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

With no annotations, the description carries the full burden of disclosing behavior. It only says 'Prompt discarded,' which is cryptic and possibly misleading—it could imply the tool ignores all input, yet the schema defines parameters that are described as being used for checks. There is no statement about network access, side effects, or what happens to the parameters. This is a serious gap for a tool with 9 parameters.

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 only one sentence, which is concise, but it is severely under-specified. It omits critical information about the template's content and the role of the parameters. The brevity is not an asset here; it is a symptom of incompleteness. A well-structured description would at least hint at the tool's purpose and usage context.

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 with 9 optional parameters, no output schema, and no annotations, this description is entirely inadequate. An agent has no idea what the template looks like, how the parameters affect it (if at all), or what the return value is. The tool appears to be a simple utility, but the description fails to give even a minimal mental model for correct invocation.

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 each parameter has a description in the schema, which already states they are 'discarded after' certain checks. The tool description adds no new meaning to the parameters—it does not clarify how the template might relate to any of them. Since the schema covers the parameters adequately, the baseline of 3 is appropriate, but the description does not add value beyond it.

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 the tool returns a 'three-step thinking template,' which names a clear verb and resource, but it does not explain what the template is for, what it contains, or how it differs from any sibling tool. The phrase 'Prompt discarded' is ambiguous, leaving the agent uncertain whether the tool processes any input at all. This is more than a tautology but far from a helpful purpose statement.

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?

No guidance is given on when to use this tool versus any of the 29 siblings. There is no mention of intended scenarios, prerequisites, or alternatives. An agent cannot infer whether this is a fallback for other tools or a specific utility. The description provides no usage context whatsoever.

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