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

With no annotations, the description carries the behavioral burden. It does disclose one important trait: the prompt is discarded, meaning the output is not customized. However, it does not clarify whether the optional parameters are ignored or how the returned template is structured, leaving notable behavioral gaps.

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?

Two short sentences, no filler, and the core purpose is front-loaded. Every word contributes, making this an appropriately concise definition for a simple template-returning tool.

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?

Despite 9 optional parameters and no output schema, the description does not explain how to invoke the tool or what to pass. It never states that no arguments are needed or that the template is fixed, so an agent may be unsure whether to populate parameters like 'url', 'city', or 'path'.

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 the baseline is 3. The tool description adds no parameter-level meaning beyond the schema. The description 'Prompt discarded' is too broad to clarify which of the nine optional parameters are relevant.

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 action and deliverable: 'Return a three-step thinking template.' This is enough to identify what the tool does. It is somewhat vague about the template's content, and it does not explicitly compare to sibling tools, so it misses the top score.

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 think-steps versus the many sibling tools. 'Prompt discarded' hints that the tool ignores the request, but it does not state when an agent should select this tool or when it should not.

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