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

No annotations are present, so the description carries the full disclosure burden. It does reveal that the prompt is discarded, but it says nothing about whether the eight parameters are ignored, whether the template can vary, or what the output looks like. This is minimal disclosure for a tool with multiple inputs.

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 description is two short sentences with no filler words, making it highly efficient. However, the brevity leaves behavioral and usage questions unanswered, so conciseness comes at the cost of completeness. Still, the wording is well-structured and front-loaded.

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?

Given the tool's eight parameters and the large sibling set, this description is too sparse. It does not explain what the three-step template actually is, how an agent should use the result, or why this tool exists among similar-looking tools. There is no output schema, so the return value is underspecified.

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?

All eight parameters are fully described in the input schema, including the fact that each is used only for a shape check and then discarded. The description adds no additional parameter meaning, but the schema already covers this comprehensively, 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 states a clear action ('Return') and a specific resource ('a three-step thinking template'), which is enough to understand the basic purpose. However, it does not distinguish the tool from siblings or clarify what the template contains, and 'Prompt discarded' adds ambiguity about how inputs are used.

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 versus any of the many sibling tools. No conditions, prerequisites, or alternatives are mentioned. The only contextual hint is 'Prompt discarded,' which does not help an agent decide when this tool is appropriate.

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