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

No annotations are present, so the description carries the full burden of behavioral disclosure. 'Prompt discarded' hints that input is ignored, but the tool silently accepts nine parameters and the description does not state whether the call has side effects, requires auth, or returns a static vs dynamic template. The terse phrase is not enough.

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 two sentences are exceptionally short and front-load the main action, but 'Prompt discarded' is an ambiguous fragment. The description is under-specified rather than efficiently complete, so it earns only a middling score.

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 nine documented parameters and no output schema, the description should clarify whether the params are merely accepted or actually affect the result, and what form the three-step template takes. It only says the prompt is discarded, leaving critical calling context missing.

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 documents every parameter individually, so the description does not need to add parameter-level detail. It does add a global hint that input is discarded, but this is vague and does not tell the agent which of the parameters, if any, affect the returned template.

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 names a specific verb and deliverable ('Return a three-step thinking template'), so an agent understands the core action. However, it does not explain how this differs from sibling tools beyond the distinctive name, and 'Prompt discarded' adds ambiguity rather than clarifying scope.

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 about when to choose think-steps over alternatives such as geo-hint or validate-json, and there are no exclusions or preconditions. The only implied context is that a thinking template is wanted, which is too thin to guide selection.

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