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

The description discloses an important behavior: the prompt is discarded, meaning the tool does not depend on or persist the user's input. However, there are no annotations to cover side effects, permissions, or external calls, and the description does not clarify whether all nine schema parameters are similarly ignored or what the three-step template actually contains. It is partially transparent but not fully.

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. The first sentence states the core deliverable, and the second provides the key behavioral constraint. Every word earns its place, and the most important information is 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?

For a tool that returns a fixed template, the description is minimally adequate: it states the output and that the prompt is discarded. But with 9 optional parameters, no output schema, no annotations, and 27 sibling tools, an agent would benefit from knowing that parameters are effectively ignored, when this tool is the right choice, and what the three-step template looks like. The description leaves those gaps.

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 schema already documents each parameter individually. The description adds only the high-level 'Prompt discarded' note, which is useful but does not map to the nine parameters or explain how they relate to the returned template. Baseline 3 is appropriate because the schema carries the parameter-semantics burden.

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 clearly states the action ('Return') and the deliverable ('a three-step thinking template'), so an agent knows what the tool produces. It does not name or differentiate from siblings, but none of the listed siblings obviously overlaps with returning a thinking template. The second sentence, 'Prompt discarded,' adds an important qualification.

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 explicit guidance about when to use this tool versus alternatives, and no mention of when not to use it. 'Prompt discarded' implies the input is not used, but the description does not explain a scenario like 'use this when you need a fixed reasoning scaffold' or 'do not use this for stateful thinking.' With 27 sibling tools, this lack of routing guidance is a notable gap.

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