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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states that the tool is browser-based and automatically judges/presents improvements, but fails to explain how it accepts input (no parameters), whether it opens a new page, what the user sees, or any side effects. This is a significant gap.

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 a single, front-loaded sentence that concisely conveys both the function and the browser-based nature. Every word earns its place, with no redundancy or unnecessary detail.

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 no annotations, no output schema, and zero parameters, the description provides only a high-level purpose and a minimal behavioral hint. It adequately conveys what the tool does but leaves ambiguity about how the agent should invoke it or interpret the result, especially since the 'improvement points' are not described in terms of output format or return value.

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 tool has zero parameters, so there is nothing for the description to clarify. The schema is empty and the description does not introduce any ambiguity, meeting the baseline of 4 for no-parameter tools.

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 clearly states the tool's function with specific verbs ('automatically determine' and 'present improvement points') and defines its scope (PASONA/AIDMA analysis for sales writing). This distinguishes it from sibling tools like cvr-improvement-checker, which focus on general CVR improvement.

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 implies usage for analyzing sales writing structure and improving conversion rate, and notes it is browser-based. However, it does not explicitly state when to choose this tool over alternatives or provide exclusion criteria, leaving the context implied rather than explicit.

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