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

Annotations already declare readOnly=true, idempotent, non-destructive and closed-world. The description adds substantial value beyond them by disclosing the return behavior (a procedural walkthrough of screens, buttons, fields) and that the tool performs no action itself. The trailing note that no self-serve API key exists further explains why browser automation is required.

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 purpose is front-loaded in the first clause, but the second and third sentences are long, semicolon-spliced, and the final sentence about the ProSolutions Paired host is only loosely connected to invoking this tool.

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 zero parameters, no output schema, and full annotation coverage, the description supplies everything needed to call it correctly, including the intended next step. The absence of any statement about output shape is acceptable only because the description paraphrases what it returns.

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 takes no parameters and the schema is fully self-describing, so the baseline is 4. The description adds no parameter meaning, but there is none to add.

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?

States a specific verb and resource ("List sales in the user's own Paired Plus account") and immediately clarifies the non-obvious twist that it returns step-by-step instructions rather than data. It does not explicitly differentiate itself from siblings like paired_plus_get_sales_insights or paired_plus_checkout_sale, which keeps it from 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?

Gives a clear follow-on condition: use the cotlet_browser_* tools in the Paired Plus Cloud Browser to actually perform the listed steps, and states it "opens nothing by itself." It lacks explicit when-not-to-use guidance or naming of the sibling list tools that return data rather than instructions.

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