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

Because no annotations are provided, the description carries the burden of behavioral disclosure. The phrase 'Prompt discarded' clearly communicates that the tool ignores the input prompt, which is useful and non-obvious. It stops short of stating whether all seven parameters are ignored, but that is partially covered by the schema.

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 state the main action first and add the key caveat second. There is no filler.

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?

The core fact that it returns a fixed three-step template is present, and the schema covers the parameter names. However, no output schema exists and the description does not explain what the template looks like or explicitly say that no parameters are needed, so an agent has to infer invocation details.

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 seven parameters have descriptions in the schema, so the schema already carries the semantic load. The description adds only the generic 'Prompt discarded' line and does not clarify how the disparate parameters (URL, city, JSON, path) relate to a thinking template; this keeps it at the baseline rather than above.

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 concrete action ('Return') and a concrete resource ('three-step thinking template'), so an agent can understand the basic function. It does not detail what the template contains or how it differs from other tools, but the core purpose is not hidden.

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?

The description provides no conditions or alternatives for when to use think-steps instead of sibling tools such as validate-json, normalize-url, or weather-hint. It only says what the tool returns, not when to invoke it.

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