 optional strings, each with a description, but those descriptions are unrelated to a 'thinking template' and repeatedly mention 'discarded after...' without explaining how the value affects the tool. Callers cannot determine which, if any, parameters matter.

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 says 'Return a three-step thinking template', which names an output, but 'Prompt discarded' is cryptic and no context is given for what the template is or how to invoke it. The purpose remains vague relative to the 9 unrelated optional parameters.

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 guidance is given on when to use this tool, what inputs are needed, or how it differs from sibling tools. 'Prompt discarded' is not an actionable usage instruction.

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