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

The description mentions 'Prompt discarded,' which hints that the input is not used, but the schema already indicates parameters are discarded after shape checks. There is no disclosure of return format, side effects, or any other behavioral traits. With no annotations, the description carries full burden and fails to disclose much.

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 extremely short (one sentence), but this is under-specification rather than conciseness. It lacks essential information, so the structure does not aid the agent.

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?

With 9 optional parameters, no output schema, no annotations, and a very brief description, an agent cannot determine what the tool returns, how to invoke it correctly, or what the 'three-step thinking template' is. The description is critically incomplete.

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 9 parameters have schema descriptions (100% coverage), so the baseline is 3. The tool description adds nothing about parameters, so no additional value beyond schema.

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, but provides no detail on what that template contains or how it relates to the 9 input parameters. It does not distinguish itself from sibling tools like 'calc-eval' or 'browser-url-ok' – it's unclear what specific purpose it serves.

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 alternative. There is no mention of use cases, prerequisites, or exclusions.

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