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

With no annotations, the description carries the behavioral burden, and it does disclose that the prompt is discarded, which is a useful trait. However, it does not say whether the nine schema parameters are also ignored, whether the call is free of side effects, or what happens if arguments are supplied.

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, front-loads the main function, and each sentence earns its place: one states the deliverable, one discloses an important behavior. There is no filler or repetition.

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?

There are no annotations and no output schema, yet the description never explains the three steps or shows an example call, and the large 9-parameter input schema is left unexplained and appears to conflict with 'Prompt discarded.' For a tool with this schema richness, the description is too thin for an agent to invoke with confidence.

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% and all parameters are optional, so the baseline applies; the description adds only 'Prompt discarded,' which is more about the prompt than the nine listed parameters. The description does not reconcile why think-steps exposes parameters for ref/url/city/etc. if the prompt is discarded, leaving the agent unsure whether any argument is meaningful.

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 uses a clear verb and object ('Return a three-step thinking template') and adds that the prompt is discarded, which clarifies it is not a prompt-processing tool. It is distinct from the sibling tools by its deliverable, though it never says what the template is for, so it stops short of a 5.

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 statement of when to call this tool versus a sibling, and no 'when not to use' guidance beyond the terse 'Prompt discarded.' The intended trigger—user wants a three-step thinking template—is only implied by the name and return value, not stated.

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